A device for producing a gear green compact from a powder includes a die, an upper stamp, and a lower stamp, wherein the die has at least one helical toothing on an inner lateral surface, which helical toothing extends only over a partial area of the circumference of the inner lateral surface, and which has a first helix angle, wherein, adjoining the first helical toothing in a circumferential direction, one toothed edge surface is formed on each side, both of which have a second helix angle, wherein at least one of the second helix angles of the die is unequal to the first helix angle of the helical toothing of the die.

A torque-transmitting clutch includes a first clutch element having a first base body and a first end face, a second clutch element, and a third clutch element having a third base body. In a closed position, the first and the second clutch elements are connectable in a positive locking and/or force-fit manner for transmitting torque, and in an open position, this positive locking and/or force-fit connection is released, and wherein the first clutch element is connectable to the third clutch element in a positive locking and/or force-fit manner. The first clutch element is produced according to a powder-metallurgical or an additive method and has at least one centering projection arranged on the first end face and extending towards the third clutch element to cooperate with and/or be accommodated with a centering recess in an end face in the third clutch element in a positive locking and/or force-fit manner.

Clutch

The invention relates to a method for pressing a green compact () for producing a sintered molded part from a sintering powder, according to which the sintering powder is filled into a mold cavity () of a die (), and then the sintering powder is pressed by at least one punch, which is pushed at least partly into the mold cavity (), to form a green compact (), wherein to form an undercut in the green compact () a portion of the sintering powder is pushed by a punch out of a first plane of the die () by forming an opening () in the first plane in pressing direction into a second plane of the die () different from the first plane. The invention also relates to a device () for performing said method and a correspondingly produced sintered molded part.

Method and device for pressing a green compact

The invention relates to an assembly () at least comprising a first metal component () having a first surface region () and a second metal component () having a second surface region (), wherein the two surface regions () face each other, and the first and the second component () are connected cohesively together at least in a subregion of the two surface regions (), and wherein at least one of the two metal components () is a sintered component, wherein that surface region () of the sintered component that has the cohesive connection has a higher density than the adjoining further surface region of the sintered component.

Assembly having two components connected cohesively together

A method and a device stretches and forms a foil blank and a product is produced by this method. The foil blank is stretched in at least one direction and slides along in at least one direction during the deformation. The sliding along may be controlled, and the clamping force and the clamping speed may be regulated.

Synchronizer hub

The invention describes a device () for calibrating a sintered molded part () with an angular toothing () by means of a calibrating tool (), comprising a lower punch () for mounting the sintered molded part () with a lower punch external toothing (), a vertically movable and axially rotatably mounted upper punch () with an upper punch external toothing (), as well as an axially rotatably mounted die () with a die internal toothing (). The lower punch () is mounted to be moveable only in vertical direction.

A sintered coupling ring () is described, comprising a ring of coupling teeth () which comprise relieved flanks () extending from wedge-shaped end faces () and, on the side opposite the wedge-shaped end faces (), a stop () that protrudes radially beyond the tooth tip (). In order to provide advantageous constructional conditions it is proposed that the stops () have a greater density than the remaining tooth tip ().
