【摘要】：采用球盘试验机测定了4116航天润滑油在不同工况下的摩擦因数,尤其成功实现了高低温环境下的测试.应用正交试验设计方法,研究了滚动速度、滑动速度、最大工作压力和入口油温4个因素对润滑油摩擦特性的影响,并绘出各因素对摩擦因数的影响曲线.研究结果表明:滑动速度和滚动速度对摩擦因数有显著影响,入口油温和最大工作压力对摩擦因数影响不显著.摩擦因数随着滑动速度的增加而增加,但是增加的幅度随滑动速度的增加而逐渐减小;随着滚动速度的增加,摩擦因数迅速减小,当滚速高于20m/s时趋于稳定;入口油温低于0℃时,其对摩擦因数有较大影响;随最大工作压力的增加摩擦因数缓慢增加.
[Abstract]:The friction coefficient of 4116 spaceflight lubricating oil under different working conditions has been measured by using a ball disk tester, especially in the high and low temperature environment. The rolling speed and sliding speed have been studied by using the orthogonal test design method. The effects of the maximum working pressure and inlet oil temperature on the friction characteristics of lubricating oil are studied. The results show that the sliding speed and rolling speed have a significant effect on the friction coefficient. The influence of inlet oil temperature and maximum working pressure on the friction coefficient is not significant. The friction coefficient increases with the increase of sliding speed, but the increasing amplitude decreases gradually with the increase of sliding velocity, and with the increase of rolling speed, The friction coefficient decreases rapidly and tends to be stable when the rolling speed is higher than 20m/s. When the inlet oil temperature is lower than 0 鈩，
