ABSTRACT:
A method and an apparatus for lapping teeth of a pair of gears by rotating one of the gears in engagement with the other gear, while applying a load torque to the other gear and moving the gears relative to each other such that a teeth contact area of the gears is moved in a direction of width of contacting faces of the teeth of the gears, so that the face of each tooth of the gears is lapped over a substantially entire width thereof. A lapping controller is adapted to change at least one of the load torque applied to the relevent gear, rotating speeds of the gears, and a rate of movement of the teeth contact area of the gears, as the gears are moved relative to each other to move the teeth contact area of the gears in the direction of width of the contacting faces of the gears, so that the gear teeth are lapped efficiently, depending upon the configurations and conditions of use of the gears.
