Slewing bearing The actual method with improved accuracy

In order to improve the accuracy of the bearing with the actual installation, you must not make use of measurement methods and instruments bearing deformation of the bearing bore and the outer dimensions of the actual mating surface precision measurement, you can measure the inner and outer diameters of about All items to be measured, and the measured wind turbine bearings data to make a comprehensive analysis of this as far as precision worthy of the shaft and the bearing seat hole the size of the installation site. In the actual measurement with the appropriate size for the hole and the shaft and housing geometry, the measurement should be carried out when the temperature of the Slewing bearing  under the same conditions.
In order to ensure a higher actual match results, and the surface of the shaft and the bearing seat hole match, the roughness should be as small as possible.
In making the measurement, should be in the outer and inner bore of the bearing and the corresponding surface on the shaft and housing bore at both sides close to the chamfer, respectively, showing Ceramic Ball Bearings the maximum deviation can be made in two directions marked so in the actual assembly, so that the maximum deviation of the two sides match aligned in the same direction, so that after assembly, to partially offset the deviation between the two sides.
The purpose of making two Slewing bearing directional signs, that can compensate for deviations into account, even if supported at both ends of each rotation accuracy improved, and the two ends of the seat and the Order of the hole concentricity error between the journal has been part of the eliminated. Implementation of measures to strengthen the surface of the mating surfaces, such as sand blasting, with a diameter slightly larger than the precision plunger plug a hole, etc., are beneficial to improve with accuracy.
