Description
Technical Field
[0001] The utility model relates to the technical field of micro bearings, in particular to a cleaning device for micro bearing steel balls. Background Art
[0002] Micro bearings are small bearings used in micro devices or precision instruments. These bearings usually have the characteristics of high speed, high precision and low friction, and can provide good support and rotation functions. Micro bearings usually consist of inner ring, outer ring, rolling element (such as steel ball or roller) and cage. They are widely used in micro motors, micro fans, medical equipment, optical instruments, computer hard disk drives and other equipment. Due to the small size of micro bearings, their manufacturing and assembly process requirements are very strict. The bearing material is usually selected from high-quality steel or ceramic materials to ensure the life and performance of the bearing.
[0003] During use, the bearing steel balls may be contaminated by dust, oil, corrosive substances, etc. These dirt will adhere to the surface of the steel balls, affecting the rotation efficiency and stability of the bearings. Cleaning can effectively remove these dirt and keep the surface of the steel balls clean. However, most of the existing steel ball cleaning equipment only uses a single brush for cleaning, which is difficult to completely clean the surface of the steel balls and has poor cleaning effect; some cleaning equipment adds stirring blades to stir the steel balls, stirring and cleaning at the same time, although the cleaning effect is improved, but the stirring blades may cause scratches and other damages on the surface of the steel balls during the stirring process, which will reduce the life of the bearings.
