1. Synchronized belt operation without sliding, accurate transmission ratio synchronous belt transmission is a meshing transmission, although the synchronous belt is an elastomer, but because the load-bearing rope has the characteristics of non-elongation under tension, it can adhere to the belt pitch unchanged, so that the belt and the gear slot can correctly mesh, complete synchronous transmission without slip, and obtain accurate transmission ratio.

2．同步帶傳動功率高，作用好 因為同步帶作無滑動的同步傳動，故有較高的傳動功率，一般可達0.98。它與三角帶傳動比較，有明顯的作用。

2. Synchronized belt drive has high power and good energy-saving effect. Because synchronous belt is a synchronous drive without sliding, it has high transmission power, generally up to 0.98. Compared with triangular belt drive, it has obvious energy saving effect.

3．同步帶傳動比規(guī)模大，結構緊湊 同步帶傳動的傳動比一般可到達l0左右，并且在大傳動比情況下，其結構比三角帶傳動緊湊。因為同步帶傳動是嚙合傳動，其帶輪直徑比依托摩 擦力來傳遞動力的三角帶帶輪要小得多，此外因為同步帶不需要大的張緊力，使帶輪軸和軸承的標準都可減小。所以與三角帶傳動比較，在相同的傳 動比下，同步帶傳動具有較緊湊的結構。

3. Synchronized belt transmission ratio is large, and the transmission ratio of compact synchronous belt transmission can generally reach l0 or so, and in the case of large transmission ratio, its structure is more compact than that of triangular belt transmission. Because synchronous belt drive is meshing transmission, its pulley diameter is much smaller than that of triangular belt pulley relying on friction to transmit power. In addition, because synchronous belt does not need large tension force, the standard of pulley shaft and bearing can be reduced. Therefore, compared with the triangular belt drive, the synchronous belt drive has a more compact structure under the same transmission ratio.

4．同步帶維護保養(yǎng)便利，作業(yè)費用低 因為同步帶中承載繩選用伸長率很小的玻璃纖維、鋼絲等資料制成，故在作業(yè)過程中帶伸長很小，不需要像三角帶、鏈傳動等需常常調(diào)整張緊 力。此外，同步帶在作業(yè)中也不需要任何光滑，所以維護保養(yǎng)很便利，作業(yè)費用比三角帶、鏈、齒輪要低得多。 5．同步帶惡劣環(huán)境條件下仍能正常作業(yè) 盡管同步帶傳動與其它傳動比較有以上優(yōu)點，但它對安裝時的中心距要求等方面極其嚴厲，一起制作工藝雜亂、制作本錢高。

4. The synchronous belt is easy to maintain and has low operating cost. Because the load-carrying rope in the synchronous belt is made of glass fibre and steel wire with very small elongation, the belt elongation is very small in the operation process. It does not need to adjust the tension force frequently, such as triangular belt and chain drive. In addition, the synchronous belt does not need any smoothness in operation, so maintenance is very convenient, the operating cost is much lower than that of triangular belt, chain and gear. 5. Synchronized belt can still work normally under harsh environment. Although synchronous belt drive has the above advantages compared with other drives, it has very strict requirements on the center distance when it is installed, and the manufacturing process is messy and the manufacturing cost is high.
