ABSTRACT:
An automatic test apparatus for testing circumferential spacing in gears, as well as a further development for testing deviations in tooth thickness, tooth gaps, and gear concentricity, are disclosed, in which with a single revolution of the gear the testing of circumferential spacing is accomplished for both the right and left flanks of the wheel. The values for the deviations in gear concentricity, tooth thickness and tooth gaps are preferably detected at the same time, thereby avoiding the possibility that the measuring feeler can undergo vibration-caused deviations with respect to the tooth flank to be approached for attaining a particular measuring position.
