Example 1

The present embodiment provides a slider assembly comprising a base 305, a sliding member 311, and a height adjustment mechanism, wherein,

in this embodiment, the base 305 may support, limit and constrain the sliding component 311, and the shape of the base 305 may be determined according to actual requirements, and as shown in fig. 1 and 8, the base 305 may preferably adopt a square 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 and fig. 2, 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 is disposed between the inner ring 200 and the outer ring 100 of the bearing, the first sliding engagement surface 304 can be just configured to the second sliding engagement surface 202 of 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, that is, 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 of the base 305 through the height adjusting mechanism to change the height of the whole slider assembly, 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, and effectively solving the problem that the height of the existing bearing bush is not changed. Specifically, after the slider assembly is mounted between the bearing outer ring 100 and the bearing inner ring 200, in the using process of the bearing, 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, so that the gap between the first sliding fit surface 304 and the second sliding fit surface 202 can be adjusted, and by adopting the design, on one hand, the problem that the size of the bearing gap cannot meet the optimal design requirement due to errors in the production and assembly processes of the bearing can be effectively solved; on the other hand, the staff can regularly or after discovering that the first sliding fit face 304 has wearing and tearing, the clearance increases, adjust the clearance size between first sliding fit face 304 and the second sliding fit face 202 through adjusting the slider subassembly, make the big clearance between first sliding fit face 304 and the second sliding fit face 202 reach the best design requirement once more, make the bearing can continue to operate with best running state, so circulation, can effectively solve the bearing because of the too big wearing and tearing aggravation that appears in clearance, the operation is unstable, damage scheduling problem, ensure that the bearing can high accuracy, long-life, stable operation, make the bearing that is provided with this slider subassembly can effectively satisfy the demand that wind power generation system is longer life, and can effectively prevent to appear dismantling the problem of maintenance and change midway.

In order to enable the sliding component 311 to move strictly along the height direction 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 on the base 305 and extending through the upper end of the base 305, as shown in fig. 1-6, at least the lower end of the sliding member 311 is movably restricted 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 be vertically raised/lowered under the restriction and guide 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 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 functions as a transmission mechanism, 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.

When the bearing is used as a main bearing of a wind power generation system, the load carried by the sliding part 311 is very large, and the conventional height adjusting mechanism is difficult to meet the requirement, so in another preferred embodiment, the height adjusting mechanism comprises a jacking part 315, as shown in fig. 1-6, the jacking part 315 is movably arranged below the sliding part 311 and is in transmission fit with the sliding part 311, and the jacking part 315 is mainly used for supporting the sliding part 311 and jacking the sliding part 311 upwards along the height direction of the base 305. Specifically, the lifting member 315 can lift the sliding member 311 upwards along the height direction of the base 305, so as to adjust the height of the sliding member 311. And after the jacking component 315 adjusts the height of the sliding component 311 in a jacking mode, 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 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 enable the jacking component 315 to strictly perform linear movement under the action of external force, in a more sophisticated scheme, the jacking component 315 further includes a second constraint portion, and the jacking component 315 may be configured to be adapted to the second constraint portion, so in an embodiment, the jacking component 315 and the second constraint portion may form a moving pair along the height direction of the base 305, for example, the jacking component 315 may be an adjusting screw, the second constraint portion may be a threaded hole 309 adapted to the adjusting screw, the adjusting screw may be connected to the threaded hole 309 through a thread, the threaded hole 309 may be configured at the bottom of the base 305, and the adjusting screw may be assembled below the sliding component 311, an upper end of the adjusting screw abuts against a bottom end of the sliding component 311, and a 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 portion may form a moving pair perpendicular to the height direction of the base 305, that is, the lifting member 315 may move laterally under the constraint and guide of the second constraint portion, so as to lift the sliding member 311 laterally. 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. 2-6, 9 and 10, 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; and along the height direction 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. 2-6, 9 and 10, at this time, the second wedge-face 313 can just abut against the first wedge-face 316, when the height is adjusted, the sliding component 311 can be driven to ascend only by driving the jacking component 315 to move along the direction vertical to the height of the base 305 (i.e. transverse), thereby achieving the purpose of jacking the sliding component 311, moreover, the jacking part 315 and the sliding part 311 can realize the surface-surface contact transmission through the first wedge-shaped surface 316 and the second wedge-shaped surface 313, the power can be transmitted through the matching of the second wedge-shaped surface 313 and the first wedge-shaped surface 316, the bearing performance of the sliding component 311 and the sliding block assembly can be obviously improved, so that the sliding block assembly can be competent as a main bearing in a wind power generation system. In this embodiment, the second constraining portion may also have various embodiments, for example, the second constraining portion may be a transverse groove 308 formed in the base 305, as shown in fig. 5 and 7, the transverse groove 308 is perpendicular to the height direction of the base 305, and the lifting member 315 is configured to fit 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. In addition, 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 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 separately from the base 305, or can be configured on the base 305 in communication with each other, for example, when the first constraining portion is 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 be configured as 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 respectively 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 restricted in the transverse slot 308, as shown in fig. 5 and 6, so that the jacking member 315 can move transversely under the supporting action of the bottom of the guide cavity 307 and the restriction action of the transverse slot 308; the lower end of the sliding component 311 is positioned 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.

In order to adjust the height of the sliding block assembly, in a more sophisticated scheme, the height adjusting mechanism further includes an adjusting member 317 and a threaded hole 309 configured on the base 305, as shown in fig. 1, 5, 8 and 9, the adjusting member 317 is configured with an external thread adapted to the threaded hole 309, such that the adjusting member 317 can be screwed into the threaded hole 309, two ends of the adjusting member 317 respectively extend out of the threaded hole 309, one end of the adjusting member 317 can abut against the jacking component 315 and can also be rotatably connected to the jacking component 315, and the other end of the adjusting member 317 is configured with a screwing head 318 adapted to a screwing tool.

When the adjusting member 317 abuts against the jacking component 315, as shown in fig. 5 and 9, 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 component 315 is driven to move linearly along the second restriction portion, so that the sliding component 311 can be driven to ascend along the height direction of the base 305, and the height of the sliding block assembly 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 screwing tool, so that the adjusting member 317 can be driven to move linearly relative to the threaded hole 309, and the jacking component 315 is driven to move linearly along the second constraining portion, so that the sliding component 311 can be driven to lift/fall along the height direction of the base 305, and the height of the sliding block assembly can be effectively adjusted.

In practice, the turning head 318 may be a hexagon socket, a cross-shaped groove, a straight groove, a polyhedron, or the like, as shown in fig. 1, so as to be adapted to a corresponding turning tool.

In this embodiment, the first sliding engagement surface 304 may be configured as a circular arc surface 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 10. In a further aspect, a wear-reducing material layer is further disposed on a side of the bearing bush layer 312 facing away from the sliding component to improve the friction property of the surface of the bearing bush, so as to further reduce friction, so that the first sliding fit surface 304 is more wear-resistant, and is more beneficial to prolonging the service life of the bearing.
