Dynamic performances of mine equipment transmission system based on ADAMS
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.
