The prevention and simple treatment method of heat failure of the bearing

- Dec 07, 2017 -

The service life of any bearing depends to a large extent on the maintenance and maintenance of it to receive. This is especially true in industrial applications, often with poor working conditions, heavy load, and dust and pollution are common scales. Bearing is an important part of the main industrial equipment. Bearing problems can lead to costly downtime, equipment damage and failure. In addition, large industrial bearings represent a large amount of capital investment.

In order to achieve high equipment performance and the lowest maintenance cost reliable operation, must follow the correct processing method. This includes bearing storage, clearance, cleaning, inspection and installation.

Suitable for all friction bearing design. A special anticorrosive coating bearing is available for the selection of the bearing, but most of the bearings are not made of corrosive materials. In the handling and storage of bearings, you must be careful to ensure that they do not rust or corrode. Even a damp or unprotected relationship left by a chemical glove hand or a small amount can lead to etching in a small area, which can cause fatigue of the bearing.

New and Reformed bearings have protective coating shipments, usually in a protective cover paper or other packaging, and shipped in a carton or crate. When receiving a new or reformed--A/T-bearing, it is not packaged from the package until it is ready to be installed in the application.

Do not store directly on the cement floor, where condensation water can be collected and bearings. A pallet or bearing on a store shelf, where bearings are not subjected to high humidity or sudden and dramatic temperature changes that may lead to condensation formation in the area.

Always put the oiled paper or, if not, in the roller and tapered roller bearing cup match plastic sheeting.

The design of each type of the "" "is a unique removal process. Bearing type, bearings must be removed with special care. If improperly operated, the bearings, shafts or housings may be damaged, requiring costly repairs. For smaller bearings, there is a coachman that can help with bearing removal and so on. For a tightly fitted, or pressed, or locked place in an axle, a mechanical removal of the bearing puller is not possible and the inner ring of the bearing can be heated to ease the removal. Heat lamps or other heating equipment can be used. If a torch is on, it will change the bearing steel performance and the bearing must be discarded.

Under some special operating conditions, the life of the traditional calculation is better than that of the the long bearing, especially in the case of light load. These special operating conditions are when the rolling surface (the track and the rolling element) is effectively separated by a lubricating oil film and limits the surface damage that the pollutant can cause. In fact, under ideal conditions, the so-called permanent bearing life is possible.

1, lubricating oil has impurities, too dirty, oil ring card or the wrong number. Should change oil, find out the cause of the card to repair, oil viscosity should be exchanged when the oil;

2. Bearing damage. Check the bearing of ball bearings or ball bearings for damage. Repair or replacement if damaged;

3. Lack of oil in the bearing room. Grease filled with 2/3 oil chamber or lubricant to Standard Oil surface line

4. The lubricating grease in the rolling bearing is too much, and the lubricating oil in the sliding bearings is too low or too high. Excessive grease should be removed from the rolling bearing, or the grease in the oil chamber will be filled to 2/3;

5, bearing and shaft, and the end of the cap with a loose or too tight, too tight will make the bearing deformation, too loose easy to happen "run sleeve." When the bearing and the shaft are loose, the axle neck can be painted with metal paint, and the bearing and end cover are combined to loosen the end cover tightly, and then be processed again when tight.
