Abstract

A method for producing a camshaft module and a camshaft module are provided. The camshaft module includes a camshaft and a bearing frame having bearing devices with cut-outs. The camshaft includes a shaft and cams having cut-outs. The shaft has at least two different outside diameters. At least some of the cams and/or some of the bearing devices have cut-outs of differing diameters. The bearing frame is supported during shaft insertion to be movable along a movement axis during production of the camshaft module and to be substantially rigid along an insertion direction of the shaft. The shaft is inserted into the bearing frame in the insertion direction in such a way that interference fit is obtained in each case at least between the shaft and at least some of the cams. A predefined target distance between two elements such as a gear located outside of the bearing frame and a cam or bearing device located inside of the bearing frame adjacent to the element outside of the bearing frame may be obtained by partially inserting the shaft, determining a distance between the two elements, and applying an insertion force to the shaft based on the determined distance to advance the shaft to…
