Beschreibung
Zusammenfassung:	FIELD: mechanical engineering. ^ SUBSTANCE: method comprises winding working turns made of wire and one compressed bearing turn from both of the ends of the spring, cutting the ends, heat treating, quenching, measuring, and covering the spring. When winding the spring, one of the ends is provided at least with one additional compressed turn. A section of the turn is cut after quenching. The section of the additional turns which should be cut is determined from the formula alpha = (Lact - Lspec) 360° / dw, where alpha is the angle at which the section of the additional turn of the spring to be cut is located, Lact is the actual free length of the spring after quenching, and Lspec is the specified free length of the spring . ^ EFFECT: simplified manufacturing. ^ 3 dwg
