A continuously variable transmission including a first pulley means, a second pulley means and an elongate, flexible endless transmission element that is passed over both the first pulley means and the second pulley means, wherein the first pulley means include two sheaves which are adjustable in an axial direction of the first rotation axis line, and an adjusting means for moving the two adjustable sheaves toward and away from each other in the axial direction for setting an operative radius of the first pulley means at which the transmission element is passed over the first pulley means, wherein the first pulley means is provided with alignment means for causing the two movable sheaves to jointly move additionally in the axial direction of the first rotation axis under the influence of a force exerted in axial direction on the first pulley means by the transmission element while maintaining the operative radius.

The present invention relates to a pulley structure (1) equipped with an outer rotating body (2), an inner rotating body (3), and a coil spring (4) provided between the outer rotating body (2) and the inner rotating body (3). The coil spring (4) is configured so as to undergo torsional deformation in a diameter-expanding or a diameter-contracting direction, thereby engaging the outer rotating body (2) and the inner rotating body (3) and transmitting torque, and to undergo torsional deformation in the direction opposite the direction in which torque is transmitted, thereby entering a disengaged state in which the coil spring slides with the outer rotating body (2) or the inner rotating body (3), thus interrupting the transmission of torque. The number of windings of the coil spring (4) is in a range between [M-0.125] and M (both inclusive), where M is a natural number.

A high torque sprocket includes a body defining an outer periphery and a hub section defining an inner surface for engaging a bushing. A continuous toothed structure is disposed on the outer periphery of the body, and a textile reinforcement embedded in the body adjacent the inner surface of the hub section. The body is formed of a castable polymer material. In some cases, one or two optional flanges are disposed on side(s) of the body immediately adjacent the continuous toothed structure, in some aspects, a textile reinforcement may be embedded in a surface of the flange(s) immediately adjacent the continuous toothed structure. In some aspects, ultra-high molecular weight polyethylene (UHMWPE) is incorporated into the castable polymer material mixture in an amount suitable to provide increased durability to the sprocket.
