ABSTRACT:
In a gear probe for testing the shape and orientation of gear flanks, a control and computer unit is used to effect the necessary positioning between the gear flank to be tested and a measuring sensor. First the gear is positioned coarsely; during this step a transmission disc and a linear transmission track are out of engagement with one another. Thereafter, the measuring sensor is advanced into the tooth gap and a fine positioning for a zero balancing of a potentiometer of the measuring sensor is effected by automatically displacing the linear transmission track with respect to the carriage on which it is mounted or by automatically changing the relative angular position between the gear to be tested and the transmission track. All displacements of apparatus components for the coarse and fine positioning as well as for the performance of the measuring process proper are automatically effected by the program-controlled control and computer unit.
