Aiming at the reciprocating motion existing in the space rolling bearing, the wear characteristics of the reciprocating friction of MoS2 were studied. The friction simulation between Fe–Ni–Cr substrate and MoS2 is simulated by mixing multiple potential functions. and came to the following conclusions: . such as gas and magnetic suspension . The vertical load, friction ball diameter and reciprocating movement frequency (friction speed) are selected as the experiment factors. The cutting tools was installed in the special designed fixture on a reciprocating movement wear test machine. The wear depth increases with the increase in the Z-load, ball diameter and frequency.Historical/Traditional Test Geometry. The classic work of Thurston 1, Martens 2, Stribeck 3 and Hersey 4 were done using a journal-bearing geometry, which possesses all of the above requirements (Figure 3). An instrumented journal-bearing test allows for evaluation of the friction over a range of relative velocities and/or loads. The variation of friction force between upper test specimen and nether test specimen is very complicated on the reciprocating wear tester. There are many factors exerting influence on it. Based on the bench test, a system is developed for measuring the variation of the friction force between upper and nether test-piece.
