摘要

研究了动态间隙和转速对时变啮合刚度的六自由度齿轮-轴承系统模型的影响。动态侧隙与中心距之间的关系可以明确定义。用Newmark-β方法求解了模型的非线性微分方程。结果表明，系统振幅随转速的增加而增大。在达到一定转速后，系统由周期运动跳到混沌运动，有效幅值发生剧烈变化。动态侧隙与固定侧隙相比，动态侧隙的幅值增大，频率分量多样化。随着转速的增加，系统的振动位移随着动隙的增大而增大，系统的混沌行为变得复杂。数值结果为工程人员选择稳定运行的转速段提供了有益的参考。

Dynamic Characteristics of Spur Gear Pair with Dynamic Center Distance and Backlash

Effect of dynamic backlash and rotational speed is investigated on the six-degree-of-freedom model of the gear-bearing system with the time-varying meshing stiffness. The relationship between dynamic backlash and center distance can be defined clearly. The nonlinear differential equations of the model are solved by the Newmark-β method. The results show that system amplitude increases in the wake of increasing rotational speed. After reaching a certain rotational speed, the system jumps from periodic motion to chaos motion, and the effective amplitude is changed violently. Comparing the dynamic backlash with fixed backlash, the amplitude of the dynamic backlash is augmented and the frequency components are diversified. The vibration displacement is enlarged by the dynamic backlash and the chaotic behavior of the system becomes complex with increasing rotational speed. The numerical results provide a useful reference source for engineers to select rotational speed section for steady running.

期刊介绍： This comprehensive journal provides the latest information on rotating machines and machine elements. This technology has become essential to many industrial processes, including gas-, steam-, water-, or wind-driven turbines at power generation systems, and in food processing, automobile and airplane engines, heating, refrigeration, air conditioning, and chemical or petroleum refining. In spite of the importance of rotating machinery and the huge financial resources involved in the industry, only a few publications distribute research and development information on the prime movers. This journal is the first source to combine the technology, as it applies to all of these specialties, previously scattered throughout literature.
