摘　　要：在煤矿井下实现变速、变矩的动力头是钻机的重要零部件之一,其减速箱的内部激励主要包括齿轮副的时变啮合刚度、综合啮合误差;外部激励主要包括原动机的扭矩波动以及负载的扭矩变化激励。在综合研究了内部激励和外部激励基础上,获得了ZYWL-2000G动力头内部激励力图和外部激励力图。可为研究动力头在动态激励下的响应和对动力头的进一步优化设计提供了一定的理论基础。The power head for achieving variable speed and torque conversion in coal mine is one of the important parts of the drilling rig.The internal excitation of the reducer mainly includes the time-varying meshing stiffness of the gear pair and the comprehensive meshing error;The external excitation mainly includes the torque fluctuation of the prime mover and the torque variation excitation of the load drilling tool.Based on the comprehensive study of internal and external excitation,the internal and external excitation diagram of ZYWL-2000G power head were obtained.It provides a theoretical basis for the optimization design of the gearbox of this series of drilling rig.
