渐开线压力角求解新法在渐开线齿轮和齿轮刀具的设计过程中，常常需要计算渐开线０处的压力角ａ．但渐开线函数０—ｔｇａ—ａ是一超越函数．无法求出其反函数，直接求解ａ十分困难。设计中通常采用反查渐开线函数表的方法．但其过程既麻烦．计算精度又不高。这里介绍一种... In order to solve the new law of involute pressure angle, it is often necessary to calculate the pressure angle a at the involute 0 during the design of the involute gear and gear cutter. However, the involute function 0-tga-a is a transcendental function. Can not find its inverse function, direct solution a very difficult. Design commonly used anti-investigation involute function table method. But the process is troublesome. Calculation accuracy is not high. Here to introduce a ...
