YOGIE bearing thinks: in order to improve the actual coordination accuracy of bearing installation, must not make bearing deformation measuring method and measuring tools, the bearing surface of the inner hole and cylindrical coordinate measure precision of the actual size, can be related to inner and outer diameter measuring project all be measured, and make a comprehensive analysis of measured data.
In the actual measurement of the corresponding size and geometric shape of the shaft and socket, it should be carried out under the same temperature conditions as when measuring the bearing.In order to ensure a high practical matching effect, the matching surface of shaft and seat hole and bearing, its roughness should be as small as possible.When measuring above, should be on the bearing outer circle and inner hole, as well as the shaft and hole corresponding to the surface, near the sides of the assembly chamfering can respond in Ming direction of maximum deviation of two sets of tags, so that when the actual assembly, make suitable maximum deviation on the same position of the two parties, so after the assembly, the two sides to partially offset the deviation.The purpose of making two sets of directional marks is to give comprehensive consideration to the compensation of the deviation. Even if the rotation accuracy of the two supports is improved, the coaxiality error between the two supports and the two ends of the journal can be partially eliminated.The surface strengthening measures for the mating surface, such as sandblasting and inserting the inner hole of a precise plunger with a slightly larger diameter, are conducive to improving the mating precision.
