The invention relates to a stamped centering plate (10) for a torque converter with a first annular surface (12) having at least one arcuate slot (16), a second annular surface (14) opposite the first annular surface, and at least one arcuate segment (20) axially protruding downward from the second
The invention relates to a stamped centering plate (10) for a torque converter with a first annular surface (12) having at least one arcuate slot (16), a second annular surface (14) opposite the first annular surface, and at least one arcuate segment (20) axially protruding downward from the second annular surface. The slot has an inner radius and an outer radius, the segment has an inner radius and an outer radius, and at least one of the slot radii is equal to at least one of the segment radii. In an example embodiment of the invention, the segment comprises material displaced to form the slot.

1. A stamped centering plate for a torque converter comprising: a first annular surface;a second annular surface opposite the first annular surface;at least one arcuate slot passing through the plate and opening to the first and second annular surfaces; and,at least one arcuate segment protruding from the second annular surface such that the at least one segment is separated from the second annular surface in a first direction parallel to an axis for the centering plate and including first and second circumferential ends one of which is connected to the first annular surface, wherein: at least a portion of the at least one arcuate segment is aligned with the at least one arcuate slot such that a line parallel to the axis passes through the at least one segment and the at least one arcuate slot;the at least one slot has a first inner radius and a first outer radius, the first inner radius less than the first outer radius;the at least one segment has a second inner radius and a second outer radius, the second inner radius less than the second outer radius;the centering plate is a side plate for a stator of the torque converter; and the first and second inner radii are equal; or,the first and second outer radii are equal. 2. The centering plate of claim 1, wherein the segment comprises material displaced to form the slot. 3. The centering plate of claim 1, wherein the segment is formed by material displaced to form the slot. 4. The centering plate of claim 1, wherein: the at least one slot comprises at least three slots;the at least one arcuate segment comprises at least three corresponding arcuate segments; andeach of the at least three corresponding arcuate segments is aligned, in the first direction, with a respective slot from the at least three slots. 5. The centering plate of claim 1, wherein a height of the segment relative to the second annular surface is selected to ensure a bearing remains centered by the segment. 6. A method of forming a centering plate for a torque converter comprising the steps of: blanking an annular disk including first and second oppositely facing annular surfaces;displacing an arcuate segment having first and second circumferential ends, a second circumferential end, a first inner radius, and a first outer radius out of the disk such that the arcuate segment is separated from the disk in a line parallel to a axis for the centering plate, the first inner radius less than the first outer radius, and each of the first and second circumferential ends are connected to the first annular surface; and,forming a slot passing through the plate, axially aligned with the arcuate segment such that a line parallel to the axis passes through the slot and the arcuate segment, and opening to the first and second surfaces, wherein: the first and second inner radii are equal; or,the first and second outer radii are equal. 7. The centering plate of claim 1, wherein each of the first and second circumferential ends are connected to the first annular surface. 8. The method of claim 6, wherein the centering plate is a side plate for a stator of the torque converter. 9. The method of claim 6 further comprising selecting a height of the segment relative to the second annular surface to ensure a bearing remains centered by the segment. 10. A stamped centering plate for a torque converter comprising: a first annular surface;a second annular surface opposite the first annular surface;at least one arcuate slot passing through the plate and opening to the first and second annular surfaces; and,at least one arcuate segment protruding from the second annular surface such that the at least one segment is separated from the second annular surface in a direction parallel to an axis for the centering plate and including first and second circumferential ends one of which is connected to the first annular surface, wherein: at least a portion of the at least one arcuate segment is aligned with the at least one arcuate slot such that a line parallel to the axis passes through the at least one segment and the at least one arcuate slot;the at least one slot has a first inner radius and a first outer radius, the first inner radius less than the first outer radius;the at least one segment has a second inner radius and a second outer radius, the second inner radius less than the second outer radius;a height of the segment relative to the second annular surface is selected to ensure a bearing remains centered by the segment; and, the first and second inner radii are equal; or,the first and second outer radii are equal. 11. The centering plate of claim 10, wherein each of the first and second circumferential ends are connected to the first annular surface.
