DETAILED DESCRIPTION OF THE INVENTION

[0017] There follows below a detailed description of a preferred embodiment of the present invention, by way of example and in no way limiting. Nevertheless, it will become clear to a technician skilled on the subject, upon reading this description, possible further embodiments of the present invention still comprised by the essential and optional features below.

[0018] The destructive and generally unfeasible test is replaced by another one that is easy to apply, by means of the use of the equipment described below, associated with its electromechanical actuators. Therefore, the difficulty of performing some tests is eliminated by the application of this invention.

[0019] The present invention replaces an extensive test, with risk of catastrophic failure and generally unfeasible, with a non-destructive and short duration test. The mentioned test deals with the determination of mechanical properties and simulation of defects in any rotating machines.

[0020] The modular structure for fixing radial electromagnetic actuators for non-destructive testing and failure simulations in rotating machines without disassembly of bearings comprises the following components: ferromagnetic core (1), armature (4), cover (6), cell load (10), upper reinforcement (15), lower reinforcement (16), lower plate (17), side plate 1 (18), side plate 2 (19), upper plate (20), beam (7), spool (2), adjustment 1 (11), captive pin (3), chassis (5), lock (8), plate (9), adjustment 2 (13), captive bolt (12), adjustment 3 (14).

[0021] The assembly of these components is detailed in the figures at the end of the document. The proposed device is divided into 4 sets, with distinct and clear functions:

1. Active components—generate the electromagnetic forces applied to the machine shaft;
2. Adjustment components—allow positioning with fine angular and radial adjustment of the active components in relation to the internal structure;
3. Internal structure—keeps the active and adjustment components in their proper positions in relation to the machine shaft;
4. External structure—acts as a protection structure for the other components of the device proposed herein and as a reference position for the load cells.

[0022] The structure begins to be assembled by joining the active components with the internal structure. The device is partially mounted outside the machine to be studied, so that three ferromagnetic cores (1) are positioned on the chassis (5). After this process, the covers (6), of north and west positions, are mounted on the ferromagnetic cores (1) mounted on the chassis (5), and fastened by screws, which have their heads seated on the covers (6) and threaded into the chassis (5). Once this is done, the beams (7) are fixed to the chassis (5) by means of the locks (8). The load cells (10) are then screwed to the upper plate (20) and to the side plate 1 (18), which are positioned around the structure assembled in the previous step by means of the introduction of beams, previously fastened to the chassis (5), in the slots in the upper plate (20) and side plate 1 (18). Then, the components of the internal structure are fixed to the upper plate (20) and side plate 1 (18) by means of load cells (10). The plates (9) are screwed to the load cells (10), and are fastened to the beams (7) by means of the locks (8).

[0023] Part of the external structure is mounted outside the machine. The side plate 1 (18), side plate 2 (19) and upper plate (20) are fixed together. The lower plate (17) is fixed to the rotating machine rail and the previously assembled set is positioned on the machine through the slot present in the chassis (5). The lower plate (17) is fixed to the side plate 1 (18) and the side plate 2 (19) by means of a screw joint. The remaining ferromagnetic core (1), positioned at the location of the diagonal slot in the chassis, is assembled and the covers of south and east positions (6) are positioned over the ferromagnetic cores (1) and fastened to the chassis (5).

[0024] Adjustment components are positioned on the anterior portion of the chassis (5) and over the covers (6). First, adjustments 1 (11) are fixed. Captive screws (12) are threaded in adjustment 3 (14) and have their heads seated in the recess in adjustment 1 (11). Then, adjustment 2 (13) is positioned over the set of captive screws (12) and adjustments 1 (11), being then screwed to the chassis (5) and/or covers (6). Finally, the upper reinforcements (15) are fixed to the side plate 1 (18), side plate 2 (19) and the upper plate (20). The lower reinforcements (16) are fixed to side plate 1 (18), side plate 2 (19) and lower plate (17).
