What are the advantages of synchronous belt and
In the eyes of consumers, there is no difference between synchronous belt and chain drive, but this is a wrong view. There is a fundamental difference between synchronous belt and chain drive. And synchronization has the advantages that the chain drive can't match, so what are the advantages?
If you want to understand the advantages of synchronous belt and chain drive, you must first understand the two. The synchronous belt drive is generally composed of a driving wheel, a driven wheel and a transmission belt tightly sleeved on two wheels. The intermediate flexible part is used to transmit rotational movement and power between the main and driven shafts by friction. The timing belt is made of steel wire as the tensile body, outsourcing polyurethane or rubber. The cross-section is rectangular, the belt surface has an endless transmission belt with equidistant transverse teeth, and the synchronous pulley wheel surface is also made into a corresponding tooth shape. The transmission is achieved by the meshing between the teeth of the synchronous belt and the teeth of the synchronous belt wheel, and the two have no relative sliding, and the circumferential speed is synchronized, so it is called synchronous belt transmission. The chain drive is composed of a sprocket and an endless chain. The meshing between the teeth of the chain and the sprocket is actually driven by the same direction transmission between the parallel shafts. Compared with belt transmission, sprocket transmission has no elastic sliding and slippage, and can maintain an accurate average transmission ratio. It requires small tension and pressure on the shaft. It can reduce the friction loss of the bearing. It has a compact structure and can operate at high temperatures. , Work in harsh environments such as oil pollution; compared with the transmission gear, the manufacturing and installation accuracy is lower, and the transmission structure is simple when the center distance is large.
Synchronous belt transmission is composed of a closed ring belt with equidistant teeth on the inner peripheral surface and a pulley with corresponding teeth. During operation, the convex teeth of the belt mesh with the tooth grooves of the pulley to transmit movement and power. Compared with other transmission ratios, synchronous belt transmission has the following advantages. There is no slippage when working and accurate transmission ratio. 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 of not extending under the action of tension, it can maintain the belt joint The distance is constant, so that the belt and the tooth groove can be correctly meshed, and the synchronous transmission without slip is realized, and the accurate transmission ratio is obtained.
The transmission efficiency is high and the energy saving effect is good. Because the synchronous belt is a non-slip synchronous transmission, it has a higher transmission efficiency, which can generally reach 0.98. Compared with V-belt drive, it has obvious energy saving effect, which can be proved by the following examples. It can be seen from the above several examples that synchronous belt transmission has great potential for energy saving, so the use of synchronous belt transmission can obtain higher economic benefits.
