Method for inspecting gear contact patterns

摘要

In a pair of intermeshing gear teeth each having a tooth surface, the gear contact pattern is inspecting by steps of measuring each tooth surface at a regularly positioned measuring points to detect deviations from a standard gear profile at corresponding measuring points, calculating relative distances between the teeth surfaces at the measuring points, and counting the number of combinations of measuring points wherein the relative distances are within a predetermined limit. Where the counted number is greater than a predetermined value, the pair of gears are accepted.
