In order to improve the actual installation of the INA Bearings with the precision, must take advantage of the INA Bearing deformation measurement methods and measurement tools, the actual precision measurement with surface dimensions of the bearing bore and cylindrical, can be the inner and outer diameters all measurement items to be measured, and to make a comprehensive analysis of the measured data, as according to the size of the installation position of the precision with doing the bearing of the shaft and housing bore. In the actual measurement with doing the corresponding shaft and housing bore dimensions and geometry, and measurement of bearing the same temperature conditions.
In order to ensure higher with the effect of the shaft and seat hole and INA bearings to match the surface roughness should be as small as possible.
Do these measurements should be in the cylindrical bore of INA bearings, as well as corresponding to the shaft and housing bore surface, near the assembly chamfer on both sides, respectively, to make two sets of markers that indicate the maximum deviation of the direction of so that the actual assembly to match the two sides, the maximum deviation at the same position, so that after assembly, the two sides of the deviation can be partially offset.
Purpose to make two sets of directional signs is to compensate for the deviation can be taken into account, even if both ends of the bearing rotation accuracy is improved, and also allows the seat between the two bearing holes and both ends of the journal, the concentricity error be partly eliminated. With the surface of the implementation of surface hardening measures, such as sandblasting, with a diameter slightly larger than the precision plug column to insert the plug once bore, are beneficial to improve the fitting accuracy.
