摘要: 为进一步提升超越离合器在极端工况下的承载能力并延长其使用寿命,设计了一种结构简单、低副替代高副的新型螺旋超越离合器。考虑自锁及解楔、最小弹簧预紧力、耐磨性和强度等约束条件,对螺旋超越离合器进行了结构设计。进一步,针对实际工况建立了离合器动力学仿真模型,对启动接合和差速接合2种工况进行了仿真分析,对比分析了内外环与中介环摩擦系数及螺纹升角等关键参数对离合器差速接合性能的影响。研究结果表明,所设计的螺旋超越离合器具有较好的接合性能;差速接合时冲击扭矩较启动接合时大(约2倍的额定扭矩),实际使用中可优先选用启动接合;螺纹升角对螺旋超越离合器差速接合冲击扭矩影响较大,内外环与中介环摩擦系数大小对离合器接合时间影响较大,为螺旋超越离合器的应用提供了一种可行的技术方案。

Abstract: In order to further improve the bearing capacity of the overrunning clutch under extreme conditions and prolong its service life,a new type of spiral overrunning clutch with simple structure and low pair instead of high pair was designed. Considering the constraints of self-locking and de-wedge,minimum spring preload,wear resistance and strength,the structural design of the spiral overrunning clutch was carried out. Further,the clutch dynamics simulation model was established for the actual working conditions,and the two working conditions of start-up engagement and differential engagement were simulated and analyzed. The influence of key parameters such as the friction coefficient between the inner and outer rings and the intermediate ring and the thread angle on the differential engagement performance of the clutch was compared and analyzed. The results show that the designed spiral overrunning clutch has good engagement performance ;the impact torque during differential engagement is larger than that during start-up engagement (approximately 2 times the rated torque),and start-up engagement can be preferentially selected in practical use. The thread angle has a great influence on the impact torque of the differential engagement of the spiral overrunning clutch,and the friction coefficient between the inner and outer rings and the intermediate ring has a great influence on the engagement time of the clutch,which provides a feasible technical scheme for the application of the spiral overrunning clutch.

Key words: spiral overrunning clutch, structural design, dynamics, engagement performance, impact torque
