Dynamic Analysis of Torque Limiter in Haulage Section of MG400/980-WD Coal Mining Machine
In order to further investigate the operating characteristics of the torque limiter of the haul-off section of coal mining machine,the torque limiter of the haul-off section of MG400/980-WD coal mining machine is taken as the object of study,and its simulation model is established by combining with the structure of the haul-off section of the torque limiter,and the conditions of the simulation analysis are determined on the basis of the force analysis,so as to carry out the kinetic analysis of the torque controller.In the process of dynamic analysis,we focus on the change of the velocity curves of the copper sleeve,inner elastic ring and outer elastic ring in the torque limiter,as well as the contact force and contact moment of the secondary planetary carrier and the copper sleeve,and the results show that the change characteristics of the above analysis indexes are basically convergent,which proves that the torque limiter has a better dynamic performance.Finally,the actual test further proves the practical application effect of the torque limiter.
