Judge the fault of IKO clutch bearing through contact friction state

General thin-walled bearings are used to carry axial load and radial load, and their ability to carry eccentric load is very limited. If an eccentric load is applied to these bearings, it will cause unreasonable load distribution in the bearings, which will sharply reduce the service life of IKO bearings and produce heating. Load trajectory under eccentric load.Judge the fault of IKO clutch bearing through contact friction state

• The geometric tolerance of bearing chamber is out of tolerance
• The out of tolerance of the shape and position of the bearing chamber will affect the internal load distribution of the Thin-walled bearing, resulting in abnormal load traces.
• The load trace indicates that the roundness of the bearing chamber may be out of tolerance, resulting in the ball in the non load area also bearing the load. In this way, the bearing will be heated and noisy after operation. 
• If the load track is found after removing the Thin-walled bearing, the roundness of the bearing chamber needs to be adjusted. The roundness of geometric tolerance is out of tolerance.Judge the fault of IKO clutch bearing through contact friction state
• The residual clearance of IKO bearing is too small
• Generally speaking, normal thin-walled bearings always have a certain residual clearance during operation, which will be distributed in the non load area. The curve of the influence of residual clearance on the service life of rolling bearing. When the remaining clearance is too small, the bearing will be very easy to be stuck, resulting in early failure.
•  The performance of these failed bearings before burning is noise and heating, and the load track on the surface of Thin-walled bearing raceway may cause the residual clearance of IKO bearing to be too small. 
• The factors may include: too tight fit of inner ring, too large temperature difference between inner and outer rings, etc. Adjustment and modification shall be carried out in time.Judge the fault of IKO clutch bearing through contact friction state
• The common fault of IKO bearing is the contact dry friction between bearing and journal. Serious dry friction will lead to the increase of clutch bearing temperature and lubricating oil temperature, the decrease of viscosity and bearing capacity, resulting in malignant accidents such as sticking pad and burning shaft, and even damage the equipment and threaten people. 
• Therefore, the research on real-time monitoring and fault diagnosis of IKO bearing has attracted extensive attention.
