Abstract

A spring washer comprises an upper and a lower operative face and tooth-like projections on those faces. The projections may extend at an angle to the respective radius of the washer, such as extending helically. A method of making the spring washer comprises rolling or drawing a circular cross-section wire of spring steel, bronze or stainless steel into a wire of trapezoidal cross-section, forming the narrow face (1) into a concave, or a peaked shape, rolling or stamping the non-parallel faces (2) with projections, and finally bending the wire into a ring shape, with the concave, or peaked face innermost to form a ring-shaped spring washer. During bending the work is supported on the narrow concave or peaked face, avoiding deformation of the ridged operative faces.
