摘要： A lock washer for a screw connection between a screw part and a component, having an annular washer body which is delimited by a peripheral outer rim and an inner rim, having a receiving bore, delimited by the inner rim, into which the screw part is insertable, having an upper annular surface which is provided on an upper side of the washer body and has a toothing, having a lower annular surface which is provided on a lower side of the washer body and has a toothing which extends fully on the lower annular surface, wherein the toothing on the upper annular surface extends fully circumferential in a toothed region, the width of the toothed region on the upper annular surface is smaller than the width of the washer body between the outer rim and the inner rim, and an untoothed region is formed on the upper annular surface between the toothed region and the outer rim of the washer body.

摘要： A method for producing a flat spiral spring formed as an annular disk-shaped segment, wherein a strip-shaped material is supplied in a tangential alignment to the lateral surface of the drum such that a lateral wall which determines the thickness of the strip-shaped material rests against some sections of a contact surface on the lateral surface of the drum. The contact surface of the drum has a radius which substantially corresponds to an internal radius of the strip-shaped material, and at least one deflecting device is aligned at a distance to the drum such that the strip-shaped material is guided in a forced manner between the drum and the deflecting device, and the strip-shaped material is bent so as to follow the drum by means of the deflecting device.
