同步带传动的有哪些优点和缺点?

1.同步带作业时无滑动,有准确的传动比 同步带传动是一种啮合传动,尽管同步带是弹性体,但因为其间承受负载的承载绳具 有在拉力作用下不伸长的特性,故能坚持带节距不变,使带与轮齿槽能正确啮合,完成无滑差的同步传动,取得准确的传动比。
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.同步带传动功率高,节能作用好 因为同步带作无滑动的同步传动,故有较高的传动功率,一般可达0.98。它与三角带传动比较,有明显的节能作用。
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.同步带传动比规模大,结构紧凑 同步带传动的传动比一般可到达l0左右,并且在大传动比情况下,其结构比三角带传动紧凑。因为同步带传动是啮合传动,其带轮直径比依托摩 擦力来传递动力的三角带带轮要小得多,此外因为同步带不需要大的张紧力,使带轮轴和轴承的标准都可减小。所以与三角带传动比较,在相同的传 动比下,同步带传动具有较紧凑的结构。
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.同步带维护保养便利,作业费用低 因为同步带中承载绳选用伸长率很小的玻璃纤维、钢丝等资料制成,故在作业过程中带伸长很小,不需要像三角带、链传动等需常常调整张紧 力。此外,同步带在作业中也不需要任何光滑,所以维护保养很便利,作业费用比三角带、链、齿轮要低得多。 5.同步带恶劣环境条件下仍能正常作业 尽管同步带传动与其它传动比较有以上优点,但它对安装时的中心距要求等方面极其严厉,一起制作工艺杂乱、制作本钱高。
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.
