ABSTRACT:
An automatic testing apparatus is described for testing the circumferential spacing of gears, for testing deviations in tooth thickness and tooth gaps as well as deviations in gear concentricity, in which with a single revolution of the gear the spacing testing is effected for both the right and the left flanks of the wheel and the values for the gear concentricity deviations, tooth thickness deviations, and tooth gap deviations are preferably ascertained simultaneously, so that a separate measurement apparatus is not required for that purpose.
