摘要:
An impeller assembly and method of providing a plurality of radially-aligned aerodynamic channels including a rim plate defining a plurality of blades and the backplate defining a blade interlock structure for aligning and coupling the plates together. The rim plate defines a plurality of fluid-engaging blades with the aerodynamic channels being defined between adjacent pairs of the blades. The interlock structure includes a plurality of tine-shaped interlocks extending from the backplate. Each blade of the impeller may engage the interlock structure in a saddle manner. The backplate is defined by areas of reduced thickness allowing outer portions of the backplate to flex (rotate) toward further contact with the rim plate. The impeller assembly is provided with a plurality of aerodynamic channels defined by complex curved surfaces of the back plate and the rim plate to improve efficiency.
摘要(中):
提供多个径向对准的空气动力学通道的叶轮组件和方法,所述多个径向对准的空气动力学通道包括限定多个叶片的边缘板,并且所述背板限定叶片互锁结构,用于将所述板对齐和联接在一起。 边缘板限定多个流体接合叶片,其中空气动力学通道限定在相邻的叶片对之间。 互锁结构包括从背板延伸的多个尖齿形互锁。 叶轮的每个叶片可以以鞍形方式接合互锁结构。 背板由厚度减小的区域限定,允许背板的外部弯曲(旋转)以进一步接触边缘板。 叶轮组件设有多个由背板和边缘板的复杂弯曲表面限定的空气动力学通道,以提高效率。 p>
