Transmission mechanism for driven roller, e.g. for moving poster, comprising truncated conical disc engaging with elastic ring inside roller tube

摘要

Transmission mechanism for a tubular roller (1) with an internal electric motor (2) comprises a truncated conical disc (9) on the motor shaft (8) engaging with a concentric elastic ring (10) between the disc and the inner surface of the roller. Transmission mechanism for a tubular roller (1) with an internal electric motor (2) comprises a truncated conical disc (9) on the motor shaft (8) engaging with a concentric elastic ring (10) between the disc and the inner surface of the roller. The edge of the disc is angled at 2 to 25 deg , preferably about 10 deg , and a plate (11) applying a lateral pressure against the ring is fastened to the end of the motor shaft by a screw (12).
