ABSTRACT:
A traction sheave in particular for a lift moving machinery, by which the torque is transmitted from the machinery shaft to the ropes supporting the lift cage. The problem in lift traction sheaves of prior art with rigid construction is their objectionably strong tangential vibration, due to the machinery. In the invention this problem has been solved in that the outer rim of the traction sheave is connected to a flange on a hub by the aid of at least one elastic element, and that the outer rim is rotatably carried on the hub.
