Abstract: A method may include thermally joining at least one of a non-round functional component to a shaft and a cam to a camshaft, elastically compressing the functional component during introduction of a round through-opening, and creating a through-opening which is not round when the functional component is unstressed and at least minimizes an asymmetrical deformation of the shaft after the thermal joining of the functional component to the shaft.

Abstract: A moveable valve sealing body, especially a valve sealing body of a gas exchange valve of an internal combustion engine, exposed to hot gases and comprising a sealing area that can be applied to a valve seat ring, enabling good heat dissipation outside an oil-lubricated guiding means connected to the sealing body. For this purpose, such a sealing body is characterized in that at least one surface region of the sealing body, which region being exposed to the hot gases, up to maximally directly on the sealing region of this sealing body, is composed respectively of at least one first and one second material (1, 2), wherein the second material (2) overlaps the first material (1) in an externally heat-conducting manner and furthermore has a greater heat conductivity than the first material (1). The second material (2) is applied by means of a thermal spraying method.

Abstract: A heating device for heating a hollow component may include at least one inner induction coil and at least one outer induction coil, each configured to be heated. At least one element may be configured to influence a magnetic field formed between the inner and the outer induction coil during the operation of the heating device. The element may be arranged between the inner and the outer induction coils. Regions of the hollow component may be thinner and the thinner regions may be configured to heat more quickly than the remaining thicker regions. The thinner and thicker regions of the component may allow even heating of the component to be achieved.

Abstract: A casing for a steam or gas turbine comprises a shell and two flanges. The wall thickness of the shell is varied in an upper region facing away from the flange, in two central regions and in two lower regions facing the flanges, such that the upper region facing away from the flanges is reinforced in comparison with the lower regions facing the flanges. The lower regions facing the flanges are more flexible than the flanges which are attached by screws, and the partially reinforced central region and the reinforced upper region, and act as a joint to compensate for deformation, particularly in the radial direction. Consequently, the casing remains considerably more round in operation. The reduced radial clearance (achieved by reduced deformation) between the casing and the ends of the turbine blades leads to considerably increased efficiency during operation of the turbine.
