Compressor device with noise reduction bearing and noise reduction holding rack production method

Abstract

The invention discloses a compressor device with a noise reduction bearing. The compressor device comprises a shell, a motor device and a mechanism component, wherein the motor device comprises a stator and a rotor; the stator of the motor device is fixed on the shell; the mechanism component comprises a cylinder device, a bearing part and a crankshaft part; the bearing part is arranged between the cylinder device and the motor device; the crankshaft part is in lap joint with the rotor; the bearing part comprises an inner ring, an outer ring and a rolling body which is arranged between the inner ring and the outer ring; a noise reduction holding rack is arranged between the inner ring and the outer ring; the rolling body is arranged on the noise reduction holding rack. The invention further discloses a noise reduction holding rack production method. The bearing part in the compressor disclosed by the invention is a holding rack manufactured by using a production process of noise reduction holding racks, when the bearing part is rotated at a high speed, a small amount of lubricating oil is temporarily retained in a convex part of an arc-shaped cavity under the action of centrifugalforce, then noise caused by vibration in the rotation process of the bearing part is reduced, and furthermore noise made when the compressor is used is reduced.

Description

technical field [0001] The invention relates to a compressor device with a noise-reducing bearing and a production method for a noise-reducing cage, belonging to the field of bearings. Background technique [0002] Bearing is 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. Bearing noise is a sound phenomenon produced by the vibration and collision of parts during the operation of the bearing. In order to reduce bearing noise, such as the Chinese invention patent CN103899657B discloses a shock-absorbing pneumatic bearing, which includes: the shaft wheel is placed in the cylinder liner, the rotating shaft passes through the cylinder liner and the shaft wheel, and the rotating shaft and the shaft wheel are fixed with a shaft pin. The air nozzle is installed on the top cover, and then the top cover is tightly sealed on both...

AI Technical Summary

Problems solved by technology

The invention uses high-pressure gas to isolate the shaft wheel and the cylinder liner of the bearing shaft. The shaft wheel does not generate friction when rotating in the cylinder liner. At the same time, the distance between the shaft wheel and the hanging shaft changes with the instantaneous load of the hanging shaft, thereby playing The effect of shock absorption, but because the air pressure control is unsafe and uncontrollable, and the effect of air pressure shock absorption is poor
