The invention relates to a toothed wheel (1) having a sequence of X teeth (4), wherein each Nth tooth (4) at least partially has a smaller tooth rigidity compared to the remaining X-N teeth (4), N being a number which is selected from a range with a lower limit of 2 and an upper limit of X, in particular X/2, or wherein a number of M teeth at least partially have a smaller tooth rigidity than the remaining X-M teeth, where M is selected from a range with a lower limit of 1 and an upper limit of X-1 or an upper limit of X provided that at least individual teeth are divided or all the teeth have a different geometry, and/or wherein the tooth system (3) has a pitch in which each Nth tooth (4) stands out compared to the remaining X-N teeth (4).

The invention relates to a gear arrangement (1), comprising a main gear (2) and a gear (4) that can be rotated relative to the main gear in the circumferential direction (3), wherein the main gear (2) or the rotatable gear (4) has at least one supporting web (12) that protrudes in the axial direction (7) and the rotatable gear (4) or the main gear (2) has at least one opening (16), in which the supporting web (12) is at least partially accommodated, wherein the opening (16) has a dimension in the circumferential direction (3) that is greater than the dimension of the supporting web (12) in the same direction, and comprising at least one spring element (10), which acts in the circumferential direction (3) of the main gear (2) and which is arranged on a lateral surface (13) of the supporting web (12) or on a lateral surface (17) of the opening (16) and at least partially within the opening (16). The spring element (10) is connected to the supporting web (12) or the lateral surface (17) of the opening (16).

The invention relates to a tool for compacting the surface of a powder-metallurgically produced component (2), comprising a female die (1) and a male die (20), a clearance (5) which extends from a first female die opening (6) to a second female die opening (8) being arranged in the female die (1) and having a wall surface (10) for bearing against the component (2), and the male die (20) having a male die length (23) and a male die surface (21), wherein an inside diameter (12) of the clearance (5) in the female die (1) becomes smaller from the first female die opening (6) in the direction of the second female die opening (8) or an outside diameter (22) of the male die (20) becomes greater over the male die length (23), and wherein a compacting element (17) is arranged on the wall surface (10) of the female die (1) or on the male die surface (21). The compacting element (17) is formed with a thread-like profile.
摘要:
In einem Kraftfahrzeug sind eine Verbrennungskraftmaschine und eine elektrische Maschine über einen Riementrieb mit einer Riemenscheibe (20) und über ein Planetengetriebe miteinander gekoppelt. Die Riemenscheibe (20) ist mit einem drehbaren Element, z. B. dem Sonnenrad (16) des Planetengetriebes verbunden. Ein zweites drehbares Element, z. B. das Hohlrad (24), ist mit einer Bremsscheibe (30) verbunden, wobei Kennzeichen der Anordnung ist, dass sich die Bremsscheibe (30) radial weiter nach außen erstreckt als die Riemenscheibe (22), sodass die eigentliche Bremse (zwei Bremselemente (26) mit Sattelträger (32) und Bremsbacken (34)) außerhalb der Riemenscheibe (30) anordenbar ist. Dadurch lässt sich das Planetengetriebe mit der Riemenscheibe kompakt bauen.
