1. Ordinary V-belt: the structural bearing layer is rope core or rubber curtain step, wedge angle is 40 degrees, relative height is close to 0.7, trapezoid section ring belt, with large equivalent friction factor, good adhesion between working surface and wheel groove, small allowable enveloping angle, large transmission ratio, small preload, soft rope core structure belt, good bending fatigue
2. Narrow V-belt: the structural bearing layer is rope core, wedge angle is 40 degrees, relative height is close to 0.9, trapezoidal section ring belt, besides the characteristics of ordinary V-belt, it can bear large preload, high allowable speed and bending times, high transmission power, energy saving
3. Joint V-belts: the structure of several ordinary V-belts or narrow V-belts is bonded equidistant with rubber cord, and 2, 3, 4 or 5 are connected into a group. The load of each V-belt is uniform, which can reduce the vibration and cross rotation in operation, and the structure is compact, and the transmission with high requirements is required
4. V-belt of automobile: V-belt with rope core on the bearing layer, with a relative height of 0.9 and 0.7, good flexibility and heat resistance. V-belts for internal combustion engines such as automobiles and tractors can also be used for transmission with small spacing between pulley and shaft and high working temperature
5. V-belt with tooth shape: the bearing layer is a rope core structure, and the V-belt with tooth shape is made around the inner circle. It has good heat dissipation and good adhesion with the wheel groove, and is the best V-belt with curved flexibility
6. V belt with large inclination: the bearing layer is rope core, wedge angle is 60 degree polyurethane ring belt, with uniform quality, high friction factor, high transmission power, small wear resistance of external dimension, good oil resistance, high speed, and extremely compact structure
7. Wide V-belt: the ring belt with trapezoidal section with a load layer of rope core and a relative height of 0.3 is good in flexibility, heat resistance and pressure resistance, and transmission with no extreme speed change
8. Multi carrying: under the body of the flat belt with rope core structure, there are ring belts with non dry longitudinal triangle wedge. The working surface is wedge surface, which has two types of rubber and polyurethane, which has the characteristics of soft flat belt and large friction force of V belt. It is more stable than V-belt transmission, small in outline and compact in structure, especially for transmission with more V-belt or vertical ground of axle
9. Double side V-belt: the cross section is hexagonal, the four sides are even working face, the bearing layer is rope core, which is located in the center of the section. The working belt body of both sides is thick, the bending flexibility is poor, and the service life and efficiency are low
10. Round belt: simple structure section is round, with round belt, round rope belt, round cotton fiber belt, etc
