The use of synchronous belt with the continuous development of our country mechanical industry and more extensively. At present, more and more people begin to connect to the synchronous belt transmission rate is low, low noise, no pollution, high stability and so on, and this also prompted the synchronous belt is widely used. Choosing a suitable synchronous belt will make our work more efficient, so how do we choose the synchronous belt? Below small make up for everybody simple introduction: first of all, we want to according to the use of their own needs, to choose the most suitable for their own synchronous belt. Such as requiring the transmission effect is higher, the transmission ratio is prepared, generally choose trapezoidal tooth synchronous belt. If is to reduce the wear between the belt and transfer is bigger, then selecting the circular arc toothed belt. If it is both accurate transmission ratio and durable life is long, you can choose rubber arc-gear synchronous belt. Second, in the choice of synchronous belt material, need to pay more attention. Because of synchronous belt material is affect the work quality of synchronous belt is a very important factor. But also according to our own needs to choose a different material. The lighter the weight of the aluminum alloy, for example, is mainly used in light load synchronous belt transmission. And s45C namely carbon quenched and tempered steel, has good wear resistance but heavy weight, it is mainly used for heavy synchronous belt, the force evenly. Finally want to remind everybody is, in the proper selection of synchronous belt is very important, don't be said that the synchronous belt with others is very good, so oneself also to buy this kind of synchronous belt, want to know only in line with their own is the best, the proper synchronous belt can not only make the highest production efficiency, people also will be more comfortable when in use.
