STATOR HOUSING AND METHOD THEREOF

摘要

A method for fabricating a stator including positioning a cutting device, with a diameter equal to a desired pocket diameter, with respect to pockets in a side of a housing. Each pocket has an end wall with an indentation. The method axially displaces the device to remove material from side and end walls for the pockets to form desired diameters and lengths for the pockets, while leaving a portion of the respective indentation in place. The housing includes a plurality of blades. Each pocket is arranged to receive an engagement assembly for a one-way clutch. Each pocket includes a first opening facing in a second axial direction and a second opening in communication with the first opening and at least partially facing in a circumferential direction. The first side faces the second axial direction and the side walls are in communication with the first and second openings.

1. A method for forming a stator for a torque converter, comprising:
positioning, with respect to each pocket in a plurality of pockets in the first side of a housing for the stator, a cylindrically-shaped cutting device with an outer diameter equal to a desired diameter for said each pocket; rotating the cylindrically-shaped cutting device about a longitudinal axis for the cylindrically-shaped cutting device; axially displacing the rotating cylindrically-shaped cutting device in a first axial direction to contact a respective cylindrical wall for said each pocket; removing, with the cylindrically-shaped cutting device, respective material from the respective side wall; removing, with the cylindrically-shaped cutting device, respective material from a respective ring-shaped surface forming a portion of a respective end wall for said each pocket, the end wall including a respective indentation:
in contact with the respective ring-shaped surface;substantially centered with respect to the respective ring-shaped surface; and,extending further than the respective ring-shaped surface in the first axial direction; forming, with the cylindrically-shaped cutting device, a respective diameter of the respective side wall for said each pocket equal to the desired diameter; forming, with the cylindrically-shaped cutting device, a respective length, in the first axial direction, of the respective side wall for said each pocket equal to a desired length; and, leaving a portion of the respective indentation in place, wherein: the housing includes:
a radially inner circumference; and,a plurality of blades circumferentially spaced in a radially outermost portion of the housing;each pocket in the plurality of pockets:is arranged to receive a respective engagement assembly for a one-way clutch for the stator; and,is disposed in a region radially between the inner circumference and the plurality of blades;each pocket in the plurality of pockets includes:
a respective first opening facing in a second axial direction opposite the first axial direction;a respective second opening in communication with the respective first opening and at least partially facing in a circumferential direction; the first side faces in the second axial direction; and, the respective cylindrically-shaped side wall is in communication with the respective first and second openings.
