the invention is aimed at having sensors in the body or casing and auxiliary gearbox elements to measure their local deformations and the forces the axes and bearings of a rotary machine are subjected to in general and particularly those of a gearbox , forces that are transmitted via the axes , supported at the same time by these bearings . the forces withstood by the axes are transmitted to the bearings by contact and similarly , the bearing forces to their supports . sensorization can be carried out in both the rotating shaft and in the bearings or their supports , in other words , structure , locking covers , flanges or other mechanical lift systems . another objective of the invention is determining the number of sensors and places they are positioned in so that the measures obtained are both in the direction of the shaft or axial , and in the direction of the radius or radial in the suitable direction , obtaining the radial and axial forces instantly and simultaneously and managing this data at all times . another objective of the invention is integrating these sensors in the rotary machine , and these sensors can be implemented on elements subjected to continuous movement , measuring local and general deformations of the bearings the rotating shafts are supported on . another objective of the invention is obtaining an accurate measurement of the control system and its management for different machine states and temporary events , such as different load and speed levels , operating starts and stops , pauses , emergency stops , one or more pitch control of blades , r . p . m . adjustment , temporary transients due to running or operating loads in the machine , as well as different hypotheses present in component designs . the advantages provided by the system subject to the invention can be extracted from the previous description : thanks to the slender but robust design of the sensor structure and the rounded shapes in the sensitive elements localization points , a good signal response to the traction - compression axial loads is found in the direction of the shaft supported by the bearings and to the radials in any diametric direction perpendicular to the shaft symmetry of the shaft supported by the bearings . in spite of making the sensor &# 39 ; s structure more flexible to incorporate the sensitive elements , the equivalent rigidity of the assembly does not suffer any appreciable variations , and therefore the distribution of forces in the different sensorized shaft supports is unaltered . fig1 is a general view of the gearbox where the layout of the axes and parts the sensors are coupled to can be seen . fig2 is a section corresponding to the end of the gearbox &# 39 ; s intermediate shaft , showing bearing , sensor , auxiliary part , casing and cover layout . fig3 corresponds to one of the possible designs of the gearbox &# 39 ; s bushing , on which the sensors measuring the radial forces transmitted by the rotating shaft are installed . fig4 shows the intermediate shaft cover with the detail of the peripheral ribs that measure the axial forces transmitted by the aforementioned rotating shaft . the shaft or axes whose reactions are going to be measured are supported on two or more bushes or bearings that transmit the radial and axial forces to the gearbox casing or body . the intercalation of the sensorized components allows for measuring these radial and axial forces . as shown in fig1 , the gearbox is made up of a general body ( 1 ) coupled at one of its ends to a rotor hub ( 2 ) and by the other to a generator ( 3 ) not shown in the figure . the side joined to the generator ( 3 ) is covered by a casing ( 7 ) with three main rear covers : main shaft cover ( 4 ), intermediate shaft cover ( 5 ) and quick shaft cover ( 6 ). the gearbox &# 39 ; s axes and bearings are inside the casing that cover and protect the aforementioned covers . in fig2 , the housing where the intermediate cover ( 5 ) is sectioned and the gearbox casing can be seen inside it ( 7 ) in a top plan . underneath it is a bushing ( 12 ) where the radial sensor elements are included ( 8 ) next to the bearings ( 9 ). it is in this cover ( 5 ) where the axial sensor elements are placed in machined ribs ( 10 ) for this purpose on its periphery . the methodology applied to obtain the sensorization system that is the objective of the invention , is replacing the shaft support elements ( 11 ) and bearing with a set of elements including the sensor bushing ( 12 ), specific bearing ( 9 ), auxiliary parts ( 13 ) and cover ( 5 ) that reproduce the original geometry and functions . the auxiliary parts ( 13 ) are installed between the shaft ( 11 ) and the bearing ( 9 ) to fix and center the two elements . a bushing ( 12 ) is used to measure the radial loads which have the sensor elements ( 8 ) tangentially and radially according to the loads to be measured . fig3 shows a detail of this layout . to measure the axial loads , a distribution distributed around a cover ( 5 ) has been chosen , in which some ribs ( 10 ) have been machined according to axial plans to position the sensor elements . fig4 shows the specific location of the axial sensor elements ( 14 ) for sensor ( 8 and 14 ) dimensioning and the determination of the optimum measuring points of the sensor elements , their structural response is calculated with theoretical and / or virtual simulation analyses , such as the finite element method , in order to assess both the rigidity and the resistance of the sensor . the sensor elements may be extensiometric , piezoelectric , capacitive , resistive , fiber optics or other sensory technologies . the layout and assembly will depend on this technology . the sensor elements will be installed in the previously determined measurement directions according to the magnitudes to be measured and the results of the preliminary theoretical analyses and simulations to obtain the axial and radial sensor . sensor assembly will be carried out adapting the new set of elements to the gearbox &# 39 ; s general assembly specifications , so that there are no substantial modifications in the distribution of forces . the sensors are finished off with the electronics required for signal conditioning and treatment .
