Paper Abstract

In all accuracy indexes of gears, measurement of involute tooth profile's error is a difficult technical problem. A doubledisc instrument for measuring involute is introduced, which can be used to measure reference involute. The main errors sources of the instrument are analyzed, and all measurement errors are simulated by Mont-Carlo method. After analyzing error sequence, the double disc instrument's measurement uncertainty is 0.45μm when measuring gear (m=4, z=30, α=20°), which is less than the value evaluated by GUM method, and more reliable and accurate.
