Abstract
A chuck for heavy duty applications has a plurality of radially slidable jaw mounts each actuated by an L-shaped lever mounted for rocking motion about a supporting trunnion. The levers each have a leg engaging one of the jaw mounts and another engaging an actuator. An external lubricant receiving port is provided adjacent each trunnion and a multiple conduit lubricant distribution system is provided extending through the supporting trunnion and actuating lever. The chuck body also has a lubricant flow channel through which lubricant flows circumferentially of the chuck to assure uniform distribution, eliminating lubricant concentrations and eccentric weight distribution in the chuck.
