Research And Development Of A Testing Bed For Mill Lubrication Oil Film Bearing

The oil film bearing is a kind of sliding bearing which employ lubrication oil as lubricant, and it is widely adopted in production of wire. In particular, the finishing mill group should bear high-speed, high-load, and hard to be polluted in harsh environment. While, college and domestic enterprises have carried out a large amount of research work about sliding bearing test bed currently, most of them can’t be used to do oil medium experiments.The thesis is mainly about the design of oil film testing bed, which is used to test the performance of the lubricant by simulating the working condition of the finishing mill group. The testing bed evaluates the quality of the lubrication oil mainly by measuring the temperature and the thickness of oil film, which based on a series of contrast tests.The purpose of this topic research is mainly about to put forward the solution to research on the performance study about some lubrication oil which includes a little amount of water. This thesis mainly completes the overall scheme design of the testing bed, which include mechanical and electrical drive system, lubrication system, loading system and monitoring and control system. Among them, the mechanical and electrical drive system adopt a spindle drive motor as power, which can provide6000rated speed; and chose three integrated oil film bearings as test and support bearing; the lubrication system use two separate lubrication systems and use temperature sensors to record the oil rise of temperature; the loading system use hydraulic loading to achieve the radial150kN; monitoring and control system use IPC, associated data acquisition card and a lot of sensors to measure and record some lubricant parameters.
