Definitions
- the invention relates to a method for calibrating a sensor system of at least one measuring bearing for a warehouse installation, with which individual measured values of an individual storage installation are compared with representative reference values of a reference installation.
- Calibration is an activity for determining the relationship between the output values of a measuring device or a measuring device or the values represented by a material measure or a reference material and the associated values of a measured variable determined by standards under specified conditions.
- DE 199 37 203 A1 provides for the calibration of a measuring bearing during installation.
- a sensor system of strain gauges should determine load components of the bearing based on stresses from the rolling contact. The goal is to calibrate the bearing as realistically as possible. Therefore, it is also intended to perform the bearing calibration of the bearing with a preload in the installation.
- the influencing variables to be measured on the bearing are, for example:
- Such influencing variables are always superimposed by disturbance variables in real individual installation.
- Disturbance variables are, for example, also the ones which can also be assigned to the group of the aforementioned influencing variables.
- these disturbance variables have a disadvantageous effect on the result of the calibration process, that is also on the measured values, since these can falsify the measurement result.
- Measured values are variables resulting from the influences, such as voltages from overlaps.
- the reference values created for the measured values are standard values, which are determined on the basis of a representative group of individual values.
- the reference values have the same physical unit as the concrete measured values.
- the bearing defined in the installation is rotated and thus taken into account relatively accurately during the adjustment of the dead weight of the structure to be stored. For example, the influence of interference fits from the bearing seat is not included in the reference value.
- the object of the invention is therefore to provide an easy-to-implement method for calibrating the sensor technology of a measuring bearing, in which the influencing variables on measured values of the bearing during calibration are taken into account as realistically as possible.
- the invention provides a method for calibrating a sensor system of at least one measuring bearing for a storage installation, in which individual measured values of an individual storage installation are calibrated with representative reference values of a reference installation prior to the installation of the measuring bearing. It is essential that the installation conditions are simulated on the not yet built into the machine, the transmission or the like bearing and then the sensor is calibrated.
- Rolling bearings where the measuring effect is influenced by the overlapping of the inner and / or outer ring with the corresponding bearing seat, are calibrated before installation in the bearing seat.
- Overlaps are the intended differences in diameter with which an interference fit is produced on the bearing seat. These overlaps result in stresses in the bearing ring. These voltages are superimposed or distorted on the built-in bearing u. U. the voltages from the rolling contact. If, during operation of the bearing, for example with a sensor system made of strain gauges, the stresses from the rolling contact are to be determined, the influences of the interference fit during calibration are taken into account according to the characteristics of the method according to the invention.
- the interference fit is simulated by means of a mandrel.
- the interference fit is simulated, for example by means of a collet or a clamping ring.
- the method according to the invention makes it possible to produce pre-calibrated measuring bearings, measuring bearing systems and bearing units, even at the bearing manufacturer.
- the individual cost-intensive calibration and also checking the functionality of the bearing on the assembly line at the customer can be omitted. It is possible to have clear assignments of responsibilities e.g. with a view to possible warranties between customer and supplier.
- the individual influencing variables are normally within a tolerance range.
- the permissible tolerance field is determined on the basis of necessary production and assembly-related tolerances. For example, if the manufacturer of the measuring bearings does not have concrete bearing installation values, such as the inner diameter of the housing seat or the outer diameter of the shaft seat for the measuring bearing, then the manufacturer of the measuring bearing will deliberately produce classes of calibrated bearings. First of all, the tolerance field between the permissible maximum and minimum values is divided into a defined number of groups. Then the proportion of influencing variables that can be determined on the bearing to be calibrated is determined. Afterwards, an installation is simulated at the warehouse, taking into account one of the groups, and the bearing is calibrated. The bearing is sorted into a class of calibrated measuring bearings related to the respective group. Before installing the measuring warehouse into the concrete installation, the concrete value of the installation is determined, assigned to the corresponding group and then sorted out of the corresponding class by means of the group of measuring bearings.
