Development of a V-belt variator

Abstract

For stepless regulation of the operating speed of technological machines, in the ranges provided by the technology, it is recommended to use a V-belt variator. However, currently having V-belt variators with a special V-belt have significant disadvantages that reduce their effectiveness. In this regard, a V-belt variator with a standard drive V-belt is proposed, the driven pulley of which is divided into identical sectors, the diameter of the driven pulley is changed by synchronous movement of these sectors in radial directions. Studying a V-belt variator with a standard V-belt drive and a multi-sector driven pulley, the main parameters such as the number of sectors, the traction capacity of a multi-sector pulley, the diameters of a multi-sector pulley, the force of normal belt pressure on a multi-sector pulley, which are necessary when designing a variator, were determined.
