Koyo stainless steel bearing failure of emergency treatment

Koyo bearing failure of the main reason is that defects and overload two factors. When the loads more than material strength limit fracture caused by parts called overload fracture. Overload reason mainly is the main engine failure or improper installation. Stainless steel bearing parts of micro crack, shrinkage cavity, bubbles and large foreign impurities, overheating organizations and local burns and other defects during the impact overload or violent vibration will cause fracture in defect, known as defect fracture. It should be pointed out that koyo bearing in the process of manufacturing, for raw materials into the factory reinspection, forging and heat treatment quality control, process control through instrument analysis of the existence of the above defects and correct still must strengthen control in the future. But in general, usually bearing fracture failure of most for overload failure. Koyo bearing, the main task of the failure analysis is based on a lot of background material, analysis data and failure forms, find out the main factors of stainless steel bearing failure, so that the improvement measures are put forward, extension of koyo bearing, avoid premature failure of the bearing of the sudden. Koyo bearing in the process of running, sometimes into foreign stainless steel bearing surface between hard particles or hard foreign body or abrasive dust on the surface of the metal, it can cause furrow is bearing abrasion, inside these hard foreign body through into the stainless steel bearing lubrication medium, with the continuous operation of koyo bearing, local friction heat production, easy to cause the friction surface phenomena, local micro welding deformation and friction of partial melting may even happen, finally cause occlusion phenomenon. Koyo bearing fracture have defects and overload causes two factors, when the loads more than material strength limit fracture caused by parts called overload fracture of overheating in stainless steel bearing can also occur during the operation of organizations and local burns and other defects, defect caused by fracture. Generally we can through the instrument to monitor belong to which kinds of fracture, in most cases, the stainless steel bearing fracture failure mostly caused by overload.
