Abstract
A gearbox for a gear motor assembly has a housing defining a chamber and an opening in communication with the chamber. A stationary shaft has one end mounted to a bottom of the chamber and the other end extends toward the opening. A worm wheel is rotatably mounted on the stationary shaft and disposed in the chamber. An output gear connected to the worm wheel protrudes out of the chamber. A cover seals the opening of the chamber. The cover has an annular cover plate with an inner bore and an inner flange extending from an edge of the inner bore towards the bottom of the chamber. The worm wheel has a cylindrical boss that is supported by the inner flange against lateral movement.
