Experimental measurement of a pulling force and determination of a friction coefficient during driven transport rollers’ movement

Abstract

The paper presents an experimental measurement of a pulling force and determination of a friction coefficient during driven transport rollers’ movement in a continuous transport system. To implement an experimental measurement, a laboratory machine was designed, enabling an experimental detection of a friction coefficient during movement in the contact surface of the transported load and the roller casings. The values of friction coefficient were determined for three material types: wood, plastic and rubber against the acrylic paint sprayed on a steel roller’s casing. Experimental pulling force measurement with a tensometric load sensor was realized for three different angles of the roller conveyor’s inclination. The results made it possible to determine a mean value of friction coefficient during movement between the contact surfaces of the three materials and the coating of driven rollers casings. The results can be implemented to digitize and monitor operation of electric motor machines.
