The repeated use of the bearing
Judgment standard and the important degree, mechanical properties and control depends on the cycle, such as the following injury, they seem to have no need to use bearing replacement.
A) bearing spare parts damage defects.
B) the lawn surface rolling surface stripping agent.
They will check the bearing withdraw seems to use this attitude to see photos. In addition, to confirm the amount of residual lubricant and lubricant samples and then clean the bearing.
Instead, coarse and carefully cleaning points clear, you can use these to put metal frame at the bottom of the container.
B, rough washing, cleaning and lubricating oil or cyst in adhesion. At this point, if the oil in the SKF Bearings China rotation, attention to foreign object damage and surface rolling.
C, slowly rotating in sperm washing oil bearing, need to carefully.
Usually use neutral detergent or solvent anhydrous diesel, with warm sometimes lye so when necessary. No matter what, always filter cleaner clean. Immediately after cleaning, but appears to be coated or bearing the rust-proof antirust oil.
They need a good service and care appears to be bearing, in order to prolong its service life.
1, choice of shaft and bearing housing and bearing tolerance control: they should turn the pressure into the bearing, no soft braking feeling. Obviously not, flexible rotation, display size tolerance is too big. Rear axle pressure into the shaft rotation arm clearly "sasha vujacic" feeling, perhaps shaft tolerance is too big or shaft roundness. So good control shaft and the bearing chamber of tolerance and in order to control the plump, the domestic many manufacturers don't allow only control roundness control.
2, bearing assembly method: because the bearing is high precision products improper assembly is easy to damage the bearing damage should be installed bearing bearing channels. Special mould, can't play, when the axial compression force, only a small circle pressure circle, only more power. Need to use the pressure or hydraulic assembly time pressure and external mold in the state of level, lead to decline of dynamic damage bearing series, will take the initiative to call bearing.
3, build to prevent foreign body: rotor bearing on the clothing of dynamic balance, dynamic balance, prone to waste, so it's best to do dynamic balance within the bearing load bearing before. There are some components to build the enterprise internal bearing tu grease lubrication condition, but it is often difficult to control the effect will be better, if the operator number within the bearing oil or fat storing up large bearing axial rotation, easy in the bearings. Bearing chamber is best not to paint or fat, if you don't control bearing no leave work in it.
4, prevention: paint with rust rust sealed type unit installed in the car, the sound is very good, but in the warehouse out after some time, the machine became a big, make a phone call to cancel bearing rust phenomenon is serious. Many companies will think after bearing before, we have always advocated, motor factory now have realized the problem of the mainstream. This problem is mainly due to paint volatiles from acid determination of temperature, humidity, the formation of corrosive substances, pickling after bearing damaged bearing channel. This problem is only selected film dry in ventilation after a period of time after assembly.
