摘　　要：推土机终传动装配完成后须进行空运转试验,同时还要对终传动内部壳体及啮合部分进行清洗,为后续的装机运行提供必要保障。推土机终传动试验研制试验台液压系统设计时采用了试验用油净化方案,在实现终传动空运转试验功能的同时,还具有高效充分冲洗及油液循环再利用的特点,提高了终传动的清洗效果,节约了试验成本,延长了油液的使用寿命。After final drive of bulldozer is assembled,non-load testing must be carried out.At the same time,the internal shell and meshing parts of final drive must be cleaned to provide necessary guarantee for subsequent installation and operation.The design of hydraulic system of test bench for bulldozer final drive test adopts purification scheme of test oil.While realizing non-load testing function of final drive,it also has the characteristics of efficient and full flushing and oil recycling,which improves cleaning effect of final drive,saves test cost and prolongs service life of oil.
