Study Performance on AL-SI Alloy Bearing with SAE20W40 as Lubricants in Constant Speed and Varying Load Condition

In this present work an attempt is made to study the pressure distribution of Aluminium-Silicon alloy as bearing material and also load carrying capacity is evaluated ,From the results obtain it has been observed that, the maximum pressure distribution is obtained for SAE20W40 grade oil with constant speed varying load condition. So in the present work it has been selected to carry out the study on performance of the Aluminium-Silicon alloy bearing by considering the SAE20W40 grade lubricating oils as lubricating mediums and study has been carried out to find out the maximum pressure distribution by using a journal bearing test rig The Al-Si alloy as test bearing and test lubricating oils SAE20W40 is run at constant speed and varying load conditions (Example; 150N, 300rpm). It is made to run for 1hour to take maximum pressure value at angular rotation of 180̊. Sensor mounted on the bellow of the housing which gives the pressure readings and the data are transferred to the WINDOWS DUCOM 2010 software, extract condition of the bearings and gives the pressure distribution graphs as shown outcomes. Observe that pressure distribution is very less in 300 rpm with 150 N load is 75 Kpa and maximum pressure distribution is at 700 Rpm with load capacity 700 N is 1738 Kpa.
