Abstract
A method of manufacturing an impeller and turbine assembly of a transmission includes providing an impeller housing and a turbine housing. An impeller blade defining an impeller receptor and a turbine blade defining a turbine receptor are provided. The impeller blade is mated to the impeller housing by deforming a portion of said impeller housing into the impeller receptor. The turbine blade is mated to the turbine housing by deforming a portion of the turbine housing into the turbine receptor. In this manner, the impeller blade is secured to the impeller housing and the turbine blade is secured to the turbine housing.
Claims23
A method of manufacturing an impeller and turbine assembly of a transmission, comprising the steps of:
- providing an impeller housing and a turbine housing;
- providing an impeller blade defining an impeller receptor and a turbine blade defining a turbine receptor;
- and
- mating said impeller blade to impeller housing by deforming a portion of said impeller housing into said impeller receptor and mating said turbine blade to said turbine housing by deforming a portion of said turbine housing into said turbine receptor;
- thereby securing said impeller blade to said impeller housing and said turbine blade to said turbine housing.
A method of manufacturing an impeller assembly, comprising the steps of:
- providing an impeller housing defining an arcuate wall encircling a central housing opening, with said arcuate wall having a concave side and a convex side;
- forming a plurality of circumferentially spaced, elongated grooves into said convex side of said impeller housing, with said grooves stretching radially outwardly along said arcuate wall from said central housing opening;
- providing a plurality of impeller blades, each defining a housing tab having a receptor;
- inserting said housing tab defined by each impeller blade into said groove formed into said impeller housing;
- and
- deforming a portion of said impeller housing adjacent said groove into said receptor defined by said impeller blade thereby securing said impeller blade to said impeller housing.
A method of manufacturing a turbine assembly, comprising the steps of:
- providing an turbine housing defining an arcuate wall encircling a central housing opening, with said arcuate wall having a concave side and a convex side;
- piercing a slot into said arcuate wall with said slots extending radially outwardly along said arcuate wall from said central housing opening and having an edge offset from said wall;
- providing a turbine blade having a tab defining a receptor;
- inserting said tab of said turbine blade into said slot and deforming said edge into said receptor thereby securing said turbine blade to said turbine housing.
