Wear-resistant one-way needle bearing

Abstract

The invention discloses a wear-resistant one-way needle bearing, and relates to the technical field of bearings. The wear-resistant one-way needle bearing comprises a bearing outer ring, a one-way inner ring and a retainer, wherein a first mounting position and a second mounting position are respectively arranged inside the bearing outer ring, the one-way inner ring is arranged at the first mounting position, and the retainer is arranged at the second mounting position. According to the wear-resistant one-way needle bearing, a brake arc groove, a limiting column, a spring groove, a spring, a buffer supporting pad, a one-way needle roller, a plurality of sets of mounting positions, the one-way inner ring and the retainer are arranged, so that the bearing has good stability and a good braking effect, and the one-way needle roller is not prone to being worn and is more durable.

Description

technical field [0001] The invention belongs to the technical field of bearings, in particular to a wear-resistant one-way needle roller bearing. Background technique [0002] One-way needle roller bearings, also known as needle roller clutches, are composed of stamped outer rings and plastic cages; the cages can be equipped with plastic reeds or stainless steel reeds to guide the needle rollers. The inclined raceway on the outer ring and the needle rollers serve as Locking device. It has grooves on the surface and is mainly aimed at diabolo manufacturing companies. It has also launched solid ferrule-type one-way needle roller bearings, mainly for fitness equipment companies, and has also developed ultra-thin one-way needle roller bearings, mainly for precision machinery companies. [0003] Most of the existing one-way needle roller bearings operate through a single cage, which is prone to slipping during operation, and when the bearing is running in the opposite direction,...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to provide a wear-resistant one-way needle roller bearing, which solves the problem that most of the existing one-way needle roller bearings operate through a single cage, which is prone to slipping during operation, and when the bearing reverses In the process of running in the direction, the wear of the needle roller is too large, the size of the needle roller is reduced after long-term use, the spring is deformed by the centripetal force for a long time, and the braking effect is reduced.
