摘要
从分析齿轮泵振动噪声产生的机理着手．研究了其振动噪声产生的一般原因及振动的特征频率，在此基础上，对两次试验结果进行了分析，找出了该冷却用齿轮泵产生振动噪声的主要原因．并就此原因探讨了减振降噪的措施。
At first,the producing mechanism of the vibtation and noise of the gial pump is anaiyzed,then the general reason and the characteristic frequencies are studied. After studying the two test results, the author finds out the main reason of the vibtahon and noise produced by the cooling gearpump,and discusses the counter measures to teduce the vibtstion and noise.
