Repair methods for deep groove ball bearing wear
Methods for repairing worn deep groove ball bearings have evolved from offline to online repair. Determining the most suitable technology remains a long-standing challenge. Several common repair methods currently exist:
How to identify the quality of non-standard bearing shafts and gears
Analysis of hobbing accuracy, the accuracy of the shaft teeth is primarily related to motion accuracy, stability accuracy, and touch accuracy. Hobbing uses control of the common normal line length and tooth circle jump to ensure motion accuracy; control of tooth profile error and base pitch error to ensure operational stability accuracy;
Preparatory work for routine bearing inspection
Rotate the outer ring and carefully clean the interface between the cage, rolling elements, and raceway, ensuring that any remaining oil from previous use in hidden areas is thoroughly removed. After cleaning, the bearing should be drained of the cleaning oil, placed on a workbench lined with clean, neutral lining paper to air dry, or slowly dried in a far-infrared oven. From the time the cleaning oil is drained until it is air-dried or oven-dried, the bearing rings, cage, or any rolling elements must not be rotated. The rolling bearing can only be removed from its oil seal packaging and immersed in washing gasoline or acid-free kerosene containing 3% machine oil immediately before it is delivered for routine inspection.
