摘　　要：斜撑离合器在机械领域及航空动力系统起着重要作用,弹簧的径向刚度是影响斜撑离合器脱开转速和楔合性能的重要指标。斜撑离合器弹簧的径向刚度尚无可靠的计算方法,因此将弹簧等效为圆环,推导出弹簧径向刚度的理论计算方法,并通过仿真和试验验证了理论计算的正确性。The sprag clutch plays an important role in mechanical field and aviation power system,and the radial stiffness of spring is an important indicator that affects the disengagement speed and wedging performance of the clutch.There is no reliable calculation method for radial stiffness of the clutch.Therefore,the spring is equivalent to a circular ring,and a theoretical calculation method is derived for radial stiffness of spring.The correctness of theoretical calculation is verified through simulation and experiments.
