Summary of advantages and disadvantages of synchronous belt drive

1. The synchronous belt works without slipping and has an accurate transmission ratio

The synchronous belt transmission is a kind of meshing transmission. Although the synchronous belt is an elastic body, because the load-bearing rope in it has the characteristic that it does not elongate under the action of tension, it can keep the belt pitch unchanged, so that the belt and the tooth groove It can be meshed correctly to realize synchronous transmission without slip and obtain precise transmission ratio.

2. The transmission efficiency of the synchronous belt is high, and the energy saving effect is good

Since the synchronous belt is used for synchronous transmission without slipping, it has a high transmission efficiency, generally up to 0.98. Compared with V-belt transmission, it has obvious energy-saving effect.

3. Synchronous belt transmission ratio range is large, compact structure

The transmission ratio of the synchronous belt drive can generally reach about 10, and in the case of a large transmission ratio, its structure is more compact than that of the V-belt drive. Because the synchronous belt transmission is a meshing transmission, the diameter of the pulley is much smaller than that of the V-belt pulley that relies on friction to transmit power. In addition, since the synchronous belt does not require a large tension force, the size of the pulley shaft and the bearing can be adjusted. decrease. Therefore, compared with the V-belt drive, under the same transmission ratio, the synchronous belt drive has a more compact structure.

4. The synchronous belt is easy to maintain and the operating cost is low

Because the load-bearing rope in the synchronous belt is made of materials such as glass fiber and steel wire with very small elongation, the belt elongates very little during operation, and there is no need to frequently adjust the tension like V-belts and chain drives. In addition, the timing belt does not need any lubrication during operation, so maintenance is very convenient, and the operating cost is much lower than that of V-belts, chains, and gears.

5. The timing belt can still work normally under harsh environmental conditions

Although the synchronous belt transmission has the above advantages compared with other transmissions, it has extremely strict requirements on the center distance during installation, and at the same time, the manufacturing process is complicated and the manufacturing cost is high.
