Embodiment Construction

[0113] In order to make the technical problems, technical solutions and advantages to be solved by the present invention clearer, the following will describe in detail with reference to the drawings and specific embodiments.

[0114] Using solidworks for parametric modeling of gears has the following meanings:

[0115] (1) There is an equation-driven curve function in the advanced version of Solidworks. Developers only need to input the involute equation of the gear into the corresponding dialog box to draw the corresponding involute, and can improve Accuracy of involute gears;

[0116] (2) If you want to draw different gear profiles, you only need to modify the parameters of the equation in the dialog box, and Solidworks can draw the gears that meet the requirements, which is convenient and quick, and saves time;

[0117] (3) It brings great convenience to gears in terms of mechanical design, manufacturing and CAE.

[0118] The present invention provides a three-dimensional...

Abstract

The invention provides a three-dimensional automatic design method of a gear, which comprises the following steps of: (1) firstly formulating several sets of feasible gear drawing schemes according torequirements, then selecting a set of optimal scheme, and manually drawing a three-dimensional model of the gear in solidworks according to the optimal scheme; (2) expressing the three-dimensional modeling process of the gear in the step (1) by using a code, and performing compilation operation on the code in a VS to form a solidworks plug-in; (3) opening Solidworks, inserting the Solidworks intoa plug-in made in the VS, inputting corresponding design data, and automatically finishing three-dimensional modeling of the gear by the Solidworks; and (4) manufacturing a gear entity in a 3D printing mode. The system and the method are based on an SOLIDWORKS development platform. The gear parameterization entity model design process is conducted, a gear parameterization design system is developed by applying a toolkit of the gear parameterization entity model design process, corresponding involute gears can be obtained by modifying gear parameters through a created dialog box, therefore, design requirements are met, finally entities are manufactured through the 3D technology, and design of the gears is completed.

Description

technical field [0001] The technical field of mechanical design of the present invention specifically relates to a three-dimensional automatic design method for gears. Background technique [0002] Gears are used in many machines, and the frequency of use is very high. For these frequently used workpieces, if they have to design and calculate from scratch every time, the designer has to spend a lot of time on a lot of repetitive work. The quantity is large and meaningless, thus lacking time and energy to do some innovative work, resulting in high failure rate of product quality, long development time, weak market competitiveness and other shortcomings, so secondary development came into being. There are many types of gears, and the drawing methods of different types of gears are different. The design process of conventional gears is cumbersome, the workload is heavy and the design results are not reliable. [0003] The reducer is a transmission device widely used in various...
