聚氨酯同步带传动(见图1)、具有轻巧,不打滑、传动准确、效率高、对轴及轴承压力小,以及可以适应较小的轴间距和较大的速比等优点,在国内已得到广泛的应用。从1978年以来,我们在晶体生长设备的传动系统中,使用过八种规格的齿形带。实践证明,当模数在1.5～3时,采用展成法加工的带轮,因周节误差得到了很好的控制使传动精度较高。 Polyurethane belt drive (see Figure 1), with light, non-slip, accurate transmission, high efficiency, the shaft and bearing pressure is small, and can adapt to smaller shaft spacing and larger speed ratio advantages in China have been Wide range of applications. Since 1978, we have used eight types of toothed belts in the drive system of crystal growth equipment. Practice has proved that when the modulus in the 1.5 to 3, the use of development process of the pulley, due to the error of the week has been well controlled to drive a higher precision.
