液力变矩器叶栅绘形的计算机辅助设计方法

摘要

介绍了一种液力变矩器工作轮中扭曲叶片绘形的计算机辅助设计方法。.由水力设计得到优化后的叶栅参数——工作轮平均流线上进出口处液流角度参数.将这些液流角换算成叶片进出口的叶片角，并将叶片与内外环的交线以坐标形式表示出来，为工厂提供制造工作轮的技术文件.提出了叶片角如何确定及根据保角变换原理拟合叶片骨线的方法来确定叶片与前后盖板坐标值.计算机进行上述工作最终为工厂制造工作轮提供了快捷而又精确的工作轮制造方法.%Presents the CAD curved blades for hydrodynamic torque converter from the flow angles of the center line at the inlet and outlet of the blade by converting the flow angles into the angles of blade and generating the coordinates of the blade wheel, which results in accurate technical documents with blade angles and curve fitting center line of blade profile, and provides a quick and accurate method for calculation of the work wheels.
