摘要
为提高矿山装备传动系统的动态可靠性,基于ADAMS建立了二级行星传动系统啮合接触动力学模型,分析了各级齿轮的运动特性及啮合力,讨论了牵引转速及负载转矩对传动系统稳定性及轮齿均载特性的影响规律.结果表明,一级行星轮系相对二级行星轮系的传动稳定性更差、偏载更严重;随着负载增大,一级行星轮的速度波动加剧、均载性能减弱,二级行星轮的均载性能轻微改善;随着转速的增加,两级行星轮的速度波动均加剧,中心轮的速度波动降低,一级行星轮内啮合的均载性能相对改善.该结果为揭示矿山装备传动系统故障机制、优化其传动性能提供了参考.
Abstract
To improve the dynamic reliability of the transmission system in mine equipment,the meshing dynamic model was established based on ADAMS,the kinematic characteristics and meshing force of the gears were analyzed,and the influence of the speed and load on the transmission stability and the load sharing characteristics of the planetary gear was discussed.The results show that the transmission stability of the first stage planetary gear train is worse and the eccentric load is more serious than that of the second stage planetary gear train.Besides,with the increase of load,the speed fluctuation of the first stage planetary gear intensifies and the load sharing performance weakens,but the load sharing performance of the second stage planetary gear is slightly improved.Furthermore,with the increase of rotating speed,the speed fluctuation of the planetary gear intensifies but that of the central gear reduces,and the load sharing performance of the internal mesh of the first stage planetary gear is improved.The results provide a reference for revealing the fault mechanism and optimizing its transmission performance of the transmission system of mine equipment.
