Abstract

The basic objective of this research is to develop an inexpensive, multipurpose and efficient test rig for condition monitoring of rolling element bearings. The fundamental philosophy of measurement of lubricant film thickness for monitoring the condition of rolling element bearings has been exploited and transformed in the form of a test rig. The developed test rig is potent enough for performance evaluation and condition monitoring of rolling element bearings which is vital for its prolonged life and enhanced performance. A significantly correct prediction of life of bearing can also be made which in turn gives an idea about possible mode and time of failure. Certain machineries like aircraft, battle tanks, rocket launchers, ships, etc. need impeccable working of the system. Failure of such systems is not acceptable at any cost. In the heart of such system, bearings play a central and key role. Still there is no such standard mechanism available for ascertainment of performance and testing of rolling element bearings with high degree of reliability. In the continuing process of improvement and modification in the existing test rig, a simple, versatile, and inexpensive test rig has been developed and presented through this paper.

Key words: Condition monitoring, low cost, lubricant film thickness, performance evaluation, rolling element bearing, test rig.
