Embodiment Construction

[0018] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples, and detailed descriptions are as follows with accompanying drawings:

[0019] See figure 1 , A parametric design modeling method of RV reducer,

[0020] It is divided into two major contents: parametric design data flow model establishment and parametric design system establishment.

[0021] The establishment of the parametric data flow model of the RV reducer is divided into four steps. First, the product structure is modularized and serialized. According to the working principle of the product, the parts are divided into three categories: first-level reduction part, second-level reduction part And the output department. On this basis, the parameters are divided into different levels according to the structural characteristics, and the characteristic dimensions are analyzed to determine the driving size and the driven size. The driving ...

Abstract

The invention provides an RV reducer parametrization design modeling method comprising a first step of establishing a parametrization data flow model and a second step of establishing a parametrization design system. The first step comprises the sub-steps of: performing module division and series division on a product structure; dividing parts into a first-stage speed reduction part, a second-stage speed reduction part and an output part according to the working principles of the product; dividing parameters into different levels according to structural characteristics, and analyzing various feature sizes to determine the drive size and the driven size, wherein the drive size is the design target size; then optimizing the design flow of the reducer and dividing the whole design flow into four stages, which are an initial parameter input stage, a product initial design stage, a product optimization design stage and a product detail design stage; finally realizing the delivery of input and output information of design feature parameters of each part through design and cooperation relationships. The parametrization design system comprises a parametrization design preprocessing module and a result postprocessing module.

Description

Technical field [0001] The invention relates to the technical field of reducers, in particular to a parametric design modeling method for RV reducers. Background technique [0002] RV reducer is widely used in robot transmission because of its small size, high efficiency, large transmission ratio and long life. From a domestic perspective, under the fierce market competition, product design technology that reduces costs and quickly responds to user needs is of great significance for improving corporate efficiency and enhancing corporate market competitiveness. However, the current mainstream design methods in the field of mechanical design are still at the stage of two-dimensional graphics digital software design represented by AutoCAD. Large workload and repetitive work will lead to long design cycles, high design costs and unintuitive design processes. , Errors in the design are not easy to find. With the development of 3D graphics technology and computer technology, the idea...
