摘要

为分析可控启动装置（CST）齿轮传动系统在变载工况下的动态响应特性,以重型刮板输送机变载工况为例,建立了齿轮传动系统虚拟样机模型,开展其动力学仿真分析,得到齿轮动态啮合力、行星轮振动响应和轴承动态载荷。结果表明,齿轮啮合力的动态变化与实际齿轮传动的轮齿啮合力变化情况一致;行星轮的动态响应表现了齿轮系统的扭转振动情况;轴承支反力受齿轮啮合力的影响,二者动态变化相同。通过对CST齿轮箱进行变载工况试验,所得齿轮啮合频率与仿真结果相近,验证了模型的正确性,仿真结果可为CST齿轮传动系统的动态性能优化设计提供理论依据。

Abstract

In order to analyze the dynamic characteristics of gear transmission system in the controlled starting transmission（ CST）,taking the heavy scraper conveyor under varying load working condition as example,a virtual prototype of the system is established and dynamics simulation is carried out,the dynamic meshing force of gears,vibration response of planetary gear and dynamic loads of each bear point are obtained. The simulation results demonstrate that dynamic changes of gear meshing forces can match up with actual gear transmission,the dynamic response of planetary gear reflect the vibration situation of system,the dynamic loads of bear point are affected by the meshing force,the dynamic changes are same. The experiment of CST under varying load working condition is carried out,the test data of meshing frequency is close to the results of simulation which is validated the accuracy of the virtual prototype,besides,the results provide the theory basis for the dynamic performance optimization of CST gear transmission.
