1.Slewing Ring Bearing Abnormal Noise

For large slewing ring bearings, especially during the installation and operation of newly installed large slewing ring bearings, the sound, abnormal sound, regular, segmented and unknown situations, after eliminating the interference of foreign objects, can be adjusted from the following aspects. In most cases , can be excluded, Luoyang Bearing Yuan Gaogong, 158-9658-0190. Please do not reprint.

Increase the lubricating strength and lubricating interval, all the lubricating holes are fully lubricated, and the test run is about a week. If the effect is not obvious, adjust it from the following aspects:

1. First loosen all the mounting bolts of the slewing ring bearing outer ring;

Next, measure the clearance between the flange and the slewing ring bearing contact surface:

For gaps greater than 0.1, it is recommended to use copper or stainless steel pads to eliminate them;

Then re-tighten all the bolts with the symmetrical cross method;

Finally, try turning it on again:

Turn forward and reverse for three turns each and then listen to the original abnormal noise?

2. If there is still the original abnormal sound after the first step, loosen all the inner ring bolts, and repeat the operation according to the first step.

Note:

The outer ring first, then the inner ring, the order cannot be reversed.

3. Measure the backlash of the large and small gears:

First find the green paint on the outer tooth top of the slewing ring bearing, and measure the backlash value of the big and small gears based on the tooth with the green tooth top;

suggestion:

Controlled by industry experience in:

0.6~0.8mm is better. Modulus 0.03/0.04*Modulus m

4. The method of adding grease:

4.1, it is recommended to close the middle and lower drain oil circuits;

4.2, only add grease to the top row of oil holes;

4.3. Use grease with higher viscosity for filling;

4.4, add grease quantity:

Until a small amount of grease overflows from the top sealing ring.

2.Slewing ring bearing and pinion meshing

Classification of molybdenum disulfide extreme pressure grease:

Lithium molybdenum disulfide grease is a high temperature grease that can adapt to ordinary loads”);”>conditions

Molybdenum disulfide extreme pressure lithium grease is a high temperature grease under high load “);”> conditions

Molybdenum disulfide extreme pressure lithium complex grease is a high load high temperature grease with synthetic base oil

1. Molybdenum disulfide has good water resistance, good mechanical stability and pressure resistance, and is mainly used for the lubrication of heavy-duty machinery.

2. Molybdenum disulfide has a certain corrosive effect on copper and its alloys. It is not suitable for copper pipes to be transported, which will cause pipeline blockages and cause oil shortage accidents.

3. It is not suitable for worm gear and worm gear made of copper alloy, which will lead to broken teeth due to corrosion.

4. It is not suitable for rolling bearings with copper alloy cages, which will cause the cage to break due to corrosion.

5. When parts made of copper and its alloys need to be lubricated, it is best not to use lubricating products containing molybdenum disulfide.
