在我们的工作中,滚刀的测量工作是经常碰到的,其主要项目之一的螺旋线偏差,除动态测量可直接得到外,其它测量方法均要从静态测量所得数据中计算出来。其测量方法,已为广大计量人员所熟悉,在此不必多谈,现仅谈谈滚刀如何从静态测量数据中求出规定范围内(如一转、三转等)的螺旋线极限偏差。在《小模数齿轮测量手册》一书及其它某些资料中,有关求出规定范围内的螺旋线极限偏差的方法介绍,但是,这些资料所介绍的求一转中螺 In our work, hob measurement work is often encountered, one of its major projects of the helix deviation, in addition to dynamic measurements can be obtained directly, the other measurement methods are calculated from the static measurement data. The measurement method, has been familiar to the majority of measurement staff, in this need not talk about, now only talk about how the hob from the static measurement data to determine the required range (such as a turn, three turn, etc.) of the spiral limit deviation. In the “Small Modulus Gear Measurement Manual,” a book and some other information on the determination of the limits of the spiral within the limits of the method introduced, however,
