Abstract:
A motor mounting apparatus supporting a motor relative to a base for relative rotation about a pivot axis and controlling tension in an endless loop driving element wherein the endless loop driving element encompasses a drive member driven by the motor about a drive member axis and a driven member coupled to a load and driven by the driving element about a driven member axis to transmit power from the motor to the load, the apparatus comprising:a threaded shaft, rotatable by a user about a shaft axis, said shaft fixed relative to a first one of the base and motor;a rider, carried by the threaded shaft so that rotation of the threaded shaft about the shaft axis produces longitudinal translation of the rider along the shaft axis relative to said first one of the base and motor; anda rigid link having a first end pivotally coupled to the rider and a second end pivotally coupled to a second one of the base and motor;wherein a first plane containing the pivot axis and the drive member axis is within 15 degrees of orthogonal to a second plane containing the drive member axis and the driven member axis.
