Roller flange, external rotor motor and conveyor roller

A non-electric conveyor roller comprising:

• a roller having a cylindrical shape or a tubular shell shape;
• and
• a roller flange for mounting on an end face of the roller, the roller flange comprising:
• an annular plastic body;
• a bearing;
• and
• a metallic ring surrounding the bearing;
• wherein:
• the metallic ring and the bearing are at least partially embedded in the annular plastic body, wherein the metallic ring is partially molded over by the annular plastic body;
• the metallic ring has elements for force transmission which are positioned on or distributed over a circumferential surface of the annular plastic body;
• and
• the elements for force transmission comprise:
• at least one locking means for transmitting an axial force between the roller and the roller flange, and axially locking the roller to the roller flange;
• and
• at least one pin configured to transmit a torque in either direction between the shaped roller and the roller flange, including the torque being applied to the roller flange by an external drive and the torque being applied to the roller;
• wherein the roller flange comprises a torque transmitter configured to transmit the torque,
• wherein
• the roller flange is arranged to be driven by the external drive via the torque transmitter, and wherein
• the at least one pin transmits the torque from the roller flange to the roller.
