Abstract  Sprocket is one of the key parts in the transmission part of the scraper conveyor, and its design quality has a direct impact on the transmission performance, production efficiency and working life of the scraper conveyor. Because of the complex processing of the sprocket, the theoretical design of the sprocket plays a decisive role in its actual processing. Therefore, it is very important to study the parametric design of the sprocket. The third party library of WebGL (Three.js) and JavaScript were adopted to develop the parametric design in browser. Taking the common seven tooth sprocket with the size of 14 mm×50 mm as an example, in the design of the chain nest, the sprocket was modeled by SolidWorks and the chain nest structure was analyzed in detail. A new design method of chain nest was summed up. Under the Three.js, the JavaScript parameter control function was compiled, and the parametric design of sprocket was carried out according to the sprocket design standard. And using the Web front-end development, in the LAN (local area network) environment, the Web sprocket database was set up by HTML, CSS and JavaScript language, which was convenient for the user to select and download for production and processing. Through the 3D printing technology, the sprocket wheel was printed and compared with the sprocket used in actual production, and the results showed that there was no significant difference between the model and the actual sprocket, which verified the feasibility and accuracy of the parametric design for sprocket. The results provide a reference for parametric design of other more complex components.

基于WebGL的刮板输送机链轮参数化设计方法

链轮是刮板输送机传动部分的关键件零部件之一,其设计质量直接影响着刮板输送机的传动性能、生产效率和使用寿命。由于链轮加工工艺复杂,链轮的理论设计对实际加工起着决定性作用,因此进行链轮的参数化设计研究极其重要。链轮的参数化设计是采用WebGL(Web graphics library,网页图形库)第三方库(Three.js)以及JavaScript在浏览器中进行。以常见的规格为14 mm×50 mm的七齿链轮为例,在链窝设计中,采用SolidWorks对链轮建模且详细分析链窝结构,总结出一种全新的链窝设计方法。在Three.js中通过编写JavaScript参数控制函数,按照链轮设计标准,对链轮进行参数化设计。并应用Web前端开发,在局域网环境下,通过HTML、CSS、JavaScript语言建立网页链轮数据库,方便用户选型、下载以进行生产加工。通过3D打印技术打印所建链轮并与工厂实际生产加工的链轮进行对比分析,结果表明所建链轮模型与实际生产加工链轮没有明显差异,证明了链轮参数化设计方法的可行性和准确性。研究结果为其他更复杂零部件的参数化设计提供了参考。
