摘　　要：为了分析盾构机主驱动减速器行星齿轮传动润滑特性,采用移动粒子半隐式(Moving Particle Semi-implicit,MPS)法建立了单级行星轮系飞溅润滑仿真模型。通过对比分析不同工况下行星轮系运动过程中的系统内部润滑油液粒子分布、速度场、压力场、轮齿啮合区域油液粒子数量及各旋转部件所产生的搅油阻力矩,研究了输入转速、初始油位高度以及油温对系统润滑效果与搅油损耗功率的影响。结果发现,油液粒子速度与压力随减速器的输入转速和油位高度的增加而增大,转速和油位过低将导致减速器内油液粒子分布不均匀;行星轮与太阳轮、内齿圈啮合区粒子数随输入转速和油温增加而减少,随油位高度降低而减少,其中,太阳轮啮合区为润滑不良风险区;系统搅油损耗功率受输入转速的影响最为显著,随转速的增加呈指数上升趋势,油位高度与油温的影响相对较小;在各工况下,3个行星轮产生的搅油损耗功率在总的搅油损耗功率中占比最大。In order to analyze the lubrication characteristics of the planetary gear transmission of shield main drive reducers,a simulation model of splash lubrication of the single-stage planetary gear train is established using the moving particle semi-implicit(MPS)method.By comparing the distribution of lubricating oil particles,velocity field,pressure field,the number of lubricating oil particles in the meshing area of gear teeth and the churning resistance moment produced by each rotating part during the planetary gear train movement under different working conditions,the influence of input speed,initial oil level height and oil temperature on the system lubrication effect and churning loss power are studied.The results show that the oil particle velocity and pressure increase with the increase of the input speed and oil level,and the low speed and oil level height will lead to the uneven distribution of oil particles in the reducer.The number of particles in the meshing zone between planetary gears,sun gears and inner gear rings decreases with the increase of input speed and oil temperature,and decreases with the decrease of oil level height.The meshing area of sun gears is the risk area of poor lubrication.The power loss of the system is most significantly affected by the input speed,and increases exponentially with the increase of the speed,while the influence of oil level height and oil temperature is relatively small.In each working condition,the churning loss power generated by the three planetary gears takes the largest proportion in the total churning loss power.
