ABSTRACT:
Disclosed is a coupling device in the form of an overrunning clutch particularly adapted for "holdback", stand-by drive and "creep" drive applications. A one-way clutch means, preferably in the form of a sprag clutch provides selective drive between a normally driven member and a normally passive member. The "passive" member may be retained against any rotation or may be driven at any speed less than that of the normally driven member. In the illustrated embodiment the normally driven member comprises a sleeve adapted to accept a shaft. The sleeve is drivingly connected to the outer race of the one-way clutch. The inner race of the overrunning clutch is fixed to a housing for the assembly and serves as the passive drive member. Means are provided thereon for connection to a stationary member or an auxiliary drive. The passive member is supported on the normally driven member by a pair of bearing means one on either side of the one-way clutch. One bearing means is supported on the exterior of the normally driven means and one is supported within said means. A lubrication system is provided which includes a fill plug, a level check plug and a vent plug in the housing.
