In this manner, thermal stress and, also, a resulting component distortion are minimized.

You reduce the component distortion and avoid extensive reworks thanks to the low heat input.

These include good automation, low component distortion and the ability to do without welding fillers.

Due to the low heat input, the energy requirement and the component distortion reduce considerably.

Due to the low heat input the component distortion is reduced to a minimum.

The low heat input considerably reduces the component distortion.

You reduce the component distortion and avoid extensive reworks.

The intended result is a more uniform cooling of the individual layers and, consequently, less component distortion.

Moreover, distortion of the part, caused by concentrated local introduction of heat, is so minimal that it is hardly measurable.

The selective laser sintering carried out according to the present invention reduces component distortion since the temperature distribution within a layer of the deposited powder cake is homogenized better and decreases more uniformly, starting from the sintered regions of the surface down to the bottom of the design space.

Laser cutting, in comparison with other thermal cutting techniques, is known for its high precision, high cutting speeds, low heat input and low component deformation.

This special welding process impresses thanks to its energy efficiency, low component distortion, and high productivity, and requires no filler metal.

According to another advantageous feature of the present invention, distortion of the component is prevented or the use of an additional holding device becomes unnecessary by eliminating a solution annealing treatment with subsequent quenching.

Thereby, the heat is released to the outside as less as possible, and on the other hand, distortion of the three-dimensional body is avoided.

A small or limited temperature increase can advantageously minimize a possible component distortion of the receiving hook and of the entire housing.

As the application of polyurethane—another thermoplastic elastomer can be used in the same way—involves heat, the different coefficients of thermal expansion of the support and the roof cladding element may cause stresses or an uncontrolled component deformation with negative effects on the function and the visual qualities of the component as a whole.

Accordingly, only the component deformation associated with case hardening remains, said component deformation being comparable with corresponding deformation during the production of large transmission gearwheels configured in one piece and accordingly being able to be controlled.

The component deformation, which is not able to be avoided during the case hardening, may be minimized by a suitable choice of shape and position of the recesses.

Moreover, the quenching means is distributed uniformly during the quenching process, such that it is possible for the temperature distribution in the individual regions of the large transmission gearwheel to be as uniform as possible during the cooling and/or quenching, whereby component deformation is effectively counteracted due to local temperature differences.

Problems can here be encountered with regard to the temperature distribution given multilayer constructs, which can lead to component distortion and an elevated pore content in the laminate.

Therefore, with an inventive method, the danger of component distortion occurring is minimised and the components produced according to the invention are characterised by particularly high dimensional accuracy.

During this process, a large amount of energy is introduced into the component which, during the quenching process, may lead to significant component deformation.

This component deformation has to be compensated both in advance by costly structural measures and retrospectively by a corresponding removal of material.

In spite of these expensive and complex countermeasures, however, in practice it is only possible with difficulty to restrict the component deformation to limited regions and in a controlled manner.

This method has the advantage that only a relatively small amount of thermal energy is introduced locally into the component, whereby a high level of component deformation is prevented.

In large transmission gearwheels a relatively low level of component deformation already leads to considerably greater deviations in shape than in small gearwheels, due to the relatively large dimensions, in particular the large diameter of the gearwheel.

Due to the dimensions in small gearwheels, deviations arising from component deformation lead to fewer deviations of shape than in large transmission gearwheels which is why in hybrid large transmission gearwheels the aforementioned problem of deformation introduced into the component by welding and hardening only plays a minor role, in particular if only lower grade materials are required for the gear teeth as they are used in the context of fatigue strength.

The present invention is based on the surprising recognition that by combining a beam welding method and case hardening only a small degree of component deformation is associated therewith, which may be compensated at low cost during the course of the subsequent hard machining step, without a large allowance having to be made therefor.
