摘　　要：在超越离合器的设计过程中,预紧弹簧力的大小对滚柱离合器运转过程中能够及时地脱开与接合有着重要影响,但目前弹簧设计的理论体系尚不完整。通过对滚柱的受力分析,得出弹簧力的范围;之后,采用有限元软件分析了不同弹簧力在离合器接合、超越状态时的压力、响应时间等接触特性,并与理论计算分析结果进行了比较;最后,从弹簧力范围中选取数值进行相应的试验加以验证,通过观察离合器零部件的磨损情况来判断分析的合理性,以此方式来缩短离合器弹簧力的选配过程和测试周期,提高了试验结果的可靠性。In the design process of overrunning clutches,the preload spring force has an important impact on the timely disengagement and engagement of roller clutches during the operation process,but the current spring design theory system is not complete.Through the force analysis of rollers,the range of the spring force is obtained.Then,the finite element software is used to analyze the pressure,response time and other contact char⁃acteristics of different spring forces in the clutch engagement and overrunning state,compared with the theoreti⁃cal calculation and analysis.Finally,the numerical value from the elastic force range for corresponding tests is selected to verify and judge the rationality of the analysis by observing the wear of clutch parts.In this way,the selection process and test cycle of the clutch spring force are shortened,and the reliability of test results is im⁃proved.
