一、螺旋测量问题在螺旋角测量时,根据仪器使用规定,应以被测齿轮的基园螺旋角调整仪器螺旋导盘,纵溜板调整在基园直径的位置,横向滑板调整接近左边,此点在轮廓上所需测量的位置,即测头与齿廓侧面的适当位置上,然后进行测量。但是,实践表明,用分度园螺旋角进行调整与检测,比使用基园与基园螺旋角更为合 First, the helical measurement problems In the helical angle measurement, according to the provisions of the instrument, should be measured gear base spiral angle adjustment instrument helical guide plate, vertical slide adjustment in the base diameter of the location, the horizontal slide adjustment close to the left, this Point the desired measurement position on the profile, ie, the proper position of the stylus and side of the tooth profile, and measure. However, practice shows that the adjustment and testing of the indexing garden’s helix angle is more suitable than the use of basement and basement helix angle
