Analysis of Belting Stiffness Transmission Impact on Rotating Mass Motion Law of Technological Machines

The aims of this research are to develop a new scheme of belt transmission with an integral driven pulley and tensioning roller as well as to determine the laws of motion for the main and bottom shafts of the sewing machine as they depend on the rigidity of the elastic elements of the driven belt pulley with justification of settings. The article describes a new diagram of a belt drive with a split driven pulley and eccentric tension roller. The laws of the driver masses’ motion of the sewing machine were obtained and analyzed.
