1: bearing support seal:
bearing support sealing means bearing external, such as bearing shell parts, shaft parts, and cover part of the additional sealing devices.
Bearing seals in the choice of bearings should be considered when the bearing lubricant type (fat or oil), sealing contact with the surface of the circular speed, bearing misalignment, and many other factors. Do not ask for the seal, bearing relatively high speed shaft installation error when it is too large, choose non-contact seal. Non-contact seals can be divided into space and the use of centrifugal force, using two kinds of seals. To enhance the sealing effect, you can attach non-contact centrifugal film or tape delay, using centrifugal force to control the emission of grease to achieve the sealing effect. If the working environment,
Have the possibility of water infiltration or bearing oil lubrication, the bearing contact area can be used seal. Contact seals are generally oil seal, grease seals, mechanical seals.
2: bearing everyday use common sense:
bearings for Attention are as follows:
1, Careful use.
Bearing in use to give a strong impact, will have scars and indentations, a cause of the accident. Severe cases, cracks, fracture, it should be noted.
2, To maintain bearing and the surrounding clean.
Even the eyes can not see the small dust, will bring bad effect to the bearings. So, to keep the surrounding clean, so dust will not invade bearings.
3, Bearing in mind the rust.
Bearing operation, the hand will be rusty because Khan. Note operation with clean hands, the best possible wear gloves.
4., Using the appropriate operational tools.
To replace existing tools to prevent, you must use the appropriate tool.
For as long as possible in order to maintain good condition bearing the original performance, to maintenance, overhaul, in order to prevent accidents in the first place, to ensure reliability of operation, increase productivity, economy. The corresponding operating conditions of mechanical maintenance best operating standards, on a regular basis. Including monitoring running status, to supplement or replace the lubricant, the demolition of the checks on a regular basis. As the operation of the maintenance issues have bearing rotating sound, vibration, temperature, lubricant condition and so on.
