<p>A steerable rotatable member (1) such as a pulley, sprocket or timing gear which can be mounted on a shaft (3) so that the plane of the rotatable member may be positioned at selected angles other than a 90 DEG angle to the axis of rotation of the shaft. A torque transmitting member (4), commonly in the shape of a planar disc, is used to operatively connect the shaft and the rim (5) of the rotatable member. The disc radially elongates and laterally flexes as the rotatable member rotates. A sleeve member (7) may be used to connect the disc to the shaft. When used as a driver, a key (53) may be used to transmit power from the shaft to the sleeve. <IMAGE></p> |
