The advantages and disadvantages of synchronous belt drive are summarized as follows:

　　1. 同步帶工作時(shí)無滑動(dòng)，傳動(dòng)比準(zhǔn)確

　　1. There is no sliding when the synchronous belt works, and the transmission ratio is accurate

　　同步帶傳動(dòng)是一種嚙合傳動(dòng)。雖然同步帶是一個(gè)彈性體,軸承繩軸承負(fù)載的特點(diǎn)沒有拉伸張力的作用下,所以帶間距可以保持不變,這樣可以編織皮帶和齒輪槽正確,實(shí)現(xiàn)同步驅(qū)動(dòng)沒有滑動(dòng),獲得準(zhǔn)確的傳動(dòng)比。

　　Synchronous belt drive is a kind of meshing drive. Although the synchronous belt is an elastic body, the bearing load characteristics of the bearing rope are not affected by the tensile tension, so the belt spacing can be kept unchanged, so that the belt and gear groove can be woven correctly, the synchronous drive can be realized without sliding, and the accurate transmission ratio can be obtained.

　　同步帶傳動(dòng)的優(yōu)缺點(diǎn)概述

　　Advantages and disadvantages of synchronous belt drive

　　2. 同步帶傳動(dòng)效率高，效果好

　　2. High transmission efficiency of synchronous belt and good energy saving effect

　　由于同步帶作為無滑動(dòng)同步傳動(dòng)，它具有較高的傳動(dòng)效率，一般可達(dá)0.98。與三角皮帶傳動(dòng)相比，效果明顯。

　　As a non sliding synchronous transmission, the synchronous belt has a high transmission efficiency, generally up to 0.98. Compared with V-belt drive, the energy saving effect is obvious.

　　3.同步帶傳動(dòng)比大，結(jié)構(gòu)緊湊

　　3. Large transmission ratio and compact structure of synchronous belt

　　同步帶的傳動(dòng)比一般可達(dá)l0左右，在傳動(dòng)比較大的情況下，其結(jié)構(gòu)比三角皮帶傳動(dòng)更緊湊。由于同步帶傳動(dòng)是嚙合傳動(dòng)，所以同步帶輪的直徑遠(yuǎn)小于依靠摩擦力傳遞動(dòng)力的三角帶輪。另外，由于同步帶不需要很大的張力，所以可以減小帶輪軸和軸承的尺寸。因此，與三角皮帶傳動(dòng)相比，在相同傳動(dòng)比下，同步帶傳動(dòng)結(jié)構(gòu)相對緊湊。

　　The transmission ratio of synchronous belt can reach about l0 generally. In the case of large transmission ratio, its structure is more compact than that of V-belt. Because the synchronous belt drive is meshing drive, the diameter of the synchronous belt wheel is far smaller than the triangular belt wheel which depends on the friction force to transmit power. In addition, since the synchronous belt does not need much tension, the size of the belt axle and bearing can be reduced. Therefore, compared with the triangle belt drive, simultaneous interpreting belt transmission structure is relatively compact under the same transmission ratio.

　　4. 同步帶維護(hù)方便，運(yùn)行成本低

　　4. The synchronous belt is easy to maintain and low in operation cost

　　由于同步帶中的軸承繩是由玻璃纖維、鋼絲等材料制成，伸長率非常小，所以在運(yùn)行過程中，帶的伸長率非常小，不需要調(diào)節(jié)三角帶、鏈傳動(dòng)等張力。此外，同步帶在運(yùn)行中也不需要任何潤滑，所以維護(hù)非常方便，運(yùn)行成本遠(yuǎn)低于三角帶、鏈條、齒輪。

　　As the bearing rope in the synchronous belt is made of glass fiber, steel wire and other materials, the elongation is very small, so in the process of operation, the elongation of the belt is very small, and it is not necessary to adjust the tension of the triangle belt, chain drive and so on. In addition, the synchronous belt does not need any lubrication in operation, so the maintenance is very convenient, and the operation cost is far lower than the triangle belt, chain and gear.

　　5. 同步帶能在惡劣的環(huán)境條件下正常工作

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

　　雖然同步帶傳動(dòng)與其他傳動(dòng)相比具有上述優(yōu)點(diǎn)，但同步帶傳動(dòng)在安裝過程中對距的要求極為嚴(yán)格，同時(shí)制造工藝復(fù)雜，制造成本高。

　　Although the synchronous belt drive has the above advantages compared with other drives, the requirements for the center distance of the synchronous belt drive in the installation process are extremely strict, while the manufacturing process is complex and the manufacturing cost is high.
