Km bearing | bearing inner sleeve processing problem, pay attention to yo!

[Abstract]:
When the inner sleeve is processed, the principle and requirements of groove edge chamfering, grinding plane and grinding raceway are similar to those of the outer coat. After the inner ring grinding plane is processed, the centerless inner and outer diameter is processed. This is the foundation of the inner groove branch grinding groove in the next process. The inner and outer diameter grinding process is required to be similar to the outer diameter grinding. Roughing the inner raceway (supporting the inner and outer diameter of the raceway) after grinding the inner and outer diameters. The requirements of roughing the inner raceway are similar to those of the outer raceway. Then roughen the inner diameter. The advantage of doing this is to make the inner diameter, inner raceway and inner and outer diameters concentric, reducing the vibration and noise of the finished bearing. The requirements of fine grinding inner raceway after rough grinding inner diameter are similar to those of fine grinding outer raceway. Then the inner diameter is finely ground and the inner raceway is finely ground (similar to the outer raceway). Bearing assembly surface and matching parts surface, if there is a collision, rust layer, dust, sand, dust and soil, a bearing installation is difficult, resulting in incorrect assembly position; Second, these attachments form abrasives and easily rub out the working surface of non-standard bearings, affecting the assembly quality. Therefore, the surface of the journal, bearing housing shell hole, the end face of the shoulder, and the matching surface of connecting parts such as bushing, gasket, end, etc. should be carefully inspected before installation. If there is a rust layer, you can use a fine file off, polishing fine emery cloth, at the same time, you should also remove the bearing assembly surface and its attachment parts. The inner and outer rings can be separated bearings, do not exchange the outer rings wrong so as not to affect the contact quality. For the non-standard bearing, do not arbitrarily take out the rolling body in the bearing mixed, so as not to affect the accuracy of the installation position. When installing the bearing, to facilitate the inspection of the bearing code, not wrong, the bearing ring should be literally placed and installed outwards.
