Processing of bearings

Processing of bearings
Bearing is an important component in 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. Rolling bearings are generally composed of four parts: outer ring, inner ring, rolling body and cage. According to the shape of rolling elements, rolling bearings are divided into two categories: ball bearings and roller bearings. Although there are many types of rolling bearings, there are differences in their structural types, tolerance levels, material selection, and processing methods, but their basic manufacturing processes are similar. Let ’s briefly introduce the processing process of bearing components: bearings can bear radial loads And axial load. Can work at higher speeds. The larger the contact angle, the higher the axial load capacity. High-precision and high-speed bearings usually adopt a contact angle of 15 degrees. Under the action of axial force, the contact angle will increase. Single-row bearings can only bear axial load in one direction. When bearing radial load, it will cause additional axial force. And can only limit the axial displacement of the shaft or housing in one direction. If it is installed in pairs, the outer rings of a pair of bearings are opposite, that is, the wide end face is opposite to the wide end face, and the narrow end face is opposite to the narrow end face. This prevents additional axial forces and limits the shaft or housing to axial clearance in both directions.
