Rolling bearings is normally provided by the inner ring, outer ring, rolling elements and cage components. Inner ring mounted on the shaft (is called an axial thrust bearing ring), combined with tighter; mounted on a stand or parts of the bearing hole in the outer ring, usually combined with less. Inner and outer ring raceway, when the inner and outer rings relative to rotate, scroll bars will scroll along the Raceway. Rolling is to implement the rolling elements of rolling friction, in addition to "rotation", but also around the axis of revolution. Shape of spherical, cylindrical, conical cylindrical, needle roller, drum, etc. Cage is the role of the rolling elements evenly separated. In order to meet some of the requirements, bearing without inner or outer ring, or with dust-free, seals, and other structures. Rolling elements and the inner and outer rings of material requires a high degree of hardness and contact fatigue strength, good wear resistance and toughness. General chromium alloy steel, GCr15 common materials, such as GCr15SiMn, GCr6, GCr9, hardness after heat treatment up to HRC61-65. Cage made of low carbon steel plate punching into high speed bearing used non-ferrous metals (such as copper) or plastic cages.
When the bearing temperature rises, first determine whether the malfunction, if it rises, should be dealt with as follows:
A, bearing the installation location is not correct, might cause a large ball-end and bearing inner race and outer race retaining axial forces, cause bearing overheating.
B, use bearings precision bearings provided for better choice.
C, the use of bearings in spindle not concentric bends or holes of the box causing fever resolution is fixed spindle
D, bearing belt too tight causing the heating solution is to adjust the belt tension properly.
E, fever caused by poor lubrication of the workaround is to use code designation lubrication information and properly cleaned.
F cause fever, low Assembly quality of the solution is to improve the quality of Assembly.
G, rolling bearing inner shell run around causing heating solution is to replace the wear of bearings and related parts correct balancing of the impeller diameter and checking static balance value
H, axial force too large causing heating solution is cleaning, aligning sealed mouth ring clearance requirements
I, rolling bearing damage caused by heating solution is replacing the bearing. When we use the bearings, if found it under conditions of high temperature, you get to stop operating, and then find out its causes, and provide solution for processing in accordance with the above, but may be due to heating in the bearings for different reasons, so solve in different ways, so it is to be treated on a case, the technician helps it.
Rolling bearings are widely used in mechanical support. Its function is to ensure that bearings have sufficient life conditions, to support shaft and shaft parts and relative movement such as rotate, swing from frame, rotate under friction between reducing as much as possible, to obtain higher transmission efficiency. Commonly used rolling bearings have developed national standards, it was designed by rolling friction principle, by professional factory mass production of standard parts. Just in mechanical design based on working conditions, appropriate choice of bearing type and model design of composite structures.
