ABSTRACT:
Gear testing apparatus has a tooth flank probe or feeler displaceable in a spatial co-ordinate system by being mounted on a series of three support members each movable in a different direction. Scales monitoring the member movements feed member position data to a computer in which a movement programme is stored. In one arrangement, the computer programme controls movements of all three members and deviations in tooth flank form cause deflections of the feeler that are evaluated by the computer. In another arrangement, two of the members are driven by the programme data and the third member is displaced by biassing means to hold the feeler against a tooth flank, the computer comparing said displacements with reference values to evaluate deviations in the tooth flank form.
