利用车床加工非标准螺纹和模数螺纹时,需要计算挂轮比。下面介绍一种简捷计算方法,供有关同志参考。一、原理和公式计算挂轮比,目的是确定车床主轴和丝杠的转速比。工件螺距的大小,取决于主轴与丝杠的转速比。例如,C 618车床丝杠的螺距是6毫米,丝杠转一圈,车刀就移动6毫米。如 The use of lathe machining non-standard thread and modulus thread, the need to calculate the ratio of hanging wheel. The following describes a simple method of calculation for the comrades for reference. First, the principle and formula Calculate the ratio of hanging wheel, the purpose is to determine the lathe spindle and screw speed ratio. The size of the workpiece pitch, depending on the spindle and screw speed ratio. For example, the thread pitch of a C 618 lathe screw is 6 mm. When the lead screw rotates one turn, the turning tool moves 6 mm. Such as
