ABSTRACT:
A variable speed belt drive bearing assembly including an enclosed helical ramp assembly or torque sensing helix (4) which is mounted on the driven or secondary clutch (20). The helix (4) includes a plurality of ramps (10) that include both an upper bearing surface (13) and a lower bearing surface (9). This arrangement ensures that the torque transferring roller or button (18) is always in contact with either one or both of the surfaces. The cover (68) of the driving or primary clutch assembly (65) includes an enlarged opening (61) to permit the mounting of a sleeve (60) which slides over the engine clutch shaft (66).
