Problems solved by technology

Bearings with such requirements are defined as silent bearings for servo motors. The quality of bearings currently used in servo motors varies greatly between domestic and foreign countries. High-quality servo motor manufacturers still have doubts about domestic bearings, so 80% The above-mentioned servo motor factories still use imported bearings. The main reason affecting the mute effect of the motor bearings is the structure of the cage. At present, the bearing manufacturers have made corresponding research on the silent cage of the bearings and achieved certain results. There is still a certain gap in the mute effect of foreign brand bearings

Abstract

The invention belongs to the technical field of bearings, relating to a mute holder of a bearing. The mute holder comprises a round holder body on which a plurality of isolation blocks are uniformly arranged, a pocket hole is formed between every two adjacent isolation blocks, the bottom surface of the pocket hole is a first cambered surface, the side surface of the pocket hole is a cylindrical surface, two sides of an upper end opening of the pocket hole are respectively provided with a fore shaft part, and a second cambered surface is formed on the inner side surface of the fore shaft part.By improving the design of the structure of the holder, the abnormal noise problem of the bearing is effectively solved, the bearing adopted by the bearing provided by the invention can be used for effectively replacing imported bearings, and the use cost of enterprises is reduced; meanwhile, the roller path guide manner and oil storage effect of the bearing are relatively greatly improved.

Description

technical field [0001] The invention belongs to the technical field of bearings and relates to a silent cage for bearings. Background technique [0002] At present, the main characteristics of servo motors for robots are high precision requirements and high speed. When the motor is rotating at high speed, the noise of the whole machine is required to be free of abnormal sound, which requires that the bearings used can adapt to such high speed, high precision, and no difference. According to the sound requirements, after testing and analyzing the bearings that meet the requirements, it is required that no abnormal noise can be heard when the bearings are tested with vibration velocity and vibration acceleration instruments, and the oscilloscope display is a straight line. Bearings with such requirements are defined as silent bearings for servo motors. The quality of bearings currently used in servo motors varies greatly between domestic and foreign countries. High-quality ser...
