marine crane bearing roller bearing installation

How to improve the matching precision cross roller bearing installation.

In order to improve Thin section bearings‍ the matching precision crossed roller bearing installation, must use the measurement methods and tools do not make the bearing deformation, 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 according to this, precision, matching with the shaft and hole of shaft

The installation part size. self aligning bearing‍ 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 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 cross roller 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 indicate the maximum deviation direction, Crossed Roller Slewing Bearing‍ so that in the actual assembly, so that the large deviation match two party aimed at the same azimuth, in this assembly, both of deviation to partially offset.
