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 ring-type mounting flange releasably secured between the gearbox and an internal wall of the drum. Radial screws extend through oversize apertures in the wall of the drum for releasably attaching the gearbox to the drum. A motor mounting flange locates the motor in driving position adjacent the gearbox. The motor mounting flange is supported on a reactor tube extending out of the drum and the reactor tube is supported by an external anchor plate. The drive mechanism may be situated at one end of the drum, and a bearing assembly of similar character to the drive mechanism, but using a rim-mounted dummy gearbox, may be provided internally at the other end of the drum. 7
