液力变矩器叶片制作方法研究

PRODUCTION OF MOLDS FOR HYDRAULIC TORQUE CONVERTER BLADES

本文首先介绍了制作液力变矩器叶片模型的传统方法。接着 ,提出了利用液力变矩器工作轮模具进行叶片铸造的新方法 ,用该法制造的叶片具有良好的贴合性。最后 ,介绍了用计算机建立叶片三维实体模型 ,并采用数控机床直接进行加工的方法。文中较为详尽地阐述了这些方法 ,并通过对比得出各种方法的利弊。

Traditional ways of making molds for hydraulic torque converter blades were first introduced in brief. Improvements on traditional ways through CAD/CAM technology were discussed. A new way was then brought forward making use of the work wheel in the torque converter's mould. The method in producing blade molds by NC machine tools gets the program from virtual modeling in computer directly. These methods were described in more detail, and the merits and defects of each method were given by comparison.
