Problems solved by technology

For occasions with non-full circle rotation (similar to reciprocating swing), large impact, and small rotation angle, that is, when the bearing mainly plays a supporting role, a bearing that can reduce vibration and impact is required; and now Some bearings do not have the function of vibration reduction and shock reduction because their rolling elements are fully rigid structures.

Abstract

The invention discloses a vibration-reducing buffer bearing which comprises an outer ring, an inner ring and a plurality of rolling bodies arranged between the outer ring and the inner ring. The rolling bodies are made of a flexible material, the outer surface of the inner ring is provided with protruding portions protruding towards the inner surface of the outer ring, and the adjacent rolling bodies are separated by the protruding portions for independent operation. The vibration-reducing buffer bearing can achieve buffering and vibration reduction functions, and the service life of the bearing is prolonged, and the stability of the bearing is improved.

Description

technical field [0001] The invention relates to a bearing, in particular to a vibration-reducing and shock-reducing bearing. Background technique [0002] Bearing is an important part of modern mechanical equipment. Its main function is to support mechanical rotating parts, reduce the friction coefficient during its movement and keep the center of the shaft fixed. For occasions with non-full circle rotation (similar to reciprocating swing), large impact, and small rotation angle, that is, when the bearing mainly plays a supporting role, a bearing that can reduce vibration and impact is required; and now Some bearings do not have the function of vibration reduction and shock reduction because their rolling elements are fully rigid structures. Contents of the invention [0003] In view of this, the object of the present invention is to provide a vibration-reducing and shock-reducing bearing, so as to realize the function of buffering and reducing vibration, and improve the ...
