Experimental Setup Using Rotating Circular Disc for Kinetic Coefficient of Friction Using Lubricants

Abstract

Friction plays an important role in maintaining the contact between two surfaces while transmitting power. If the friction value goes down highly then the power transmission will not be done in effective manner. Similarly, if the frictional forces go very high then also high amount of energy will be dissipated in the form of heat, resulting into concentration of thermal stresses. So, while designing them we need to concentrate on the study of tribology. The system is integrated with electronics for direct value calculation. Using different types of lubricants, having different properties helps in behavior of different lubricants for different conditions and speed. Here we find the kinetic coefficient of friction using friction tester between two surfaces using a rotating disc and spherical ball. Due to this tester we can compare different lubricants and their working at different speeds. Also, it is useful in study of tribology in which other than coefficient of friction we can also investigate behavior of materials and wear in between two surfaces consisting lubricant. Previously, the tester uses to determine dry coefficient of friction and mainly static coefficient of friction but this setup ensures the wet friction.
