Abstract
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.
Claims2
An apparatus for machining bearing balls, comprising:
- a fixed machining disk;
- a rotatable machining disk spacedly juxtaposed with said fixed machining disk and adapted to machine bearing balls between said disks;
- a ring gear connected to said rotatable disk;
- a pinion meshing with said ring gear;
- a telescoping-shaft coupling connected to said pinion for rotating same, said pinion and said ring gear being axially connected to said rotatable disk for movement therewith;
- a gearbox having an output shaft connected to said telescoping-shaft coupling and an input shaft;
- an electric motor having a motor shaft;
- and
- an elastic coupling connecting said motor shaft to the input shaft of said gearbox whereby said motor rotates said rotatable disk.
