Abstract
An assembly retainer for a self-aligning pelletizer cutter hub having a self-aligning driving connection between a cutter hub and a drive shaft for the hub in which the cutter hub is capable of universal pivotal movement as well as a driving connection through diametrically located recesses and spherical balls. The retainer is supported on the hub to retain the torque transmitting balls in the recesses. In one embodiment, the balls are retained by circular plates attached to the hub in position to form a closure for an open end of each recess. In another embodiment, spring pins are inserted in passageways in the hub with one end extending into an open end of said recesses to form an obstruction in each recess.
