一种实用的电梯曳引摩擦力计算方法

A Practical Calculation Method of Traction Friction of Elevators

且前电梯的曳引条件的验算普遍采用国家标准所推荐的欧拉公式，但是欧拉公式不能直接用于计算曳引摩擦力的数值。为此，笔者根据曳引轮和钢丝绳的受力分析。提出了一种实用的电梯曳引摩擦力计算方法。通过实例的计算校验证实．该方法得出的结果与欧拉公式是一致的。

At present, the Euler formula for checking elevator traction conditions generally is recommended by national standard, but the Euler formula cannot be directly used for numerical calculation of traction friction force. Therefore, according to the analysis of the stress of traction sheave and wire rope, a calculation method of practical traction friction is proposed. The result of the method is consistent with the Euler formula through the calculation and verification of an example.
