Multi Wedge Belt

‌Multi-V belt‌, also known as multi-groove belt or multi-slot belt, is a kind of annular rubber transmission belt with flat belt as base and 40° trapezoidal wedges arranged on the inner surface at equal intervals. Its working surface is the side of the wedge. The structural characteristics of multi-V belt make it have the advantages of large transmission power, small vibration and smooth operation during transmission. It is particularly suitable for transmission occasions requiring more V-belts or the wheel axis is perpendicular to the ground.

1. The transmission power is large, and the transmission power is 30% higher than that of ordinary V-belts in the same space.
2. The belt body is thin and flexible, which is suitable for transmission with small pulley diameter and high-speed transmission. The belt speed can reach 40m/s:
3. The addition of short fiber reinforcement can withstand higher lateral pressure, increase the belt wedge pressure performance, and reduce deformation after force; and the structure is compact, the vibration is small, and the operation is smoother.
4. It has the characteristics of cold and heat resistance, oil resistance, corrosion resistance, bending resistance, wear resistance, aging resistance, small elongation in use, and long service life.

Synchronous pulley consists of a circular belt with evenly spaced teeth on its inner circumference and a correspondingly engaging pulley. It combines the advantages of belt drives, chain drives, and gear drives. During transmission, power is transferred through the meshing of the belt teeth with the pulley's tooth grooves.
Synchronous pulley offers precise transmission ratios, no slippage, and constant speed ratios, ensuring smooth operation, vibration absorption, low noise, a wide range of transmission ratios (up to 1:10), and allowable linear speeds of up to 50 m/s. It can transmit power from a few watts to hundreds of kilowatts. With high transmission efficiency, generally reaching 98%, it is compact, suitable for multi-shaft transmission, and requires no lubrication, making it pollution-free and ideal for environments where contamination is not allowed or where working conditions are harsh.
