Patent ID: RE44919

Claim:
A conveyor drive roller for supporting and driving a conveyor medium, said conveyor drive roller comprising: a hollow drum defining a rotatable supporting surface having a cylindrical shape, said hollow drum being rotatably connected to a first and a second support structure, said second support structure having a passageway therethrough, and an exterior end comprising a C-flange motor mount sized and shaped to releasably mount a corresponding external motor with a rotor; an internal gear assembly disposed inside said hollow drum; said internal gear assembly being operably connected to said hollow drum; said internal gear assembly also being adapted to releasably couple to said rotor; wherein when said motor is mounted to said C-flange motor mount and said internal gear assembly is releasably coupled to said rotor, through said passageway, rotation of said rotor is transmitted by said internal gear assembly to said hollow drum to cause rotation of said hollow drum about said first and second support structures.
