Motor-driven conveyor roller for conveying systems for conveying containers, pallets and the like

摘要

Motor-driven conveyor roller for conveying systems for conveying containers, pallets and the like, having– a roller body (100), the outer circumferential surface of which represents a support surface for material to be conveyed,– a drive unit (200), the inside of an interior space of the roller body is arranged,– a for transmitting a torque from the drive unit to an inner circumferential surface of the interior of the roller body constructed coupling unit (300), which• a clamping bush (310),• a to the clamping bushing is axially movable clamping ring (320),• a fastening element (340) for holding an axial bearing clamping ring to the clamping bush in a tensioned position, and• a pressure ring (330), which between a clamping surface (311) of the clamping bushing and the clamping surface (321) of the clamping ring in the clamped position is fixed and in the clamped position on its outer circumference in the frictional engagement with the inner peripheral surface (132) of the interior of the roller body is,comprises,characterized in that the clamping bush of the coupling element with an inner hollow space (302) and the fastening element (340) extending radially outward from this cavity is arranged.
