Roller bearing and roller chain mounted with roller bearing

Abstract

A roller chain equipped with roller bearings, in which a plurality of rollers are arranged between a roller as an outer ring and a bush as an inner ring, including a substantially Ring cage. The cage includes a plurality of pockets for guiding at least a portion of each of the rollers inside the cage.

Description

technical field [0001] The invention relates to a roller bearing and a roller chain equipped with the roller bearing. Background technique [0002] Generally, Japanese Unexamined Patent Application, First Publication No. Sho 62-4112 (Japanese Examined Patent Application, Second Publication No. Japanese Laid-open No. Hei 4-78523) discloses a roller bearing equipped with a roller bearing. child chain. Fig. 22 is a sectional view of the roller chain disclosed in the above-mentioned Japanese Unexamined Patent Application First Publication No. Sho 62-4112. In the roller chain 1 shown in Figure 22, a plurality of rollers 4 for bearings are provided on the outer circumference of the bushing 3, and the two ends of the bushing are connected with a pair of inner connecting plates 2, and the rollers 5 and The rollers 4 are attached to surround the rollers 4, and a thrust bearing receiving plate 6 is inserted into the space between the rollers 5 and the inner connecting plate 2.

AI Technical Summary

Problems solved by technology

Therefore, abrasion occurs so that the smooth rotation of the roller 5 is suppressed

[0007] (2) The contact between the rollers 4 will cause collision noise, and repeated collisions will cause fatigue fracture

[0010] (5) Since the inner side of the collar 5a is difficult to arrange to enhance the surface roughness, and it is difficult to perform heat treatment in the manufacturing process, the production efficiency of the roller 5 is low

Thus, there must be many different types of cages, and the management of these parts is not easy and expensive
