Abstract
In order to optimize a nut and a method for the production of a nut, comprising a nut body which is provided or can be provided with an internal thread and has a polygonal section with a polygonal outer contour which has, on the one hand, edge areas and, on the other hand, key faces which are located between the edge areas and extend in key face planes extending in a manner conforming to standards, in such a manner that it has mechanical properties which are as ideal as possible with as low a weight as possible, it is suggested that the nut body have a plurality of recesses which extend into the nut body in the direction of the bore proceeding from the respective key face planes.
Claims12
Nut, comprising a nut body, said nut body having a polygonal section with a polygonal outer contour, the polygonal outer contour having edge areas and key faces located between the edge areas, the key faces extending in key face planes in a manner conforming to standards, the key face planes defining the polygonal outer contour, wherein the nut body defines internal threads of constant diameter surrounding a bore therethrough, the internal threads of constant diameter extending an entire length of the bore, the bore having a substantially cylindrical cross section;
- and wherein the nut body has a plurality of recesses extending into the nut body in a direction toward the bore proceeding from the respective key face planes to a thread-bearing casing;
- wherein the nut body has a first end face designed as a pressure side with a pressure surface and a second end face facing away from the pressure side;
- wherein the recess extends as far as a pressure flange provided on the pressure side, the pressure flange extending radially beyond the polygonal outer contour;
- the pressure surface being an axially outermost entirely planar surface, the axially outermost entirely planar surface extending radially from the bore to a radially outermost periphery of the pressure flange and
- wherein the thread-bearing casing has an increasing radial minimum thickness with increasing extension from the second end face towards the pressure side.
Nut, comprising a nut body, said nut body having a polygonal section with a polygonal outer contour, the polygonal outer contour having edge areas and key faces located between the edge areas, the key faces extending in key face planes in a manner conforming to standards, the key face planes defining the polygonal contour, wherein the nut body defines internal threads of constant diameter surrounding a bore therethrough, the internal threads of constant diameter extending an entire length of the bore and wherein the nut body has a plurality of recesses extending into the nut body in a direction toward the bore proceeding from the respective key face planes to a thread-bearing casing;
- wherein the recess extends in a first direction from the respective key face plane as far as a thread-bearing casing surrounding the internal thread in a stabilizing manner and extends in a second direction as far as a pressure flange provided on the pressure side, the pressure flange extending radially beyond the polygonal outer contour;
- wherein the nut body has a first end face designed as a pressure side with a pressure surface and a second end face facing away from the pressure side, the pressure surface being an axially outermost entirely planar surface, the axially outermost entirely planar surface extending radially from the bore to a radially outermost periphery of the pressure flange;
- and
- wherein the thread-bearing casing has an increasing radial minimum thickness with increasing extension from the second end face towards the pressure side.
