TIMKEN bearings after installation, in order to check whether installed correctly, check for running.
Small mechanical can rotate with the hand, to confirm whether to rotate smoothly.
Check project has caused by foreign bodies, scars, creasing seized up, due to bad installation, installation of seat processing bad moment is not stable, because the clearance is too small, installation error, seal friction caused by the torque is too big, and so on.
If there is no abnormal can start power operation.
Large machinery from manual rotation, so after no-load start immediately cut off the power, machine idle, check whether there is presence of vibration, noise, rotating parts contact, etc. , confirmed after no abnormalities, into power operation.
Dynamic operation, from the beginning of the no-load speed, slowly up to the rated operating conditions.
Test run to check the items, whether there is abnormal sound, plane bearing temperature, lubricant leakage or discoloration, and so on.
If discovery is unusual, should immediately stop, check machine, when it is necessary to remove the bearing inspection.
Temperature, average according to the external temperature of the bearing.
But using the oil hole directly measuring the temperature of the TIMKEN bearing outer ring more accurate.
The bearing temperature, starting operation gradually increases, usually 1 ~ 2 hours after the temperature stability.
If the bearing installation, the temperature will rise sharply, abnormal high temperature.
The reason such as lubricant, bearing clearance is too small, too much bad installation, excessive friction sealing device, etc.
High-speed rotating occasions, such as the choice of structure, the lubrication method error is also the reason.
1, keep the bearing and the surrounding clean.
Even the eyes can't see the little dust, also can bring bad influence to TIMKEN bearings.
So to keep the surrounding clean the dust from invading plane bearing.
2, carefully use bearing in use for TIMKEN bearing strong impact, will produce scar and creasing, become the cause of the accident.
Severe cases, can crack, fracture, so must pay attention to.
3, use the appropriate tools to avoid operation with existing tools to replace, must use the appropriate tools.
4, to pay attention to the corrosion of surface bearing bearing operation, sweat will become the cause of rust.
Pay attention to the operation with clean hands, it is better to try to bring gloves.
Understand the using method of TIMKEN bearings will have twice the result with half the effort, it is very important.
When near bearing mechanical parts have been used for oil lubrication or need to rely on lubricating oil cooling, bearing lubrication should be adopted.
In bearing heavy load and high speed, or with external heat comes in, there may be a cooling requirements.
Trace the lubrication method is used, such as oil drip lubrication, oil mist lubrication oil and lubrication, can keep stirring oil loss and bearing friction are quite small.
When using do air carrier, could directly and make the air helps to seal oil.
Plane bearing high rotational speed and need good cooling jiao fruit, a large number of lubricating oil can be directly spray to all of the contact surface.
