In order to improve the actual fitting accuracy of the bearing installation, it is necessary to use the measuring method and the measuring tool which do not make the bearing deformation, to carry on the actual precise measurement to the inner and outer cylindrical matching surface dimensions, and to measure the inner diameter and outer diameter All the items to be measured, and to make a comprehensive analysis of the measured data, as a basis, precision with shaft and seat hole for the installation of the size of the bearing. In the actual measurement of the shaft and seat with the corresponding hole size and geometry, should be measured with the bearing at the same temperature conditions.
In order to ensure a high degree of actual matching effect, the shaft and seat bore matching surface with the bearing, the roughness should be as small as possible.
At the time of this measurement, two sets of indicia, which indicate the direction of maximum deviation, shall be made on the outer and inner bores of the bearing, and on the corresponding surfaces of the shaft and seat bore, on both sides near the fitting chamfer, In the actual assembly, so that match the maximum deviation of the two sides aligned with the same orientation, so that after assembly, the two sides of the deviation can be partially offset.
The purpose of the two groups of directional signs is that the compensation for the deviation can be considered, even if both ends of the bearing rotation accuracy has been improved, but also between the two bearings between the hole and the end of the axis of the coaxial error is partially eliminated . Surface with the implementation of surface strengthening measures, such as sand blasting, with a slightly larger diameter of the plunger plug a precision hole, etc., are conducive to improving the accuracy of the match.
