摘要
对MS-800四球摩擦磨损试验机进行了改造,加装了调速系统,使得原有试验机可在改变转速条件下工作,模拟不同的速度工况;加装了数据采集系统,可实现对润滑油摩擦系数准确、快速的测试;推导了用四球机测试润滑油摩擦系数的公式。
MS-800 four-ball tester had been improved, speed control system had been fixed, which made four-ball tester work at different speed and simulate different condition; data acquisition system had been fixed, the test of friction coefficient of lubricating oil became accurate and fast; the formula for calculating friction coefficient of lubricating oil tested with four-ball tester, had been derived.
