谐波齿轮传动是机械啮合传动的一种变型。这种传动必需有一个柔性薄壁齿轮。由于塑科具有较高的柔性,因此,用塑料来制造谐波传动齿轮是很有前途的。图1和图2所示为双波塑料谐波齿轮传动。在实际应用中谐波齿轮传动有单波、双波、三波和四波。从柔性齿轮的工作条件来看,其直径大些、波数少些为佳。通常塑料谐波齿轮传动柔性齿 Harmonic gear drive is a mechanical meshing transmission variant. This drive must have a flexible thin-walled gear. Due to the high flexibility of Plastic Branch, it is very promising to make harmonic drive gear with plastic. Figure 1 and Figure 2 shows the double-wave plastic harmonic gear drive. In practice, harmonic gear drive with a single wave, two waves, three waves and four waves. From the working conditions of the flexible gear point of view, its larger diameter, wave number less better. Plastic harmonic gears are usually driven by flexible teeth
