Abstract
A roller having a torque overload release mechanism for use with an accumulating roller conveyor system. A shaft is rotatably mounted to a frame for the conveyor system while a drive sprocket is rotatably mounted to one end of the shaft. A first friction pad is secured to the shaft and abuts against one end of the drive sprocket while a second friction pad is axially slidably mounted to the shaft and abuts against the other axial end of the drive sprocket. A nut variable compresses one or more belleville washers against the second friction pad to thereby drivingly connect the drive sprocket and shaft together and yet permit torque overload release when the torque between the shaft and the sprocket exceeds a predetermined but adjustable amount.
