Description

technical field [0001] The invention relates to a processing method of an angular contact ball bearing, in particular to a processing method used in a production line of an angular contact ball bearing ring. Background technique [0002] Angular contact ball bearing is a kind of rolling bearing, which can bear radial load and axial load at the same time, and has high rotation accuracy and maximum operating speed; the larger the contact angle, the higher the axial load capacity. Under the action of axial force, the angular contact ball bearing's contact angle will increase with the increase of axial force. Compared with traditional deep groove ball bearings, angular contact ball bearings are more suitable for high-speed precision rotating machinery, such as high-speed precision machine tool spindles, aero-engine spindles, high-speed precision motors, etc. In recent years, with the rapid development of the machine tool industry, aviation industry, and motor industry, the dema...

Problems solved by technology

The production efficiency is very low due to the lack of in-line production

[0010] The existing machining method of the outer diameter of the outer ring of the angular contact ball bearing is centerless grinding. Since there is no fixed grinding reference, it is difficult to guarantee the perpendicularity between the outer diameter of the outer ring and the end face

Therefore, when entering the subsequent groove grinding process, the verticality error will further affect the processing accuracy of the ferrule

[0011] In the existing grinding machine equipment used for grinding angular contact ball bearing rings, the workpiece shaft and the main shaft of the grinding wheel dresser are supported by rolling bearings. Due to the contact wear of the rolling bearings, the precision life of the main shaft is low, and the user needs to replace the bearing or the main shaft regularly, resulting in The continuous production stability of the product is affected, the maintenance frequency is high, and the product consistency is difficult to be guaranteed

[0012] Due to the above-mentioned shortcomings in the production of existing angular contact ball bearing rings, the production efficiency of angular contact ball bearings is low and the manufacturing cost is high, which limits the wide application of angular contact ball bearings in the field of high-speed precision machinery
