| 86 | ARMATURE FOR A SELECTIVELY ENGAGEABLE AND DISENGAGEABLE COUPLING | EP01909241.0 | 2001-02-14 | EP1171721B1 | 2006-05-03 | BOYER, Charles, A.; STEINER, Jeffrey, C. |
| An armature for a selectively engageable and disengageable coupling and a method of making the armature are provided. The armature includes a substantially annular body that is disposed about a first axis. The body may be formed by stamping or fine-blanking. One side of the body is hardened through a nitriding process. A grinding wheel is then applied at an angle to the same side of the body along a diametrical line of the body extending perpendicular to the first axis. As a result, the body is configured so that the thickness of the body increases as the distance from the diametrical line increases. In particular, the thickness of the body varies along each cross-section taken along the line from a minimum thickness at the innermost portion of the cross-section to a maximum thickness at the outermost portion of the cross-section. The inventive armature reduces galling, and the resulting noise, that occur during burnishing of couplings incorporating the armature. | ||||||
