Spline checking fixture

摘要

Checking fixtures for determining the effective tooth spacing along the pitch circle diameter of splined or gear-like members having exterior or interior teeth. Each checking fixture has two sets of L-shaped teeth which interfit in a first position for loading the member to be checked and are separable to a second position for checking the effective tooth spacing along the pitch circle diameter and providing a direct reading of the size of each part checked through a readout device. A wear compensator supports and axially adjusts the position of the member to be checked along the axial length of the partial teeth to prevent localized wear on the partial teeth.
