Abstract
An overload clutch is described which includes a drive member and a driven member which are coaxial and have concentric cylindrical surfaces which form an annular chamber. One or more rollers of elastomeric material are positioned in the chamber with the rollers in rolling contact with the concentric cylindrical surfaces. Teeth project into the annular chamber from both surfaces and engage the rollers from diametrically opposite positions to transmit torque from the drive to the driven member. Excessive torque causes the rollers to compress between the two engaging teeth, the roller passing between the teeth and allowing the drive member to rotate relative to the driven member.
