Definitions
- the invention relates to a method for mounting a first machine part in a second machine part.
- a bearing carrier which must be installed in a housing.
- a bearing carrier main body which is designed to receive roller bearings.
- the bearing carrier is pre-assembled, d. H.
- the bearings are used in cup-like depressions of the bearing carrier body and fixed here.
- the complete bearing carrier is inserted into a round or similarly shaped bore or recess in a housing. So that the bearing carrier has a sufficient hold in the housing during later operation, a press fit between the bearing carrier and the housing bore must be present.
- the required press-fitting of the preassembled bearing carrier in the housing thereby sometimes has the disadvantage that form in the material of the bearing carrier tensions that can lead to tolerance changes. This in turn leads to losses in the quality and durability of storage.
- the invention has for its object to propose a method of the generic type, with which it is possible to gently eliminate occurring during the assembly process stress states in the material of the first machine part. This should be done so that in particular adjacent components - such as in particular heat-sensitive bearings - are not excessively thermally stressed.
- the solution to this problem by the invention is characterized in that the method comprises the steps of: a) installation of the first machine part in its intended end position in the second machine part; b) activating an exothermically reacting substance disposed on, on or in the first and / or second machine part to cause a thermal microstructural change in a part of the first machine part.
- the invention thus aims to subject the first machine part after its installation, a heat treatment in the broadest sense. Tensions resulting from the assembly process itself can be eliminated in the assembled state.
- the exothermically reacting substance can be arranged before or after the implementation of step a) on, on or in the first and / or second machine part; but it is also possible that it is arranged together with the implementation of step a), on or in the first and / or second machine part.
- the thermal structural change is primarily a stress relief annealing. But it is also possible that the thermal structural change is part of another annealing process, for example a soft annealing process. It is also possible that the thermal structural change is part of a hardening, tempering or stabilization process. An example is a compensation process.
- the exothermically reacting substance can be applied as a layer on, on or in the first and / or second machine part.
- it can also be applied to a support element, wherein the support element is then arranged on, on or in the first and / or second machine part. Accordingly, the substance can thus be applied directly to the machine part or indirectly via a carrier.
- the assembly of a bearing support which is mounted in a second machine part in the form of a housing can consist of a reactive nanocrystalline material.
- the triggering of the exothermic reaction in the, for example, reactive nanocrystalline layer can be effected by passing an electric current through the substance.
- the exothermically reacting substance can be applied or applied to the first and / or second machine part as a separate structure.
- the first machine part is designed as a bearing carrier
- at least one circular recess may be provided for receiving the bearing ring of a rolling bearing, wherein the exothermically reactive layer along the circumference of the circular recess or along a portion of the circumference can be arranged.
- the bearing carrier body consists in particular of sheet metal.
- a possible formation of the exothermic substance is one which uses nickel (Ni) and aluminum (Al).
- Ni nickel
- Al aluminum
- the reactive nanocrystalline layers provided are preferably films which have a multiplicity of thin layers which can act as a local heat source.
- Derarti- ge layers are commercially available, for example under the name nanofoil ® from Reactive Nano Technogies Inc., USA.
- Said layer represents a thermally unstable layer, which can be melted upon activation, for example by passage of an electric current. But it is also possible, instead of films to apply the exothermic substance in the form of pasty material.
- the exothermically reacting substances used can be provided as layers, for example by placing or placing said reactive nanocrystalline films.
- the proposed method thus provides a solution with which components - in particular the drive technology - can be heat treated after their assembly.
- the need for this arises mostly through the assembly process itself, d. H.
- During assembly local stresses are generated in the machine part by pressing operations, which can lead to tolerance changes. These are gently removed again by the proposal according to the invention.
- the inventive concept is based on the local application of an exothermic substance, which can be used as a layer or generally in the form of particles. This can be done very targeted and narrow limits a voltage reduction, without affecting thermally sensitive environmental areas or parts (for example, a rolling bearing).
- Stationary heating furnaces for heat treatment are just as unnecessary as mobile heating appliances.
- the proposed method can be easily integrated into an automated assembly process. This also applies to a manual assembly process in which the components can then be lukewarm. Finally, the process can be implemented without high costs.
- the invention proposal can be used in any application.
- the type of heat treatment whether stress relieving or other annealing, tempering, stabilizing and hardening processes - is possible in a wide range.
- FIG. 1 shows schematically a first machine part in the form of a bearing carrier to be installed in a second machine part in the form of a housing, wherein the parts are not yet connected to each other,
- Fig. 2 shows the first and second machine part according to FIG. 1, wherein the parts have now been mounted
- Fig. 3 shows the detail "X" of FIG. 2, in which case an exothermically reacting substance is shown, with which amatsarmglühen.
- a first machine part 1 can be seen in the form of a bearing support to be installed in a second machine part 2 in the form of a housing. Details of the structure of the bearing support 1 and the housing 2 are shown in FIG. 3. Thereafter, the bearing carrier 1 has a bearing carrier base body 4, the cup-shaped recesses for receiving two bearings 5 has. The rolling bearings 5 are fixed in the bearing carrier 1. The entire and so far preassembled bearing carrier 1 is then mounted in a bore 6 in the housing 2 by the bearing carrier 1 is pressed axially into the bore 6.
- FIG. 1 still shows the preassembled bearing bracket 1 prior to assembly in the housing 2, it has been pressed as shown in FIG. 2 in the bore 6 of the housing 2.
- tensions have resulted in the material of the bearing carrier body 4, which are disadvantageous in terms of the quality of storage and their service life.
- the stresses in the material of the bearing carrier basic body 4 are reduced as follows: on the bearing carrier main body 4, in areas where An exothermically reacting substance 3 is applied, as can be seen in FIG. 3.
- An exothermically reacting substance 3 is applied, as can be seen in FIG. 3.
- a second exothermic substance 3 'located which can be used optionally.
- This substance 3 or 3 ' is distributed on the bearing carrier body 4, as it corresponds to the locations of the voltages to be degraded. Subsequently, the substance 3 or 3 'is activated so that an exothermic process takes place, which locally heats the material of the bearing carrier body 4.
