PWF250型滚刀检查仪能检验滚刀与蜗杆的多项误差,但是对滚刀螺旋沟导程与多头螺纹的单齿距测量没有说明。本文介绍上述两个项目测量方法与精度分析。一、滚刀螺旋沟导程的测量 1.调整测头传感器,使其处于水平位置,即测量头在水平方向。测力旋钮处于90°,用调整心轴(仪器附件)使测头通过中心位置。 The PWF250 hob tester can test hobs and worms for a number of errors, but there is no indication of the single-pitch measurement of hob helix leads and multiple threads. This article describes the above two items measuring method and accuracy analysis. First, hob spiral groove lead measurement 1. Adjust the probe sensor, so that it is in a horizontal position, that is, the measuring head in the horizontal direction. The force-measuring knob is at 90 ° and the probe is passed through the center with the adjusting spindle (accessory).
