Embodiment Construction

[0033] The same reference numerals are used in the figures for the same or similar components, even if repeated explanations are omitted for reasons of simplification.

[0034] figure 1 An insert 1 according to the invention is shown, which is used as an auxiliary tool for the method according to the invention. The insert 1 itself is designed in the form of a cylinder 2 , wherein projections 4 protrude relative to the outer peripheral surface 3 and center the insert 1 in the corresponding bore 10 or opening. A receptacle 5 is formed in the outer peripheral surface 3 of the insert 1 itself, wherein the receptacle 5 is designed in the form of a recess. A carrier 6 with strain gauges 7 glued thereon is arranged in this receptacle 5 in a recessed manner relative to the outer peripheral surface 3 . The receptacle 5 itself again has two insertion openings 8 , through which a wedge key (not shown here) can be inserted.

Abstract

The method involves cleaning the inner surface of the opening (8). The insert (1) is provided with an outer circumferential surface (3) corresponding to the inner surface of the opening, which is provided with a receptacle (5) in which strain gauge (7) is inserted. An adhesive is introduced into the opening for applying to the strain gauge. The wedge pin inserted in the guide of the insert is engaged under the strain gauge and pressed against the inner surface. The adhesive is partially cured for removing the wedge pin and / or insert from the opening.

Description

technical field [0001] The invention relates to a method for gluing strain gauges into openings according to the features of the preamble of claim 1 . Background technique [0002] Mechanical components, especially steel components, are subjected to intense stresses and the resulting wear during their use. In particular, abrasive wear on surfaces can sometimes already be determined by visual inspection by means of non-destructive material tests. [0003] However, the mechanical stresses present in the component itself cannot be determined directly from the outside. Non-destructive material testing methods also exist for this, but these require rather complex measuring techniques, for example in the case of x-rays or ultrasound, and can also only be carried out when the corresponding machine or component is stationary. [0004] It is therefore known from the prior art, for example from DE 10234626 A1, to incorporate sensors into mechanical components which can monitor the i...
