摘要
研究的链轮内为渐开线小模数齿轮,外为变位齿轮,齿短而尖,内外齿同心度要求高,原切屑加工生产效率低且同心度不易保证。通过分析、研究,采用体积成形工艺技术将内外齿一次精密成形,并且一次可以成形多件链轮。设计、制做的成形模具结构简单、新颖,使用方便,寿命高。
In the project, inside form of the chain wheel is intenal gear and itts outside form is external gear. Internal gear is a small model involute gear, external gear is a modified gear with short and peaked tooth. The demand of coaxiality for intenal and extenal gear is high. The technology of solid forming of the chain wheel is introduced. A set of high accuracy die with simple novel structure and long service life is designed and manufactured. The internal and external gear tooth is formed at one time. In the same time, the multi part is formed. The solid forming technology is profitable reference for producting the same type of the chain wheel.
