Thrust ball bearings common faults and necessary remedial measures

Bearings and shaft diameter or bearing bore interference small, multi-use push method assembly. The easiest way is to use copper and hand hammer, according to a certain order to beat self aligning bearing with symmetrical interference fit of the seat, the thrust ball bearings successfully pushed. Alternatively, use a soft metal hammer into the casing by hand or push press. If improper operation, will make the seat deformation cracking, or hammering at the hands of non-interference fit on the seat, then make the body produce bearing raceways and indentation or indirect bearing is damaged.
Bearing in the assembly, if interference with the shaft diameter is large, the general assembly of thermal loading method. Upcoming needle roller bearings into drums filled with oil, the oil drums external heating with hot water or flame, the process requires heating the oil temperature control at 80 ℃ ~ 90 ℃, generally not more than 100 ℃, up to no more than 120 ℃. Quickly removed after the suit in the journal bearing heating. If the temperature control to improper heating temperature is too high, then make the bearings caused tempering hardness decreased, thrust ball bearings running on easy to wear, peeling, or even cracking.
Stripped
Injury Status: under load bearing and then rotate the inner ring, outer ring raceway or rolling a decent showing scaly due to rolling fatigue peeling phenomenon.
Cause: The load is too large. Install bad (non-linearity) torque loads foreign invasion, water. Poor lubrication, improper lubricant thrust ball bearing clearance inappropriate. Bearing box accuracy is not good, the deflection of the bearing box uneven shaft rigidity large rust, caused by the development of erosion points, scratches and indentations (surface deformation phenomena).
Measures: The size and re-use of the Institute to improve the load agricultural bearings checking installation methods to improve the sealing device shutdown rust. Using the appropriate viscosity lubricant to improve lubrication method. Check the shaft and precision bearing housing. Check the clearance.
Peeling.
