Abstract

A sealed worm wheel gearbox is provided having a worm disposed on a driveshaft. The worm engages a bull gear within the gearbox. Eccentric rotatable driveshaft mounts are mounted on opposite sides of the gearbox to support the driveshaft. The driveshaft axis of rotation is offset from the eccentric rotatable driveshaft mount axis of rotation. Thus, when the eccentric shaft mounts are rotated, the driveshaft moves linearly within the gearbox. In this way, rotation of the eccentric shaft mounts enables engagement and disengagement of the worm and bull gears.
