Abstract
A gear tooth flank testing apparatus and method wherein there is provided a housing erectable upon a bed or the like of a gear cutting machine. A measuring feeler is moveably arranged at the housing by means of two cross-wire arranged carriages having associated drive and displacement path measuring devices. The measuring feeler is moveable along two coordinated axes intersecting the axis of the workpiece to be tested. A control and evaluation circuit moves the measuring feeler along a tooth flank of the workpiece and compares the actual settings of the measuring feeler with predetermined reference settings. In particular, at the housing there is arranged a feeler bolt which can be pressed in spaced relationship from the measuring feeler against two neighboring tooth flanks of the workpiece. The feeler bolt is guided to be freely moveable by means of two additional cross-wise arranged carriages parallel to both coordinate axes, and each such carriage likewise has operatively associated therewith a displacement path measuring device which is connected with the control and evaluation circuit.
