Bicycle bearing bearing z: how to change

As shown, vibration motor stator winding wrong: check the wiring diagram, will end when heated to the correct connection connected ( Including banding, insulation and paint) ； 。 When replace the bearing shell to remove the plate can reduce the height of the jack up the car, wood dust shield sealing is poor, often shaft oil leakage, in recent years gradually convert rubber dust shield. If often remove the different diameter of inner ring, it is recommended to use adjustable induction heater, the heater ( Figure can be quickly heated inner ring, and doesn't make the shaft gets hot. Along with the increase in austenite content, hardness and contact fatigue life with increased to peak and then subsequently and reduce, but the peak value of Ar content is different, hardness peak appears in the % Ar, peak appear in % s and contact fatigue life. First because the density of ceramic rolling ball is lower than steel, more much lighter weight, so the external ring spinning the centrifugal effect can reduce %, thus greatly extend the service life. When bearing rolling body linear velocity is very high, often USES oil mist lubrication, to avoid excessive because other lubrication oil, oil of internal friction increases set-contained spherical bearing operating temperature. Must follow car manufacturing instruction, before installation should also check the status of the shaft and bearing seat, even minor wear can also lead to cooperate, that cause of bearing early failure. Bearing wear if very few, just to repair its geometric shape, but turning on a lathe, make the journal reach correct geometric shape, then the decrease of the corresponding bearing inside diameter. Silicon nitride ceramic bearings with silicon nitride full ceramic bearing ring and roller adopts silicon nitride ( SiN ceramic material, keep using polyvinyl fluoride ( PTFE） As standard, also can use the RPA - PEEK, PI, and phenolic fabric bakelite tube, etc. Metallographic specimen after mechanical grinding and polishing corrosion with % alcohol solution, with GX - olin and company Metallographic microscope to observe the microstructure of carburized layer and distribution of carbide shape, to determine whether the organization is qualified and carbide network exceeds bid. Its working principle is: electric coil in the magnetic field force and rotational, main applicable cage: stamping steel reinforced cage, The suffix E, the domestic few) 。 Bearing in the precision grinding, due to high demand for rough, work surface grinding traces can often use the naked eye to observe its surface grinding marks mainly has the following kinds.
