Abstract
In a gear finishing or other machine having a base, a table support mounting a reciprocal table having a head stock and a tail stock for supporting a workpiece gear or spline to be finished, a pedestal on the base mounting a motor-operated transmission and a depending machine head mounting a power-driven abrasive honing, or other type finishing gear rotatable upon a horizontal or vertical axis, the table support or head being relatively adjustable with respect to the other to bring the workpiece teeth into operative position with respect to the teeth of the finishing gear. The improvement which comprises a first gear train connecting said transmission to said finishing gear for rotation thereof at a predetermined speed. A drive spindle is journalled through said head stock adapted for axial drive engagement with the workpiece gear to be finished. A second gear train interconnects said transmission with said drive spindle for rotation at a predetermined speed. A compensating support device mounts a portion of the second gear train to provide for continuous drive thereof during relative vertical adjustments between the table and head. The first gear train has an accumulated backlash …
