Invalid adjustment mode of rolling bearing stuck<br>Contact fatigue failure refers to the failure of the working surface of the bearing due to alternating stress.. contact fatigue peeling occurs on the bearing surface, which is often accompanied by fatigue cracks. The first maximum alternating shear stress is below, and then extends to different peeling shapes, such as pitted surface or pitting peeling, which is called shallow peeling. Because the development of spalling surface gradually becomes to expand, but often to the deep expansion, forming a deep spalling. Deep peel contact fatigue source of fatigue failure.<br>State when the bearing is jammed<br>1. For the cylinder, ellipse and the side clearance of the bearing bush, the traditional manual grinding and scraping method or the method of repairing and scraping after the split surface and pad turning in the bearing system can be used for adjustment.<br>2. The top clearance of cylindrical and elliptical bearings, if possible, can be adjusted by hand scraping or adding pads to the surface of the bearing.<br>3. In principle, for multiple fixed wedge bearings, it is allowed to repair the high-speed temporary storage and adjust the clearance, which shall not be properly replaced by the new bearing.<br>4. For multi wedge tilting bearing pads, it is not allowed to repair and scrape the pads. If the clearance is not qualified, the pad shall be replaced timely. The thickness of the adjustable pad can be adjusted by adjusting the amount of W added to the stainless steel pad block of the rear block, thinning or adjusting the thickness of the block. Pay attention to the deviation of the thickness of the tilting bearing bush with multiple oil wedges between the same set of tiles should be less than 0.01mm.<br>The main cause of bearing failure is defect and overload. When the applied load exceeds the strength limit of the material, the parts are called overload fracture damage. The overload is mainly caused by the sudden failure of the host or improper installation. The micro crack, shrinkage cavity, bubble, bulk foreign matter and local overheating of the structure of the bearing parts may cause severe vibration or impact overload burn at the time of the fracture defect, which is called fracture defect.
