基于SolidWorks二次开发的渐开线齿轮参数建模系统

Involute Gear Parameter Modeling System Based on Solid Works Secondary Development

渐开线齿轮是一种最常见的齿轮传动,具有其他机械传动不可代替的优点,广泛的应用于各种机械结构中。传统的渐开线齿轮设计需要工作人员进行大量的计算与查阅资料,往往需要耗费较长的时间,工作效率低也不能直接将设计结果体现在模型上,而且手工计算及其容易出错。因此本课题结合SolidWorks二次开发技术,将渐开线齿轮的参数化设计与三维建模统一起来,设计出一套参数建模系统,这样不但可以大大的减少机械工程师在齿轮设计过程中的工作量,也能极大的提高机械产品的生产效率。程序设计的主要思路是,首先使用MATLAB拟合齿轮参数设计中的图表,然后编写强度校核程序界面与后台算法,最后要链接到SolidWorks使能够根据参数设计结果自动进行三维模型的绘制。以实际工况条件为例,使用程序进行了渐开线齿轮设计,从而证明程序方法的实用性和可行性。

Involute gear is one of the most common gear drives,which has the irreplaceable advantages of other mechanical transmission,and is widely used in various mechanical structures.The traditional involute gear design needs a lot of calculation and reference,which often takes a long time,and the low efficiency can not directly reflect the design results on the model,and manual calculation and error prone.Therefore,adopting the technology of SolidWorks secondary development,this paper unifies the parametric design and 3D modeling of involute gear,and designs a set of parameter modeling system.This can not only greatly reduce the workload of mechanical engineers in the process of gear design,but also greatly improve the production efficiency of mechanical products.The main idea of the program design is to first use MATLAB to fit the graph of gear parameter design,then write the strength check program interface and background algorithm,and finally link to SolidWorks to make 3D model drawing automatically according to the parameter design results.With the actual working condition as an example,the involute gear is designed with the program,which proves the practicability and feasibility of the program method.
