Description

Technical Field

[0001] The utility model relates to the technical field of bearing surface grinding, in particular to a surface grinding device for bearing processing. Background Art

[0002] A bearing is a mechanical element used to support and reduce friction between rotating parts in a mechanical device. They are usually used to support rotating parts on a rotating shaft and allow these parts to reduce friction and transmit force in relative motion. Bearings usually consist of an inner ring, an outer ring, rolling elements (such as balls, rollers, sliders, etc.) and a retainer (to maintain the relative position of the rolling elements). Different types of bearings are suitable for different applications, including ball bearings, roller bearings, and plain bearings. They are widely used in various fields such as automobiles, aviation, industrial equipment, and home appliances. The surface of the bearing needs to be polished during the processing process to reduce the roughness of the bearing surface and make its surface smoother. This helps to reduce friction and wear and improve the operating efficiency and life of the bearing.

The double-end surface grinding device for bearing processing realizes the grinding of the double end surfaces of the bearing through the use of the bearing fixing device and the grinding device, thereby improving the grinding efficiency of the bearing and improving the practicality of the device.
