Inspection Of Thrust Bearing After Installation
Aug 21, 2018

When the thrust bearing is installed, the vertical degree of shaft and center line should be checked. Diesel copper sleeve Method is to fix the dial gauge box shell end face, make the table touch the top of the head of the ring raceway on bearing axle bearing, and observe the dial gauge pointer, if the pointer deflection, axial circle and not vertical shaft centerline. When the case hole is deep, it can also be tested with the extended micrometer head.

 

When the thrust bearing is installed correctly, its Powder metallurgical bearing seat can automatically adjust to the rolling of the rolling body, making sure that the rolling body is in the upper and lower circle. If the reverse, not only the bearing work not normal, and the coordination surface JTW self-lubricating gasket will be severely worn. Because the shaft circle and the seat ring and the difference is not obvious, the assembly should be extra careful, do not mistake. In addition, the seat of the thrust bearing and the bearing holes should also be left between 0.2 0.5 mm clearance, to compensate parts processing, installation error caused by inaccurate, when the bearing ring during operation center offset, the clearance can be adjusted to ensure the automatic, the avoidance of friction, make its normal operation. Otherwise, the bearing will be badly damaged.

Advantages of all-steel bearing

 

1. Durable wear and wear - the fatigue life of the ceramic bearing can be 10 to 50 times longer than that of the whole steel bearing, and the Bimetal sleeve life of the ceramic bearing is about 3 to 5 times higher than that of the all-steel bearing.

2. High speed and acceleration - can operate under the conditions of the dn value of over 3 million JFB flips the edge bushing, which can be reduced by sliding, wearing and heating;

3. Resistance to abrasion - because the ceramic material FB090 bronze rolling bearing is inert material, it is more resistant to corrosion and wear;

4, the lubrication rarely - low friction coefficient of ceramic material, ceramic bearing is lubricated by oil, in lube oil is thinning or boundary conditions, its lubricating ability is still not less than the traditional steel bearings commonly used lubricants;

5. High temperature resistance - full ceramic bearing can be in 500. C above temperature work;

6. The rigidity is large, because the elastic modulus of ceramic material is high, and its rigidity is 15-20% larger than ordinary steel bearing.

7. Low torque -- according to the structure, the torque of ceramic bearings is reduced by a third;

8. Non-magnetic non-conductive - ceramic bearings are not subject to magnetic or electrical damage.
