液压马达导轨曲线的设计,对马达性能和寿命有很大影响。以往国内、外一些手册和书本中介绍的导轨曲线为圆弧、正弦、余弦和抛物线(或修正抛物线)导轨。本文以等破坏强度——等接触应力概念为基础,推导出一组公式,得出一种设计导轨的新的切实可行的方法,称等应力导轨设计方法。 文后,还附有实用的电算程序(用Algol语言)。 Hydraulic motor guide rail curve design, the performance and life of the motor have a great impact. In the past, some domestic and foreign manuals and books introduce the guide rail curve arc, sine, cosine and parabolic (or correction parabolic) guide. Based on the concept of equal failure strength-equal contact stress, this paper deduces a set of formulas and gives a new practical method of designing guide rails. After the text, also accompanied by a practical computer program (in Algol language).
