行星轮偏心误差对行星齿轮传动系统均载性能的影响
Study on the Influence Rules of Planetary Gear Eccentric Errors on Dynamic Load Sharing Behavior of a Planetary Gear Train
摘要:
本文基于行星齿轮传动系统弯扭耦合非线性动力学模型,采用数值仿真的手段,研究了行星轮偏心误差对行星齿轮传动系统均载性能的影响规律。研究结果发现,在各行星轮偏心量一致的条件下,行星齿轮传动系统的行星轮偏心量存在一个误差阀值,当偏心量在小于该阀值的区间内变化时,行星齿轮传动系统的均载性能没有明显变化;当偏心量在大于该阀值的区间内增大时,行星齿轮传动系统的均载性能会显著降低。
Abstract:
By using the method of numerical simulation, the influence rules of planetary gear eccentric errors on dynamic load sharing behavior of a planetary gear train are studied based on a nonlinear lateral-torsional vibration model. Under the assumption that all of the planetary gears have the same eccentric errors, planetary gear train has a threshold value error; the dynamic load sharing behavior of the system will remain unchanged with the eccentric error of planetary gears changing under the threshold value error; the dynamic load sharing behavior of the system will worsen significantly with the eccentric error of planetary gears increase above the threshold value error.
