Torque-responsive power transmission assembly

Abstract From the Canadian patent

Abstract of the Disclosure, In the torque-responsive variable effective diameter driven, sheave assembly of a variable speed V-belt drive the sheave, halves are relatively axially movable but keyed or splined together so as to prevent relative rotation between them. Torque response is provided downstream in the drive train by arranging for relative rotational motion between drive elements such as the driven shaft (which carries the driven sheave) and an output sheave to generate axial movement of one of the sheave halves. In an alternative embodiment, relative rotational movement generating axial adjustment of the sheave half takes place between the driven sheave halves moving rotationally …
