Development of gear dynamic performance testing machine

With the development of gears towards high temperature, pressure, speed and stress, gear measurement, in which only static geometric accuracy is considered, unable to meet current application requirements. While, low precision single function tester constrains measurement dynamic performance. For resolution this problem, based on principle system dynamics several mechanical design techniques, a testing machine has been developed, providing new instruments for testing. On basis research performance test, primary items have determined. The measuring principles each item driving loading form examined. control its corresponding software developed. instrument can not obtain index gear, but also variable working conditions. According actual uncertainty 3.8 μm external disturbance caused by shaft vibration less than 0.6 μm, 5–6 grade requirement.
