一、前言十字形弹性支承的摩擦力矩极小,在转角小时,转动中心位置基本不变。因此在一些精密设备中得到广泛应用。但是,弹性支承的缺点之一是存在着支承的稳定性问题,所以在设计时除进行强度可靠性计算外,还要进行稳定性可靠性计算。本文就十字形弹性支承在满足其强度可靠性设计之后,对其稳定性的可靠性计算做一探讨。 I. Foreword The friction torque of the cross-shaped elastic support is very small. When the angle is small, the rotation center position is basically the same. So in some precision equipment has been widely used. However, one of the shortcomings of elastic bearings is the stability of the bearing. Therefore, in addition to the calculation of the strength and reliability of the design, stability and reliability calculation should also be carried out. In this paper, after the cross-shaped elastic support to meet the design of the reliability of its strength, reliability of its stability calculations are discussed.
