Abstract
An automatic testing apparatus is proposed for testing the circular spacing of gears and, in a further development, for simultaneously testing the deviations in gear concentricity, tooth thickness and tooth gap. The testing of circular spacing is accomplished in only one revolution simultaneously for both the right and left tooth flanks of the gear, and the measurement values thus obtained can be used as well for ascertaining the deviations in gear concentricity, tooth thickness and tooth gaps.
