| 摘 要： | 针对线切割加工的特点,讨论了微小齿轮的设计和主要参数的确定,舍弃了普通齿轮设计方法中对参数的一些限制条件,使微小齿轮的设计更加灵活.基于齿轮啮合理论,研究了渐开线微小齿轮轮廓的生成算法.分析了齿轮啮合中的齿廓干涉现象,设计了齿轮啮合过程仿真算法.基于ACIS几何平台,开发了面向线切割的微小齿轮设计和啮合仿真软件,实现了微小齿轮的造型,并可进行啮合过程仿真和干涉检验.最后通过一对微小齿轮的设计制造实验,验证了该方法的可行性.

| Abstract: | For the design of gears manufactured with wire electrical discharge machining (WEDM) technology,determination of the primary gear parameters is discussed considering the characteristics of the machining method.Some constraint conditions on gear parameters are abnegated,which makes micro gear design more flexible.Based on gear mesh theory,the algorithm of generating gear tooth profiles is studied,which includes involute and non-involute curve segments.The phenomena of tooth profile interferences during gear mesh are analyzed, and a gear mesh simulation algorithm is designed.Based on ACIS,the WEDM oriented software for the design and mesh simulation of micro gears is developed,by which the modeling,mesh simulation and interference check can be implemented.An experiment is carried out to design and manufacture a pair of micro involute gears,and the proposed method is proved feasible. |
