THEORETICAL CALCULATION AND EXPERIMENTAL TESTING OF IMPROVED BELT TRANSMISSION FOR COTTON CLEANING MACHINES

Abstract

The article considers the object of belt transmission driving all the drums of the USK cotton-cleaning unit, most commonly used in the cleaning shop of cotton-cleaning plants, and theoretically calculates the improved design of belt transmission consisting of two pulleys and a belt. Traction power of belt and belt transmission according to experimental methods is characterized by dependence of belt relative slip and effi ciency on transmission resistance coeffi cient. A mathematical model of new belt transmission design has been developed, which allows theoretical estimating of belt tensile strength and rational operating mode in elastic slipping zone; the design has been installed at the machinery of the cotton-cleaning plant, a part of unitary enterprise “Real Agro Cotton”. The results of the experiment were analyzed
