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

　　1. 同步带工作时无滑动，传动比准确

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

　　同步带传动是一种啮合传动。虽然同步带是一个弹性体,轴承绳轴承负载的特点没有拉伸张力的作用下,所以带间距可以保持不变,这样可以编织皮带和齿轮槽正确,实现同步驱动没有滑动,获得准确的传动比。

　　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.

　　Advantages and disadvantages of synchronous belt drive

　　2. 同步带传动效率高，效果好

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

　　由于同步带作为无滑动同步传动，它具有较高的传动效率，一般可达0.98。与三角皮带传动相比，效果明显。

　　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.同步带传动比大，结构紧凑

　　3. Large transmission ratio and compact structure of synchronous belt

　　同步带的传动比一般可达l0左右，在传动比较大的情况下，其结构比三角皮带传动更紧凑。由于同步带传动是啮合传动，所以同步带轮的直径远小于依靠摩擦力传递动力的三角带轮。另外，由于同步带不需要很大的张力，所以可以减小带轮轴和轴承的尺寸。因此，与三角皮带传动相比，在相同传动比下，同步带传动结构相对紧凑。

　　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. 同步带维护方便，运行成本低

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

　　由于同步带中的轴承绳是由玻璃纤维、钢丝等材料制成，伸长率非常小，所以在运行过程中，带的伸长率非常小，不需要调节三角带、链传动等张力。此外，同步带在运行中也不需要任何润滑，所以维护非常方便，运行成本远低于三角带、链条、齿轮。

　　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. 同步带能在恶劣的环境条件下正常工作

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

　　虽然同步带传动与其他传动相比具有上述优点，但同步带传动在安装过程中对距的要求极为严格，同时制造工艺复杂，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.
