ABSTRACT:
A quick change gear apparatus provides a system which shortens time of spindle machine gear changes to approximately ten percent of that previously required for gear change operations. In a preferred form, the apparatus includes a cylindrical spacer juxtaposed against a face of a gear which is secured between the spacer and a shoulder on a gear shaft. A split washer is also employed to permit the quick change operation by virtue of the loosening of a cap screw secured in a free end of the gear shaft. The cap screw contains a head which retains the split washer and assures that the split washer is urged axially against the spacer and gear members on the shaft. A partial turn of the cap screw will enable radial removal of the split washer, to thereby permit subsequent axial removals of the spacer and gear.
