Patent ID: 8789686

Claim:
A motor-operated conveyor roller for conveyor systems for the purpose of conveying containers, palettes, and the like, having a roller body ( 100 ) with an outer peripheral surface which constitutes a contact surface for conveyed goods, a drive device ( 200 ) which is arranged inside an interior space of the roller body, a coupling device ( 300 ) designed to transmit a torque from the drive device to an inner peripheral surface of the interior space of the roller body, having a clamping bushing ( 310 ), a clamping ring ( 320 ) which can move axially relative to the clamping bushing, a fastener element ( 340 ) for the purpose of holding an axial-mounting clamping ring against the clamping bushing in a tensioned position, and a thrust collar ( 330 ) which is fixed in the tensioned position between a contact surface ( 311 ) of the clamping bushing and a contact surface ( 321 ) of the clamping ring, and which in the tensioned position has a friction-fit connection via the outer periphery thereof to the inner peripheral surface ( 132 ) of the interior space of the roller body, characterized in that the clamping bushing of the coupling element has an inner hollow space ( 302 ), and the fastener element ( 340 ) is arranged outward from the radial center of this hollow space.
