ABSTRACT:
An apparatus for regulating the lapping pressure during the lapping of two bevel gears at a lapping machine comprising a device for driving one of the bevel gears and for braking the other bevel gear. A control mechanism for adjusting the desired lapping pressure. A differential pressure transmitter is operatively connected with the control mechanism, said differential pressure transmitter serving to measure the liquid-pressure differential brought about by the bearing load in a hydrostatic bearing of one bevel gear in order to regulate the lapping pressure as a function of the bearing load at the aforesaid drive- and braking device.
