在齿轮加工过程中,检测齿轮的齿圈径向跳动误差时,通常采用偏摆检查仪(见图1)进行。其具体方法是将被测齿轮装在心轴上,并支承在两顶尖间,再把选定的圆棒放入齿轮齿槽内,千分表的测头置于圆棒的最高点处,并使“对零’,然后可逐步测出齿轮的实际齿圈径向跳动误差值。这种方法比较麻烦,劳动强度大,效率低,测量精度不高。 In the gear processing, the gear ring when detecting the radial runout error, usually using bias tester (see Figure 1). The specific method is to test the gear mounted on the mandrel, and supported between the two tops, and then select the round bar into the gear cogging, dial gauge probe at the highest point of the round bar and So that “zero”, and then you can gradually measure the actual gear ring gear radial runout error value.This method is more trouble, labor-intensive, low efficiency, measurement accuracy is not high.
