Abstract
An internally mounted rotary drum drive mechanism optimizes the space within a drum by utilizing a rim-mounted, motor-driven rotating gearbox for applying torque to the drum through a split ring-type mounting flange releasably secured between the gearbox and an internal wall of the drum. Radial screws extend through the wall of the drum for releasably attaching the mounting flange and axial screws attach the mounting flange to the gearbox housing. A motor mounting flange locates the motor in driving position adjacent the gearbox and the motor mounting flange is provided with a peripheral notch for obtaining access to the gearbox mounting flange fasteners during assembly and dismantling of the mechanism.
