Original Fag Spherical Roller Bearings [url removed, login to view] sold by FANADE Industry(HongKong) Ltd has won the majority of their customer support and trust with the reasonable prices,convenient logistic system,excellent service,and strong technical force,which is a win-win situation between the company and its [url removed, login to view] the goal of meeting Customers' demand is our pursuit,FANADE has gained abundant strengths in supply of tapered roller bearings,cylindrical roller bearings,thrust ball bearing,Inch series bearings,spherical bearings,ball bearings and various non-standard bearings with imported and domestic famous brands including Swedish SKF bearings,German FAG,INA bearings,Japanese NSK bearings,Japanese NTN bearings,Japanese KOYO,FYH bearings,Japanese IKO bearings,American TIMKEN bearings,Britain RHP and other famous imported [url removed, login to view] we'd like to talk about The main performance of the composite bearing failure in use.
The main performance of the composite bearing in using failure has the following aspects.
(1) the surface fatigue damage this form of damage in a small amount of material from a roll or roller surface spalling. Peeling is a time critical cyclic load and stability caused by the stress on cracking phenomenon, is mainly due to the presence of foreign particles in the hertzian contact area, through the ring between the roller and rolling countless times, can produce stress concentration in the pressure on the surface elliptical area, usually its position at the maximum orthogonal shearing stress, the stress concentration as a continuation of the time, under alternating stress is gradually expanding, can form cracks, eventually lead to some material from the surface spalling. Surface fatigue spalling is mainly due to the impurities exist in the lubricant contact surface defects such as scratches, pitting, cause local stress concentration, caused the development of surface fatigue spalling caused by surface [url removed, login to view] main performance of the composite bearing failure in use.
(2) internal spalling are the typical features of this form flake
Beneath the surface to form larger crack, the crack before appear spalling, the load stress peak position parallel to the surface into extension. If under the surface of the crack expand to the surface, or from the surface cracks at the start of the near surface has changed the organization of regional distance for a commonly will flake. Induced spalling under the raceway surface made of nonmetal inclusions and bond strength of steel matrix and materials caused by the plastic deformation.
(3) INA bearing parts damaged bearing parts damage phenomenon, mainly occurs in the case of bad working condition of bearing, The main performance of the composite bearing failure in [url removed, login to view] as rolling force, rolling speed is high, the poor lubrication condition, combination bearings, such as a fever. In the present optimization design, the service life of bearing is reflected in the bearing of the whole life. Bearing damage to any parts will lead to the termination of the service life of the whole bearing. Such as maintain the strength of the frame optimization design, the pillar type cage a pillar of strength, pillar and cage welding performance and rolling body contact with the guard in the form of optimized design, etc.
Bearing is fixed in mechanical parts, is the main part of the machinery, its role is basically used to keep the shaft center position, and to control the movement of the parts. Composite bearing has a vital role in any machine, if have no bearing, machine can't [url removed, login to view] main performance of the composite bearing failure in use.
Many users are reflected in the use of INA bearings, the faults of bearing heating is the most common, the failure can also affect the composite bearing's life and property. So, this fault is formed? Below, it is stated the knowledge for everyone.
