摘要
提出一种基于SolidWorks二次开发实现非圆齿扇三维参数化建模的方法。利用展成法加工原理,在SolidWorks/VBA中编写程序代码对加工刀具及齿扇毛坯进行参数化建模,根据传动比曲线模拟齿扇插齿加工过程,生成非圆齿扇三维模型。将齿扇、齿条三维模型装配,进行动态干涉检测,并使用克林根贝格齿轮检测中心进行检测对比,以验证模型的正确性。结果表明使用这种建模方法得到的非圆齿扇三维模型是可行的,极大地方便了产品设计工作。
A method based on SolidWorks secondary development is proposed to realize three-dimensional parametric modeling of non-circular gear sector.Using the processing principle of the forming method,the program code is programmed in SolidWorks/VBA to parametrically model the machining tool and the gear,and the machining process of the gear sector is simulated according to the gear ratio curve to generate a three-dimensional model for the non-circular gear sector.The threedimensional model for the gear sector and the rack is assembled and subjected to dynamic interference detection,and Klingenberg Fiber Gear Testing Center for inspection and comparison is used to verify the correctness of the model.The results show that the present three-dimensional model for non-circular gear sector is feasible,which greatly facilitates the product design requirement.
