ABSTRACT:
An automatic apparatus for testing the spacing of gear teeth in a gear wheel is disclosed, in which the spacing testing is performed for both the left and right flanks of the teeth in a single gear revolution, and the switchover or deflection of the two measuring feelers from one flank to the other against fixed stops is avoided, thereby preventing shocks and vibrations in that measuring position that could produce incorrect measurements.
