Rolling bearing appears to be stuck and invalid adjustment method <br>2020-04-24 10:35 <br>Contact fatigue failure refers to the failure of the bearing working surface due to alternating stress .. Contact fatigue spalling occurs on the bearing surface, which is often accompanied by fatigue cracks on the contact surface , The first maximum alternating shear stress is below, and then expand to different peeling shapes, such as pitted pitted surface or pitting peeling, peeling into small pieces is called superficial peeling. As the development of the spalling surface gradually becomes enlarged, it often expands deeper to form a deep spalling. The deep peeling of fatigue damage contacts the source of fatigue. <br><br>When the bearing is stuck, the state <br><br>1. The cylindrical and elliptical shapes and the side clearance of the bearing pad can be adjusted by the traditional manual scraping or splitting method in the bearing system. <br><br>2. The top clearance of cylindrical and oval bearings can be adjusted by hand scraping or adding pads on the surface of the bearing if the situation permits. <br><br>3. For multiple fixed wedge bearings, in principle, it is allowed to repair the high-speed temporary storage and adjust the gap, which should not be replaced with new tiles. <br><br>4. For multi-wedge tiltable bearing pads, it is not allowed to repair the pads. If the clearance is not satisfactory, the pads should be replaced at the appropriate time. The thickness of the adjustable pad can be adjusted by adjusting the amount of W added to the stainless steel liner block of the rear block, thinning or adjusting the thickness of the block. Note that for multi-wedge tiltable bearing pads, the thickness error between pads in the same group should be less than 0.01mm. <br><br>The main reasons for bearing failure are defects and overloads. When the applied load exceeds the strength limit of the material, the parts are called overload fracture and damage. The cause of overload is mainly through the sudden failure of the host or improper installation. Micro-cracks, shrinkage cavities, air bubbles, bulk foreign objects, and local overheating of the tissue may cause defects such as severe vibration or impact overload burn during the time of the fracture defect, called fracture defect.

Rolling bearing saline card injury invalid adjustment mode <br>2020-04-24 10:35<br>Contact fatigue failure refers to the failure of the bearing working surface due to alternating stress: Contact fatigue peeling occurs on the bearing surface, on the contact surface or often accompanied by fatigue cracks, the first maximum alternate shear stress below, and then extends to different peeling shapes, such as point-shaped pitted surfaceors or pitting peels, peeling into small pieces called shallow peeling. As the development of peeling surface gradually becomes an expansion, and often extends to the deep, forming a deep peeling. Fatigue destroys the deep peeling contact fatigue source.<br><br>State in case of bearing card injury<br><br>1, the cylinder and oval and shaft tile side gap, can be used in the traditional manual research scraping or bearing system after the split pad turning method to adjust.<br><br>2, cylindrical and oval bearing top clearance, if circumstances allow, can be hand scraping or add pads in the bearing surface to adjust.<br><br>3, a number of fixed wedge bearings, in principle, allow the repair of high-speed staging and adjustment of the gap, the gap should not be properly replaced with the new tile.<br><br>4, the multi-oil wedge can be tilted shaft tile, not allowed to repair the tile block, the gap to carry out non-compliance with the timely replacement of the tile block. The thickness of the adjustable mat can be adjusted by adjusting the amount of W added to the stainless steel liner block in the rear block, thinning or adjusting the thickness of the block. Note that the thickness of the polyoilable wedge can be poured shaft tile, the thickness of the same group of tiles should be less than 0.01mm.<br><br>The main causes of bearing failure are defects and overload: When the applied load exceeds the strength limit of the material, the part is called overload break break. The main cause of overload is through a sudden failure of the host or improper installation. Microcracks, shrink holes, bubbles, bulk foreign objects, and tissue strains of bearing parts can cause severe vibration or shock of overload burns at the time of fracture defects, known as fracture defects.

Invalid adjustment mode of rolling bearing stuck<br>2020-04-24 10:35<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, forming a deep spalling.

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 can be adjusted by hand scraping or adding a pad on the surface of the bearing, if circumstances permit.<br>3.

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.

The overload is mainly caused by the sudden failure of the host or improper installation.
