Classification of V-Belts

(1) Narrow and Wide V-belts

The aspect ratio of ordinary V-belts is 1: 1.5 to 1.6, while the narrow and wide V-belts are 1: 1.2 and 1: 2 respectively. The structural size of the narrow V-belt can be reduced by about 50% compared with the ordinary V-belt, which can save a lot of raw materials, and at the same time, the strength is uniform, the effective contact area is large, and the bending stress is small, which can greatly prolong the service life. The transmission efficiency of the narrow v-belt can reach 90% to 97%, the limit speed can reach 40-50m/s, and the transmission capacity is increased by 0.5 to 1.5 times. speed change belt. Its characteristic is that the upper and lower surfaces of the belt are mostly made into a single-sided or double-sided arc or tooth shape, which makes it easy to adjust the speed. It is mainly used in low-speed conical and disc-type continuously variable transmissions.

(2) Small Angle and Large Angle Triangle Belt

The main difference between it and the ordinary V-belt is that the angle 40 is changed to about 30 and 60. The small-angle V-belt can reduce the contact surface, reduce the required tension, and prolong the service life. It is suitable for small tension transmission of equipment. The large-angle V-belt is a hexagonal belt with a rectangular upper half and an inverted trapezoidal lower half, which can reduce friction loss, increase bearing capacity, and has a soft belt body, which is suitable for high-speed transmission of light and small equipment.
