In the process of development, a new design in structure was adopted in order tn reduce the running noise of the planetary gear reducer. The innovative planetary axle radial chute structure within planetary carrier was employed to reduce the noise and vibratinn of all levels, amelinrating the noise problem. New materials were utilized fnr high-speed end planetary gear materials also. Plastic elastnmer new materials were used in high-speed end planetary gear first. Gears made of such materials have high elasticity, high toughness and strength, which can greatly reduce the running noise of high-speed end. New technology was used in manufacturing methods, such as the application of new micro injection mohting technology and the adoption of plastic parts post-processing technology, ensuring, improving the precision of gear and lowering running noise at ＇all levels. Through technological means such as new design in stnwmres, application of new materials, new techm）logy, meshing motion auxiliary transmission precision was ensured. At the same time the overall running noise of reducer could be reduced. A plastic micro three-stage planetary gear reducer with lower nnise and larger transmission ratio was eventually developed. Such technologies can guide the application of micro three-level planetary gear reducer with low noise and large transmission ratio in the fieht of tubular motor.
