Embodiment Construction

[0020] according to figure 1 , in accordance with the invention for the manufacture of a bearing assembly 1 with which, for example, a control shaft / camshaft 2 is subsequently mounted in a cylinder head 3 or a cylinder head cover 4 (cf. Figure 4 ))), the bearing 5 is first prepared or manufactured by installing or arranging the roller body 6 in the bearing ring 7. The term "control shaft" is frequently synonymous with the term "camshaft" below. The roller bodies 6 can in this case be configured as rollers or needle rollers as well as balls. The bearing 5 with two rings 8 arranged on its front side, in particular with plastic or metal rings, is then pushed onto the assembly mandrel 9 (see figure 1 ), where the two rings 9 are pretensioned towards the front side of the bearing 5 by the corresponding sleeve 10 . This is brought about by the sleeve 10 being pressed onto the upper ring 8 and the lower ring 8 resting on the support or stop 11 of the component mandrel 9 . The te...

Abstract

The invention relates to a method for producing a control shaft (2), in particular a camshaft, wherein a bearing (5) is provided, which is connected with two rings (8) arranged on its front side Push together onto the assembly mandrel (9), pre-tension the two rings (8) to the front side of the bearing (5), push the telescoping hose (12) to the bearing (5) and The prefabricated bearing assembly (1) is assembled on the two rings (8) and shrinked by heating, or by wrapping a film tape (12') on the bearing (5) and the two rings (8) Withdraw from the assembly mandrel (9). In this way in particular the production of the control shaft ( 2 ) can be considerably simplified and cheaper.

Description

technical field [0001] The invention relates to a method of manufacturing a bearing assembly for mounting a control shaft. The invention further relates to a bearing assembly manufactured by this method and a method of manufacturing a control shaft using such a bearing assembly. Background technique [0002] The manufacture of camshafts or control shafts generally takes place mainly by combining individual components, such as bearings and cams, on the camshaft, whereupon the camshaft is ground, especially in the region of the cams, and thus polished. In particular, during this polishing process by grinding, grinding dust is generated which can penetrate into the bearing, in particular into the bearing surface, and stay there, and during the subsequent operation of the internal combustion engine equipped with the camshaft This can lead to increased wear and, in the worst case, even damage to the bearing. For this reason, it is known to protect bearings, such as roller beari...
