Based on the embodiment of the present invention, all other embodiments obtained by the person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

The present embodiment provides a slider assembly suitable for a sliding bearing, comprising a base 400, a jacking member 600, and a sliding member 500, wherein,

the base 400 can support, limit and restrain the sliding component 500, the shape of the base 400 can be determined according to actual requirements, and preferably, as shown in fig. 1 and 12, the base 400 can preferably adopt a square-block-shaped structure. In practice, the base 400 is typically attached to the inner race 200 of the bearing or the outer race 100 of the bearing. To facilitate the detachable connection, the base 400 is generally configured with a mounting portion, for example, the mounting portion may include at least two mounting holes 401, as shown in fig. 1 and 12, and accordingly, the bearing inner ring 200 or the outer ring 100 is configured with holes that are adapted to the mounting holes 401, so that the base 400 may be detachably connected to the inner ring 200 or the outer ring 100 using fasteners (e.g., bolts, screws, etc.).

As shown in fig. 5, 10, 14, and 20, the slide member 500 is movably constrained to the base 400, and forms a pair of movement along the height direction of the base 400 together with the base 400, that is, the slide member 500 can be raised/lowered in the height direction with respect to the base 400. When the present slider assembly 300 is provided with the bearing inner ring 200 or the outer ring 100, the sliding component 500 is mainly used for contacting and/or supporting the corresponding inner ring 200 or outer ring 100, therefore, in this embodiment, the upper end of the sliding component 500 may be configured with a first sliding mating surface 502, and the first sliding mating surface 502 should be located above the base 400. So as to cooperate with the second sliding engagement surface 202 configured on the bearing inner ring 200 or the outer ring 100, in one aspect, the first sliding engagement surface 502 and the second sliding engagement surface 202 can rotate relatively so as to support and rotationally engage with each other; on the other hand, the first sliding engagement surface 502 and the second sliding engagement surface 202 may form a desired gap therebetween so as to form an oil film in the gap, thereby facilitating reduction of wear. Since the first sliding engagement surface 502 and the second sliding engagement surface 202 can rotate relatively, in practice, the first sliding engagement surface 502 is preferably configured to fit the arc surface of the second sliding engagement surface 202, as shown in fig. 1 and 5, and the shape of the sliding member 500 depends on practical requirements, for example, the sliding member 500 may preferably adopt a block structure, as shown in fig. 2, 7, 12 and 16, so as to be supported.

In this embodiment, the lifting member 600 may form a moving pair perpendicular to the height direction of the base 400 with the base 400 so as to move laterally, and the lifting member 600 is disposed below the sliding member 500, as shown in fig. 5.

In order to enable the sliding member 500 to move strictly along the height direction of the base 400 under the driving of the jacking member 600, the base 400 is further configured with a first restriction portion, and at this time, the sliding member 500 is configured to be adapted to the first restriction portion, so that the sliding member 500 and the first restriction portion can form a moving pair along the height direction of the base 400, that is, the first restriction portion not only can play a role of limiting and restricting the sliding member 500, but also can play a role of guiding the movement of the sliding member 500. The first restriction portion has various embodiments, for example, the first restriction portion may be a guide cavity 402 configured at the base 400 and penetrating the upper end of the base 400, as shown in fig. 5 and 6, at least the lower end of the sliding member 500 is movably restricted in the guide cavity 402, and the side wall of the sliding member 500 may be configured to fit the side wall of the guide cavity 402, so that the sliding member 500 can be vertically raised/lowered by the restriction and guide of the guide cavity 402. As another example, the first restriction portion may also be a guide bar provided to the base 400 in the height direction of the base 400 (i.e., the height direction of the base 400), and accordingly, the slide member 500 is configured with a guide hole to be fitted to the guide bar so that the slide member 500 can be raised/lowered under the guide of the guide bar. For another example, the first constraining portion may also be a groove 504 configured on the base 400, a side wall of the groove 504 is configured with a guiding groove distributed along the height direction, and a side of the sliding member 500 is limited and constrained by the guiding groove, so that the sliding member 500 can ascend/descend under the constraint of the guiding groove.

To improve wear resistance, in one embodiment, the sliding member 500 may be made of a sliding bearing material, such as bearing alloy (also called babbitt or white alloy), wear-resistant cast iron, copper-based and aluminum-based alloy, powder metallurgy material, plastic, rubber, hardwood and carbon-graphite, polytetrafluoroethylene (teflon, PTFE), modified Polyoxymethylene (POM), and the like. In yet another embodiment, the sliding member 500 is provided with a bearing shell layer 501 at the upper end, and the first sliding engagement surface 502 may be configured on the upper surface of the bearing shell layer 501, as shown in fig. 1-6, and the bearing shell layer 501 may be made of an existing bearing shell material. In a further aspect, a wear-reducing material layer is further disposed on a side of the bearing bush layer 501 facing away from the sliding component 500, 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 502 is more wear-resistant, and is more beneficial to prolonging the service life of the bearing.

As shown in fig. 2 to 6, the jacking member 600 is in driving fit with the sliding member 500 so as to adjust the position of the sliding member 500 by using the jacking member 600. To facilitate the transmission and matching with the jacking component 600, the sliding component 500 is configured with a first wedge surface 503 (or called an inclined surface, which refers to a surface inclined to the horizontal direction and the vertical direction during operation and is not described in detail later), as shown in fig. 2-3, the first wedge surface 503 is located below the first sliding matching surface 502 (i.e., below along the height direction of the sliding component 500, such as directly below, or laterally below, etc.), and the first wedge surface 503 faces the lower end of the sliding component 500, i.e., the first wedge surface 503 is configured at a position away from the first sliding matching surface 502, as shown in fig. 2 and 3. Correspondingly, the jacking member 600 is configured with a second wedge-face 601 fitting the first wedge-face 503, as shown in fig. 4-6, the second wedge-face 601 facing the upper end of the sliding member 500. The base 400 is further configured with a second restriction portion, and the jacking member 600 is configured to be fitted to the second restriction portion, so that the jacking member 600 can be movably restricted to the base 400 by the second restriction portion and can be moved laterally (i.e., a direction perpendicular to the height direction of the base 400) with respect to the base 400. As shown in fig. 5 and 6, the jacking member 600 is disposed below the sliding member 500, such that the second wedge-shaped surface 601 can be drivingly engaged with (e.g., contact and abut against) the first wedge-shaped surface 503, such that the jacking member 600 can lift the sliding member 500 upward through engagement of the second wedge-shaped surface 601 with the first wedge-shaped surface 503. Specifically, when the sliding block assembly 300 is used, only the jacking component 600 needs to be driven to move transversely, the jacking force along the height direction can be applied to the first wedge-shaped surface 503 through the second wedge-shaped surface 601, the sliding component 500 is driven to ascend, the purpose of jacking the sliding component 500 can be achieved, the jacking component 600 and the sliding component 500 can achieve surface-surface contact transmission through the first wedge-shaped surface 503 and the second wedge-shaped surface 601, power is transmitted through the matching of the second wedge-shaped surface 601 and the first wedge-shaped surface 503, the bearing performance of the sliding component 500 and the sliding block assembly 300 can be remarkably improved, and the sliding block assembly 300 can be competent as a main bearing in a wind power generation system. It is understood that the second restriction portion has various embodiments, for example, the second restriction portion may be a transverse groove 403 formed on the base 400, the transverse groove 403 is perpendicular to the height direction of the base 400, as shown in fig. 5, and the jacking member 600 is configured to fit the transverse groove 403 and form a sliding pair with the transverse groove 403. For another example, the second constraining portion may also be a transverse channel configured on the base 400, and the lifting member 600 is configured to fit the transverse channel and form a moving pair with the transverse channel, so that the transverse slot 403 can constrain and guide the lifting member 600, and the same effect can be achieved. It can be understood that, since the first restriction portion and the second restriction portion can be configured on the base 400, in practice, the second restriction portion and the first restriction portion can be configured on the base 400 separately, or can be configured on the base 400 in communication with each other, for example, when the first restriction portion is the guide cavity 402, the bottom surface of the guide cavity 402 and two side surfaces parallel to each other on two sides of the bottom surface can be configured as the second restriction portion, as shown in fig. 5, and the three can just form the transverse slot 403 for restricting the jacking member 600, at this time, the side wall and the bottom surface of the jacking member 600 can be configured to be adapted to the second restriction portion, for example, the jacking member 600 can preferentially adopt a wedge-shaped block, as shown in fig. 4, that is, in this embodiment, the sliding member 500 can form a moving pair in the height direction with the guide cavity 402, and the jacking member 600 can form a moving pair in the transverse direction with the guide cavity 402, and the jacking member 600 is located below the sliding member 500 so as to achieve the purpose of jacking up the sliding member 500 by using the lateral movement of the jacking member 600.

In a more complete scheme, the device further includes an adjusting member 602 and a threaded hole 404 configured in the base 400, as shown in fig. 1 and fig. 4 to fig. 6, the adjusting member 602 is configured with an external thread adapted to the threaded hole 404, so that the adjusting member 602 can be screwed into the threaded hole 404, two ends of the adjusting member 602 respectively extend out of the threaded hole 404, one end of the adjusting member 602 can abut against the jacking component 600 and can also be rotatably connected to the jacking component 600, and the other end is configured with a screwing head 603 adapted to a screwing tool. When the adjusting member 602 abuts against the jacking member 600, as shown in fig. 4 and 5, the jacking member 600 can be driven to move only in one direction; specifically, the staff rotates the adjusting part 602 through twisting the instrument, can drive the adjusting part 602 for screw hole 404 rectilinear movement to drive jacking part 600 along the restricted portion rectilinear movement of second, thereby can drive sliding part 500 along the direction of height of base 400 rise, and then effectively adjust the position of sliding block assembly 300. When the adjusting piece 602 is rotatably connected to the jacking component 600, the jacking component 600 can be driven to move bidirectionally; specifically, the worker can rotate the adjusting member 602 by the twisting tool, so that the adjusting member 602 can be driven to move linearly relative to the threaded hole 404, and the lifting member 600 is driven to move linearly along the second restriction portion, so that the sliding member 500 can be driven to move up/down along the height direction of the base 400. In practice, the turning head 603 may adopt an inner hexagon, a cross-shaped groove 504, a straight groove 504, a regular polyhedron or the like, as shown in fig. 1 and 4, so as to adapt to a corresponding turning tool.

Since the second wedge-shaped surface 601 is in driving fit with the first wedge-shaped surface 503, but in the implementation, the position and the number of the first wedge-shaped surface 503 can be varied, and at this time, the second wedge-shaped surface 601 can be adapted correspondingly, for example, the entire lower end surface of the sliding member 500 can be configured as the first wedge-shaped surface 503, as shown in fig. 7, and correspondingly, the second wedge-shaped surface 601 configured on the jacking member 600 is configured to be adapted to the first wedge-shaped surface 503, and at this time, the second constraint part is configured on the base 400, and the bottom surface and both sides of the jacking member 600 can be preferentially configured to be adapted to the second constraint part so as to move transversely. In this embodiment, the first wedge surface 503 has a larger area so as to have a larger contact area with the jacking component 600, thereby contributing to an increase in load-bearing capacity.

In practice, the number of the bosses 505 may be one, for example, the lower end of the sliding member 500 is configured with one boss 505, and the boss 505 may be preferentially configured at the middle position of the lower end of the sliding member 500, as shown in fig. 8 to 10. The number of the bosses 505 may also be two, and at this time, to simplify the structure, the two bosses 505 may be respectively and symmetrically configured on the sliding member 500, and correspondingly, the jacking member 600 is configured with two second wedge-shaped surfaces 601 respectively adapted to the first wedge-shaped surfaces 503, which is beneficial to improving the stress, so that the load applied to the sliding member 500 is more uniformly distributed, and the bearing capacity of the sliding member 500 can be significantly improved.

Of course, the lower end of the sliding member 500 may be configured with a plurality of bosses 505, and the jacking member 600 may be configured to fit each boss 505, which is not illustrated here.

Example 3

Since the position of the sliding component 500 is adjustable, in order to make the sliding component 500 adjusted in place stably and durably maintain at the set position, in a more sophisticated scheme, the sliding block assembly 300 provided in this embodiment further includes a locking component 700, and accordingly, the base 400 is configured with a limiting portion 405 for restricting the locking component 700, and meanwhile, the sliding component 500 is configured with a limiting structure for locking (locking) and/or unlocking in cooperation with the locking component 700, so that in the actual use process, after the sliding component 500 is adjusted in place, the sliding component 500 can be locked in cooperation with the locking component 700 through the limiting structure, and the sliding component 500 is prevented from self-acting. When the position of the sliding member 500 needs to be adjusted, the sliding member 500 can be unlocked through the cooperation of the limiting structure and the locking member 700, so that the position of the sliding member 500 can be adjusted.

In practice, the position-limiting structure has various embodiments according to different locking members 700, for example, when the locking member 700 is an elastic member, as shown in fig. 5 and 6, in this case, the position-limiting portion 405 may be a stopper configured at the opening of the guide cavity 402, and the position-limiting structure may be a step 506 adapted to the elastic member, and the step 506 is configured at a position corresponding to the stopper, so that the elastic member may be assembled between the position-limiting structure and the position-limiting portion 405 to provide a downward pressing force to the sliding member 500 along the height direction of the slider assembly 300, and under the pressing force, the sliding member 500 may press the lower jacking member 600 to lock the sliding member 500 and prevent the sliding member 500 from being separated from the jacking member 600.

The elastic component has various structures, for example, the elastic component can adopt a compression spring; as another example, the resilient member may take the form of a spring leaf in compression. For another example, the elastic member may be an elastic material layer (or referred to as an elastic material plate), and the elastic material layer may be made of an elastic material, such as rubber, for example, so as to have elasticity.

It is understood that the limiting structure may be configured on only one side of the sliding part 500, or may be configured on two sides (as shown in fig. 5 and 6), three sides, four sides, etc. of the sliding part 500, which are not illustrated herein.

Example 4

The main difference between this embodiment 4 and the above embodiment 3 is that in the slider assembly 300 provided in this embodiment, the structures of the locking component 700 and the limiting structure are different, specifically, in this embodiment, the slider assembly 300 further includes a transmission member 703 and a threaded hole 404 formed in the base 400, the transmission member 703 is configured with an external thread adapted to the threaded hole 404, so that the transmission member 703 can be screwed to the threaded hole 404, as shown in fig. 11, 14 and 15, and two ends of the transmission member 703 extend out of the threaded hole 404, respectively, one end of the transmission member 703 is rotatably connected to the locking component 700, as shown in fig. 14, the other end of the transmission member 703 is configured with a screwing head 603 adapted to a screwing tool, as shown in fig. 14, so that the transmission member 703 can drive the locking component 700 to move transversely, that is, the moving direction of the driving member 703 is perpendicular to the height direction of the base 400 so as to lock or unlock the sliding member 500 using the lateral movement of the locking member 700. At this time, the locking member 700 is configured with a third wedge surface 701, and the third wedge surface 701 faces the lower end of the sliding member 500, and accordingly, the limiting structure is adapted to a fourth wedge surface 509 of the third wedge surface 701, and the fourth wedge surface 509 faces the upper end of the sliding member 500, as shown in fig. 12-15, when the locking member 700 moves laterally in a direction away from the sliding member 500, the third wedge surface 701 and the fourth wedge surface 509 are separated from each other, so as to achieve the purpose of unlocking; when the locking member 700 moves laterally in a direction close to the sliding member 500, the third wedge surface 701 may contact and form a fit with the fourth wedge surface 509, so that the fourth wedge surface 509 may be limited and constrained by the third wedge surface 701, and the purpose of limiting and constraining the sliding member 500 by the locking member 700 is achieved.

In practice, the sliding member 500 may be configured with a fourth wedge surface 509 to cooperate with a third wedge surface 701 configured with the locking member 700; it is also possible to configure two fourth wedge-shaped surfaces 509 to match with the two third wedge-shaped surfaces 701 configured on the locking component 700, for example, as shown in fig. 12 to 15, the sliding component 500 includes two fourth wedge-shaped surfaces 509, and the two fourth wedge-shaped surfaces 509 are respectively configured on two sides of the first sliding mating surface 502 so as to limit and restrain the sliding component 500 from two sides of the first sliding mating surface 502, thereby facilitating a better locking/unlocking function.

In order to allow the locking member 700 to move strictly laterally, in one embodiment, the upper end of the locking member 700 can be constrained to the limiting portion 405 formed on the base 400, as shown in fig. 6 and 15; and both sides of the locking member 700 may be limitedly restricted to the sidewalls of the guide cavity 402 as shown in the figure, so as to restrict the locking member 700 using the limiting portions 405, the sidewalls of the guide cavity 402, and guide the movement of the locking member 700.

In another embodiment, the lower end of the sliding member 500 is configured with a strip-shaped groove 507, two side walls of the strip-shaped groove 507 are respectively and symmetrically configured with a limiting groove 508, the limiting groove 508 is communicated with the strip-shaped groove 507, as shown in fig. 16-20, the limiting groove 508 is respectively configured with a fourth wedge surface 509, as shown in fig. 16, for example, the side wall of the limiting groove 508 near the lower end of the sliding member 500 may be configured as the fourth wedge surface 509. Accordingly, at least the upper end of the locking means 700 is configured to fit into the strip-shaped groove 507, and both sides of the locking means 700 are configured with third wedge faces 701 respectively, which fit into the fourth wedge faces 509, as shown in fig. 18 and 19. Meanwhile, the base 400 (e.g., the bottom of the guide cavity 402) is configured with a constraining groove 407, the constraining groove 407 is located right below the strip-shaped groove 507, and the constraining groove 407 is transversely arranged, as shown in fig. 19 and 20. The lower end of the locking member 700 is configured to fit into the constraining block 702 of the constraining groove 407 and is constrained in the constraining groove 407 in a limiting manner, as shown in fig. 19 and 20, so that the locking member 700 and the constraining groove 407 can form a lateral moving pair, and in actual use, the constraining groove 407 guides the locking member 700 so that the locking member 700 can move along the constraining groove 407 but cannot be disengaged from the constraining groove 407, and the fourth wedge surface 509 and the third wedge surface 701 can be driven to contact with or separate from each other by the lateral movement, thereby achieving the purpose of locking/unlocking the sliding member 500.
