With the rapid development of economy in our country, the development of the synchronous belt is mature, it also marks the application field of synchronous belt is more and more widely, more and more attention by all walks of life. But it also brings the new thinking, including synchronous belt in the optimization of design how to use more? The development of new materials? And the development of the related equipment and so on have brought new challenges. First of all, only have a comprehensive knowledge of the advantages of his ability to improve it. Compared with other similar products, synchronous belt noise is relatively small, it does not require any lubrication measures, also can is the rotation of the machine is fast and efficient. And the synchronous belt only need a small space to install it, it is of great advantage, the adaptability to environment is quite strong. Like other kinds of engine, will be limited in the installation space, demand is more, the diversity of the function of synchronous belt is easy to implement. Visible, its advantage is obvious. With his good points, people can clearly realize that, although said advantages are obvious, but there are also some disadvantages. Like a synchronous belt is easy to access to the engine oil and some other chemical products the opportunity to compare, combined with the cause of the heat, rubber material will be aging phenomenon, synchronous belt will appear crack, deformation, even serious will appear rupture phenomenon. So in the face of some of the pitfalls of these may lead to serious consequences, to his improvement is also more and more important, more urgent thing. Any things are two sides to everything, and synchronous belt are no exception. In the show excellent performance, we also want to do good foster strengths and circumvent weaknesses, but we also cannot ignore the problems existing in the synchronous belt, want to have a better solution to solve, such ability can have a bigger development space.
