以单级滑动轴承支撑的齿轮系统为研究对象，建立系统数学模型，理论计算系统在不同滑动轴承间隙下的振动特性；搭建齿轮-滑动轴承试验台，通过更换轴承的方式测试不同轴承间隙下齿轮系统的振动参数。实验测试与理论计算所得结果趋势一致，表明负载一定时增大滑动轴承间隙会使得齿轮系统振动加剧，增加负载转矩也会使得齿轮系统的振动加剧。
Based on the single-stage gear system supported by sliding bearings, a mathematical model of the system was established, the vibration characteristics of the system under different sliding bearing clearances were calculated theoretically, a gear-sliding bearing test bench was set up, and the vibration parameters of the gear system under different bearing clearances were tested by changing the bearings. The experimental test is consistent with the trend of theoretical calculation, which shows that increasing the sliding bearing clearance at certain times will increase the vibration of the gear system, and increasing the load torque will also increase the vibration of the gear system.
