[0019] The present utility model will be further described below in conjunction with the drawings and specific embodiments.

[0020] Example 1

[0021] As Figure 1 、 Figure 2 、 Figure 3 shown, in this example, a special bearing for a hydraulic machine includes a seat body 1 and a connector 2 at the bottom end of its circumferential surface. The seat body 1 is in a ring shape, and the connector 2 forms a threaded surface at the bottom end, such as an internal thread or an external thread type, etc. An outer ring 5 is fitted and fixed in the ring opening of the seat body 1, an inner ring 7 is arranged in the ring opening of the outer ring 5, and balls 6 are arranged between the inner ring 7 and the outer ring 5 to form a bearing.

[0022] Brackets 3 are fixed on both side end faces of the seat body 1. Guide rods 8 are connected in a guiding and sliding manner at the end of the bracket 3 facing the balls 6. There are two guide rods 8 arranged side by side, and the ends of the two guide rods 8 facing the seat body are fixed to a mounting plate 11.

[0023] An elastic member 12 is arranged between the bottom surface of the mounting plate 11 and the corresponding bracket end face to form an elastic connection. The elastic member is such as a spring. A lubricating member 10, such as a block formed of graphite, is fixed on the mounting plate 11. Under the action of the spring, the lubricating member is kept in contact with the corresponding balls, etc., and the lubricating member lubricates the balls, etc. The above are all prior arts and will not be elaborated here.

[0024] In this example, the structure of the bracket is improved. For example, the bracket 3 includes a first frame body 31 and a second frame body 32. The longitudinal end of the L-shaped first frame body 31 is fixed to the side of the end face of the seat body 1, and the second frame body 32 is installed at the end of the transverse end of the first frame body 31. Specifically, a U-shaped groove is formed at the end of the strip-shaped second frame body 32, and clamping grooves 33 are formed on both side end faces at the end of the transverse end of the first frame body 31. When the first frame body 31 and the second frame body 32 are inserted, the two side walls of the U-shaped groove 35 are in the corresponding clamping grooves 33 and are in interference fit, and the clamping grooves are used for limiting.

[0025] In this example, a push block 9 is slidably connected to the end face of the second frame body 32. For example, a T-shaped sliding groove is formed on the end face, and the push block 9 is slidably connected with the T-shaped sliding groove. The push block is in a rectangular shape and is formed of a magnetic material. A convex block 14 protrudes from the bottom surface of the push block 9, and the bottom end face of the convex block 14 is in an inclined shape. A through hole is formed on the bottom wall of the sliding groove, and a locking column 13 is slidably connected at the through hole. The end face of the head of the locking column 13 is also in an inclined shape and fits with the inclined surface of the convex block 14. As the push block 9 moves back and forth, the convex block 14 presses the locking column to move down. The locking column 13 is also formed of a magnetic material and the locking column 13 and the push block 9 are magnetically attracted to each other. After the push block is reset, the locking column is reset under the magnetic attraction.

[0026] In this example, a locking hole 34 is formed on the bottom wall of the clamping groove 33. When the locking column 13 moves down, the end of the locking column is inserted into the locking hole to fix the first frame body and the second frame body. When unlocking, just push the slider.

[0027] Under this structure, unlocking or locking can be completed by moving the pushing block, which is convenient for disassembly and then replacing the lubricating part.

[0028] In this example, a fitting groove is formed on the top surface of the mounting plate 11, and the bottom of the lubricating part 10 is fitted and fixed in the fitting groove. For the guide rod, a guiding hole is formed at the end of the second frame body 32, and the end of the guide rod 8 passes through the guiding hole for guiding and sliding.

[0029] Preferably, heat dissipation grooves 4 are formed on the circumferential surface of the seat body 1 to improve the heat dissipation performance.

[0030] The above are only the preferred embodiments of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions falling within the idea of the present invention belong to the protection scope of the present invention. It should be pointed out that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements should also be regarded as the protection scope of the present invention.
