Abstract

A gear tooth profile testing apparatus has a pair of displaceable measuring devices, one of which is movably mounted on an adjustable base plate and has the other device movably mounted on it. A probe mounted on said other device has biassing means urging it against the profile under test. Drive means displace one of the devices, which transmits signals of relative movements between the two devices to a computer. The computer receives from the other device signals of its movements relative to the base plate. The computer compares these measurements of probe movement with reference values to evaluate deviations in the measured profile.
