Abstract: The contained gear rig which is a pandimensional power flow type was successfully improved and developed into a new gear rig and measurement system which has advantages of high precision and complete test method. Using this kind of gear rack the following properties of the 00# semi-fluid lubricant were evaluated compared with 50# mechanical oil, i.e., the voltage of oil film between occlusion face, the efficiency of gear transmission, the vibration and noise of the decelerator,the temperature rising and anti-wear property of lubricant, etc. The results show that the analytical results on lubricating properties of semi-fluid lubricant are reliable. This gear rig can be used as the pandimensional test rig for determing lubricating performances of semi-fluid lubricant.
