ABSTRACT:
The tool mounting arrangement employs a bushing within a recessed end of a shaft. The bushing has three lobes with inclined surfaces which abut against an internal conical wall of an annular mounting portion on the end of the shaft. A threaded screw passes through a washer and the grind wheel in non-rotatable relation into threaded relation in the bushing. Turning of the screw causes the bushing to be pulled in a direction out of the shaft so as to radially deform the annular mounting portion into uniform contact with the bore of the grind wheel while the grind wheel is simultaneously abutted square to the shaft axis. The annular mounting portion is provided with equi-spaced circumferentially disposed notches to permit passage of the lobes upon insertion of the bushing into the recess at the end of the shaft. One or more set screws is also provided in the shaft to prevent rotation of the bushing within the recess of the shaft.
