AI Technical Summary

Technical Problem

The traditional bearing outer ring end surface grinding method is prone to excessive temperatures during the grinding process, which leads to deformation of the bearing and affects its accuracy, performance and life.

Method used

A bearing end surface grinding device is designed, including a grinding box, a grinding wheel, a fixing plate, a cooling oil circulation system and a filter. Cooling oil is sprayed through nozzles on the surface of the grinding wheel to cool down; filter and scraper are combined to intercept and clean the debris generated during grinding, ensuring the cleanliness and circulation of the cooling oil.

Benefits of technology

It effectively reduces the temperature during bearing grinding, reduces deformation caused by high temperature, and improves the grinding accuracy and surface quality of the bearing outer ring.

Abstract

The invention relates to the technical field of bearing grinding, and discloses a bearing end face grinding device which comprises a grinding box and two grinding wheels rotationally connected to the interior of the grinding box, a fixing plate used for supporting a bearing is arranged between the two grinding wheels, and the two ends of the fixing plate are both connected to the interior of the grinding box; the bottom in the grinding box is filled with cooling oil, the inner wall of the grinding box is connected with a filter screen, a circulating pump is installed in the grinding box, a water outlet of the circulating pump is connected with a nozzle through a pipeline, a water outlet of the nozzle is located above any grinding wheel, and the inner wall of the water outlet of the nozzle is connected with a one-way valve. After cooling oil in the grinding box is pumped by the circulating pump to enter the pipeline, the cooling oil is sprayed out from the pipeline to the nozzle, and the cooling oil is sprayed on the surface of the grinding wheel, so that the cooling effect is achieved when the bearing outer ring on the fixing plate and the grinding wheel are ground, bearing deformation caused by high temperature is reduced, and the grinding precision and the surface quality of the bearing outer ring are improved.
