| 摘 要： | 针对装载机变速器出现尖啸噪声的情况，对其进行了试验测试与分析．从噪声频谱的结构特征判断出变速器噪声主要源于齿轮振动。尖啸噪声是输出轴上大齿轮摩擦自激振动的结果．由于齿轮尖啸噪声产生的机理不同于啮合冲击产生的噪声。因此不能依靠改进结构和提高精度来降低尖啸噪声．根据产生尖啸噪声的摩擦学条件。提出改进齿轮润滑油的摩擦特性．通...

| Abstract: | Experimental measurements were conducted to analyze squeals in transmissions of wheel loaders.The characteristics of the noise spectrum indicate that transmission noise mainly originates from vibrations of gears,and the squeal was a result of friction self-excited vibration of the gear assembled on the output shaft.As the generating mechanism of squeal is different from the noise generated by gear meshing impact,it can not rely on the improvements of structure and accuracy to reduce the squeal.According to ... |
