摘　　要：基于对比试验探究了抛光磨削工艺对齿轮振动噪声的影响。试验对象分别为抛光磨削齿轮和常规磨削齿轮各一对。试验前,对两齿轮副的齿形齿向形貌和粗糙度进行检测以得到齿面微观形貌特征;之后,对两齿轮副进行齿轮运转试验,在不同的转速下,采集振动噪声数据,利用Matlab对试验数据处理,得到频谱和噪声变化趋势;结合两齿轮副的表面形貌特征,分析探讨了抛光磨削工艺对齿轮振动噪声的影响。由频谱对比得知,抛光磨削齿轮的振动加速度明显低于常规磨削齿轮;由噪声结果对比得知,300~600 r/min时,抛光磨削齿轮比常规磨削齿轮噪声略低;700~1 000 r/min时,两齿轮副声增加均较为缓慢;1 100~1 400 r/min时,常规磨削齿轮振动噪声比抛光磨削齿轮增加的更快。The effect of polishing and grinding process on the vibration and noise of gear is investigated based on comparative experiments.The test objects are one pair of polishing grinding gear and one pair of conventional grinding gear.Before the test,the profile and roughness of the two gear pairs are detected to obtain the micro-profile characteristics of the tooth surface.After that,the gear running test is carried out with the two gear pairs.The vibration and noise data are collected at different speeds,and Matlab is used to process the test data to obtain the frequency spectrum and noise variation trend.Based on the surface morphology of the two gear pairs,the influence of polishing and grinding process on the vibration and noise of the gear is analyzed and discussed.From the frequency spectrum comparison,the vibration acceleration of polished grinding gear is obviously lower than that of conventional grinding gear.According to the comparison of noise results,the noise of polished grinding gear is slightly lower than that of conventional grinding gear at 300~600 t/min.The sound of both gear pairs increased slowly at 700~1 000 r/min.In the range of 1 100~1 400 r/min,the vibration noise of conventional grinding gear increases faster than that of polished grinding gear.
