SolidWorks software is a software developed by American SolidWorks company, which integrates two-dimensional design, three-dimensional design and finite element analysis. It is a modeling software that implements digital design and has been widely used in the world. SolidWorks software has an open system. After adding various plug-ins, it can realize the three-dimensional modeling, assembly verification, motion simulation, finite element analysis, machining simulation, NC machining and the formulation of machining process of products, and ensure the consistency of data in the process of design, engineering analysis, process analysis, machining simulation and product manufacturing, So as to truly realize the digital design and manufacturing of products, and greatly improve the design efficiency and quality of products. With the help of the equation function module of Solidworks, this paper discusses the parameterized accurate modeling design of involute gear, so as to improve the efficiency of gear modeling and meet the needs of gear personalized design.
Using SolidWorks software to realize the parametric design of involute gear is the process that the designer presets the gear parameter constraints in SolidWorks software to realize the automatic design of gears according to the needs of customers and the specific problems raised in the actual design. The parametric design process of involute gear is shown in the figure. Firstly, the gear problem to be solved is analyzed in detail, and the key constraints are determined according to the actual problem, that is, the geometric parameter variables of the gear, and the unique model can be determined through the parameter variables; Secondly, with the help of the equation function module of Solidworks, the variable equation is constructed, and the corresponding variables in the equation are selected in the involute stage to complete the involute design; Finally, observe whether the drawn gear model meets the requirements. If it meets the requirements, save the output design model, otherwise return to the original design analysis and re analyze the design requirements to complete the gear model design.
