ABSTRACT:
A gear tester method and apparatus for inspecting a contact area between a gear member, such as a spiral bevel or hypnoid gear, relative to a second gear, such as a pinion. The gear tester includes a spray system for coating a portion of the gear member with a gear marking compound, such that when the pinion contacts the gear member the gear marking compound provides an indication or footprint of tooth contact made between the gear member and the pinion. A strobing device illuminates the gear member for inspecting the footprint while the gears are still rotating. In a preferred embodiment, a sensing device senses images of the footprint and a display device displays the sensed images whereby the gear mesh is non-invasively inspected.
