    [0001] The invention relates to mounting annular components, for example bearings, on a shaft. In particular, the invention can be used to mount components with a tapered bore on a complementary shaped shaft section. An example of this field is the mounting of a bearing on a frustoconical bearing. During the assembly of such objects, internal stresses are generated, thus achieving a clamping fit. The conical object is stretched, while the tree is compressed. The objects involved may be various technical or engineering components, such as gears, bearings, etc. Although high internal stresses lead to a properly tightened fit, care must be taken not to overload objects to prevent creep and crack development. On the other hand, the low stresses are also to be avoided, considering the problems of fretting-corrosion or corrosion under stresses. Applicant has previously disclosed a method in US5779419 for mounting an annular component having a conically shaped aperture on a conical shaft which provides a predictable result. This method comprises the steps of: installing the hollow object on the shaft so as to bring the conically shaped surfaces of said object and said shaft into a bearing relationship; driving the annular component to a starting position to establish an initial adjustment with tightening; and driving the component a predetermined distance from the initial position to a final position to establish a final tightened fit. This approach relies on the correct intervention of a user by actuating a pump by referring to tabulated data so as to obtain the desired initial support force and the desired subsequent displacement. The Applicant has discovered that operator imprecision is exacerbated by the imprecision of the typical gauges used to measure pressure and displacement, and also by the imprecision of manual actuation of the typically used hand pump. to establish the desired pressure. According to the invention, a system is set up by means of which the annular component can be mounted more precisely, faster and with less reliance on the operator. Typically, the component is a bearing, such as a rolling element bearing.
    [0002] For a better understanding of the invention, and to show how it can be practiced, reference will now be made, by way of example only, to the accompanying drawings, in which: Figure 1 shows an arrangement according to state of the art for use by an operator; Figure 2 shows a schematic representation of the steps of the method according to the state of the prior art; Figure 3 shows an embodiment of the invention; and Figure 4 shows a schematic representation of an example of a remote control device for use in the invention. Figure 1 shows a spherical roller bearing 1, having an inner ring 2, which is provided with a conically shaped bore, an outer ring 3 with a spherical race, and two rows of rollers 4. The Spherical roller bearing 1 is being mounted on the nozzle 5, comprising a portion 6 of conical shape, and a threaded portion 7 forming a screw. A hydraulic nut 8 has been screwed onto the threaded portion 7 forming a screw. This hydraulic nut 8 comprises a nut body 9 which is provided with a coaxial annular chamber 10. In said chamber 10, a piston 11 similar to a ring has been slidably housed. By means of gaskets 12, the piston 11 has been made leakproof with respect to the cylindrical walls of the chamber 10. By means of the connection 13, the chamber 10 is connected to a hydraulic hose 14, which is itself connected to a hose 14. hydraulic pump 15 hand. The oil can be pumped from the pump 15 by raising and lowering the handle 16. The pressure gauge 17 indicates the oil pressure. As illustrated in FIG. 1, the piston 11 bears against the inner ring 2 of the spherical roller bearing 1. By pumping oil into the chamber 10, the ring 2 is pressed along the conical portion 6 of the nozzle 5. The piston 11 is also provided with a flange 18 oriented radially outwards, against which the key 19 of measurement is supported. This key is part of the distance measuring device 20, which contains an envelope 21 with screw thread screwed into the bore 22 formed in the nut body 9. The dial indicator 23 is connected to the axially movable key 19, so as to allow the measurement of the relative axial displacement between the nut body 9 and the piston 11. During assembly of the spherical roller bearing 1 on the 5, the bearing 1, in particular its inner ring 2, is threaded onto the end piece 5 until the conically shaped surfaces of the inner ring 2 and the end piece 5 are on top of each other. . In this position, no or almost no clamping action exists yet. This position of the spherical roller bearing is indicated by A (zero position) in Figure 2. Thereafter, the inner ring 2 is depressed to the starting position B, pumping oil into the chamber 10 When the starting position B has been reached, the inner ring 2 is pressed a distance Ss towards the end position C. With the reference S, the distance between the position where the bearing is placed by hand and the final position has been indicated.
    [0003] Figure 3 shows an embodiment of a system of the invention comprising a hydraulic nut 100, a pump 115 and a remote control device 200. In Figure 3, similar items to those of Figure 1 have been illustrated with the same reference numbers.
    [0004] The pump 115 may be a hand pump, a motor pump and / or an electrically actuated pump. 3 3032 13 9 2014P00559EN The hydraulic nut 100 is arranged to be fixedly mounted on the shaft, for example by being clamped on the shaft, or by being screwed onto a thread on the shaft. The hydraulic nut 100 has a nut body 9 which is provided with a coaxial annular chamber. In said chamber 10, a ring-like piston 11 has been slidably housed. Preferably, seals 12 are incorporated to make the piston 11 sealed with respect to the cylindrical walls of the chamber 10. The chamber 10 is connected to a hydraulic or pneumatic hose 14, which is connected to the pump 115. Fluid may be pumped from the pump 115 into the chamber 10 via the hose 14. The hydraulic nut 100 may include an electric pressure sensor 117 for providing an electrical signal indicative of the pressure inside the chamber 10. The pressure sensor 117 communicates wirelessly with other devices via a wireless pressure transmitter 118. The wireless pressure transmitter 118 may communicate with other devices via Bluetooth or another wireless communication protocol as is known in the art. While the pressure sensor 117 and the wireless transmitter 118 of this embodiment are part of the hydraulic nut 100, they may instead be embodied in the pump 115 (since Pumping represents the pressure in the chamber 10), or as a separate device attached to the hose 14. The pump 115 is arranged to pump fluid into the chamber 10. This can generate a force to drive the ring 2 In the illustrated embodiment, the pump 115 includes a wireless pump receiver 116 and is capable of wireless communication with other devices. Preferably, the wireless pump receiver 116 may receive instructions by which it controls the pump 115 using other devices. The wireless pump receiver 116 can communicate with other devices via Bluetooth or another wireless communication protocol as is known in the art.
    [0005] In embodiments where the pressure sensor 117 is part of the pump 115, the wireless pump receiver 116 and the wireless pressure transmitter 118 may be a single communications device. The hydraulic nut 100 includes an electrical distance measuring device 120 for providing an electrical signal indicative of the displacement of the piston 11 within the chamber 10. The distance measuring device 120 communicates wirelessly with other devices. via a wireless transmitter 125 of displacement. The wireless traveling transmitter 125 can communicate with other devices via Bluetooth or another wireless communication protocol as it is known in the art. The remote control device 200, shown in more detail in FIG. 4, comprises: a display 205; a communication device 210; and input means 225. In some embodiments, the display 205 and the input means 225 are collectively constructed as a touch screen 205, 225. The input means 225 is arranged to receive a user input. . The communications device 210 is configured to wirelessly receive signals from the wireless transmitter 118 and the wireless transmitter 125 for movement. Preferably, the communications device 210 is configured to provide wireless control signals to the wireless pump receiver 116 for controlling the pump 115. For example, the communications device 210 may send user instructions obtained to from the input means 225 to the pump 115 for its control, e.g. to turn the pump on or off. The display 205 is appropriately configured to display a mark representing the signals received by the communications device from the pressure transmitter 118 and the wireless transmitter 125 of movement.
    [0006] The remote control device 210 may be configured to display first information representing the pressure in the chamber 10 and second information representing the movement of the piston 11. Preferably, the remote control device 200 includes a memory for storing data. The data can be entered via the input means 225 or, alternatively, they can be accessed from a remote server. The data may include one or more of: the mounting arrangement (eg whether it is with or without a socket, and the type of socket); the type of hydraulic nut; the type of bearing; the reduction of the game; the number of previous montages; the material of the tree; and / or the bore size of the shaft (if any). While in some embodiments, the input or access data may include the desired pressures and displacements for one or more types of components, in other embodiments, the pressure and The desired displacement can be calculated using the remote control device 200 from the inputted or accessed data. In some embodiments, the display 205 displays both the first information and the second information. The indicator may vary depending on the actual pressure, the initial pressure and the desired pressure, or depending on the current displacement, the initial displacement and the desired displacement. In this way, the indicator can represent one or other of these quantities in a simple, precise and easy to interpret manner. Advantageously, this relieves the operator of referring to tables to determine how to operate the pump 115. In general, the indicator may indicate the proportion of a range from an initial value to a desired value reached by the pump. pump 115 and the hydraulic nut 100, regardless of whether it is a pressure or a displacement. In some embodiments, a first mode is set up, where the display 205 displays the first information and does not display the second information, and a second mode is set up, where the display 205 displays the second information. and do not display the first information. Optionally, the display 205 may automatically switch from the first mode to the second mode (i.e. without requiring operator intervention). In these embodiments, the remote control device 210 may be configured to display a single indicator, which may represent the first information in the first mode and the second information in the second mode. In some embodiments, the indicator is arranged to indicate the proportion of a range from an initial value of pressure to a desired value of pressure when the pressure is between the initial value of pressure and the desired value. pressure. Once the desired pressure has been reached, the indicator may stop indicating the proportion of pressure, and instead indicate the proportion of a range from an initial value of displacement to a desired value of displacement.
    [0007] The indicator may be, for example, a progress bar that fills or a traffic light that changes from red to orange then green. In preferred embodiments, the indicator is arranged to indicate the progress of the entire mounting procedure (ie both the step of achieving the desired pressure and the step of which follows to achieve the desired displacement). The operator may continue to operate the pump 115 (either manually or electrically operated via input means 225) until the indicator indicates that the process has been completed. With such an indicator, the operator may not be able to see which of the steps (whether to achieve the desired pressure or the desired displacement) is currently in progress.
    [0008] The indicator can represent the progression so that the first half of the progression goes from the initial value of pressure to the desired value of pressure and the second half of the progression goes from the initial value of displacement to the desired value of displacement. In this case, the desired pressure value corresponds to the initial displacement value. As a first example, the indicator may be a graphical representation of a bar that fills as the procedure progresses, wherein the first half of the bar represents a range from the initial value of pressure to the desired value. The second half of the bar indicates the proportion of a range from the initial value of displacement to the desired value of displacement. As a second example, the indicator can be a color representation that changes color through a predetermined sequence of colors from a start color, through intermediate colors, to an end color (e.g. from red to orange to green - the standard colors of a "traffic light") as the procedure progresses. The start color (eg green) can represent the initial pressure value, the intermediate color (eg orange) can represent the desired pressure value and the initial displacement value, and the final color (by red) can represent the desired value of travel. An operator can use the indicator displayed on the display 205 to establish when and how to operate the pump 115 (whether by manual operation, or electrically via the input means 225). In a second embodiment, the system is configured in such a way that the one component mounting process, such as a bearing, can be triggered by a single starting instruction issued by an operator, for example via the means 225 of Entrance. Suitably, the start setpoint is issued after data on the bearing and the mounting arrangement have been entered using the input means 225. For example, an operator would thread the bearing 1 onto a conical shaft 5 until the tapered bore of the bearing 1 and the outer surface of the shaft 5 are on top of each other. In this position, there is no or almost no significant clamping action. The operator can then mount the hydraulic nut 100 on the shaft 5. This position of the bearing 1 is indicated by A (zero position) in Figure 2.
    [0009] The operator can then issue the start command, in response to which the remote control device 200 is programmed to perform the following steps: (1) issue a control signal to activate the pump 115. The control signal can be sent from the communication device 210 to the wireless receiver 116 of the pump. (2) Receiving a pressure signal from the wireless pressure transmitter 118 using the communication device 210. (3) Compare the received pressure signal to a pressure threshold. The pressure threshold may be either a threshold stored on the remote control device 210 or obtained from a remote server. (4) When the received pressure signal reaches the pressure threshold, receive a first displacement signal from the wireless transmitter 125 of displacement. In fact, the distance measuring device 120 can be inactive until this step and can only be activated once the pressure threshold has been reached. Likewise, the pressure sensor 117 can be deactivated when the threshold is reached. (These communications may be made via transmitters 116 and 125, which may also be receivers). 9 14P00559EN (5) Calculate a displacement threshold. This can be calculated, for example, by adding a desired displacement (Ss in FIG. 2) to the current displacement as indicated by the first displacement signal. The desired movement can be either a threshold stored on the remote control device 210, or obtained from a remote server. (6) Receive an additional motion signal (or continue to receive the same signal) from the wireless traveling transmitter 125. Once the pressure threshold has been reached, the wireless traveling transmitter 125 can continue to emit displacement signals. (7) Compare the additional motion signal received at the displacement threshold. (8) When the received movement signal reaches the displacement threshold, outputting a control signal to turn off pump 115. The control signal can be sent from communication device 210 to wireless pump receiver 116. (9) Deliver an output signal (e.g., audibly or via display 205) after a predetermined period of time. The predetermined period of time may be either a threshold stored on the remote control device 210 or obtained from a remote server.
    [0010] In response to step (1), the pump 115 pumps fluid into the chamber 10 of the hydraulic nut 100, thereby driving the bearing 1 to the starting position B. Following step (4) , position B will have been reached. Following step (8), the bearing 1 has been depressed over a distance Ss and will have reached the end position C. Between steps (8) and (9), any lubricant present between the bearing 1 and the shaft 5 escapes. 10
