ABSTRACT:
A method for orienting a feeler of an apparatus for testing gear flank profiles and flank lines of gear wheels is disclosed, in which the feeler is successively inserted, in two adjacent positions, into an accurately made gap element located on the gear wheel and from the thus ascertained values the location of the point of intersection of the wheel axis with the measuring plane is ascertained, optionally by means of a computer. The gap element, embodied as an orientation gap mounted on the gear wheel, that is approached by the feeler in the first position is rotated with the gear wheel into a second position, and there the feeler, embodied solely by the measuring feeler, is inserted into the same orientation gap. Therefore measurements are made by use of the same orientation gap and the same feeler at two different locations.
