IKO flange bearing wear failure and fracture failure

Refers to the relative sliding friction between the surface abrasion failure lead to constant wear and tear of the working surface of the metal and the failure. Continuous wear will cause IKO bearing parts damaged gradually, and ultimately result in the loss bearing dimensional accuracy and other related issues. Wear may affect the shape change, the increase of fit clearance and working surface morphology change, may affect the lubricant or make its pollution to a certain degree of lubrication function is lost, so that loss of bearing rotating accuracy and will not operate properly. Wear failure is one of the common failure modes of all kinds of bearings, according to the wear and tear is usually divided into one of the most common form of abrasive wear and adhesive wear. Between abrasive wear refers to the flange bearing working surface into the external hard hard foreign body or abrasive dust on the surface of the metal particles or relative movement and the contact surface caused by wear and tear, often cause furrow in IKO bearing working surface scratch. Hard particles or other foreign body may come from inside the host, or from the host system adjacent parts sent by lubricating medium bearing inside. Adhesive wear refers to the because of the friction surface microscopic bumps or foreign bodies make the friction surface is uneven, serious deterioration, the condition of lubrication for local friction heat production, easy to cause local deformation and friction surface friction welded phenomenon, serious when the surface of the metal may be the partial melting, contact surface forces from the local friction welding points on the matrix will be torn and increase the plastic deformation. This kind of adhesive - — Tear - — Adhesive cycle constitutes the adhesive wear and tear, in general, mild adhesive wear is called a scratch, serious adhesive wear called occlusion. Flange 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. IKO 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 the 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, most usually appear IKO bearing fracture failure for overload failure.
