Flat belt, V-belt and synchronous belt are three common transmission belt types, they have obvious differences in transmission principle, structural characteristics and application fields.
1. The difference between the working principle of transmission:
- Flat belt drive: The flat belt is tightly set on the smooth wheel face when driving, mainly relying on the friction between the belt and the wheel face to transmit power.
-V belt drive: The V-belt is placed in the V-shaped groove of the pulley during transmission, and the power is transmitted by the friction between the belt and the groove wall.
- Synchronous belt drive: the teeth of the synchronous belt are engaged with the tooth shape of the belt wheel, and the power is transmitted through the mesh between the teeth and the teeth, ensuring the accurate transmission ratio.
2. Differences in structural characteristics:
- Flat belt drive: the structure is simple, but it is easy to slip.
-V belt drive: with good contact stability, less slippage, relatively stable transmission ratio, more stable operation.
- Synchronous belt drive: relatively compact structure, with good wear resistance.
3. Differences in application fields:
- Flat belt drive: usually suitable for occasions with a smaller transmission ratio, about 3.
-V belt drive: suitable for short center distance and large transmission ratio (about 7), can work well in vertical and inclined transmission systems.
- Synchronous belt drive: mainly used in the need for accurate transmission ratio, such as computer external equipment, film projectors, video recorders and textile machinery.
