Abstract：The Gears are applied widely,and are the key parts in many electric and mechanical equipments.A new kind of gears,the micro-segment gears are possible to replace involute gears in a lot of applications based on their superior performances,but they are limited in use since there are not test methods and techniques for the new gear.To be able to test the profile accuracy of the new gears,a test method is established for the gears by utilizing the current measurement method and equipment for the involute gears with considering the characteristics of the new gears,the theory equation of the new gear profile is given,some calculation formulas of systematic errors,such as the error of measuring heads and the clamping error are derived for gear measuring centers.A micro-segment gear is manufactured by hobbing and milling,and its profile error is measured,the results of the test illustrated that the measuring method for the micro-segment gear profile is practical.
