ABSTRACT:
A gear holding fixture is provided so that the appropriate position upon a gear tooth may be placed in line with an indenting device on testing equipment. The fixture includes a base that supports a movable rack, the rack including a plurality of teeth. The gear being tested is supported upon the movable rack in a way wherein the teeth on the gear intermesh with the teeth on the rack. The fixture also includes a gear axle restraint that is selectively movable depending on whether the gear is being tested or being replaced. The gear axle restraint in a gear testing position abuts an axle that supports the gear and extends along the gear's axis of rotation. This reduces the gear to only rotational movement. Thus, as the rack is moved incrementally along the base, the teeth on the rack drive the teeth of the gear, causing the gear to rotate.
