ABSTRACT:
An improved drive for a satellite dish assembly. A flat, steel arc is fixedly connected at its two ends to the pivotal frame of the dish assembly, which steel arc is provided with a series of rows of mini-gear teeth on its outer surface. The steel arc is sandwiched between a rotatable knurled hub and a roller bearing, which knurled hub is provided with a series of rows of mini-diamond-shaped recesses for meshing engagement and forming of the gear teeth of the steel arc, in order to pivot the steel arc, and, therefore, the frame and dish mounted thereto, through a desired arc for aiming the satellite dish. The knurled hub is driven by a motor assembly, the motor assembly, knurled hub, and bearing being mounted to a free end of a cantilevered support arm, the other end of which is fixedly connected to a housing for the pivot shaft of the dish assembly about which the frame and satellite dish rotate for aiming purposes.
