摘要
AME是一种实体造型技术。在双螺杆几何造型中引入AME,不仅可以绘制二维工程图,而且可以动态显示双螺杆的几何形状,检验两螺杆在啮合区的啮合状态会否产生“干涉”现象,这对双螺杆几何特性参数的合理选择和科学设计具有重要的指导意义。本文以紧密啮合同向平行双螺杆为实例对其啮合机理和三维实体造型原理进行了阐述。
AME is a kind of solid modeling technique. By introducing AME to bon-serew grometry modeling, we can not only get its 2D figure, but also show 3D figure dynamically. Furthermore, we can check if the two intermeshing screws could intersect, which is very important to twin-screw design. In this article, taking the close-intermeshing corotating bon-screw as an example, we analyze its intermeshing mechanisms by using AME.
