The polyoxymethylene is selected as the production data of the plastic micro planetary gear reducer, the correction formula is used to calculate the strength of the high-speed sun gear in the plastic micro planetary gear reducer, and the Ansys software is used to analyze the gears of the plastic micro planetary gear reducer. The analysis of mechanical properties and the acceptable operating conditions and service life of the plastic micro planetary gear reducer planned by the research will provide the corresponding theoretical basis for the future application of the plastic micro planetary gear reducer.
Regarding the fixed internal gear and output internal gear in the micro planetary gear reducer, the injection molding mold was planned and manufactured. The method of inserting and joining is selected for mold cavity planning. In order to make the plastic micro planetary gear reducer have satisfactory strength, the thickness of the plastic gear is greater than 1mm, so the cavity insert of the injection molding mold is not processed by photolithography technology, but the wire cutting method in electrical discharge machining is used.
Use Moldflow software to imitate the micro-injection molding process of the internal gear in the plastic micro-planetary gear reducer, in order to guess the defects that may occur in the micro-injection molding process, analyze its occurrence conditions and composition mechanism, and find out what affects the quality of the product The key factors and their effects are linked.
