Consumption will often meet the condition of the rolling bearing 'fever', if cause analysis is not clear, disposal measures are not timely, inappropriate and often get twice the result with half the effort, and even fight can form bearing burn, reducer gear such as malignant accidents.
Improper smooth formation of the bearing fever 1, 2, smooth bearing parts design inherent lack of smooth tubing is foreign body infarction 3, smooth oil (
Fat)
Metamorphosis or not timely refueling 4 cooler fouling infarction, smooth lines, the poor cooling effect due to improper installation provoked bearing heating 1, lack of design shrinkage provoked bearing fever 2, 3 device tilted formation bearing fever, bearing its own improper assembly provoked fever 4, coupling is bad for the also can form some rotor unbalanced rotor bearing heating or failure in the process of operation because of medium corrosion or wear and tear of solid impurities, or shaft bending, will cause uneven centripetal force, so that the bearing heating, vibration, roll the serious wear and tear, until the destruction.
This a little bit about the circulation fan is especially important for mill system.
More serious due to the impeller wear, wear after the rotor balance is poorer, blower vibration is larger, often form the early failure of the bearing.
Check change bearing such as found serious fatigue spalling, not in time of oxidation corrosion, wear pit, crack, reduced to HRC< hardness;
60, or have too much noise can't adjust, should change in time.
If check, change not in time, can form bearing appears fever, different situation such as sound, vibration, etc. So that the rotor's badly damaged, thus affecting the normal consumption.
In addition, improper bearing removal, the vibration of the equipment anchor bolt loose formation, can cause bearing raceway and rolling body, indentation, bearing inner and outer race of cracking.
Bearing in the process of operation, should stop check periodically according to the rules.
Bearing quality bad rolling bearing parts in the form of point contact and line contact, long-term work under the high alternating contact stress.
The precision of the host, secure life and great resolution level in bearing.
Either common or special bearing, bearing the host to its life, performance and firm put forward high request.
So must pay attention to in the bearing part purchase acceptance check, first of all to adopt right name brand manufacturers products, key parts to adopt imported bearings, SKF bearings, NSK bearings, FAG TIMKEN bearings at bearings.
Special design, special parts should stop for roller press and slow roller bearing.
Bearing type selection, improper selection should be pay attention to limit speed of the bearing, the bearing load ability, can't over speed, overload use.
Conclusion control operation and on-site inspection personnel on the bearing temperature rise abnormalities in the equipment should be provoked enough warning, it is the early signal of the bearing and equipment problems, if improper disposal lags behind, the way, will make the condition worsens, form a serious accident.
And equipment operation and maintenance personnel should pay attention to check the bearing temperature curve and alarm information, and separation of vibration monitoring and other wrist, especially pay attention to find the real reason, bearing a fever ability thoroughly eliminate equipment hidden dangers.
