Abstract
A slew drive includes a housing, a worm shaft having a worm thread carried within the housing for rotational movement and a torque tube having an outer surface. The torque tube is carried by the housing for rotational movement perpendicularly to the worm shaft and worm thread. A ring gear section having teeth is carried by the torque tube with the teeth engaging the worm threads. An inner raceway is fabricated as an integral part of the torque tube. An outer raceway is fabricated as an integral part of the housing, the outer raceway radially overlying the inner raceway, and bearing elements captured between the inner raceway and the outer raceway.
