Example 1

The embodiment provides a sliding block assembly for a bearing, which comprises a base 305, a sliding part 311 and a height adjusting mechanism, wherein the base 305 can support, limit and restrain the sliding part 311, the shape of the base 305 can be determined according to actual requirements, and preferably, as shown in fig. 1, the base 305 can preferably adopt a square-block-shaped structure.

In this embodiment, the sliding member 311 is movably constrained to the base 305 and is in transmission fit with the height adjusting mechanism; as shown in fig. 1-3, a side of the sliding component 311 facing away from the base 305 is configured with a first sliding engagement surface 304, and the first sliding engagement surface 304 is located above the base 305, so that when the present slider assembly 300 is disposed between the inner ring 200 and the outer ring 100 of the bearing, the first sliding engagement surface 304 can just fit into the second sliding engagement surface 202 configured on the inner ring 200 or the outer ring 100 of the bearing.

In this embodiment, the height adjusting mechanism is mainly used for adjusting the height of the sliding component 311 along the height direction 303 of the base 305, i.e. the sliding component 311 can move relative to the base 305, so that a worker can adjust the height of the sliding component 311 along the height direction 303 of the base 305 through the height adjusting mechanism to change the height of the whole slider assembly 300, thereby achieving the purpose of adjusting the size of the gap between the first sliding engagement surface 304 and the second sliding engagement surface 202. Specifically, after the slider assembly 300 is mounted between the bearing outer ring 100 and the bearing inner ring 200, in the bearing using process, the gap between the first sliding fit surface 304 and the second sliding fit surface 202 can be adjusted by adjusting the height of the sliding component 311, as shown in fig. 12, so that the gap between the first sliding fit surface 304 and the second sliding fit surface 202 can be adjusted, and by adopting such a design, on one hand, the problem that the size of the bearing gap cannot meet the optimal design requirement due to errors in the bearing production and assembly process can be effectively solved; on the other hand, the staff can regularly or after discovering that the first sliding fit surface 304 is worn and the clearance is increased, adjust the clearance size between the first sliding fit surface 304 and the second sliding fit surface 202 by adjusting the sliding block assembly 300, so that the large clearance between the first sliding fit surface 304 and the second sliding fit surface 202 reaches the optimal design requirement again, so that the bearing can continue to operate in the optimal operating state, and the circulation can effectively solve the problems of wear aggravation, unstable operation, damage and the like of the bearing due to the excessive clearance, ensure that the bearing can be operated with high precision, long service life and stable operation, so that the bearing provided with the sliding block assembly 300 can effectively meet the requirement of the wind power generation system for longer service life, and can effectively prevent the problems of midway disassembly, maintenance and replacement.

In order to enable the sliding component 311 to move strictly along the height direction 303 of the base 305 under the driving of the height adjusting mechanism, the base 305 is configured with a first restriction portion, at this time, the sliding component 311 can be configured to be matched with the first restriction portion, so that the sliding component 311 and the first restriction portion can form a moving pair along the height direction of the base 305, namely, the first restriction portion not only can play a role of limiting and restricting the sliding component 311, but also can play a role of guiding the movement of the sliding component 311. In practice, the first restriction portion has various embodiments, for example, the first restriction portion may be a guide cavity 307 configured in the base 305 and extending through the upper end of the base 305, as shown in fig. 1, 5-9, at least the lower end of the sliding member 311 is movably constrained in the guide cavity 307, and the side wall of the sliding member 311 may be configured to fit the side wall of the guide cavity 307, so that the sliding member 311 can vertically ascend/descend under the constraining and guiding effects of the guide cavity 307. As another example, the first constraining portion may also be a guide bar provided to the base 305 in the height direction of the base 305 (i.e., the height direction 303 of the base 305), and accordingly, the slide member 311 is configured with a guide hole adapted to the guide bar so that the slide member 311 can be raised/lowered under the guide of the guide bar. For another example, the first constraint portion may also be a groove formed in the base 305, a side wall of the groove is configured with a guide groove distributed along the height direction, and a side of the sliding member 311 is limited and constrained in the guide groove, so that the sliding member 311 can ascend/descend under the constraint of the guide groove.

In this embodiment, the height adjusting mechanism mainly plays a role of jacking, and has various embodiments, for example, the height adjusting mechanism may be an existing telescopic mechanism, so as to drive the sliding member 311 to move by extension/contraction, thereby achieving the purpose of adjusting the position and height of the sliding member 311. For another example, the height adjusting mechanism may be an existing lifting mechanism, so that the sliding member 311 is driven to move by the lifting/lowering action, and the purpose of adjusting the position and height of the sliding member 311 can also be achieved.

In a preferred embodiment, the height adjustment mechanism includes a jacking component 315, as shown in fig. 4 to 9, the jacking component 315 is movably disposed below the sliding component 311 and is in transmission fit with the sliding component 311, and the jacking component 315 is mainly used for supporting the sliding component 311 and jacking the sliding component 311 upwards along the height direction 303 of the base 305. Specifically, the lifting member 315 can lift the sliding member 311 upwards along the height direction 303 of the base 305, so as to adjust the height of the sliding member 311. And after the jacking component 315 adopts a jacking mode to adjust the height of the sliding component 311, the jacking component 315 can play a role in supporting the sliding component 311, so that the load on the sliding component 311 can be transmitted to the bearing inner ring 200 or the bearing outer ring 100 through the jacking component 315, and the bearing capacity of the sliding component 311 and the whole sliding block assembly 300 can be obviously improved. In this embodiment, since the jacking member 315 adopts a jacking manner to adjust the height of the sliding member 311, the jacking member 315 needs to perform a linear motion during jacking.

In order to make the jacking component 315 strictly move linearly under the action of external force, in a more sophisticated solution, the jacking component 315 further comprises a second constraint portion, and the jacking component 315 may be configured to adapt to the second constraint portion. In one embodiment, the lifting member 315 may form a moving pair with the second restriction portion along the height direction of the base 305, for example, the lifting member 315 may be an adjusting screw, the second restriction portion may be a threaded hole 309 adapted to the adjusting screw, the adjusting screw may be connected to the threaded hole 309 by a thread, the threaded hole 309 may be configured at the bottom of the base 305, the adjusting screw may be assembled below the sliding member 311, the upper end of the adjusting screw abuts against the bottom end of the sliding member 311, and the lower end of the adjusting screw extends out of the threaded hole 309 and is configured with a screwing head 318. In the actual use process, the staff can rotate the adjusting screw through the twisting tool so as to drive the adjusting screw to linearly move, and therefore the sliding part 311 can be lifted upwards, and the purpose of adjusting the gap is achieved.

In another preferred embodiment, the lifting member 315 and the second constraint part may form a moving pair perpendicular to the height direction of the base 305, that is, the lifting member 315 may move transversely under the constraint and guide of the second constraint part, so as to lift the sliding member 311. For example, the jacking member 315 and the sliding member 311 are respectively configured with a first wedge-shaped surface 316 and a second wedge-shaped surface 313 which are adapted to each other, as shown in fig. 2-9, wherein the first wedge-shaped surface 316 faces the top end of the base 305, and the second wedge-shaped surface 313 faces the bottom end of the base 305; along the height direction 303 of the base 305, the jacking component 315 is limited and restricted below the sliding component 311 by the second restriction part, as shown in fig. 5-9, at this point, the second wedge-face 313 may just abut against the first wedge-face 316, when the height is adjusted, the sliding component 311 can be driven to rise only by driving the jacking component 315 to move along the direction vertical to the height direction (i.e. transverse direction) of the base 305, thereby achieving the purpose of jacking the sliding component 311, moreover, the jacking component 315 and the sliding component 311 can realize the surface-to-surface contact transmission through the first wedge-shaped surface 316 and the second wedge-shaped surface 313, transmit the power through the matching of the second wedge-shaped surface 313 and the first wedge-shaped surface 316, the load-bearing performance of the sliding member 311 and the present slider assembly 300 can be significantly improved, so that the present slider assembly 300 can be competent as a main bearing in a wind power generation system. In this embodiment, the second constraining portion also has various embodiments, for example, the second constraining portion may be a transverse groove 308 formed in the base 305, the transverse groove 308 is perpendicular to the height direction 303 of the base 305, and the jacking member 315 is configured to fit into the transverse groove 308 and form a moving pair with the transverse groove 308. For another example, the second constraining portion may be a transverse channel configured on the base 305, and the lifting member 315 is configured to fit the transverse channel and form a moving pair with the transverse channel, so that the transverse slot 308 can constrain and guide the lifting member 315, and the same effect can be achieved. Furthermore, the second constraining portion may be configured not only on the base 305, but also on the sliding component 311, for example, the second constraining portion may be a transverse groove 308 configured on the sliding component 311, as shown in fig. 2-6, the transverse groove 308 is perpendicular to the height direction 303 of the base 305, the jacking component 315 is configured to fit the transverse groove 308 and form a moving pair with the transverse groove 308, as shown in fig. 5 and 6, preferably, the second wedge surface 313 may be configured as the bottom surface of the transverse groove 308, and two side surfaces of the transverse groove 308 may be just used for constraining the jacking component 315.

It can be understood that, since the first constraining portion and the second constraining portion can be configured on the base 305, in implementation, the second constraining portion and the first constraining portion can be configured on the base 305 separately, or can be configured on the base 305 in a mutually communicated manner, for example, when the first constraining portion adopts the guide cavity 307, the bottom surface of the guide cavity 307 and two side surfaces parallel to each other on two sides of the bottom surface can form the second constraining portion, as shown in fig. 7, the three can just form the transverse groove 308 for constraining the jacking component 315, and at this time, the side wall and the bottom surface of the jacking component 315 can be configured to be adapted to the second constraining portion. For another example, when the first restriction portion is the guide cavity 307, the second restriction portion may be a transverse slot 308 formed in the sliding member 311, and the transverse slot 308 faces the bottom of the guide cavity 307, the jacking member 315 may preferably be a wedge-shaped block, as shown in fig. 4-6, and is assembled at the bottom of the guide cavity 307, and the upper portion of the jacking member 315 is constrained in the transverse slot 308, as shown in fig. 2-6, so that the jacking member 315 can move transversely under the support of the bottom of the guide cavity 307 and the constraint of the transverse slot 308; the lower end of the sliding component 311 is located in the guide cavity 307, and four side walls of the guide cavity 307 can play a role in restraining and guiding the sliding component 311, so that the sliding component 311 can be driven to ascend when the jacking component 315 transversely moves, and by adopting the design, the whole sliding block assembly 300 is simpler and more compact in structure and higher in bearing capacity.

In a more complete solution, the height adjustment mechanism further includes an adjustment member 317 and a threaded hole 309 configured on the base 305, as shown in fig. 1, 4, 5 and 7, the adjustment member 317 is configured with an external thread 320 configured to fit the threaded hole 309, so that the adjustment member 317 can be screwed into the threaded hole 309, two ends of the adjustment member 317 respectively extend out of the threaded hole 309, one end of the adjustment member 317 can abut against the jacking component 315 and can also be rotatably connected to the jacking component 315, and the other end is configured with a screwing head 318 configured to fit a screwing tool. When the adjusting member 317 abuts against the jacking component 315, as shown in fig. 4, 5 and 8, the jacking component 315 can be driven to move only in one direction; specifically, the worker rotates the adjusting member 317 through the twisting tool, so that the adjusting member 317 can be driven to move linearly relative to the threaded hole 309, and the jacking member 315 is driven to move linearly along the second restriction portion, so that the sliding member 311 can be driven to ascend along the height direction 303 of the base 305, and the height of the sliding block assembly 300 can be effectively adjusted. When the adjusting member 317 is rotatably connected to the jacking component 315, the jacking component 315 can be driven to move bidirectionally; specifically, the worker rotates the adjusting member 317 through the twisting tool, so that the adjusting member 317 can be driven to move linearly relative to the threaded hole 309, and the jacking member 315 is driven to move linearly along the second restriction portion, so that the sliding member 311 can be driven to ascend/descend along the height direction 303 of the base 305, and the height of the sliding block assembly 300 can be effectively adjusted. In practice, the screwing head 318 may be a hexagon socket, a cross groove, a straight groove, a regular polyhedron, or the like, as shown in fig. 1 and 4, so as to fit a corresponding screwing tool.

In this embodiment, the first sliding engagement surface 304 may be configured as a circular arc surface, as shown in fig. 6, so as to rotate relative to the second sliding engagement surface 202 to achieve a rotating engagement. To improve the wear resistance of the first sliding engagement surface 304, in one embodiment, a bearing shell layer 312 is disposed on a side of the sliding member facing away from the base 305, and the first sliding engagement surface 304 is configured on the bearing shell layer 312, and the bearing shell layer 312 may be made of an existing bearing shell material, as shown in fig. 1 to 9. In a further scheme, a wear reduction material layer is further disposed on a side of the bearing bush layer 312 facing away from the sliding component, so as to improve the friction property of the bearing bush surface, and play a role in further reducing friction, so that the first sliding fit surface 304 is more wear-resistant, and the service life of the bearing is more favorably prolonged.

Since the sliding component 311 is movably disposed on the base 305, in order to prevent the sliding component 311 from self-swinging, moving and other problems, the sliding block assembly 300 further includes a locking mechanism, the locking mechanism includes a locking component 319, the locking component 319 is movably constrained on the base 305, the locking component 319 is mainly used for transversely pressing the sliding component 311 from the side of the sliding component 311, such as pressing the sliding component 311 against the base 305, so as to lock the sliding component 311 in a pressing manner, and prevent the sliding component 311 from moving relative to the base 305, as shown in fig. 5, the locking component 319 is also used for disengaging the sliding component 311 under the action of external force, so as to unlock the sliding component 311, so that the sliding component 311 can move along the height direction 303 of the base 305 under the driving of the height adjusting mechanism. Specifically, the locking component 319 which moves transversely can be used to cooperate with the sliding component 311, when the locking component 319 moves in the direction close to the sliding component 311, the locking component 319 can contact and transversely press the side surface of the sliding component 311, so that the sliding component 311 can be pressed in the direction perpendicular to the lifting direction of the sliding component 311, for example, the sliding component 311 can be pressed on the side wall of the guide cavity 307 in the base 305, as shown in fig. 5, the purpose of locking the sliding component 311 is achieved, the sliding component 311 which is adjusted in place is prevented from self-acting, and the bearing can be ensured to operate stably with high precision and long service life; when the position of the sliding component 311 needs to be adjusted, the locking component 319 only needs to be driven to move in the direction away from the sliding component 311, so that the purpose of unlocking the sliding component 311 can be achieved by separating the locking component 319 from the sliding component 311, then the position of the sliding component 311 can be adjusted in the height direction by using the height adjusting mechanism, and after the sliding component 311 is adjusted in place, the locking component 319 is used for locking the sliding component 311, which is very convenient and reliable.

In order to make the locking component 319 can transversely press the sliding component 311 from the side, in a more sophisticated scheme, the side wall of the base 305 is configured with a communication hole 310, the communication hole 310 can be communicated with the guide cavity 307, as shown in fig. 1 and 5, the locking component 319 can be transversely arranged on the communication hole 310, the communication hole 310 can play a role of guiding for the transverse movement of the locking component 319, so that the front end of the locking component 319 can correspond to the side wall of the sliding component 311, as shown in fig. 5, the rear end of the locking component 319 extends out of the base 305 through the communication hole 310, so that the staff can adjust the locking component 319 to lock/unlock the sliding component 311 from the outside of the base 305.

In order to enable the locking element 319 to be pressed continuously against the sliding element 311 when the sliding element 311 is locked, in the first embodiment, an internal thread is formed in the communication hole 310, i.e. the communication hole 310 is a threaded hole 309, and the locking element 319 is formed with at least one external thread 320 adapted to the internal thread; to form the threaded hole 309, the locking member 319 is configured with at least one length of threaded rod, by way of example, as shown in fig. 5, the locking member 319 may preferably be a locking bolt. The locking component 319 is screwed in the communication hole 310, as shown in fig. 5, the locking component 319 can be driven to move transversely relative to the sliding component 311 by rotating the locking component 319, so as to press the sliding component 311 or unlock the sliding component 311 transversely, not only can the distance between the locking component 319 and the sliding component 311 be adjusted, but also due to the threaded fit between the locking component 319 and the communication hole 310, the locking component 319 cannot rotate automatically under the action of external force easily, and thus the locking component 319 can press the sliding component 311 continuously and stably.

In such an embodiment, in order to facilitate the operator to actuate the locking member 319 to unlock or lock, in a more sophisticated version, the rear end of the locking member 319 is configured with an actuation portion such that the operator can rotate the locking member 319 via the actuation portion, which may be configured to fit the turning head 318 of a turning tool, for example, to rotate the locking member 319 with the corresponding turning tool. As mentioned above, in practice, the turning head 318 may be an inner hexagon, a cross groove, a straight groove or a regular polyhedron, as shown in fig. 1 and fig. 5, which will not be described herein again.

In the second embodiment, the locking mechanism further includes an elastic member 322, and the elastic member 322 is disposed between the locking member 319 and the base 305, as shown in fig. 8, so that the locking member 319 can press the side surface of the sliding member 311 under the elastic force of the elastic member 322, thereby achieving the purpose of locking the sliding member 311; when the locking member 319 moves in a direction away from the sliding member 311, the elastic potential energy of the elastic member 322 increases, that is, in this embodiment, the locking member 319 can continuously press the sliding member 311 under the elastic force of the elastic member 322, thereby achieving the purpose of continuously locking the sliding member 311. It can be understood that, at this time, no internal thread needs to be provided in the communication hole 310, and the communication hole 310 and the locking component 319 can form a clearance fit, so that the locking component 319 can move relative to the communication hole 310, and the communication hole 310 can guide the movement of the locking component 319. In practice, the elastic member 322 may be a compression spring, an extension spring, or the like. In order to facilitate installation of the elastic member 322, in a further embodiment, the sidewall of the locking member 319 is configured with a protrusion 321, the shape of the protrusion 321 may be determined according to actual requirements, for example, the protrusion 321 may be a ring structure, as shown in fig. 8, the elastic member 322 may be sleeved on the locking member 319, and both ends of the elastic member 322 are respectively limited and constrained on the base 305 and the protrusion 321, as shown in fig. 8, so that the elastic member 322 may generate a transverse elastic force, and the transverse elastic force acts on the locking member 319, so as to drive the locking member 319 to transversely press the side surface of the sliding member 311. In this embodiment, the rear end of the locking component 319 is configured with a driving portion, and the operator can conveniently pull the locking component 319 outwards through the driving portion to achieve the purpose of unlocking; at this time, the driving portion has various embodiments, for example, the driving portion may be a handle 324 configured at the rear end of the locking component 319, as shown in fig. 8, the shape of the handle 324 may be determined according to actual requirements, so as to be held by a worker, or the driving portion may be a hole or a notch or the like configured at the rear end of the locking component 319, so as to be connected with a special tool, so that the worker can pull the locking component 319 outwards by the special tool to unlock the locking component.

It can be understood that the above two embodiments can be implemented separately or simultaneously, for example, the protrusion 321 can be configured on the locking component 319 of the first embodiment, and the elastic component 322 is sleeved on the locking component 319, and two ends of the elastic component 322 are respectively limited and constrained on the base 305 and the protrusion 321, so that after the locking component 319 presses the locking component 319, the elastic component 322 also has elastic potential energy, thereby effectively preventing the locking component 319 from rotating and unlocking, and making the whole locking mechanism more reliable.

In order to achieve a better locking effect, in a further aspect, the locking mechanism further includes an elastic component 323, and the elastic component 323 may be fixed at the front end of the locking component 319 and/or the side surface of the sliding component 311, so that the locking component 319 may press the side surface of the sliding component 311 through the elastic component 323, as shown in fig. 9, that is, the acting force of the locking component 319 pressing the sliding component 311 is transmitted to the sliding component 311 through the elastic component 323, and the elastic component 323 is driven to elastically deform, so that the friction force between the front end of the locking component 319 and the side surface of the sliding component 311 may be increased, and the sliding component 311 may be more firmly pressed. In practice, the elastic member 323 may be a rubber contact fixed to the tip of the locking member 319, or may be a rubber layer fixed to the side surface of the sliding member 311 as shown in fig. 9, but the elastic member 323 may be made of other conventional elastic materials, and the same effect can be achieved.
