Abstract

A blade assembly for a torque converter including a shell with an inner surface and a plurality of blades attached to the shell by brazing. Each blade has a first surface for guiding a fluid in the torque converter and a second surface substantially parallel to the inner surface. The blades may include sheet steel and may be made by stamping. In an example embodiment of the invention, each blade includes at least one tab, the shell comprises a plurality of slots or indents, and the at least one tab is disposed in a respective slot or indent. The shell may be an outer shell or a core ring for a pump or turbine for the torque converter.
