Deep groove ball bearings in use, the failure is a common defect will seriously lead to the bearing can not be used properly or cause damage to bearings and equipment. Therefore, we found that failure of deep groove ball bearings failure, need to find the appropriate measures to solve. Bearing damage is not a single cause, in order to let you have a more specific understanding, we come to tell you the common failures of deep groove ball bearings which.
one. Contact fatigue failure
Contact fatigue failure means that the working surface of the bearing is subject to alternating stress and failure. Contact fatigue spalling occurs at the deep groove ball bearing surface, often accompanied by fatigue cracks, first from the contact surface below the maximum alternating shear stress generated, and then extended to the surface to form a different peel shape, such as point-like pitting or hemp Peeling off, peeling into small flakes, said shallow flake. Due to the gradual expansion of the peeling surface, and often extended to the deep, the formation of deep flaking. Deep flaking is the fatigue source of contact fatigue failure.
two. Wear failure
Wear failure refers to the relative sliding friction between the surface leading to the working surface of metal wear and tear caused by the failure. Continuous wear will cause the deep groove ball bearing parts gradually damaged, and ultimately lead to the loss of deep groove ball bearing dimensional accuracy and other related issues. Wear may affect the shape changes, with the gap increases and changes in the surface morphology, which may affect the lubricant or to a certain degree of pollution caused by complete loss of lubrication, so that the loss of rotation accuracy of bearings and even normal operation. Wear failure is one of the common failure modes of all kinds of bearings, which can be divided into the most common abrasive wear andadhesive wear.
Deep groove ball bearings as the main components of locomotives, especially traction motor, axlebox bearings, its function plays a decisive role in the safe transportation, locomotive running on the line, once the deep groove ball bearing failure will lead to the whole train can not run , Blocking the transport line, especially the passenger train failure, resulting in greater negative impact. Therefore, once discovered deep groove ball bearing breakdown, must carry on promptly processing, in order to avoid causes the accident.
