Apparatus for machining bearing rolls

摘要

An apparatus for machining bearing balls has a motor which drives, through an elastic coupling, a gear box connected by a telescoping coupling to a crown gear device. The output of the crown-gearing is applied to a rotatable disk. An electric motor drives a gear pump which has its output connected by an electromagnetic distributor to a hydraulic cylinder adapted to press the rotatable disk against a fixed disk, the balls being circulated between the disk and machine (filed, ground or lapped) therebetween.
