Abstract
A safety drive chuck is disclosed and comprises improved bearing, lubrication, seal, locking ring and key assemblies to increase the operational reliability of the drive chuck. Mounting and maintenance of the chuck are facilitated by relocation of the chuck positioning means on the chuck housing, while chuck operation is facilitated by the smoothing of operative cam surfaces.
