摘要

根据梯形螺纹丝杠的特点,首先推导了其端截型上相贯线的方程,并根据材料力学中极惯性矩的概念和叠加原理,得到螺纹丝杠极惯性矩的精确计算公式。该公式中牙形角取不同数值时,即为不同牙形的螺纹。

Abstract

According to the characteristic of the trapezoidal thread screw,at first,the equation of the cross- section shape intersecting line is deduced,and according to the concept of polar moment of inertia in material mechanics and superposition principle,the accurate calculation formula of threaded screw polar moment of inertia is got. In the formula,when the thread tooth angle take different values,the tooth shape is the different thread.
