Abstract
A conversion device that is structured to be coupled to the rotating axle of a motor and to an output assembly. The output assembly has an elongated shaft with an axis extending generally perpendicular to the axis of the motor axle. The output assembly further is coupled to a frame to resist movement in an axial direction. The conversion device includes an eccentric hub having a disk with a sidewall extending from the perimeter thereby forming a recess and a yoke having a shaft and an attachment pin. The disk is coupled to the motor axle. The yoke shaft is disposed within the eccentric hub recess and the attachment pin is pivotally coupled to the output assembly. As the eccentric hub is rotated by the motor, the hub causes the yoke moves in a circular path. The circular path of the yoke has directional components that are parallel to the axis of the output assembly shaft and perpendicular to the axis of the output assembly shaft. The attachment pin allows the yoke to pivot in a direction parallel to the axis of the output assembly shaft. Thus, only the motion perpendicular to the axis of the output assembly shaft is transferred to the output assembly shaft. This motion is a recipro…
