The use of IKO joint bearing damage analysis of life cycle

Joint bearing damage after removing inspection, subject to the damage condition of bearing discriminant IKO bearing fault and damage. 1. Flake metal rolling element bearing raceway appearance and inner and outer ring raceway surface are accepted the role of the periodic pulse load, resulting in a periodic change of contact stress. When stress cycles to reach a certain value, the rolling element bearings, their work within or surface will produce fatigue spalling. If IKO bearing load is too big, can make this kind of tired. In addition, the bearing assembly is not straight, shaft bending, also can produce roll flaking off. Bearing raceway fatigue spalling can reduce the running accuracy of shaft vibration and noise agencies attacks. 2. 。 Bearing burn burn bearing the heat tint of raceway and rolling body. Burns the cause of the lack of common is smooth, smooth oil quality will not fit the request or metamorphosis, and bearing assembly too tight. 3. Plastic deformation of bearing raceway and roller contact surface appear uneven pits, clarify bearing produce plastic deformation. Its reason is bearing in large under static load or shock loading, beyond the appearance of part stress data of yield limit, this situation general attack on the low-speed rotation of the bearing. 4. Bearing race crack crack reasons at the bearing race may be bearing fit tight, loose bearing outer ring and inner ring, hold a distortion of bearing, gear bearing appearance processing etc. 5. Stick to fracture at the reason is the lack of smooth, rolling body and broken, a circle tilt, etc. 6. Insist on frame metal adhesion on the rolling body possible reason is stuck inside a stick to frame or roller smooth lack. 7. Seat ring raceway serious wear and tear may be fall into the object in seat, smooth oil deficiency or smooth oil brand not appropriate. The main elements affecting the joint bearing damage is: load condition, smooth, assembly conditions, environmental conditions and material or manufacturing precision, etc. In the joint bearing device, if not serious stop alignment, alignment can cause bearing under other loads, friction, and vibration. These could accelerate fatigue and reduce the use of the bearing life, and it might damage the other machine parts the use of the term. In addition, the increase of vibration and friction could significantly increase the risk of energy cost and premature failure. During the period of using, often of joint bearing stop monitoring operation of external conditions, such as temperature, vibration and noise measurement, etc. These regular check will help identify potential problems and will avoid unexpected machine to suspend the phenomenon, make the spending plan, to be completed, the progress of the factory spending power and efficiency. In the process of operation, bearing request has the correct smooth again, its performance. Bearing smooth way, divided into oil and grease smooth smooth. In order to make the bearing function well, first of all, to choose appropriate use condition, the purpose of smooth solution. If only consider smooth, oil slick smoothness is preferred. But there are fat smooth can simplify bearing structure around the expertise. When bearing will reach its final use period of time, should be traded off. Is bearing can not be used, but properly unloaded the original bearings, timely exchange of new joint bearing, for the new bearing use can play a good role in promoting the extension of life span. First of all, the usefulness of the appropriate way to unload tools will help prevent damage on other machine components, second, incorrect unload technology can be a hazard to the operator.
