Description

technical field [0001] The invention belongs to the field of mechanical processing, and relates to a device for polishing the inner ring of a journal bearing of a screw rotor. Background technique [0002] Bearing is an important part of mechanical equipment. Its main function is to support the mechanical rotating body, reduce the friction coefficient during its movement, and ensure its rotation accuracy. The screw rotor is rotatably supported in the housing by one or more bearings. The accuracy of the inner ring of the bearing will determine the coaxiality of the screw rotor and the bearing. The larger the error will have a negative impact on the operation of the screw rotor, it is prone to jitter, noise, leading to premature bearing failure. [0003] After searching, for example, Chinese patent literature discloses an intelligent production line for bearing inner ring grinding machine processing [patent number: ZL201620571452.X; authorized announcement number: CN205817474...
