Abstract
A large rectangular rotary table includes a fabricated tubular metal frame having top plates for supporting fixtures and large motor vehicle parts. A center portion of the table frame is supported by an annular turret bearing mounted on a base plate spaced above a floor plate by adjustable leveling screws. A drive unit is also supported by the base plate within the bearing and the center portion of the table frame and includes a planocentric gear reducer driven by an electric servo motor projecting above the table. A laterally projecting torque arm is mounted on the output of the gear reducer and is connected to the table frame by a sliding drive pin assembly which prevents radial loads on the gear reducer when the table is indexed. A fluid actuated table locating pin alternately engages a locating seat on each end of the table after the table is indexed.
