该文通过对大量试验数据的综合分析,介绍了利用不同润滑剂可改变齿轮噪声峰值的频率、降低感觉噪声级,从而改善齿轮传动性能和控制齿轮噪声对环境的污染.“,”In this paper, an amount of test data was analysized. The frequency of peak value of gears grating could be changed and the left noise Level could be decreased by using different lubricant, thus improving the performance of gear drive and controling environment pollution.
