Method for assembling a built-up camshaft and hood module

摘要

The present invention relates to a method of manufacturing a built-in camshaft having a defined thrust bearing clearance within a cylinder head cover, the assembled cam shaft having at least one shaft and a thrust bearing ring. The method comprises at least the following steps: a) pre-positioning of the at least one axial bearing ring in the cylinder head cover such that the axial bearing ring contacts a stop surface of the cylinder head cover with one of its end faces, b) at least cooling the shaft or heating the cylinder head cover, in particular the axial bearing ring, c ) Arranging the shaft in the cylinder head cover such that at least a portion of the shaft extends through a through hole of the axial bearing ring, d) at least heating the shaft or cooling the cylinder head cover, in particular of the axial bearing ring, such that a press fit between the thrust bearing ring and the shaft arises and the thrust bearing ring is moved in the axial direction of extension of the shaft. Furthermore, the present invention relates to a hood module comprising at least two built in a cylinder head cover of the hood module built camshafts.
