钢环组是金属带的关键组件之一 ,它的受力状况关系到金属带的承载能力和使用寿命。本文分析了钢环组在静态下和传动中的受力情况 ,建立了钢环组的力学模型 ,得到了钢环应力的求解公式 ,并分析了钢环的应力变化规律 。

The steel rings is a key part of metal V-belt, forces acting on it affects the driving capacity and working life of metal V-belt. In this paper, forces acting on it are analyzed in the static state and dynamic state respectively, mechanics model of steel rings is established. The stress computational formula is derived, and changing rule of stress is analyzed. The paper provides theoretics basis for metal V-belt type CVT's research and design.
