Embodiment Construction

[0008] Such as figure 1 As shown, the short cylindrical roller bearing in this embodiment includes an outer ring 1 , an inner ring 2 , a cage 3 and rollers 4 .

[0009] The width of the inner ring 2 is twice the width of the outer ring 1 , a part of the inner ring 2 is installed in the outer ring 1 , and another part of the inner ring 2 is outside the outer ring 1 . The cage 3 is arranged between the outer ring 1 and the inner ring 2. The cage 3 is a copper single retaining ring combination cage, which is composed of a cage seat 3-1 and a cage cover 3-2. On the cage 3-1 Several rollers 4 are installed, and the cage cover 3-2 is connected to the end face of the cage component seat 3-1 to limit the rollers 4. The circumferential surface of each roller 4 is in contact with the raceway surface of the outer ring 1 and the raceway surface of the inner ring 2 .

Abstract

The invention discloses a short columnar roller bearing; the outer ring component and the inner ring of the short columnar roller bearing can be flexibly moved. The short columnar roller bearing comprises an outer ring, an inner ring, a holding rack and a roller; the holding rack comprises a holding rack seat and a holding rack cover; the holding rack is arranged between the outer ring and the inner ring; a plurality of rollers are installed on the holding rack seat; the holding rack cover is connected with the end face of the holding rack seat to limit the rollers; the circumference of each roller is respectively and mutually contacted with the rolling faces of the outer ring and the inner ring; and the width of the inner ring is twice as that of the outer ring, wherein part of the inner ring is installed in the outer ring and other part of the inner ring is positioned outside the outer ring.

Description

technical field [0001] The invention relates to a bearing, in particular to a short cylindrical roller bearing. Background technique [0002] The short cylindrical roller bearing used in the automobile transmission mechanism requires that the outer ring assembly and the inner ring can be displaced relative to each other. However, the existing short cylindrical roller bearings do not meet the requirements of the automobile transmission mechanism due to the small movement range due to structural limitations. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a short cylindrical roller bearing, the outer ring assembly and the inner ring of the short cylindrical roller bearing can move relatively flexibly. [0004] The invention includes an outer ring, an inner ring, a cage and rollers; the cage is composed of a cage seat and a cage cover, the cage is arranged between the outer ring and the inner ring, and several roll...
