Take the manufacture of Z535 variable speedgearbox for example, to analyze the causes of gear noise and effective technological means of noise control.
以制造z 535变速齿轮箱为例，分析了齿轮噪声的产生原因和控制噪声所采用的有效工艺手段。

According to the frequent oscillation of high-speed axle of speed increasing box, the gear strength is checked.
针对生产中增速箱的高速轴振动频繁现象，对其齿轮强度进行了校核。
