Fracture and fracture failure refers to the parts completely lost in a work or can not meet the expected function called fracture failure. Failure is the most important and most dangerous machinery products failure, its classification is more complex. Imported bearing also can appear as an important part of mechanical failure, the following simple for everyone to introduce why imported bearings will appear fracture failure
A, improper installation
When bearing in the customer's hands, the bearings' quality and guaranteed under the premise of bearing handling process, then the factors affecting bearing use the existence of defects is to install.
Install the reason is various defects. One is for SKF bearing of precision bearings and use of lubricating oil, before installation without cleaning, so in the presence of foreign bodies in the bearing internal when installation; The second is for bearing installation environment, cleanliness is not high, can make the dust intrusion bearing; Three is to bearing, by adopting the method of interference fit interference quantity selection of improper installation, improper; Four is installed without timely inspections bearing.
Second, the fatigue
Below the surface of bearing fatigue load is caused by shear stress of periodic appear phenomenon. For bearing fatigue, it is the main form of expression of bearing metal surface spalling, the peeling situation serious bearing use increases with time. When reach to a certain extent, makes the bearing noise or vibration condition, known as the fracture failure.
Third, poor lubrication
According to a large amount of data, the import of bearing failure in many cases are caused by improper lubrication. Improper lubrication, one kind is due to failure of lubricant type selection, due to different bearing type, type, the lubricant is also different. Another is caused by improper use the amount of lubricant. They will have an impact on the emergence of the bearing vibration condition, resulting in bearing faults.
Fourth, overloaded
Excessive load, high impact will affect bearing fracture, only can withstand the load within the scope of work as much as possible to avoid the emergence of the phenomenon.
