Experimental Investigation of Thermal Elasto-Hydrodynamic Lubrication Based on Temperature Control
The heat generated from the working tribo-pairs will make the temperature of the lubricant rise which deficiently affects the performance of the lubricant and make the lubricant film thinner or broken which is the main cause leading to the failure of mechanism parts and equipment.In order to study the performance of lubricants under different temperatures,an improved test rig for lubrication film thickness is developed based on classical ball-on-disc contact and the heating system and oil storage device are innovatively added to control the temperature.This paper proposes a new method for judging the interference order of contact center based on image process,which is convenient and accurate.A series of temperature tests are conducted on oil and grease.Results show that when load and speed are constant,temperature has a great effect on the central film thickness of both oil and grease.When temperature is below 60 ℃,the grease may not be completely melted,so the central film thickness is greatly affected by the speed and load,but when over 70 ℃,the grease has melted and become soften,and the change in the central film thickness tends to be relatively stable.
