Mechanical Characterisation of the Coated Roller Bearing

Abstract

Due to increase demand of rotating elements in various fields of mechanical, electronics and fluid industry there is a need for moving elements like rolling bearings. Since the supporting member is rolling bearings hence in this work we are trying to improve the performance by studying the structure of the material present in the bearing, type of optimised coating i.e by polytetra fluroethylene coating.coating an optimum layer of 0.05mm thickness and checking the performance at different speeds and various load conditions is examined .the surface topography after coating is checked using sem technique and the discussions are made. Comparison of different types of bio grease for the coated bearing material. Capturing these vibrations of the bearing using vibrometers and accelerometers and improving the remaining useful life of the bearing by changing the type of coating material.
