刚性镗削主轴的快速计算与分析

Rapid Calculation and Analysis of Rigid Boring Spindles

本文针对组合机床刚性镗削主轴的特点,提出了一种有关轴端挠度、刚度和最佳支承距的快速计算方法。此外,还讨论了支承反力矩的影响,以及如何判断主轴部件刚度薄弱环节等问题。

A mefhod to calculate optimum bearing span of spindle mounted on two bearings is given, which is also a rapid method to calculate the spindle nose deflection and its stiffness.
