本文论述了扭力簧使用中存在的一种现象——失德现象。分析了产生失稳的原因,以一特定结构对扭力簧因失稳产生的摩擦力矩及扭力簧有效输出力矩进行了讨论,最后提出了减小磨擦力矩,提高扭力簧有效输出力的两条途径。
This article discusses the use of torsion springs in a phenomenon - the phenomenon of moral hazard. The causes of instability are analyzed. The friction moment due to instability of torsion spring and the effective output torque of torsion spring are discussed with a specific structure. Finally, two ways of reducing the friction moment and increasing the effective output force of torsion spring are proposed .
