Abstract
A drive mechanism for a conveyor. The conveyor includes a frame and a drive spindle that carries a conveyor belt is journalled for rotation on the frame. The spindle has a longitudinal passage and a pair of bushings are disposed in spaced relation in the passage, with the adjacent ends of the bushings spaced apart. Each bushing has a non-circular or hexagonal-shaped opening and a similarly contoured end of a drive shaft is inserted into the opening of one of said bushings. The inner end of the drive shaft is provided with an axial recess and a plunger is located within the recess and is biased outwardly by a spring. A locking member is mounted in a radial hole in the wall of the inner end of the drive shaft and is engaged with a cam surface on the plunger. To assemble or remove the drive shaft from the bushing an elongated tool is inserted in the opposite end of the spindle to move the plunger inwardly against the spring biasing force, thereby releasing the locking member and enabling the drive shaft to be moved relative to the spindle.
