ABSTRACT:
A drive assembly for an exercise device is provided. The drive assembly is made up of a base with side supports and an electric motor drive mechanism. The electric motor drive mechanism is an electric motor with a worm gear attached to two driving pulleys via one way clutches. The drive mechanism is supported with outboard bearing mounts located in the side supports. A torque arm and spring assembly restricts rotation of the mechanism, but allows limited rotational movement. This limited movement attenuates shock torsional loads and as a result reduces the structural and electrical size requirements for the overall device.
