Design and Manufacture of Helical Planetary Gear Reducer with Small Module and Big Helical Angle

Aiming at the helical planetary gear reducer with the small module (m≤0.8mm) and big helical angle (β≥20°) applied widely, a novel method of the design and manufacture is come up. The developed reducer matched with the suitable motor not only reduces output speed and inertia of the motor, but also increases greatly stability of tooth meshing. Thus, it could reduce transmission noise and favorably increase the output torque of the motor. So it has a wide application prospect.
