1. There is no sliding when working, and there is an accurate transmission ratio

The double-sided toothed synchronous belt drive is a meshing drive. Although the synchronous belt is an elastic body, because the load-bearing rope in it does not stretch under tension, it can keep the belt pitch constant. The belt and the tooth groove of the wheel can be correctly meshed to achieve a synchronous transmission without slip and obtain a precise transmission ratio.

2. High transmission efficiency and good energy saving effect

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

From the above several examples, it can be seen that synchronous belt transmission has great potential for energy saving, so the use of synchronous belt transmission can obtain higher economic benefits.

3. Large transmission ratio range and compact structure

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

4. Convenient maintenance and low operating cost

Because the load-bearing rope in the double-sided toothed synchronous belt is made of glass fiber, steel wire and other materials with low elongation, the belt length is very small during operation, and there is no need to adjust the tension frequently like the V-belt and chain Tightness. In addition, the timing belt does not require any lubrication during operation, so maintenance is very convenient, and the operating cost is much lower than that of the V-belt, chain, and gear.

5. It can work normally under harsh environmental conditions

Under severe working conditions with dust, impurities, water and corrosive media, the chain is easy 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, because the belt teeth of the timing belt enter the pulley groove, the belt teeth will squeeze the air left in the groove, and the compressed air will be discharged to both sides of the groove. At the same time, it can clean the meshing surface and take 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 temperature and corrosive gas.
