薄板叠层法制造罗茨鼓风机叶轮

采用薄板叠层法制造叶轮是一个全新的理念和方法。考察叶轮体的结构可以知道：叶轮体与轴线垂直的各个截面都是相同的，按这一个截面，进行精冲，然后将它们叠加组装，即可得到罗茨风机叶轮。

The Fabrication of Roots Blower Impeller by Thin Plate Laminated Method

The thin plate laminated method is applied to fabricate impeller, which is a new idea and method. We can know that impeller body with the vertical axis is the same in all cross-sections through observing the structure of impeller body. The fine blanking is carried on every section, and then laminated and assembled them. Thus the roots blower impeller is obtained.
