Abstract
Gear tooth testing apparatus with a rotary test gear mounting has a mechanism for controlling the relative movements of a test probe and of the gear under test, the motions being interconnected by a lever pivotable about the gear mounting axis. The lever has a second pivot connection to a straight-edge that rolls on a rolling cylinder co-rotating with the gear to generate an involute motion, and a third pivot connection to an auxiliary slide associated with the probe. The lever is longitudinally displaceable with respect to all three pivot axes whereby its position relative to the pivot axes at different settings of the apparatus is controllable in a manner limiting the necessary size of the apparatus for a given working capacity.
