摘要：
To a cquire accurate assessment of the condition of gear wear, the gear pair wear test was designed, and the whole life cycle experiment of gear wear was carried out. Five wear stages were acquired by wear rate, wear particle fractal dimension, vibration signal and working condition. The matter-element assessment method was selected as the evaluation method of gear wear condition for the method makes it simple to calculate and easy to determine the weights. The matter-element evaluation model based on fractal dimension of wear particle group was established and verified by test data extracted from wear test. The results show that accurate assessments in different conditions of gear wear are acquired by matter-element model, and the assessment accuracy rate of wear conditions reaches 91.67%. ©, 2015, Central South University of Technology.
