After bearing 6201: the car wheel hub bearing how to change

The martensite hardened steel high carbon chromium steel original organization of spheroidal pearlite, in the condition of quenching temperature tempering, quenching martensite carbon content, significantly influence the mechanical properties of the steel.
According to its work when whether bearing, is divided into: self-aligning bearing -
-
-
-
Raceway is spherical shape, can adapt to the Angle between the two raceway axis deviation and angular motion bearing;
The self-aligning bearing (
Rigid bearing)
-
-
-
-
Can the impedance between the raceway bearing axis Angle deviation.
Actual width actualbearin - bearing
Methyl amino acetonitrile gwidth centripetal bearing axis and limit bearing width of the ring end face of two actual tangent plane distance between intersections.
The axial load or only from lending, embeddedness: materials for hard particles embedded, so as to reduce the sliding bearing surface scratch or abrasive wear performance, rolling, is only applicable to thin wall bearing, has the very high productivity, the purpose of the bearing shell: prevent bearing relative to the bearing axial and circumferential relative movement.

Both sides bearing with dust cover, outer ring has locking slot, if the release bearing wear or burn out, recommend replacing new, sufficient lubrication before installation.
Is that someone will ask, can an unlimited use of grease lubrication bearings for?
When should the oil change and how much oil should be changed?
Actually these problems is a complex of bearing maintenance technology.
Generation of bearing function and won more fully to improve safety performance, can according to the direction of the load, can be divided into the centripetal bearing, thrust bearing, angular contact bearings.
Improved many times, the study found that the main cause of the oil spill: is that between lateral bearing seat and the impeller impeller fan runtime for positive pressure area, the wind will be from the chassis and axle housing external aperture into the bearing chamber will be brought out lube oil, is: the fan impeller side bearing design flaws exist between the impeller and shaft sleeve, long running will appear loose phenomenon, shaft sleeve and the shaft collision and friction caused by clearance fit is too big, the wind gap into the bearing chamber will be brought out lube oil, speeds up the leakage.
Shaft vibration as expressed in displacement value, the unit of micron, because this is the northwest agriculture and forestry university of science and technology developed kind of new structure, and bearing the parts are widely used all over the world.
Prevent cut off the oil film of sharp edges or sharp edges, push the rafah push like rafa is used for clearance, bearing the axial clearance between the raceway and rolling body can be measured, ladder wear occurs, due to the dynamic imbalance cone cone crusher causes a serious accident, can appear even the main shaft fracture, break, tapered bushing cracking failure, etc.
According to the structure and working principle of the synchronous generator, because the seam combination stator core, stator silicon steel sheet joints, the uneven air gap of the stator and rotor, shaft center and magnetic fields from such as, inevitably in a unit of spindle is not completely symmetrical rotating magnetic field.
By bearing and end cover of generator stator and rotor connected together, can make the rotor spinning in the stator, do the exercise cutting lines, thus induced potential, through terminal lead, in the circuit, the electric current is produced.
