    Introduction of common types of DC geared motor folding

    1) The main feature of the worm gear reducer is that it has a reverse self-locking function and can have a large reduction ratio. The input shaft and the output shaft are not on the same axis and are not on the same plane. But generally the volume is large, the transmission efficiency is not high, and the accuracy is not high.

    2) The harmonic transmission of the harmonic reduction motor uses the controllable elastic deformation of the flexible element to transfer motion and power. The volume is small and the accuracy is high, but the disadvantages are the limited life of the flexible wheel, the impact resistance, the rigidity and the metal parts Comparatively poor. The input speed cannot be too high.

    3) Planetary geared motors have the advantages of compact structure, small backlash, high accuracy, long service life, and large rated output torque. But the price is slightly more expensive.

    Geared motors are generally used for low-speed high-torque transmission equipment. Electric motors, internal combustion engines, or other high-speed running power are driven by gears with fewer teeth on the input shaft of the geared motor to the gears on the output shaft. The reduction motor will also have several pairs of gears with the same principle to achieve the ideal reduction effect. The ratio of the number of teeth of the large and small gears is the transmission ratio.
