detailed Description of the drawings

In the 1 and 2 shown balancing or calibration device 1 Two points to the ground 2 supporting receptacles or bearing housings 3 . 4 for each a sensor bearing 5 . 6 on, with the arranged on the left in the drawing sensor bearing 5 as floating bearing and the sensor bearing arranged on the right 6 is designed as a fixed bearing.

In the sensor bearings 5 . 6 are known per se and therefore not shown sensors for force F, temperature T and structure-borne noise K integrated with the microelectronic signal preprocessing or a microcomputer, which also in the sensor bearings 5 . 6 are integrated, are technically connected.

Preferably, said sensors are the sensor bearings 5 . 6 are manufactured according to known technologies of micromechanics and microelectronics and are supplied with an electrical voltage, which are used for the force sensors strain-sensitive resistance bridges.

Both sensor bearings 5 . 6 carry a test wave stored there 7 , These are the sensor bearings 5 and 6 installed in a standardized or later installation conditions simulating installation environment. In this respect, it is appropriate, the bearing housing 3 and 4 as well as the wave 7 standardized with defined Maßüberdeckung or according to the installation conditions of the specific application form.

The wave 7 is further by means of a designed as a pressure medium operable piston-cylinder assembly actuator 8th acted upon by an axial force F _A1 . This axial force F _A1 is by means of a force sensor 9 measurable and by a suitable control and regulating device 10 adjustable. This control and regulating device 10 includes signal amplifiers and acts on switching valves, with which the actuating pressure for the actuator 8th is adjustable.

The control device 10 is indicated by the dot-dashed and dashed lines, as well as those in the sensor bearings 5 . 6 integrated sensors for force F, temperature T and structure-borne noise K and the signal preprocessing or microcomputer electrical or non-contact by infrared, ultrasound or radio with an electronic storage and computer unit 11 connected, which in turn present a control panel 12 having an input and output unit.

In addition, the sensor bearings are in the immediate vicinity 5 and 6 radially acting actuators 8th , comparable to the type described above, arranged in such a way that through each of them a radial force F _R1 , F _R2 on the shaft 7 can be applied. The radial forces F _R1 , F _R2 are present in each case via a bearing housing 3 . 4 including sensor bearings 5 . 6 spanning rigid bridge element 13 from the actuators 8th on the wave 7 transfer. Insofar stand the sensor bearings 5 and 6 or the wave 7 during a calibration or calibration process to be performed.

What the actuators 8th As regards the presently hydraulically operated piston-cylinder arrangements, these are based on a hydraulic oil circuit known per se 14 with an oil reservoir 15 , a motorized oil pump 16 and corresponding oil lines 17 connected, wherein the respective desired oil pressure for generating the axial and / or radial forces F _A , F _R as described above by means of the control and regulating device 10 is adjustable.

In order to be able to simulate certain ambient conditions, such as fluctuations in the ambient temperature T _U , a so-called climate chamber is provided in which at least the sensor bearings 5 . 6 arranged and accordingly in the particular desired dimensions are temperature controlled (not shown). In this climate chamber, other environmental conditions such as humidity are adjustable.

The further description of the invention will now be described with reference to a method for calibrating or calibrating the signal preprocessing means at the sensor bearings 5 and 6 ,

Thus, the adjustment and / or calibration of the signal preprocessing means becomes the sensor bearing 5 . 6 preferably carried out in such a way that initially a mechanical and electrical adjustment of the calibration or calibration 1 to the respective sensor bearing 5 . 6 done by type-specific change parts of the device. Subsequently, the sensor bearings 5 . 6 including wave 7 in the adjustment or calibration device 1 inserted and electrically connected, as well as the same closed or secured.

Thereafter, the desired calibration and / or calibration program and the measuring range values are selected via the control panel 12 the storage and computer unit 11 with the result that by means of actuators 8th a defined axial force F _A1 and in each case a defined radial force F _R1 , F _R2 in the immediate region of the two sensor bearings 5 and 6 on the wave 7 be applied. The selected axial and radial forces F _A1 , F _R1 , F _R2 preferably correspond to the dynamic load capacity C _o or C of the sensor bearings 5 and 6 , Of course, the axial and radial forces F _A1 , F _R1 , F _R2 can also have deviating values.

Now computer-controlled a two- or Mehrpunktkalibrierung and / or an adjustment of the waveforms of the sensors at a defined ambient temperature T _U by reading and permanent storage of correction parameters in the signal pre-processing means or the microcomputer, which in the respective sensor storage 5 respectively. 6 is integrated.

In the specific case, this is done in such a way that the applied forces (axial and radial forces F _A1 , F _R1 , F _R2 ) with the calibrated force sensors 9 . 25 in the immediate vicinity of the test object at the sensor bearings 5 . 6 recorded as well as the electronic storage and computer unit 11 where these readings are taken with the outputs of the sensors in the sensor bearings 5 . 6 compared and corresponding Adjustment or calibration routines are processed.

Derived therefrom Abgleidiparameter, such as an offset and / or a gain correction, then the signal preprocessing means of the sensor bearings 5 . 6 forwarded and stored there. As a result, the respective sensor bearings deliver 5 and 6 then standardized output signals for the specific force measuring and temperature range of the same, which allows the use of such a measuring bearing uncomplicated replacement in terms of their dimensions, measuring ranges and output signals, for example, in case of a defect.

In that regard, it is considered useful if the sensor bearings 5 . 6 provide standardized output signals with, for example, electric currents of 4 to 20 mA at the amplifier output via said specified force measuring and temperature ranges. In this case, according to a two-point calibration, the measuring range initial value with respect to the force corresponds, for example, to an output signal of 4 mA and the measuring range end value preferably corresponds to an output signal of 20 mA. In addition, the waveform of the sensor bearings 5 . 6 be linearized by a multi-point calibration or application of interpolation. The parameters to be determined in the calibration or calibration process for carrying out such an interpolation method stored in the signal preprocessing means or microcomputer in the sensor bearing are provided by the memory and computer unit 11 to pass on to them.

It is also meaningful and is detected by the invention that a two- or multi-point calibration and / or the adjustment of the signal waveforms for the compensation of temperature drifts of the output signals (force measurements) for a plurality of representative ambient temperatures T _{U is} performed, which advantageously already above explained Klimaschrank application can find.

In addition to the above-described reading and permanent storage of correction parameters in a microcomputer or signal processing means in the respective measuring bearing 5 . 6 Further methods for electronic calibration or for adjusting the measuring bearing sensors make sense. For example, this calibration can also be carried out by changing electrical resistance cascades on the sensors by means of laser cuts, scoring markers or the like known per se or else by severing leads from electrical resistance cascades by means of said laser cuts or scoring markers.

At the above method steps is followed by a review of measures implemented to, so a review of Calibration or adjustment at room temperature, linearization and / or the compensation of a temperature drift.

When Furthermore, it is advantageous to assess, if a review of the Structure-borne sound sensors connects, by giving these with representative ones Measured variables of Border patterns, which in turn are the worst part of the good and the Defining the best bad part is compared.

Finally, a label of each calibrated sensor bearing 5 . 6 provided with a unique identifier such as a bar code, which in turn may be associated with the simultaneous creation of a corresponding calibration or calibration protocol, and with the removal of the sensor bearings 5 . 6 from the calibration or calibration device 1 ,

According to the embodiments described above, the axial and radial forces F _A1 , F _R1 , F _R2 engage the shaft 7 at. But it is also possible that such forces simultaneously or alone position directly on the sensor bearing 5 . 6 and / or on the bearing housing 3 . 4 attack, in the context of the invention, the adjustment and / or calibration of the sensors or the signal pre-processing means to the sensor bearings 5 . 6 perform.

Furthermore, it should be noted that said balancing or calibration device 1 as described herein as stationary, for example, as the bearing manufacturer firmly stationed device is formed, wherein the sensor bearings 5 . 6 in for example standardized bearing housing 3 . 4 pressed in and onto a standardized shaft 7 be pressed on. Similarly, customer-side bearing housing 3 . 4 and waves 7 in the balancing or calibrating device 1 Use, whereby the above-mentioned concrete installation conditions are well simulated.

On the other hand, there is also a mobile balancing or calibration device 1 conceivable with easily manageable system components, which are preferably provided with standardized mechanical and electrical interfaces and can be flanged to a customer application (not shown in detail).

The embodiment according to the 3 and 4 differs from the above embodiment essentially in that here the balancing or calibration device 1 a sensor bearing to be adjusted and / or calibrated 18 with radially loaded outer ring 19 includes, which of a wave 20 (Test wave) men, who in turn are in a two rolling bearing 21 bearing common bearing housing 22 and one the sensor bearing 18 receiving, in the present case separately formed bearing housing 23 is mounted rotatably drivable. To drive the shaft 20 is at its other end a drive motor 26 with intermediate coupling 27 intended.

The outer ring 19 of the sensor bearing 18 is here by means of three with equal angular distribution over the shaft 20 arranged actuators 24 via force sensors 25 With radial forces F _R resilient, the actuators 24 the actuators described above 8th can match ( 4 ). Further, the wave 20 at the sensor bearing 18 adjacent shaft end by means of another actuator 24 axially loadable with an axial force F _A , via the further force sensor 25 on the wave 20 acts.

The control and regulation of the actuators 24 and operating this balancing or calibration device 1 takes place as described above in connection with 1 and 2 described. Similarly, the connection of the same and the sensor bearing 18 to the memory and computer unit not shown here 11 be realized as already described.

By the in 3 and 4 As shown, it is possible to use the outer ring 19 to load radially such that one on the circumference of the outer ring 19 largely equally distributed radial force F _{R is} generated to the sensor bearing 18 mechanically as evenly as possible in all directions.
