Embodiment 1

[0032] A production process of a ceramic ball bearing ring is carried out according to the following process steps:

[0033] ①Processing and forming: use machine tools to process the billet into a ring and then carry out the cold rolling and expanding process. The cold rolling and expanding process basically processes and shapes the ferrule, and adopts heat treatment and cryogenic treatment: the quenching hardness of heat treatment is HRC62, and the cryogenic temperature is controlled at minus 70 ℃;

[0034] ② Grinding and polishing: The workpiece after the cold rolling and expanding process is subjected to initial grinding and fine grinding process, and the plane, outer diameter, inner hole, and groove of the ferrule are ground to achieve the dimensional accuracy of the part; finally, the ultra-fine grinding process is carried out. Carry out ultra-fine grinding to the groove of bearing ring, reduce the roughness of groove and improve the roundness of groove, and its roughness...

Abstract

The invention relates to a production process of a ceramic ball bearing ring and belongs to the field of bearings. The production process of the ceramic ball bearing ring comprises a ring processing and shaping process and a grinding and polishing process, wherein the grinding and polishing process comprises the steps of rough grinding, fine grinding and ultra-fine grinding; and grinding agents at all the grinding stages in the process comprise a rough grinding agent, a fine grinding agent and an ultra-fine grinding agent. The production process has the beneficial effects that the grinding agents are matched with one another when in use in all the grinding stages; and the effects that the grinding efficiency is high, the pollution to a ceramic body is less, the grinding efficiency is improved, and the grinding time is reduced can be achieved.

Description

technical field [0001] The invention relates to a production process of a ceramic ball bearing ring, which belongs to the field of bearings. Background technique [0002] The ball bearing is a kind of rolling bearing. The ball is installed in the middle of the inner steel ring and the outer steel ring, which can bear a large load. Among them, ceramic ball bearings have attracted much attention because of their unique characteristics and wide application fields. At present, silicon nitride ceramic ball bearings are widely used. Its advantages are: high limit speed, good precision retention, small starting torque, high rigidity of ceramic ball bearings, good dry running performance, and long life. It is very suitable for maintaining high precision and long life under high speed, high temperature, corrosion and radiation conditions. Time runs. In addition, the hardness of silicon nitride ceramics is twice as high as that of bearing steel, and the elastic modulus is about 1 / 3...
