Abstract: A method for producing a bearing assembly for mounting a control shaft, for example a camshaft, may include: providing a bearing; arranging at least two rings on respective axial front sides of the bearing; pushing the bearing together with the at least two rings onto an assembly mandrel; pre-tensioning the at least two rings against the respective axial front sides of the bearing; at least one of (i) pushing a shrink hose over the bearing and the at least two rings and heating the shrink hose, and (ii) winding a film strip over the bearing and the at least two rings; and withdrawing the assembly mandrel.

Abstract: A camshaft may include a tube-like outer shaft and an inner shaft arranged coaxially thereto and at least partially rotatable with respect to the outer shaft. The inner shaft may have an end section with a reduced external diameter. The inner shaft may be sealed with respect to the outer shaft at the end section.

Abstract: An assembled camshaft and a method for producing an assembled camshaft are disclosed. The assembled camshaft may include a camshaft main body having a longitudinal axis. The camshaft main body may include a first axial section and a second axial section disposed between the first axial section and a third axial section. The second axial section may have an outer profile including a toothing extending in an axial direction. At least one sliding cam may be arranged on the second axial section. A drive wheel may be arranged on a free end of the first axial section, and a receiving element may be arranged on at least one of the first axial section and the third axial section.

Abstract: A camshaft may include a tubular outer shaft and an inner shaft arranged coaxially thereto. The inner shaft may be rotatable at least partially with respect to the outer shaft. An annular gap may be disposed between the inner shaft and the outer shaft. The outer shaft may include at least one radially inwardly projecting annular step facing the inner shaft. The at least one annular step may mount the inner shaft with respect to the outer shaft.

Abstract: A laser structuring device for a hub of a valve train component may include at least one load carrier for storing and providing at least two valve train components, at least one laser for laser structuring a hub of at least one valve train component, and at least one robot arm having a gripping device for gripping, positioning and holding the at least one valve train component during the laser structuring. The at least one robot arm may be movable to position the at least one valve train component into a machining position.
