Description

Technical Field

[0001] The utility model relates to the technical field of bearings, in particular to a wear-resistant bearing body. Background Art

[0002] The turntable bearing body is a large and extra-large bearing body that can accept comprehensive loads and has a special structure. It has the characteristics of compact structure, sensitive rotation, and easy maintenance of the device. Where there is a bearing, there must be a support point. The internal support point of the bearing is the shaft, and the external support is what is commonly called the bearing body. According to the "A super wear-resistant and fatigue-resistant high-speed rolling turbocharger bearing body" provided by China Patent Authorization Announcement No. CN216842737U, the above document can avoid the movement of the first ball by setting a convex ring, and avoid the movement of the inner ring by setting the second ball. However, the overall design structure is relatively complicated. Since the use of the bearing requires rotation, it is easy to affect the overall stability. At the same time, although a convex ring is set on the side of the first ball, this design makes it difficult to ensure the spacing between the balls, which leads to different forces on the balls and affects the service life. Utility Model Content

[0003] In order to solve the above problems, that is, to solve the problems raised by the above background technology, the utility model proposes a wear-resistant bearing body, including an outer ring, an inner ring is arranged inside the outer ring, and a plurality of first balls are arranged for rolling between the outer ring and the inner ring. A mounting seat is provided on one side of the outer wall of the outer ring, and a mounting cover is provided on the closed end of the mounting seat. Limiting rings are provided on the inner sides of the mounting seat and the mounting cover corresponding to the first balls, and the two limiting rings are arranged in a close fit, and a slot corresponding to the first ball is opened between the two limiting rings, and the plurality of slots are equidistantly distributed.

[0004] Preferably, the mounting seat and the mounting cover are both provided with a plurality of grooves corresponding to the inner ring, and second balls are arranged in the grooves, and the second balls can press the inner ring tightly.

[0005] Preferably, the inner diameter of the inner ring is smaller than the inner diameters of the mounting seat and the mounting cover, so as to facilitate the connection between the inner ring and the shaft body.

[0006] Preferably, the mounting seat is provided with a mounting groove adapted to the mounting cover, and the mounting cover can be placed in the mounting groove and fixedly connected by bolts.

[0007] The beneficial technical effects of the present invention are as follows: the bearing body fixes the positions of several first balls by directly arranging a limiting ring on the mounting seat and the mounting cover, and arranging equidistant arc-shaped grooves on the limiting ring, thereby ensuring the spacing between the first balls and preventing the first balls from moving; by arranging the second balls in the groove, the balls can position the inner ring, while also ensuring the spacing between the second balls; the bearing body can directly arrange the bearing in the mounting seat and fix it with the mounting cover, thereby realizing a direct connection between the bearing and the mounting seat, reducing the overall size of the bearing body, and making the structure of the entire bearing body simpler and more stable, thereby improving the transmission efficiency and service life.

[0012] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0013] The utility model proposes a wear-resistant bearing body, comprising an outer ring 1, an inner ring 3 is arranged inside the outer ring 1, and a plurality of first balls 2 are arranged to roll between the outer ring 1 and the inner ring 3, a mounting seat 4 is arranged on one side of the outer wall of the outer ring 1, and a mounting cover 5 is arranged on the closed end of the mounting seat 4, and a limiting ring 6 is provided on the inner side of the mounting seat 4 and the mounting cover 5 corresponding to the first ball 2, the two limiting rings 6 are arranged in a close fit, and a groove 7 corresponding to the first ball 2 is opened between the two limiting rings 6, and the plurality of grooves 7 are equidistantly distributed. The bearing body fixes the positions of the plurality of first balls 2 by directly arranging the limiting ring 6 on the mounting seat 4 and the mounting cover 5, and arranging equidistant arc grooves 7 on the limiting ring 6, thereby ensuring the spacing between the first balls 2 and avoiding the first balls 2 from moving, and the structure is simpler and more efficient.

[0014] Specifically, the mounting seat 4 and the mounting cover 5 are both provided with a number of grooves 8 corresponding to the inner ring 3, and a second ball 9 is arranged in the groove 8. The second ball 9 can press the inner ring 3 tightly. By arranging the second ball 9 in the groove 8, the ball can position the inner ring 3, and the spacing between the second balls 9 is also guaranteed.

[0015] Specifically, the inner diameter of the inner ring 3 is smaller than the inner diameters of the mounting seat 4 and the mounting cover 5 , so as to facilitate the connection between the inner ring 3 and the shaft body.

[0016] Specifically, a mounting groove 10 adapted to the mounting cover 5 is provided on the mounting seat 4. The mounting cover 5 can be placed in the mounting groove 10 and fixedly connected by bolts. This design can fix the entire bearing body inside the mounting seat 4, thereby achieving the fixation of the entire bearing.

[0017] The bearing body fixes the positions of several first balls 2 by directly setting a limit ring 6 on the mounting seat 4 and the mounting cover 5, and setting equidistant arc grooves 7 on the limit ring 6, thereby ensuring the spacing between the first balls 2 and preventing the first balls 2 from moving. At the same time, by opening a groove 8 on the mounting seat 4 and the mounting cover 5, a second ball 9 is set inside, so that the ball can position the inner ring 3, and the spacing between the second balls 9 is also ensured. The bearing body can directly set the bearing in the mounting seat 4 and seal it through the mounting cover 5, thereby realizing a direct connection between the bearing and the mounting seat 4, reducing the overall size of the bearing body, so as to maximize the use of the internal space of the equipment.
