Surface of the outer spherical bearing parts rough requirements are standard and process, but in grinding and superfinishing process, for various reasons, often do not meet the prescribed requirements. We can check the SKF bearing surface roughness to determine the accuracy and quality of the original bearing.
Causes for bearing the workpiece surface roughness is not up to the requirements of the main reasons is very important, it is divided into several parts to introduce:
1 lathe outer spherical bearing rigidity problems such as the plug iron loose, transmission disequilibrium caused by vibration. Of course, lathe FAG bearing installation instability will cause vibration, the vibration caused by the surface roughness of the workpiece is reduced.
2 bearing rigidity problems caused by vibration so as far as possible, use coarse knife rod, reduce NSK bearing length; the shortage will cause vibration, the application frame in turning slender shaft, or with a clip of a top instead of the two top clamping.
3 bearing its geometry parameters is not correct according to the cutting angle cutting characteristics, reasonable selection of appropriate of the workpiece material, the surface roughness decreases.
4 due to accumulated chips, so that the workpiece surface roughness decreased built-up very firmly, cutting the bue participation, to enable the TIMKEN bearing surface appearance of napping or a designated groove mark phenomenon, turning bearing should be avoided when the. Combined with analysis of the above reasons, should accomplish early know early prevention processing, to the problem nipped in the bud, to improve the bearing precision, meet the design requirements.
Outer spherical bearings in the grinding process, its surface is carried out through the high-speed rotation of the grinding wheel, the grinding if not according to the operating instructions and adjust equipment, will all kinds of defects in INA bearing working surface, so as to affect the overall quality of bearing. We can check the quality of bearing according to this.
