Abstract: The accurate measurement of the structure parameters of
real tooth surface of spiral bevel gear with the coordinate measuring
machine is the key to evaluate the geometric quality of the real tooth
surface quantificationally, and the base of machine-settings correction.
According to the theoretical tooth surface model, the measuring grids
schema is accomplished on the rotary projection of tooth surface, and
coordinates and the normal of the grids are obtained. Using the data of
grids, the measurement process is completed automatically, the
deviations of the real tooth surface from the theoretical one are
obtained.
Key words: Spiral bevel gear Tooth surface measurement Coordinate
