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...


1. A self-aligning cutter hub assembly for use in an underwater pelletizer connected to a drive shaft and enabling cutter blades on a cutter hub to be aligned with and move in parallel relation to a die face on an extrusion die plate, said cutter hub assembly comprising a centrally located axial bore defined by an inner surface on said cutter hub, said inner surface of the bore being partially spherical, an adapter rigidly mountable on an end of said drive shaft and received in said bore, said adapter including a partially spherical outer surface with th...
