Abstract

The invention discloses a grinding wheel and main shaft assembly of a spherical roller grinder. The grinding wheel and main shaft assembly is mainly formed by assembling a grinding wheel, a main shaft, a front bearing bush assembly, a thrust frame and a rear bearing bush assembly, and is characterized in that: the width of the grinding wheel is 250 mm; the diameter of the main shaft is 105 mm; the front bearing bush assembly consists of 5 bearing bushes; the rear bearing bush assembly consists of 5 bearing bushes; and the length of each bearing bush is 190 mm. According to the grinding wheel and main shaft assembly, the diameter of the main shaft of the original grinder is changed from original phi 100 mm into phi 105 mm, and the grinding wheel with width of 250 mm can be mounted, so that the length of a roller capable of being grinded reaches up to 240 mm. Since the lubrication mode of the bearing bush is changed from original oil-immersed lubrication into circulating lubrication, the requirements of machining of the large-sized spherical roller grinding can be met, the roughness meets the requirement, and the efficiency is increased to a large extent. The failure rate of equipment is extremely low.

Description

technical field [0001] The invention relates to the technical field of roller grinding processing equipment, in particular to an improvement of a large spherical roller grinding wheel spindle. Background technique [0002] At present, there is no dedicated grinding machine for large-scale spherical roller grinding, but the domestic general cylindrical grinding machine is used. With the increasing demand for rolling bearings, the length of the roller with the largest demand in the bearing is 240mm. The thickness of the grinding wheel reaches about 250mm, and the equipment provided by the machine tool factory can only be equipped with a 100mm grinding wheel. Contents of the invention [0003] The object of the present invention is to provide a grinding wheel spindle assembly for a spherical roller grinder, which overcomes the problem of difficult grinding of large spherical roller bearing rollers, improves work efficiency, and reduces production costs. [0004] The technica...
