Problems solved by technology
However, since the preparation of the teeth of the gears takes place before shrink fitting the gears to the shaft body, it is not possible to observe the narrow positional tolerances and true rotational accuracy between the teeth of the gears on the shaft body and the extruded bearing housings and other functional elements
This often results in a relatively short service life of the gears of the camshaft, or it is often not possible to simply extrude the gears onto the shaft body to manufacture the camshaft, since extrusion results in the teeth of the gears and the functional elements produced by the grinding process Excessive positional deviation between (eg bearing element and cam element)

Embodiment Construction
[0021] figure 1 An exemplary embodiment of a receiving assembly 1 is shown, which has an exemplary embodiment of a camshaft 10, and with which an exemplary embodiment of a receiving assembly 1 shown in the figure can be used for grinding according to the invention Method for machining camshaft 10.
[0022] The camshaft 10 is only partially shown and comprises a shaft body 11 in the form of a hollow shaft, on which two functional elements 12 are arranged, for example. The first functional element 12 forms a bearing element 20 for mounting the camshaft 10 in the cylinder head of the internal combustion engine, the other functional element 12 is for example in the form of a cam element 24 . The bearing element 20 is shown for example as a single annular element which is pushed onto the shaft body 11 , and the bearing element 20 may also be formed by a section of the shaft body 11 . For example, this section of the shaft body 11 and the outer peripheral surface of the bearing el...

The invention relates to an accommodating assembly (1) for accommodating a camshaft (10), to a method for grinding the camshaft (10), and to such a camshaft (10), wherein the camshaft (10) comprises a shaft body (11) having functional elements (12), which shaft body extends in an axis of rotation (13), and wherein a gear (14) is placed on the shaft body (11), wherein an accommodating body (15) is provided, by means of which the camshaft (10) can be at least partially accommodated in order to perform grinding. According to the invention, the gear (14) has an accommodating means (16), against which the accommodating body (15) can be placed and by means of which the accommodation of the camshaft (10) by the accommodating body (15) is enabled.
Description
technical field [0001] The invention relates to a receiving device for receiving a camshaft, wherein said camshaft comprises a shaft body with a functional element, said shaft body extending along an axis of rotation, and wherein a gear is mounted on said shaft body, wherein the receiving body is arranged , the camshaft can be at least partially received by the receiving body for the purpose of performing a grinding process. The invention also relates to a method for grinding a camshaft by means of a receiving assembly of said type, and also to a camshaft which can be received in a receiving assembly according to the invention. Background technique [0002] DE 10 2005 034 777 B3 describes a camshaft that can be received in a receiving assembly, so that the camshaft can be subjected to a grinding process in the receiving assembly. Here, a shaft body is proposed, on which the functional elements of the camshaft and the gear wheels are mounted, and it is pointed out that the f...
