Based on the FAG bearings FAG bearings developed, its working principle is based on rolling friction instead of sliding friction, generally consists of two rings, consisting of a group of rolling elements and cage's versatility is very strong, a high level of standardization and serialization of machine components. Different working conditions due to various mechanical, for bearings in terms of carrying capacity, structure and performance have raised a variety of different requirements. To this end, the bearing required a wide range of structures. However, the most basic structure consists of the inner ring, outer ring, consisting of rolling elements and cage.
1. contact fatigue (fatigue wear) failure
Contact fatigue failure is one of the most common failure mode for various kinds of FAG bearings, bearing surface results from repeated the role of contact stress of circular failure. FAG bearing surface contact fatigue spalling is a process of fatigue crack initiation and extension to crack. Initial contact fatigue crack first produced from the contact surfaces of the following maximum orthogonal shear stress, and then extended to surface pitting or tiles or small flaking, peeling or pitting corrosion is called point of the former; the latter is referred to as shallow layer peeling. Initial crack in the cardiac area at the junction of the Department and the hardened layer produced, resulting in early hardening layer peeling off, it is called a hardened layer peeling off.
2. the failure of adhesion and abrasive wear
All types of bearing surface of one of the most common failure modes. FAG bearings relative sliding friction between the parts leading to their surface metal loss referred to as sliding friction losses. Size and shape wear will make parts of sustainable change, FAG bearing clearance increases work surface deterioration, thus losing running accuracy, bearing does not work properly. Sliding wear forms can be divided into abrasive wear, corrosion, wear and tear, abrasion, adhesion of fretting wear and so on, one of the most common abrasive wear and adhesive wear.
FAG bearings friction between the surfaces of the part caused by external hard particles or metal grinding phenomena belonging to abrasive wear of friction and wear.
For bearings, the inner ring is often the shaft tight fit, and operate with the axis, usually associated with the outer ring or mechanical bearing shell hole transition fit, played a supporting role. However, on some occasions, also operate in the outer ring, inner ring fixed play a supporting role or inner ring, outer ring while running. FAG bearings, and tight fit together campaign that axis, or mechaical bearing shell hole transition fit plays a supporting role that seat. Rolling (rolled steel ball, roller or needle) are typically in bearings with cage between evenly arranged in two rings for rolling movement, its shape, size and number of direct impact of FAG bearings load carrying capacity and performance. Cage except for rolling elements can be separated evenly, effects of rotation and also can boot improved internal lubrication of the bearing performance and so on.
