Why does synchronous belt play an irreplaceable role in the field of transmission?

In the field of industrial transmission, there is a product that is a necessary component. Many machines cannot operate without it. It is the synchronous belt. So have you ever thought about why the synchronous belt has been around for so long but has never been replaced by other products? The reason? Let the editor introduce to you the main reasons why the timing belt is not replaced.

Synchronous belt drive has the following advantages:

1. The synchronous belt has no slippage when working and has an accurate transmission ratio.

Synchronous belt drive is a kind of meshing drive. Although the synchronous belt is an elastic body, the load-bearing rope in it has the characteristic of not elongating under the action of tension, so the belt pitch can be kept unchanged, so that the belt and gear tooth grooves can be maintained. It can mesh correctly to achieve slip-free synchronous transmission and obtain accurate transmission ratio.

2. The synchronous belt has high transmission efficiency and good energy saving effect.

Since the synchronous belt is used for non-slip synchronous transmission, it has a high transmission efficiency, generally up to 0.98. Compared with V-belt transmission, it has obvious energy-saving effect, which can be proved by the following examples.

From the above examples, we can see that synchronous belt drive has great potential in energy saving, so using synchronous belt drive can achieve higher economic benefits.

3. The synchronous belt transmission ratio range is large and the structure is compact.

The transmission ratio of synchronous belt transmission can generally reach about 10, and in the case of large transmission ratio, its structure is more compact than V-belt transmission. Because the synchronous belt drive is a meshing drive, its pulley diameter is much smaller than the V-belt pulley that relies on friction to transmit power. In addition, because the synchronous belt does not require large tension, the size of the pulley shaft and bearings can be reduce. 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 has low operating costs.

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 length is very small during operation, and there is no need to adjust the tension frequently like V-belts, chains, etc. In addition, the synchronous belt does not require any lubrication during operation, so maintenance is very convenient, and the operating cost is much lower than V-belts, chains, and gears.

5. The synchronous belt can work normally under harsh environmental conditions.

Under harsh working conditions with dust, impurities, water and corrosive media, the chain is prone to rust and wear, and the V-belt will slip, but the synchronous belt drive can adapt to these conditions. Because it is a meshing transmission, it will not slip in the presence of rain, and water is a good lubricant for rubber, which can reduce belt wear. When there is dust and impurities, when the synchronous belt teeth enter the pulley groove, the teeth will squeeze the air originally left in the pulley groove, causing the pressurized air to be discharged to both sides of the pulley groove. This air extrusion will At the same time, it plays the role of cleaning the meshing surface and taking away dust and impurities, thereby reducing the wear of the timing belt. In addition, the synchronous belt has high corrosion resistance and heat resistance, and can still work normally under high temperatures and corrosive gases.
