SKF bearings are all very familiar with Germany bearing, in the course of using, we must pay attention to many problems. In the previous part I has been said on the issue. See below and there are problems, we must pay attention to.
1, precision SKF bearing to match parts request
Precision precision of the SKF bearing itself within in the 1 μ m was asked to do so with their matching parts (retaining ring, axis, end covers, housings, etc) shapes and very high size precision, particularly with precision control and bearing the same level, which is crucial, and could most easily be ignored.
If SKF bearings matched parts do not meet these requirements, makes precision bearings are several times larger than the original bearing error occurs after installation, even more than 10 times the error, completely not the precision bearings, matched due to mechanical error is usually not simply superimpose themselves over the bearings on the error, but in multiples of different magnification added.
2, ways to improve the actual fitting accuracy
Use of SKF bearing deformation measurement method and measurement tools, you can improve the actual fitting accuracy of bearing installation. On the mating surfaces of the bearing inner and outer circle dimensions for precision measurements of actual, items relating to measurement of the inner diameter and outer diameter will be measured in their entirety, and comprehensive analysis of measured data, this precision blending shaft and bore dimensions of the bearing mount. Actual measurements of the distribution geometry of the shaft and the bore of the appropriate size and shape, should be the same as when measuring the bearing temperatures.
In for above measurement Shi, should in bearing of outside circles and within hole Shang, and axis and block hole of corresponds to surface Shang, in near Assembly down corner of on both sides of, respectively made can shows out maximum deviation direction of two group mark, to in actual Assembly Shi, makes match two party of maximum deviation alignment same azimuth, such in Assembly Hou, both of deviation to part offset.
