Blade wheel for hydrodynamic machine, particularly for retarder or coupling

摘要

The contour of one of each blade has a front edge, which faces the other blade wheel (3), and a convex edge. Between two adjacent blades, at least one distance holder is provided. The distance holder is at least fixed to one of two adjacent blades. The distance holder may also be of one-piece construction with one of two adjacent blades. The distance holder is formed by an arm, which is integral with the blade, and is bent at an angle in relation to the blade. The distance holder extends along the wall of the basic body. The arms form the fluid-conveying inner surface of the basic body. The blades are joined to one another by a collar, which locates on their front edges or penetrates them.
