Abstract
A tester for backlash-free rolling of gears with a mating gear generally comprises a base, a stationary spindle on which a test gear can be mounted and which can be driven by a motor; an oscillating slide on which a rotary mounting device is located with an axis of rotation for loosely rotating the mating gear and which slide being guided for easy movement in the direction of the center distance of the two gears; first means for setting a specified test center distance between the two gears; second means providing a specifiable test force for a constant tight mesh of the two gears; and third means for measuring center distance variations during the rotation of two gears. To simplify and reduce design costs of such testers, the stationary part of a linear motor is disposed on the base and the moveable part thereof is disposed to the oscillating slide, and an associated separate CNC control is provided to allow the linear motor to be used for said three means.
