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.

The thread generating tool for producing a thread in a workpiece has the following features: a) the tool is rotatable about a tool axis (A), b) the tool has a number n1 of groove generating regions for generating in each case one groove in the workpiece and a number m1 of thread generating regions for generating the thread in the workpiece, c) each of the m thread generating regions is arranged behind one of the n groove generating regions as viewed in an axial projection parallel to the tool axis (A), and has a smaller extent than said groove generating region as viewed in cross section in the axial projection.

The disclosure relates to a threaded nut of a ball screw, the threaded nut having an inner sleeve made of sheet metal and an outer sleeve made of sheet metal, which are nested axially in one another to form a nut sleeve. The nut sleeve is provided with a thread, which is formed helically about a longitudinal axis of the threaded nut and which forms, on the inner circumference of the nut sleeve, a ball groove wound helically about the longitudinal axis of the threaded nut and, and on the outer circumference of the nut sleeve, a helically wound outer ridge.

A thread forming apparatus includes an outer ring having a plurality of projections disposed around an inner periphery thereof, the outer ring being structured to remain stationary, an inner ring including a plurality of recesses disposed around an outer periphery thereof, the inner ring being structured to be moved radially toward a sidewall of a can body positioned between the outer ring and the inner ring and rotated against the sidewall and the projections. The rotation against the can sidewall and the projections causes can material to flow into the recesses and form a plurality of threads around the inner circumference of the can body. An actuator is coupled to the outer ring and the inner ring and structured to hold the outer ring stationary and the inner ring radially and rotate the inner ring against the sidewall.

A thread forming apparatus includes a punch assembly having a punch cam and a punch. The punch includes a body having a first end engaged with the punch cam and a second end having a projection moved radially in response to engagement with the punch cam. The apparatus further includes a die assembly adjacent the punch assembly and defining a clearance therebetween to receive a portion of a sidewall of a can body. The die assembly includes a die cam and a die including a top portion having a die recess and a bottom portion engaged with the die cam, the die being moved radially in response to engagement with the die cam. The projection is structured to deform the portion of the sidewall of the can body into the die recess in a manner which forms the thread.
