ferris wheel bearing bearing installation

How to improve the matching precision bearing installation.

In order to improve the matching precision bearing installation, must use the measurement methods and tools do not make the bearing deformation, ferris wheel bearing‍ precision measurement of bearing inner and outer circle with the surface size of the actual project, the measurement can be related to the inner and outer diameters of all be measured, and make a comprehensive analysis of the measured data, the according to precision bearings, matching with the shaft and hole of installation parts. The distribution of shaft and hole in the actual measurement of the corresponding size and geometry, temperature and measurement should be carried out in the bearing under the same.

To guarantee the higher Single Row Ball Slewing Bearing‍ actual tie effect, the shaft and hole matched with a bearing surface, the roughness should be as small as possible.

In the above measurement, should be in the outer circle and bearing inner hole, and the corresponding surface of the shaft and the seat hole, on both sides near the assembly chamfer, respectively two groups of marker can show the maximum deviation direction, so that in the actual assembly, the match two party of maximum deviation of the same orientation so, in the assembly, the deviation can be partially offset.

The purpose of making two sets of directional signs, is the Taper roller bearings‍ deviation compensation can be considered, even supported at both ends of each rotating accuracy improved, and between the two bearing seat hole and the trunnion coaxiality error on both ends are partially eliminated. The mating surface to surface strengthening measures, such as sandblasting, precision plunger diameter slightly larger plug a hole, are beneficial to improve matching precision.
