[Abstract]:By rationally distributing the transmission ratio of three stage planetary gear at all levels and using Solid Words three-dimensional software, a miniature three stage planetary gear reducer with plastic gear as the main body is designed for the use of tubular motor. In the course of development, a new design is adopted in order to reduce the noise of the planetary gear reducer, that is, the new design is adopted. The structure of the planetary axles in the planetary frame reduces the noise and vibration at all levels and improves the noise problem. The high speed end planetary gear materials use new materials, that is, the first plastic elastomer material is used at the high speed end planet gear. The gear made with the material has high resilience, high toughness and strength. To reduce the operation noise at the high speed end, the new technology is used in the manufacturing method, that is, the new technology of micro injection molding and the use of the post processing technology of plastic parts to improve and guarantee the precision of the gear and reduce the noise at all levels. The transmission precision of the meshing motion pair is guaranteed and the overall operation noise of the reducer is reduced. A low noise and large transmission ratio plastic miniature three stage planetary gear reducer is developed. These technical means can guide the popularization and application of the low noise and large transmission ratio micro three stage planetary gear reducer in the field of tubular motor.
