Mechanical design transmission V-belt structure
The cross-section structure of an ordinary V-belt consists of a top rubber (tensile layer), a tensile body (strong layer), a bottom rubber (compression layer), and a wrapping layer (as shown in Figure 7-4). When the belt around the pulley, the top layer of rubber is stretched and elongated, so called tensile layer; bottom layer of rubber is shortened by pressure, so called compression layer. Covering layer made of rubber canvas, used to protect the V-belt; tension layer and compression layer are made of rubber; strong layer is divided into cord fabric core structure (Figure 7-4 (a)) and rope core structure (Figure 7-4 (b)) two kinds. V-belts with cord fabric core structure are easy to manufacture and have good tensile strength, while V-belts with rope core structure have good flexibility and high bending strength, and are suitable for applications with small pulley diameters and high rotational speeds. Narrow V-belt (Figure 7-4(c)) is a new type of V-belt using polyester and other synthetic fibers as the strong layer. Compared with ordinary V-belts, when the height h is the same, the top width b of narrow V-belts can be reduced by about 1/3, and its top is in the shape of a bow and the side (working surface) is in the shape of a concave curve, so the load carrying capacity is significantly higher than that of ordinary V-belts, and it is suitable for transmitting high power and requiring a compact structure.
