Detailed Description

For the purposes, technical solutions and advantages of the present application, the technical solutions of the present application will be clearly and completely described below with reference to specific embodiments of the present application and corresponding drawings. It will be apparent that the described embodiments are only some, but not all, of the embodiments of the present application. All other embodiments, which can be made by one of ordinary skill in the art without undue burden from the present disclosure, are within the scope of the present disclosure.

As shown in fig. 1 to 5, a jacquard bearing, comprising: an outer cover, an inner ring 3, a cage 5 and a plurality of rolling elements 6. The housing comprises a disc-shaped housing body 100 and a mounting cavity 13. The mounting chamber 13 extends axially through the housing body 100 along the housing body 100. The outer cover 100 includes a first cover portion 10 and a second cover portion 20 that can be mutually covered in the axial direction thereof. The inner ring 3 is rotatably arranged in the mounting cavity 13. The center axis of the inner ring 3 coincides with the center axis of the outer cover 100. The rolling elements 6 are disposed between the inner ring 3 and the outer cover 100. The rolling elements 6 are uniformly distributed on the outer circumference of the inner ring 3. The cage 5 is provided between the inner ring 3 and the outer cover 100, and controls the pitch between the rolling elements 6 in the circumferential direction of the inner ring 3. The cage 5 comprises a plurality of roller chambers for placing the rolling bodies 6, and the rolling bodies 6 are arranged in the roller chambers in a rolling way.

The first cover part 10 and the second cover part 20 have the same structure, but the mounting directions of the two parts are different, so that the two parts are symmetrical to each other along the mounting surface. The first cover body 10 and the second cover body 20 each include a cover body 11, and after the first cover body 10 and the second cover body 20 are mutually covered, a mounting cavity 13 is formed inside the cover body 11 of both.

Preferably, the first cover body 10 and the second cover body 20 are of an integrated structure, and the number of parts of the jacquard bearing can be effectively reduced by adopting the integrated structure, so that the assembly efficiency is improved.

Preferably, the first cover body 10 and the second cover body 20 are processed by adopting a stamping process, and the processing efficiency can be effectively improved by adopting the stamping process, so that the overall processing time of the jacquard bearing is shortened, and the production efficiency is fundamentally improved. Meanwhile, the production cost of the jacquard bearing can be reduced.

The mounting cavity 13 includes an inner ring receiving cavity 131 and a limiting circular hole 132. The inner ring accommodating chamber 131 is a cylindrical chamber. The center line of the inner ring receiving chamber 131 coincides with the center of the outer cover 100. The limiting round holes 132 are disposed at two ends of the inner ring accommodating cavity 131 and are communicated with the inner ring accommodating cavity 131, so that the mounting cavity 13 can penetrate through the outer cover body 100 along the axial direction of the outer cover body 100. The inner diameter of the limit round hole 132 is smaller than the inner diameter of the inner ring accommodating chamber 131. The limiting circular hole 132 can limit the inner ring 3, and prevent the inner ring 3 from moving along the axial direction of the housing body 100.
