P41205115SE002012-11-081TITLE:System and method for feeding the relative positions of a first and a second rotating component in relation to each other.
TECHNICAL FIELD:The present invention relates to a feed system for feeding the relative positions of a first rotating component and a second rotating component in relation to each other, comprising a first feeding unit arranged for mounting onThe first rotating component and a second feed unit arranged for mounting on the second rotating component; wherein at least one of said feed units comprises a detector unit for determining the positions of said rotating components. The invention also relates to a method for measuring the relative positions of a first component and a second component in relation toEach other, wherein the method comprises the steps of: mounting a first feed unit on a first rotating component; and mounting a second feed unit on a second rotating component, at least one of said feed units comprising a detector unit for determining the positions of said rotating components.TECHNICAL BACKGROUND:In several areas of technology, there is a need for a correct orientation of different components and machines in relation to each other. During operation of, for example, large notors, pumps and similar equipment, it is necessary that a first rotating component such as an output shaft of a driving unit, for example in the form of aMotor, is correctly aligned with respect to a second rotating component such as an input shaft of a driven unit, for example in the form of a pump. In this way, the output power of the motor can be transmitted via the rotational movement of the motor shaft to the input shaft of the pump in an optimal manner. Any misalignment between the two axles can result in poor efficiency and an increased risk of wear and damage.30 nnotor and pump.
As a -160 of these, there is a requirement in the above-mentioned technical field for correct alignment of the output motor shaft in relation to the input shaft of that pump. In thisIn this respect, it should be noted that the two axes can give rise to misalignment of iP41205115SE002012-11-082generality two different kinds. More specifically, the axes can be arranged at a certain angle in relation to each other, which is referred to as angular error, i.e. a "horizontal angular error" and a "vertical angular error". Second, the axes, although parallel to each other, may be slightly offset from each other so that theyextends along two separate directions, that is to say in parallel. This is called"horizontal offset" and "vertical offset". If these defects exceed predetermined spruce barriers, it can be assumed that the axes, and their associated machines, are poorly aligned in relation to each other. Their positions must then be adjusted so that a more optimal direction is achieved.
Thus, there is a general need for systems and methods for aligning various machine units including rotating shafts. Such systems and methods can be used for motors, pumps and similar equipment. In general, they can be used in power plants, chemical industries and oil refineries, especially in applications such asincludes high speed, or in applications that include expensive process criticalmachines which must be focused.
In accordance with prior art, described inter alia in SE 524366 and in US 4518855, an alignment of two rotatable shafts of two machines can be performed with the aid ofA food unit comprising a first feed unit arranged for mounting on a first machine and comprising a light source for generating light radiation in the direction of a second feed unit arranged for mounting on a second machine and also comprising a second light source for generating light radiation. in the direction of the first night unit. Furthermore, each of the food units comprises a detection unit foremitting light radiation. With the help of this apparatus can the alignment of the machinestwo axes are examined.
The alignment of the components or machines can be set manually by oneuser; usually a technician. This has led to a demand for systems that can calculate angular errors and offset errors as well as merge these values and the position of the components in a simple and clear way.
According to previous bachelors, traditional technology could focus on rotating components - e.g. in the form of rotating shafts - done by connecting the same components andP41205115SE002012-11-083then place them together in some predetermined angular layers along a vary, narnnare determined in true or some of the angular layers corresponding to 00, 90 °, 270 ° and 180 ° along the revolution. This approach was called the "clock method". Based on fitted angle and offset errors in each angle layer couldthe relative positions of the components are determined.
A disadvantage of the above-mentioned method is that it is not always possible for all types of machines and similar plants to position the rotating components.and their nnaten units, in all the above-mentioned angular laws. For example, it canoccur machine stalls where the flagon further machine part or similar star inthe wagon and prevents the axles from being flattened by these angles. For this reason, the above-mentioned traditional technique can be supplemented with the use of a so-called inclinometer, i.e. an angle feeder, which anyands to feed the current angle layer for each shaft, and associated feed unit. With this nnetod you can atthe direction anyanda itself of in principle arbitrary angular laws for each axis andnnatenhet. The respective installed angle layer can be fed up and then used in the calculations of angle and offset errors.
Furthermore, in accordance with prior art, a display unit has also been used,including, among other things, control unit and display, which is connected to the feed units. INthis solution the control unit receives the value Than the feed units and then calculates the alignment of the components via angular and offset errors. These values are added by the display unit via the display as numeric values and graphical information of the components. icons and indicators for how the component should be moved and how theirposition bar adjusted at the alignment can be shown on the display to facilitate forthe user.
The above type of food equipment is primarily intended to be used as the relevant onesThe machines are horizontally oriented, ie. as the input rotating axes arearranged along a common horizontal plane.
It should be noted, however, that for many applications, the machines are vertically oriented. There is thus a need for food equipment that has a flexibility forto be able to use saval for horizontally and vertically arranged components.
P41205115SE002012-11-084Analogously to this, there is a need for food equipment which includes display units which are also adapted for graphical display of data and images which can be applied to both horizontal and vertically arranged arrays of machines and similar units. It is otherwise black for the user to identify those valueswhich according to the display needs others then the graphic information on the display andthe arrangement of the physical components does not always agree.
Thus, it can be stated that there is a need for more flexible approaches for aligning rotating components, in particular for aligning arrangements whichnot not necessarily star horizontally arranged. There is also a need forthe market for increased ease of use and a clearer representation of the components on the display of a display unit for alignment of axle-driven machines.SUMMARY OF THE INVENTION:The present invention relates to a system and method for feeding the relative positions of a first rotating component and a second rotating component in relation to each other, comprising a first feeding unit arranged for mounting on the first rotating component and a second feeding unit arranged for mounting onThe second rotating component; wherein at least one of said feed units comprises a detector unit for determining the positions of said rotating components.
It is a spirit of the present invention to provide a food system withwhose helped an improved and in particular more flexible supply and focus of twocomponents' relative positions can be performed. In particular, it is an object to make a correct feed substantially independent of the orientation of the first and second components, respectively, regardless of whether the components are oriented along e.g. a substantially horizontal direction ora mainly vertical direction. A special spirit is to provide onenetwork systems that provide enhanced graphical information that reflects the arrangement of the physical components relative to the user in a clearer way known solutions.

BRIEF DESCRIPTION OF FIGURES:The present invention will now be described in detail with reference to the accompanying drawingsthe figures, wherein:figure 1 shows an arrangement of physical components connected to food unitsand the display unit according to the present invention;figure 2 shows an arrangement which in principle corresponds to figure 1 but in whichthe components are aligned substantially vertically; andP41205115SE002012-11-087Figures 3a-3b show an arrangement of physical components at different orientations, horizontal and vertical, respectively.
DESCRIPTION OF EMBODIMENTS:Figure 1 shows an arrangement 100 of a first component 1 and a second component2, the first component 1 being a drive unit such as, for example, a motor and the second component 2 being driven by the first component 1 and being, for example, a pump or a generator. The invention is not limited to use with a motor and a pump, but can be used for other types of uses of relativepositions between a first rotating component 1 and a second rotatingcomponent 2 under different operating conditions.
The output power of the first component 1 is transmitted to the second component 2 via an output shaft 3 of the first component 1, a coupling 4, and an input shaft.Axis 5 of the second component 2. The output shaft 3 and the input shaft 5 are each provided with feed units 6 and 7 for feeding and aligning the output shaft 3 of the notor 1 in relation to the input shaft 5 of the pump 2. In particular, the alignment can be evaluated. by determining the possible angular errors and offset values of the two axes 3, 5. The measuring units 6, 7 are mounted on theThe first component 1 and the second component 2, respectively, by means of a first mounting device 8 and a second mounting device 9, respectively.
In a preferred embodiment, shown in Figure 1, the first feed unit 6 comprises a first light source 10, which is preferably a laser light source arranged toprovide a first laser beam 11 directed at the second feed unit 7. Of thisThe second feed unit 7 comprises a light detector 12 arranged to detect incident light from the first light source 10. Furthermore, the second feed unit 7 may comprise a second laser light source 13 which is to produce a further laser beam 14 intended to be directed towards the first feed unit 6, in particular against an additionallight detector 15 arranged in said first food unit 6 and arranged to detectthe position at which the laser beam 14 is incident on the light detector 15. However, said night units 6,7 need not contain both a light source and a light detector. The advantage of two laser beams is more accurate feedings.
P41205115SE002012-11-088In a further embodiment, the first feeding unit 6 comprises a light source 10 below the second feeding unit 7 comprises a reflector for light from said light source 10 and the first feeding unit 6 comprises a detector 15 for light reflected via said reflector. According to a further embodiment, the only food unit may beprovided with a light skull, e.g. a laser light source, which is designed to generate lightwhich is incident on the other feed unit, which is then provided with a detector unit which in turn is constructed as two detector elements which are displaced longitudinally. In other words, the second feed unit is provided with a detector unit which can be used to divide the incoming light beam and real-time detectthe position in which the light beam is incident on the respective detector element. This canis used for a simultaneous determination of position and angle of incidence of the light beam if the two detector elements are axially offset, ie. along the same direction as the direction of the light beam. The invention thus comprises several different variants of food units with incoming light sources and detectors.
According to a further embodiment, the invention may comprise a detector in the form of an image sensor, e.g. in the form that can be provided in a camera. This image sensor is arranged on a feed unit and is arranged to detect the position of a graphic image, a sample or other graphic information, which is then imaged on the opposite side.nnatenheten.
Figure 1 further shows a mobile display unit 16 according to the present invention. The display unit 16 is preferably connected to at least one power supply unit 6, 7 via a wireless connection such as IEEE 802.11 type or Bluetooth. A wireless connection doesthe display unit 16 is easy to move around the stand 100. The connection can alsobe a physical connection such as an EIA-485 connection or an EIA-422 connection to at least one power supply unit 6, 7. The display unit is preferably of such a size that a user (not shown in the figure) of the display unit 16 can hold it in his hand.The display unit 16 has a display 17 such as an LCD screen with full VGA resolution. The display 17 shows graphical information which symbolically Merger the arrangement of the physical components 1, 2 in relation to each other. The graphic information is suitably in the form of three-dimensional views of the arrangement 100 with depictions of its main parts, viewed from a certain givenP41205115SE002012-11-089viewing angle. The display 17 can also be arranged to show numerical or other information regarding e.g. the dimensions of the components 1, 2 or other mats which are relevant for the alignment of the components 1, 2 in relation to each other.
The display unit 16 has a control unit 16a which is arranged to receive dataregarding the positions of the components 1, 2, data regarding dimensions of the components 1, 2 and the shafts 3, 5 and other integral parts in the housing 100, as well as relevant inboard distance between different parts in the housing 100. The control unit 16a is a land-based processor. The control unit 16a indicates, among other things, how alignment errorsto be calculated and what graphic information is to be displayed.
The feed units 6, 7 comprise a wireless or physical connection to the control unit inthe display unit 17. The feed units 6, 7 further comprise at least one motion sensor. The RO sensor can be an accelerometer or a gyro. An accelerometer is one typeof motion sensor which emits an electrical signal which is proportional to itspeed change, acceleration, the sensor exposed to. It can also be the karma of gravity, which means that it can be used as a legislator. In the embodiment, the accelerometer is used as a layer sensor, ie the canner of the direction in which the net units are located in relation to the direction of gravity. With the help ofFor this supply with the accelerometer, a value of the angular layer of the net unit can be obtained when the arrangement is in a horizontal position. You then get the function of an inclinometer which gives an absolute value of the angular layer of the respective feed unit 6, 7 at its rotation about the respective axis 3, 5. The accelerometer sends this user information to the display unit 16 for graphical presentation.
Figure 1 schematically shows a first gyro 18a and a first accelerometer 19a in the first feed unit 6, as well as a second gyro 18b and a second accelerometer 19b in the second feed unit 7. Thus it can be stated that the horizontally oriented arrangement 100 in figure 1 uses the first accelerometer 19a in the firstnnatenheten 6 fOr an angular feed, ie. for detecting an absolute value forthe angle of rotation of the first feed unit 6. The rotation of the angle of rotation is repeated in a plurality, e.g. three, different angular positions and is used together with the position information from the feed units 6, 7 for calculating any occurring angular and offset errors of the shafts 3, 5.
P41205115SE002012-11-08In the case where the accelerator 19a consists of a so-called a two-axis accelerometer can be used to detect whether the entire arrangement, including units 1, 2 is inclined in relation to the horizontal plane. This meant that the invention according to one suchembodiment can be used to determine which orientation is present innnatuppstallningen, ie. if it is horizontally or vertically oriented, or if it is oriented with a flag other - in principle arbitrary - angle of inclination in relation to the horizontal plane.The feed units 6, 7 may also comprise both a gyro unit and an accelerometer which feed direction and orientation of the feed units 6, 7 as they are moved by rotation.
The feed unit 6, 7 are arranged to assume a plurality of different rotational positions on the first onethe axis of rotation 3 and the second axis of rotation 5, respectively, during feeds to obtainthe values related to the positions of the first axis of rotation 3 and the second axis of rotation 5.
Figure 2 shows an arrangement 100 'which in principle corresponds to what is shown in figure 1,but which is arranged substantially vertically, i.e. with the rotating shafts 3,aligned mainly along a vertical plane. The components in Figure 2 which correspond to similar components according to Figure 1 have the same male reference numerals.
In the arrangement according to Figure 2, an accelerometer 19a in the first feed unit cannot6 is used to detect specific angular values for the first feed unit 6rotation, since the latter rotates only in the horizontal plane. Instead, the respective gyro 18a, 18b can be used to generate information about the angular layer of the respective food unit. More specifically, then, the respective gyro 18a, 18b will be used to detect the relative angle in relation to a reference value (whichthe user can select and set). In summary, the gyro can 18a, 18bis used to detect a change of direction, i.e. the angle in this case, when rotating the feed unit about the axis of rotation of the respective shafts 3, 4. A value of the angular layer has the respective unit of measurement in a number of rotational positions can then be supplied toP41205115SE002012-11-0811the control unit 16 to allow calculation of any occurring angular and offset errors.
Commercially available accelerometers and gyros are available as single-, two- and three-axismodels. The variants used according to the invention are preferably of three-axistype, which e.g. meant that a stand with saval gyro as accelerometer (of the three-axis type) can be used for scanning the angular position of the respective feed unit at the saval horizontal as well as vertical orientation of the respective stand 100, 100 '.
Furthermore, the use of an accelerometer can give a signal to the display unit 16 whichindicates whether the arrangement 100, 100 'is oriented vertically or horizontally. In addition, the arrangement can also be oriented at a different angle than completely vertically (as shown in Figure 2), ie where the entire arrangement 100 '(cf. Figure 2) can be said to be oriented along a line which has a certain angle in relation tothe horizontal plane. This medic & in turn an advantage of the invention, since itgraphics displayed on the display unit 16 can then be adapted so that the graphic images of the respective arrangement presented on the respective display 17 correspond to what they look like in reality.
It should also be noted that the principles of the invention may be re-implementedonly one of the food units includes accelerometer and gyro. This presupposes that the coupling 4 (cf. Figures 1 and 2) which connects the two rotating shafts 3, 5 does not show any patty play or the like, but that it forms a fixed connection where the shafts 3, 5 do not move in relation to each other. during feed.
The display unit comprises an orientation device for determining the orientation of the system for further graphical presentation.
In a basic form, the invention is based on at least one ofThe unit units 6, 7 comprise a gyro which can be used for an angular determination,more specifically, a detection of the current angular layer of the feed unit when rotating the two axes 3, 5. According to one embodiment, an accelerometer can also be used so that the gyro can be used in angular determination when the axes areP41205115SE002012-11-0812vertically oriented and the accelerometer can be used for angular determination as the axes are horizontally oriented.
Figure 3a shows an arrangement of a first component 1 and a feed unit 6 inhorizontal orientation in a coordinate system, ie the first component as well as itthe second component (not shown) is in this case arranged along a substantially horizontal axis, which in figure 3a corresponds to the x-axis. Said first component 1 represents the zero value on the x-axis. The accelerometer 18a (cf. Figure 1) can then be arranged to record data regarding acceleration in the direction of the y-axis (which corresponds toa certain rotation about the x-axis) and to send this data to the control unit.
According to the embodiment, the first feeding unit 6 also comprises a gyro 18a. A gyro is a type of sensor that can detect a change in rotational mode. The gyro 18a present in the first feed unit 6 can then - together with the accelerometer 19a in thefirst feed unit 6 - is used for a determination of the current angular layer for the firstthe unit of rotation 6 in the direction of rotation which is more accurate than if only the accelerometer 19a was used. This is therefore an advantage of using a first feed unit 6 which comprises both an accelerometer 19a and a gyro 18a, since they can then be arranged for accurate detection of the current angular layer when rotating the rotating shafts 3,5 as these are arranged with a substantially horizontal orientation as shown in figureThe second feed unit 7 may also comprise an accelerometer 19b and a gyro 19b for accurate detection of the position of the second feed unit 7 in the rotational direction.
The longitudinal direction of the arrangement 100 is shown in Figure 3a in a coordinate system in the form of x-longitudinal axis of the shaft. The longitudinal direction of the feeding unit 6 is thus perpendicular to the x-axis,which is the geometric position data of the food unit, for its starting position.
With continued feeding, the feed unit 6 will be rotated in the direction of rotation of the shaft 3. For example, the food unit 6 in a second layer will assume a rotational layer with a certainangle al in relation to the y-axis. This layer can be detected with the help of it inthe network unit 6 has the accelerometer 19a, which in this case is used as a tilt sensor. Any additional rotational strokes of the first feed unit 6 can also be detected and recorded by means of the accelerometer 19a. Information about the fed rotational law is passed on to the control unit 16a. Thus utilizedP41205115SE002012-11-0813the accelerometer 19a to generate the absolute value of the angular layer of the respective net unit.
Figure 3b shows the arrangement of a first component 1 and a feed unit 6 in verticalorientation a coordinate system. The gyro may be arranged to register rotation about the yaxis and to send this data to the control unit.
The gyro is given a starting position, from which it registers angular changes. The user indicates via user information to the display unit 13 when the network unit 6 is inthe starting position. This user information is converted into graphical information inthe display unit, which Merges as a three-dimensional image of the installation from a view and a perspective that corresponds to how a user (who hails in the display unit) actually views the installation.
The longitudinal direction of the arrangement 100 is shown in Figure 3b in a coordinate system in the form of y-longitudinal axis of the shaft. The longitudinal direction of the food unit 6 is thus perpendicular to the x-axis, which is the geometric position data of the food unit for its starting position.
With continued feeding, the feeding unit 6 will be moved in the shaft 3direction of rotation. For example, the food unit 6 in a second layer will assume onerotational position with a certain angle a2 in relation to the y-axis. This layer can be sensed by means of the gyro unit 19a included in the food unit 6, since the accelerometer 18a in the food unit 6 - which is used for sensing the inclination of the food unit 6 in relation to the horizontal plane - can not be used for sensingnamed angle layer a2. The gyro unit 19a, on the other hand, can be used for this layerdetecting the direction of rotation of the feed unit 6 about the y-axis. Thus, the angular layer a2 for this first rotational layer and any further rotational layers of the first feed unit 6 can be detected and recorded by means of the gyro unit 19a. Information about the fed rotational law is passed on to the control unit 16a.
It should be noted that information about the current rotational layers of the second feed unit 7 is also transmitted to the control unit 16a in connection with feeds, ie with the components 1, 2 oriented in e.g. horizontal or vertical direction. Analog withP41205115SE002012-11-0814As stated above, this information is generated by means of the accelerometer 18b and the gyro unit 19b in the second network unit 7.
According to one embodiment, information regarding the laws of rotation a1, a2 can be generated5 and is transferred from the respective feed unit 6, 7 regardless of whether the relevant components 1, 2 are oriented in horizontal or vertical direction. The invention can also be used to detect the current orientation of said first feeding unit 6 and said second feeding unit 7, respectively. The invention can also be used in principle if the relevant components 1, 2 are oriented "inclined", ie. along basically optionalangle in relation to the horizontal plane.
The invention is not limited to the above embodiments and examples, but is limited by the scope of the appended claims.As mentioned above, the graphical representations shown on the display unit 16 can be adapted to the values obtained Than respectively accelerometer and gyro, i.e. they can be adapted e.g. to the orientation of the rotating components to be aligned. In this way, a true-to-life image of the input components can be displayed on the display unit.
Furthermore, it can be stated that the display unit 16 shown in Figures 1 and 2 can be wireless, or alternatively wired. As a further alternative, the display unit may be built into any of the feeding units 6, 7 or into any other component belonging to the respective storage 100 of rotating components and feeding equipment.
Furthermore, the principles of the invention can be implemented by arranging an accelerometer and a gyro in a single feed unit. In order to achieve this, it is required that the coupling is arranged so that the [Ada rotating shafts 3, 5 are fixedly arranged next to each other and that they do not have any name for play. Furthermore, the namedaccelerometer and gyro of so-called three-axis type, but the invention is not limited tothis but can in principle be implemented even with single- and two-axis gyros and accelerometers.
