摘要:
In order to make easy to change the size of a cam device in the course of press mold design, there is provided a cam device (1) including: a cam holder (2); a cam slider (3); and a cam driver (4), wherein the cam devices (1) are grouped depending on the basis of width dimensions in combination of hardness of a sliding contact surface (2a) of the cam holder and a sliding contact surface (3a) on the cam slider (3) end, and hardness of a cam surface (4a) of the cam driver (4) and a cam surface (3b) of the cam slider (3), and the design structures of the respective groups are determined in such a manner that the maximum process ability in a certain group among the groups is larger than the minimum process ability of an adjacent group having a larger width dimension, and smaller than the maximum process ability in an adjacent group having a smaller width dimension.

The abrasion loss between the cam holder sliding contact surface (2a) and the cam slider contact surface (3a) is slected to be greater than the abrasion loss between the cam driver cam surface (4a) and the cam slider cam surface (3b). The design structures of the respective groups are determined in such a manner that the maximum process ability in a certain group among the groups is larger than the minimum process ability of an adjacent group having a larger width dimension, and smaller than the maximum process ability in an adjacent group having a smaller width dimension.

Die Erfindung betrifft eine Nockenwelle (1) mit einem Nockenwellenrohr (7) und zumindest einem darauf thermisch gefügten Funktionsbauteil (2), insbesondere einem Nocken (3). Erfindungswesentlich ist dabei, dass eine Durchgangsöffnung (4) des Funktionsbauteils (2) und/oder eine Außenkontur (5) des Nockenwellenrohrs (7) bzw. einer darauf angeordneten Hülse (6) im Bereich der Fügestelle derart geformt sind, dass eine asymmetrische Verformung des Nockenwellenrohrs (7) nach dem thermischen Fügen des Funktionsbauteils (2) auf dem Nockenwellenrohr (7) zumindest minimiert ist.
摘要:
The invention relates to a camshaft, especially for motor vehicle engines, comprising a first shaft and a second shaft forming a hollow outer shaft (1) and an inner shaft (2) arranged coaxially in the outer shaft (1) and mounted in such a way that it can rotate in relation to the outer shaft (1). Said camshaft also comprises first cams (3a) arranged on the outer shaft (1) in a rotationally fixed manner, and second cams (3b) that are arranged on the outer shaft (1) and fixed to the inner shaft (2). According to the invention, the first shaft and the second shaft are supported against each other in the axial direction (x) by means of a formfitting shape (5), the first shaft, seen in the axial direction (x), comprising a first contact surface (6a) on one side of the formfitting shape (5) and a second contact surface (6b) on the other side of the formfitting shape (5), for supporting the second shaft in a rotationally movable manner by means of the formfitting shape (5).
