Abstract
A torque converter impeller or turbine is provided. The torque converter impeller or turbine includes a plurality of blades and a shell including a rounded portion defining an annular bowl for receiving the blades on an interior surface of the shell. The interior surface of the shell is provided with at least one shell protrusion for each of the blades protruding away from the rounded portion. Each of the at least one shell protrusion contacts a radially extending circumferentially facing surface of the respective blade.
Claims20
A torque converter impeller or turbine comprising:
- a plurality of blades;
- and
- a shell including a rounded portion defining an annular bowl for receiving the blades on an interior surface of the shell, the interior surface of the shell being provided with at least one shell protrusion for each of the blades protruding away from the rounded portion, each of the at least one shell protrusions contacting a radially extending circumferentially facing surface of the respective blade, each of the at least one shell protrusions being formed from an embossed material of the shell.
A method of forming a torque converter impeller or turbine comprising:
- forming a plurality of shell protrusions on an interior surface of a shell by embossing an exterior surface of the shell, the shell including a rounded portion defining an annular bowl, the shell protrusions protruding away from the rounded portion;
- and
- inserting a plurality of blades in the rounded portion, each of the blades being aligned on the shell by at least one of the protrusions, each shell protrusion contacting a radially extending circumferentially facing surface of the respective blade.
A torque converter impeller or turbine comprising:
- a plurality of blades;
- and
- a shell including a rounded portion defining an annular bowl for receiving the blades on an interior surface of the shell, the interior surface of the shell being provided with at least one shell protrusion for each of the blades protruding away from the rounded portion, each of the at least one shell protrusions contacting a radially extending circumferentially facing surface of the respective blade,
- the at least one shell protrusion including a first shell protrusion and a second shell protrusion for each blade, the first and second shell protrusions contacting opposite radially extending circumferentially facing surfaces of the respective blade,
- a convex curved edge of each of the blades being received between the first shell protrusion and the second shell protrusion contacting the respective blade,
- the blade including at least one blade protrusion extending from the convex curved edge.
