Abstract

A drive roll or idler roll system comprises an idler roll shaft 10 having a groove 12 within its surface and an idler roll. The idler roll comprises a cylindrical outer roll surface 14 with three separately spaced interior spring fingers 16 that engage the groove of the shaft. In addition, the interior of the idler roll also has three bearing surfaces 18 on the roll shaft to assist in providing accurate axial location and retention of the roll on the shaft. This device can be inexpensively molded in one piece from plastic and securely fitted onto a shaft without the use of additional springs or collars and may be used as an idler roll in a sheet-feeding device.
