ABSTRACT:
An electric motor changes the output speed of a mechanically-adjustable variable speed drive apparatus by controlled bi-directional rotation of a shifting screw engaged with a centerpiece assembly. In general, the dry traction apparatus may be either of the single disk or double disk type (including modifications thereof). The motor drive shaft is co-axially aligned and coupled with the shifting screw, and includes a particular thrust bearing arrangement which accepts axial thrust in either direction generated by rotational operation of such motor. A limit switch mechanism, including a spring-loaded limit switch actuation element, also automatically controls motor operation by responding to controlled shifting of the centerpiece element. A protective shear pin and a torque arm arrangement further facilitate co-axial coupling of the motor with the shifting screw. An output friction ring of the drive apparatus may optionally be outfitted with a tachometer ring to facilitate monitoring of the output rotational speed.
