Simplified Roller Assembly Attachment

Described is a process for mounting rollers on shafts. The process eliminates hub metal, setscrews, diameter expansion, and bonding.

Shaft-mounted rollers such as those used for paper transport must be attached to the shaft in such a manner as to prevent slippage between the roller and the shaft. This is sometimes done by mounting the roller itself to a hub or flange which provides a sliding fit to the shaft. A setscrew or taper pin can then be used to fasten the hub to the shaft.

Other approaches have included bonding the roller to the shaft or expanding the shaft diameter (as by knurling) to provide a tight fit.

It has been found that a shaft holding polyurethane rollers with an inside diameter smaller than the shaft can be assembled easily by providing tapered slots on the shaft. The difference between the shaft diameter and the rollers' inside diameter varies according to the torque required.

The rollers are forced onto the shaft from one end and can be pressed past the preceding slots until positioned at the proper slot.
