Mute noise reduction type bearing

Abstract

The invention discloses a mute noise reduction type bearing, and belongs to the technical field of bearings. The mute noise reduction type bearing comprises a bearing outer ring, the inner wall of the bearing outer ring is provided with an outer buffer channel, a bearing inner ring is rotatably connected between the inner walls of the bearing outer ring, and the outer surface wall of the bearing inner ring is provided with an inner buffer channel; an outer annular groove is formed in the position, close to the edge of the top, of the inner wall of the bearing outer ring, and buffer blocks are slidably connected to the inner wall of the outer buffer channel and the inner wall of the inner buffer channel correspondingly. The mute noise reduction type bearing can solve the following problems in the prior art, when the rotating speed of a traditional bearing is higher or lubricating oil in a roller pass is polluted, hard friction is generated between the outer surface of a roller and the roller pass, noise is generated, noise pollution is generated to the surrounding environment, normal operation of equipment and normal work of workers are affected, and when a motor is in butt joint with the equipment through a bearing, a sliding phenomenon occurs at the joint due to aging and abrasion of the bearing, so that the motor and the equipment break down, and serious potential safety hazards are generated.

Description

technical field [0001] The invention relates to the technical field of bearings, in particular to a quiet and noise-reducing bearing. Background technique [0002] Bearings are an important part of contemporary mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. Commonly used bearings include sliding bearings, joint bearings and rolling bearings. Among them, the sliding bearing has no inner and outer rings and no rolling elements, and is generally made of wear-resistant materials. It is often used in low-speed, light-loaded and lubricating and maintenance-difficult mechanical rotating parts. The sliding contact surface of the joint bearing is a spherical surface, which is mainly suitable for swinging, tilting and rotating movements. Rolling bearings are divided into radial bearings and thrust bearings according to the load direction or nominal contact angl...

AI Technical Summary

Problems solved by technology

[0003] When using the bearing device, during the rotation of the traditional bearing, due to the roller sliding in the raceway, when the speed is fast or the lubricating oil in the raceway is polluted, hard friction will occur between the outer surface of the roller and the raceway, Make it emit noise, generate noise pollution to the surrounding environment, affect the normal operation of the equipment and the normal work of the workers, and when the motor is docked with the equipment through the bearing, due to the aging and wear of the bearing, the joint will slip, resulting in failure of the motor and equipment , resulting in serious safety hazards
