Abstract

A V-belt transmission system includes a small pulley (2) and a large pulley (1). A V-belt (3) winds around the large pulley (1) and the small pulley (2). The V-belt (3) is in friction transmission with the large pulley (1). The transmission between the V-belt (3) and the small pulley (2) is a composite transmission combining the friction transmission with the mesh transmission. The invention provides a V-belt composite transmission system which can effectively avoid the occurrence of slippage, improve the transmission efficiency, reduce the distortion of the belts, and prolong the service life of the belts, thus addressing the problem of the slippage and idle rotation of the existing belt transmissions.

Abstract

A design method for a V-belt(2) and a pulley(1) is provided, which comprises the following steps: 1) concavo-convex teeth are designed on the bottom of the groove of the pulley (1) provided with a V shape groove; 2) concavo-convex teeth in mesh with the teeth of the pulley(1) are designed on the inner radial surface of the V-belt(2); 3) the belt (2) is meshed with the pulley (1) in operating state in the drawing, and the interference part between the concavo-convex teeth of the belt and the pulley will emerge on the transition part between the wrap angle part and the straight part of the belt; 4) narrowing the tooth, shortening the tooth in radial direction, or eliminating the tooth is used to solve the interference problem of the convex teeth. Usually, the driving between the V-belt (2) and the pulley (1) depends on the friction of the V surfaces, and meshing driving is supplemented when needed.

Abstract

A V-belt (1), a pulley (2) and a driving manner thereof. Concavo-convex teeth (4-1) designed by meshing transmission theory are formed on the inner surface of the V-belt (1), the pulley is provided with a V-shape groove(3), concavo-convex teeth (4-2) designed by meshing transmission theory are formed on the bottom of the V-shape groove(3). In general, the driving between the V-belt (1) and the pulley (2) depends on the friction of the V surfaces, meshing driving is supplemented when skidding occurred between the V-belt (1) and the pulley(2).
