Abstract
Methods and apparatus for manufacturing a circular laminated component are disclosed herein. In one embodiment, a method comprises stamping an inlet stock of material to form a line of arc segments, the line of arc segments having: a plurality of notches along a first edge; a first longitudinal end; and a second longitudinal end opposite the first longitudinal end; wrapping the line of arc segments to form a circular segment having the first edge along an inner-circumferential diameter of the circular segment; joining the first longitudinal end to the second longitudinal end to form a circular laminate layer; and stacking a plurality of circular laminate layers to form a laminate disc.

A method comprising:
- stamping an inlet stock of material to form a line of arc segments, the line of arc segments having:
- a plurality of notches along a first edge;
- a first longitudinal end;
- and
- a second longitudinal end opposite the first longitudinal end;
- wrapping the line of arc segments to form a circular segment having the first edge along an inner-circumferential diameter of the circular segment;
- joining the first longitudinal end to the second longitudinal end to form a circular laminate layer;
- and
- stacking a plurality of circular laminate layers to form a laminate disc.
A laminate disc comprising a plurality of stacked circular laminate layers, each layer in the plurality of stacked circular laminate layers is formed by:
- stamping an inlet stock of material to form a line of arc segments, the line of arc segments having:
- a plurality of notches along a first edge;
- a plurality of cutouts along a second edge that opposes the first edge, the plurality of cutouts located opposite of the plurality of notches;
- at least one pilot hole;
- a first longitudinal end;
- and
- a second longitudinal end opposite the first longitudinal end;
- forming the line of arc segments into a circular segment at least in part by:
- securing the line of arc segments at a pilot hole located in proximity to the first longitudinal end;
- and
- pulling the line of arc segments by the secured pilot hole around a circular tool such that the first edge forms an inner-circumferential diameter of the circular segment and the second edge forms an outer-circumferential diameter of the circular segment;
- and
- joining the first longitudinal end to the second longitudinal end to form a circular laminate layer.
A method comprising:
- stamping an inlet stock of material to form a line of arc segments, the line of arc segments having:
- a plurality of notches along a first edge;
- a plurality of cutouts along a second edge opposing the first edge, the plurality of cutouts located opposite of the plurality of notches;
- at least one pilot hole;
- at least one dimple that forms a protrusion on one side of the line of arc segments and a pocket on an opposing side of the line of arc segments;
- a first longitudinal end;
- and
- a second longitudinal end opposite the first longitudinal end and mateable with the first longitudinal end;
- securing the line of arc segments at a pilot hole located in proximity to the first longitudinal end;
- pulling the line of arc segments around a circular tool to form a circular segment, such that the first edge forms an inner-circumferential diameter of the circular segment and the second edge forms an outer-circumferential diameter of the circular segment;
- mating the first longitudinal end to the second longitudinal end to form a circular laminate layer;
- stacking a plurality of circular laminate layers by aligning a dimple protrusion on a first laminate layer with a dimple pocket of a second laminate layer;
- joining the stacked plurality of circular laminate layers to form a laminate disc;
- and
- finishing an outer diameter of the laminate disc at least in part by notching a saw-tooth pattern on the outer diameter of the laminate disc.
