15 20 25 30 Gear transmissions are used in different contexts in a large number of different mechanical constructions. The flank play between the gears in the transmission of these mechanical constructions is of great importance for obtaining a functioning and reliable construction.
When a gear transmission is used to drive the camshaft of an internal combustion engine, there are a number of factors that the gear transmission must meet. In order to obtain accurate opening and closing times of the internal combustion engine valves, the camshaft between the gears included in the transmission must be carefully adjusted.
At the same time, as quiet a transmission as possible is desired in order to avoid noise, which can adversely affect the environment. If an internal combustion engine is to drive a vehicle, there are legal requirements in some countries on how high a noise level an internal combustion engine may generate.
The gear transmission used to drive the camshaft of the internal combustion engine often includes a plurality of gears which are engaged with each other. If the internal combustion engine has one or more overhead camshafts, the distance between the internal combustion engine crankshaft and the camshafts becomes significant. Thus, the transmission between the crankshaft and camshafts must include a number of gears. The crankshaft is mounted in the engine block and with overhead camshafts the camshafts are mounted in the cylinder head. Due to manufacturing technical tolerances of engine blocks and cylinder heads as well as existing seals and gaskets between these components in the assembled condition, the distance between crankshaft and camshaft will vary between internal combustion engines of the same type and make. For this reason, the wheelbase of the gears will vary depending on the components of the internal combustion engine being made with a certain torque.
During normal operation of the internal combustion engine, for example, a compression of the gasket of the cylinder head may occur. When servicing and repairing an internal combustion engine, the need for replacement or renovation, such as grinding, of the cylinder head may arise. Thus, the wheelbase of the gears can change during operation and after service and repair of the internal combustion engine. 10 15 20 25 30 It is previously known to arrange game adjustment mechanisms in gear systems, so that the gear settings between gears can be changed to be adapted to normal operation, wear, service and repair, which affects the gear play of the gears in the transmission.
It is also known to use game adjustment methods where an intermediate gear is arranged on an adjustable bracket to adjust the ﬂ ankle play between its cooperating gears.
WO9300530 discloses an adjustment mechanism for the center distance between gears in a gear transmission between crankshaft and camshaft of an internal combustion engine. An intermediate gear is rotated about an axis of rotation which is allowed when the fixing screws for the gear are loosened. The gear contains elongated grooves in which the fixing screws can run. When the center distance is correctly adjusted, the fixing screws are tightened, so that the position of the gear is fixed in relation to the engine block of the internal combustion engine.
US-A-3 502 059 discloses a gear adjustment mechanism in a gear transmission between crankshaft and camshaft of an internal combustion engine. An intermediate gear is arranged on a swivel bar console. When loosening a number of mounting bolts for the bracket, the bracket can be rotated about a pivot axis. When the correct gear is correctly adjusted, the mounting bolts are tightened so that the position of the bracket and the gear is fixed in relation to the cylinder head of the internal combustion engine.
SUMMARY OF THE INVENTION Despite known solutions in the field, there is a need to further develop a game adjustment mechanism which has a simple construction and which is easy to use. There is an additional need to further develop a game adjustment mechanism, which in manufacturing requires a small material requirement and which has a low manufacturing cost.
The object of the present invention is to provide a game adjustment mechanism which has a simple construction. A further object of the invention is to provide a game adjustment mechanism which is easy to use. Yet another object of the invention is to provide a game adjustment mechanism which requires a small material requirement during manufacture. Another object of the invention is to provide a game adjustment mechanism which exhibits a low manufacturing cost. These objects are achieved with a game adjustment mechanism of the type mentioned in the introduction, which is characterized by the features stated in claim 1. These objects are also achieved with a gear transmission. according to claim 11, an internal combustion engine according to claim 13, a vehicle according to claim 14 and a method for adjusting the flank play of a gear transmission according to claim 15.
By arranging a pin with a threaded portion and a conical portion in a bore in the gear, the anchor winch can be easily adjusted by turning the pin in the bore so that the center axis of the gear is displaced in parallel. The pin has a simple construction and is easy to use to adjust the anchor winch. When manufacturing the pin, a small material requirement is required, which also means that the pin has a low manufacturing cost.
According to one embodiment, the conical portion has an acute angle in the range 5 ° - 170 °, preferably in the range 135 ° - 45 °. Such an acute angle means that the gear is moved at the ﬂ anchor winch setting and that the parallel movement of the gear is ensured.
A misalignment of the gear would result in an incorrect pel winch or adjustment.
According to a further embodiment, the threaded portion has a thread pitch in the range 0.2 mm - 2 mm, preferably in the range 0.5 mm - 1.5 mm. Such a thread pitch entails a very accurate ﬂ ankle play adjustment, since the size of the thread pitch affects the axial movement of the pin when the pin is rotated. The axial displacement of the pin in turn affects the parallel displacement of the gear.
According to a further embodiment, the tip angle and the thread pitch are chosen so that when the pin is rotated 360 ° in the bore, the parallel displacement of the center axis ends up in the range 1 μm - 2 mm, preferably in the range Sum - 1 mm. Such a tip angle and thread pitch results in a very accurate ﬂ ankle play adjustment, since the size of the thread pitch affects the axial displacement of the pin when the pin is rotated. The axial displacement of the pin in turn affects the parallel displacement of the gear.
According to a further embodiment, a pivot shaft is arranged to extend through the gear wheel and parallel to the center shaft, so that the center shaft is displaced in parallel in a circular movement about the pivot shaft when the pin is rotated in the bore. Such a pivot axis means that the gear can be moved in a controlled direction during the ks ankle play adjustment, which affects the accuracy of the ﬂ ankle play adjustment and enables a uniform ﬂ ankle play adjustment against several gears at the same time.
According to a further embodiment, the bore comprises a conical step, which is designed to cooperate with the conical portion of the pin at the parallel displacement of the center axis. Such a conical step of the bore affects the accuracy of the ks play adjustment, since the surfaces of the conical portion of the pin and the conical steps of the bore will cooperate with each other during the flank adjustment when the pin is rotated in the bore.
According to a further embodiment, the conical step of the bore has an acute angle which substantially coincides with the acute angle of the conical portion of the pin. If the tapered step of the bore has an acute angle which substantially coincides with the acute angle of the pin conical portion, the accuracy of the ankle adjustment increases, since the surfaces of the tapered conical portion and the tapered bore of the bore will cooperate with each other during the ankle adjustment. According to a further embodiment, the threaded portion of the pin can be arranged in a threaded opening in a body part on which the gear wheel can be arranged. When the pin is rotated, the threaded portion of the pin will be rotated in the threaded opening of the body part. The pin will then be moved axially, which means that the conical portion of the pin ensures that the gear will be pressed axially against the body part at the same time as it is moved radially. As a result, the center axis of the gear wheel will be displaced in parallel, which results in a very accurate ﬂ ankle play adjustment.
According to a further embodiment, the bore comprises an internal thread, which is arranged to cooperate with the threaded portion of the screw. By designing the aisle in the borehole, the manufacture of the game adjustment mechanism is simplified.
According to a further embodiment, the conical portion of the pin is designed to cooperate with a conical recess in a body part on which the gear wheel can be arranged when the parallel displacement of the center shaft. By designing a conical recess in the body part and the passage in the borehole, the manufacture of the game adjustment mechanism is simplified.
According to a further embodiment, the gear transmission is arranged to transmit torque and rotation from a crankshaft to at least one camshaft of an internal combustion engine.
With such a gear transmission arranged between the crankshaft and the camshaft of an internal combustion engine, the camshaft between the gears included in the transmission can be easily adjusted. The simple design of the pin means that the ﬂ anchor winch can be adjusted very easily and accurately.
The method of adjusting the anchor winch according to the invention comprises the steps of placing the pin in the housing and rotating the pin so that the center axis is displaced in parallel. Such a method involves a very simple and accurate ks anchor winch adjustment, which can be performed with standard tools.
According to one embodiment of the method, a predetermined torque is applied to the pin, after which the pin is rotated a predetermined angle in the opposite direction, so that the center axis is displaced in parallel in the opposite direction. Thus, a simple and accurate ﬂ ankle play adjustment can be achieved with simple standard tools, such as a torque socket wrench.
According to a further embodiment of the method, the gear is fixed on a body part and the pin is removed from the bore. Since the pin is only to be used for the ﬂ ankle winch adjustment, it can be removed when the adjustment has been completed. This reduces the weight of the gear and the body part, for example an internal combustion engine, at which the gear is arranged.
Additional advantages of the invention will become apparent from the following detailed description.
BRIEF DESCRIPTION OF THE DRAWINGS In the following, by way of example, preferred embodiments of the invention are described with reference to the accompanying drawings, in which: Fig. 1 schematically shows a side view of a vehicle according to the present invention, Fig. 2 shows a plan view of a gear transmission with a Fig. 3 shows a sectional view along the line I -I in Fig. 2, Fig. 4 shows a sectional view of the game adjusting mechanism according to a first embodiment of the present invention, Fig. 5 shows a sectional view of the game adjusting mechanism according to a second embodiment, and Fig. 6 shows a plan view of a gear transmission with a game adjusting mechanism according to the present invention. DETAILED DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION Fig. 1 schematically shows a side view of a vehicle 1, which comprises a driveline 2 with an internal combustion engine 4, which is connected to a gearbox 6. The gearbox 6 is further coupled to the drive wheel 8 of the vehicle 1 via a propeller shaft 10. The internal combustion engine 4 is provided with a gear transmission 12 and a game adjusting mechanism 14.
Fig. 2 shows a plan view of a gear transmission 12 with a game adjusting mechanism 14 according to the present invention. The gear transmission 12 according to Fig. 2 comprises a first and second gears 16, 18, which engage with each other at the respective dividing or rolling circles 20. The center distance between the two gears 16, 18, which are mounted without an ﬂ winch, becomes the sum of the radii of respective gears 16, 18 dividing or rolling circles 20. Thus, the gears 16, 18 are shown in f1g. 2 mounted without ks anchor winch.
In Fig. 2 only a pair of teeth 22 per gear 16, 18 are shown. The dotted circles 24 schematically show that teeth 22 are arranged along the entire circumference of the gears 16, 18. To compensate for any further widening of the gears 16, 18, the center distance between the gears 16, 18 is usually increased slightly, so that an anchorage between the gears 16, 18 is obtained. During the thermal expansion of the gears 16, 18, otherwise large radial forces would arise between the gears 16, 18. If the radial forces between the gears 16, 18 are too great, the load on the gear bearing increases, which means that the service life of the bearings decreases. The large radial forces also increase the wear on the teeth 26 of the teeth 22, which can lead to a breakdown of the gears 16, 18 teeth 22 of the gears 16.
The gears 16, 18 are provided with mounting holes 28, so that the gears 16, 18 can be mounted on a frame 130, such as the engine block 32 or the cylinder head 34 of an internal combustion engine 4. The first gear 16 in ﬁ g. Fig. 2 is provided with a bore 36, which forms part of the game adjustment mechanism 14. Fig. 3 shows a sectional view along the line I -I in Figs. The first and second gears 16, 18 comprise a hub 38. The first gear 16 has a first center axis 39 and the second gear has a second center axis 41. The gears 16, 18 are rotatable on the hub 38 by means of plain bearings 40 and the gears 16, 18 are mounted on the body part 30 with screws 42. A mounting plate 44 arranged for each gear 16, 18 ensures that the gears 16, 18 are fixed axially. The first gear 16 is mounted on the body portion 30 so that the position of its first center shaft 39 can be adjusted radially relative to the body portion 30. The bore 36 in the first gear 16 extends substantially parallel to the first center axis 39. A pin 46 which forms a part of the game adjustment mechanism 14, can be arranged in the bore 36 and is formed with a threaded portion 48 and a conical portion 50. In fig. 3, and also in ﬁ g. 4 shows the pin 46 and the bore 36 according to a first embodiment of the invention.
The pin 46 is so arranged in the bore 36 that the first center axis 39 of the first gear 16 is pushed parallel when the pin 46 is rotated in the bore 36. To enable a radial movement of the first gear 16, the mounting holes 28 in the first gear 16 have a larger diameter is the diameter of the screws 42 which hold the first gear 16 against the body portion 38.
With the pin 46, the center distance of the gears 16, 18 and thus the anchor clearance can be adjusted by turning the pin 46 in the bore 36 so that the first center axis 39 of the first gear 16 is displaced in parallel.
A capercaillie device 51 can be arranged at the first gear 16, the kraft force of which must be overcome by the pin 46 during the ﬂ ankle play adjustment.
Fig. 4 shows a sectional view of a game adjustment mechanism 14 according to the first embodiment. The bore 36 comprises a conical step 52, which is designed to cooperate with the conical portion 50 of the pin 46 at the parallel displacement of the first center axis 39. Preferably, the acute angle t of the conical step 52 of the bore 36 coincides with the acute angle β of the conical portion 50 of the pin 46, so that the surfaces of the conical portion 50 of the pin 46 and the conical steps 52 of the bore 36 abut each other and co-operate with each other. during the ks ankle play adjustment when the pin 46 is rotated in the bore 36. This results in an accurate ﬂ ankle play adjustment.
According to the first embodiment, the threaded portion 48 of the pin 46 is arranged in a threaded opening 54 in the body part 30. When the pin 46 is rotated, the threaded portion 48 of the pin 46 will be rotated in the threaded opening 54 of the body part 30. The pin 46 will then be displaced axially. which means that the conical portion 50 of the pin 46 ensures that the first gear 16 will be pressed axially against the body part 30 at the same time as it is moved radially. Thus, the first center axis 39 of the first gear 16 will be displaced in parallel, which results in a very accurate ﬂ ankle play adjustment. An inclination of the first gear 16 in relation to the second gear 18 would give an incorrect ﬂ anchor play during the game adjustment.
The conical portion has an acute angle ß in the range 5 ° - 170 °, preferably in the range 135 ° - 45 °. Such an acute angle ß means that the first gear 16 for ﬂ is moved radially at the ﬂ angle of play setting and that the parallel displacement of the first gear 16 is ensured. The threaded portion 48 has a thread pitch in the range of 0.2 mm - 2 mm, preferably in the range of 0.5 mm - 1.5 mm. Such a thread pitch results in a very accurate ﬂ ankle play adjustment, since the size of the thread pitch affects the axial displacement of the pin 46 when the pin 46 is rotated. The axial displacement of the pin 46 in turn acts on the parallel displacement of the first center shaft 39 of the first gear shaft 16.
Preferably, the tip angle ß of the pin 46 and the thread pitch are selected so that when the pin 46 is rotated 360 ° in the bore 36, the parallel displacement of the first center axis 39 of the first gear 16 ends up in the range 1 μm - 2 mm, preferably in the range 5 μm - 1 mm. Such a tip angle ß and thread pitch entail a very accurate ﬂ ankle play adjustment, since the size of the thread pitch affects the axial displacement of the pin 46 when the pin 46 is rotated. The axial displacement of the pin 46 in turn acts on the parallel displacement of the first center axis 39 of the first gear shaft 16. Fig. 5 shows a sectional view of a game adjustment mechanism according to a second embodiment.
The bore 36 comprises an internal thread 56, which is arranged to cooperate with the threaded portion 48 of the pin 46. By forming the internal thread 56 in the bore 36, the manufacture of the game adjusting mechanism 14 is simplified. The conical portion 50 of the pin 46 is designed to cooperate with the first central axis 39. with a conical recess 58 in the body portion 30. Designing a conical recess 58 in the body portion 30 and the internal thread 56 in the bore 36 simplifies the manufacture of the game adjustment mechanism 14. The tip angle of the pin ß and the recess ot have dimensions corresponding to the intervals described in connection with the first embodiment above. The thread pitch of the pin 46 and the bore 36 also have dimensions corresponding to the intervals described in connection with the first embodiment above. Preferably, the tip angle ß and the thread pitch of the pin 46 are chosen so that when the pin 46 is rotated 360 ° in the bore 36, the parallel displacement of the first center axis 39 of the first gear 16 ends up in the range 1 μm - 2 mm, preferably in the range 5 μm - 1 mm .
Fig. 6 shows a plan view of a gear transmission 12 with a game adjusting mechanism 14 according to the present invention. According to Fig. 6, the gear transmission 12 is designed for camshaft operation of the internal combustion engine 4. The gear transmission 12 comprises a number of gears which are in engagement with each other. The internal combustion engine 4 has two overhead camshafts 60 and the distance between the crankshaft 62 of the internal combustion engine 4 and the camshafts 60 is substantial. Thus, the transmission 12 between the crankshaft 62 and the camshafts 60 must include a number of gears. The crankshaft 62 is mounted in the engine block 32 of the internal combustion engine 4 and the camshafts 60 are mounted in the cylinder head 34 of the internal combustion engine 4. Due to manufacturing technical tolerances of the engine block 32 and the cylinder head 34 and the existing gasket 63 between the engine block 32 and the cylinder head 34, the distance between the camshaft shaft 62 60 to vary between internal combustion engines 4 of the same type and make. For this reason, the wheelbase of the gears will vary depending on the fact that the components of the internal combustion engine 4 are manufactured with a certain tolerance. During operation of the internal combustion engine 4, a compression of the gasket 63 may occur. During service and repair of the internal combustion engine 4, the need for replacement or renovation, such as grinding, of the cylinder head 34 may arise. This allows the wheelbase of the gears to change during operation and after service and repair of the internal combustion engine 4.
I f1g. 6, the first gear 16 is adjustably arranged between the gears 64 of the respective camshafts 60. A third gear 66 is adjustably arranged between the first gear 16 and the gear 6 of the crankshaft 62. The third gear 66 preferably has a game adjustment mechanism 14 according to the upturn. A pivot shaft 70 is arranged to extend through the third gear 66 and parallel to the third center axis 67 of the third gear 66, so that the third center axis 67 of the third gear 66 is displaced in parallel in a circular motion about the pivot shaft 70 when the game adjusting mechanism 14 displaces the third gear 66 Such a pivot shaft 70 causes the third gear 66 to move in a controlled direction during the flank play adjustment, which affects the accuracy of the ﬂ play play adjustment and enables a different ﬂ ankle play adjustment against the first gear 16 and the gear shaft 62 gear 62.
After adjusting the angle of play between the first gear 16 and the gears 64 of the camshafts 60 by means of the play adjusting mechanism 14 of the first gear 16, the angle of play between the third gear 66 and the first gear 16 is adjusted by the gear of the gear shaft the third gear 66. When the play adjustment mechanism 14 of the third gear 66 displaces the third center axis 67 of the third gear 66 in a circular motion about the pivot axis 70, depending on the position of the pivot shaft 70 relative to the third center axis 67 of the third gear 66 and the fourth axis of the crankshaft 65 , the movement of the gears between the three gears to become different sizes. This can be advantageous in the described ﬂ ankle adjustment operation, since a larger ﬂ ankle adjustment is reasonably needed between the first and third gears 16, 66, compared between the third gear 66 and the gear shaft 62 gears 68.
The method for adjusting the anchor winch according to the invention is shown in the block diagram in f1g. 7 and includes the steps of a) mounting the pin 46 in the bore 36 and b) rotating the pin 46 so that the first center axis 39 is displaced in parallel. Such a procedure entails a very simple and accurate ﬂ ankle play adjustment, which can be performed with standard tools.
Further c) a predetermined torque is applied to the pin 46, after which d) the pin 46 is rotated a predetermined angle in the opposite direction, so that the first center axis 39 is displaced in parallel in the opposite direction. Thus, a simple and accurate ﬂ ankle play adjustment can be achieved with simple standard tools, such as a torque socket wrench. The parallel displacement of the first center shaft 39 in the opposite direction can be effected by the force of gravity acting on the first gear 16. Alternatively, the spring force from the spring device 51 (ﬁ g. 3) can parallel shift the center shaft 39 in the opposite direction.
Finally, e) the first gear 16 is fixed to a body portion 30 and f) the pin 46 is removed from the bore 36. Since the pin 46 is to be used only in the ﬂ winch adjustment, it can be removed when the adjustment has been completed. Thereby the weight of the transmission 12 and the body part 30, for example an internal combustion engine 4, at which the transmission 12 is arranged is reduced.
The stated components and features stated above can be combined within the scope of the invention between different specified embodiments.
