ReasonsandSolutionsofBearingFeverinMetalShredder

Reasons for heating of metal shredder bearings:

1. The two bearing seats are uneven or the motor rotor is not centrifugal with the mill rotor. At this time, the machine should be stopped immediately to eliminate the fault, in order to avoid early bearing damage.

2. Bearing oil breakage or oil injection too much, pipeline blockage, lubricating grease activity is not stable;

3. Blockage of oil holes, incomplete oil filling, leakage of oil pipes, insufficient oil supply pressure,

4. The lubricating oil is dirty and mixed with debris.

5. Bearings and shafts are too tight or loose. Repair the friction area and reassemble as required.

6. The choice of lubricating oil is inappropriate, and the particle size is too large or too small.

7. There is no oil heater before the beginning of winter, and the oil is too sticky.

8. In summer, oil pump lubricants fail to pass through the oil cooler, or oil cooler encounters water pipe blockage, water flow is not smooth, water cut-off and other diseases.

9. Bearing cooling water device seizures, such as blockage;

10. Excessive force of eccentric shaft is caused by too small discharge outlet (too long thrust plate);

 

Solution of Bearing Heating in Metal Tearing Machine

To do a good job of bearing maintenance of metal shredder is the premise of long-term stable operation of the whole equipment, starting from the following specific points:

 

1. The lubricating oil should be added on time and quantitatively in strict accordance with the requirements of operation instructions. Generally, lubrication accounts for 70-80% of the bearing space. Too much or too little is not conducive to the lubrication and heat transfer of bearings and the prolongation of their service life.

 

2. Lubricating oil can reduce the friction between bearings and reduce the damage caused by wear. However, when there is too much lubricating oil, not only the effect of lubrication can not be achieved, but also the oil hole will be blocked, resulting in the heating of bearings.
