Patent ID: 8474605

Claim:
A conveyor drive shaft assembly comprising: a longitudinal drive shaft comprising: a first end that includes a drive hub having an integral torque limiter adapted for coupling said drive hub to a gear drive shaft and adapted to slip at about 800 ft-lb to about 1300 ft-lb, wherein said integral torque limiter is a radial pin clutch arranged and affixed co-axially with respect to said longitudinal drive shaft, said radial pin clutch comprising: an outer hub affixed to the longitudinal drive shaft, and an inner hub affixed for rotation within said outer hub and for engagement with the gear drive shaft, said inner hub adapted for frictional engagement of the outer hub such that rotation of the inner hub causes rotation of the outer hub until a predetermined upper torque limit is achieved, whereupon said inner hub slips and rotates freely of said outer hub; and an opposed second end.
