摘要： A and machine for lapping hypoid gear pairs by a new method to provide improved tooth engagement characteristics, resulting in good sound qualities over a remarkably increased range of pinion axial adjustment in assembly. The method employs a plurality of special lapping cycles acting on the periphery of the gear teeth to achieve full control of tooth surface mismatch. The lapping machine controls backlash settings, set-overs, and all lapping motions with only three actuators, carries out the new method and achieves a versatility of lapping control far exceeding that available in prior art machines. A control panel provides an array of thumbwheel switches, graduated dials and selector switches for rapid entry of all lapping cycle control data, i.e., backlash, lapping motions and motion rates, number of passes, speeds and torques, all of these parameters being controlled independently for both forward and reverse sides of the teeth. The control panel also permits ready selection of alternative lapping methods including conventional one-cycle lapping methods as well as the novel multi-cycle methods disclosed herein. Stepping motors, responsive to data entered into the control panel, operate linear actuators to displace the gear spindle for effecting all lapping motions and relative gear-to-pinion displacements. The machine is designed with a vertically oriented pinion spindle to reduce floor space and to facilitate adaptation to full automation and is also designed with all relative lapping motions being accomplished by movement of the gear spindle on a unique support structure specially designed to simplify machine control functions.
