斜齿轮和螺旋齿轮导程的测量有很多种方法,如按齿距测量,以螺旋角计算等。这些方法操作既不方便且测得的数值也不够精确,因而直接影响齿轮啮合质量。为此,我们制造了一架专门测量导程用的测量仪,测量仪构造简单、精确度高、操作方便。由于初次制造,所以精度较差,测得的数值不够准确,平均在100～200公厘导程内误差为1～1.5公厘,螺旋角误差为3＇～4＇之间,这数值较接近于2～3级齿轮螺旋角的测量误差(1＇～2＇),但比常用的几种测量误差要小。用它测量一般齿轮连计算时间在内也不超过15分
There are many ways to measure helical and helical gear leads, such as pitch measurement, helix angle calculation, and more. These methods are inconvenient to operate and the measured values are not accurate enough to directly affect the gear meshing quality. To this end, we have created a special measuring lead with the measuring instrument, measuring instrument structure is simple, high precision, easy to operate. Due to the initial manufacturing, the accuracy is poor, and the measured values are not accurate enough. The average error is 1 to 1.5 mm in the lead range of 100 to 200 mm and the helix angle error is between 3 and 4, which is closer to 2 ~ 3 gear helix angle measurement error (1 ’~ 2’), but several commonly used than the measurement error is smaller. Use it to measure the general gear with calculation time, including no more than 15 points
