齿轮的周节差对齿轮传动的振动和噪音有很大影响,为了分析齿轮传动引起振动和噪音的原因,常常要对齿轮周节进行测量。众所周知,测量齿轮周节常用齿轮周节仪进行。在没有齿轮周节仪而又需要测量齿轮周节时,建议可用如图1所示的自制周节仪进行。由图1可知,这种仪器的结构极其简单, The difference in the pitch of the gears has a great influence on the vibration and noise of the gear transmission. To analyze the causes of the vibration and noise caused by the gear transmission, the gear pitch is often measured. As we all know, measuring gear week cycle gear cycle instrument commonly used. In the absence of gear cycle instrument but also need to measure the gear circumference, the proposal can be used as shown in Figure 1 homemade Week instrument. From Figure 1 we can see that the structure of this instrument is extremely simple,
