Abstract
The present invention relates to a magnetic drainage lubricating bearing and preparation of magnetic drainage lubricating grease thereof. On the basis of not changing the existing the bearing structure, the performance of the parts of the bearing is changed. An outer ring of the bearing or a sealing cover of the bearing or an inner ring of the bearing is set as a permanent magnet, or a plurality of small magnet blocks are arranged on the outer surface of the sealing cover of the bearing; thereby, the bearing forms a closed magnetic circuit. Simultaneously, magnetic drainage lubricating grease positioned in a magnetic field is filled in an inner cavity of the bearing. The magnetic lubricating grease is filled in the bearing, the lubricating grease can be prevented from being flushed by water in the outside under the action of the magnetic force, can be reserved in the bearing and can not flow out. The magnetic drainage lubricating grease is utilized to replace the existing common lubricating oil, so that the lubrication of a rolling (sliding) bearing is ensured, and the service life of the bearing is prolonged greatly. The present invention has the advantages of low construction cost, good effect and wide practicability.
Description
Technical field
The present invention relates to the lubricated bearing of hydrophobic magnetic, be particularly useful for open-air machinery, mining machinery, main equipment, steamer, oil-well rig, and be used for open-air weaponry.
Background technique
Bearing is component the most frequently used in the machinery, and its use amount is very big, because bearing is subjected to the influence of aspects such as rotating speed, temperature and environment, lubricating grease in the bearing easily runs off under external force, thereby cause the damage of bearing, according to statistics, the consumption of national annual bearing reaches more than one hundred million covers.And the main cause of damage of bearings is to cause from lubricated disappearance, particularly in the open environment down work or with machinery that water contacts in bearing, as locomotive wheel under oil field drill, the coal mine etc.This is because lubricating grease under the washing away of water, can go bad rapidly, run off, and causes the disappearance of bearing lubrication, causes destruction.Therefore for improving the working life of bearing, study a kind of can be hydrophobic again can anti-water washing away and lubrication state can ruined bearing be not on-the-spot a great problem suddenly to be solved.
Summary of the invention
Technical problem: the purpose of this invention is to provide a kind of bearing lubricated bearing of hydrophobic magnetic in working life that improves.
Technological scheme: the bearing that hydrophobic magnetic of the present invention is lubricated, it comprises bearing outer ring, bearing inner race, the bearing seal lid that is provided with between the bearing enclose, described bearing outer ring or bearing seal lid or bearing inner race are set to permanent magnet, or on the outer surface of bearing seal lid, a plurality of small magnet pieces are set, and make the closed magnetic circuit that forms N, S extreme direction between the bearing enclose all the time, in the inner chamber of bearing, be provided with the hydrophobic magnetic lubricating grease that is in the middle of the magnetic field.
Described permanent magnet bearing seal lid is set to one-sided or is set to bilateral.
Technique effect: the bearing that hydrophobic magnetic of the present invention is lubricated, on the basis that does not change existing bearing structure, change the performance at each position of bearing, make bearing form the magnetic circuit of a closure, in bearing, fill magnetic lubricating grease, make lubricating grease under the effect of magnetic force, can resist washing away of extraneous water, be retained in the bearing and do not outflow.With the alternative existing general multiservice oil of lubricating grease hydrophobic and that have magnetic, this lubricating grease can not washed away under the action of a magnetic field in rolling with magnetic circuit or sliding bearing, thereby ensured the lubricated of rolling or sliding bearing, prolonged the working life of bearing greatly.This bearing is specially adapted under open-air machinery, the coal mine in the various device under the rugged environment such as wheel, its cost is with low cost, can produce in batches, and the hydrophobic effect of magnetic lubricating grease is good, input and effect ratio reach 1: 100, have practicability widely in this technical field.

Embodiment
Below in conjunction with accompanying drawing embodiments of the invention are further described:
The bearing that hydrophobic magnetic of the present invention is lubricated, constitute by the bearing cap 5 that is provided with between bearing outer ring 1, bearing ball or roller 2, bearing inner race 3 and the bearing enclose, the material of bearing outer ring 1 or bearing inner race 3 or bearing cap 5 is set to permanent magnet, make the closed magnetic circuit that forms N, S extreme direction between the bearing enclose all the time, hydrophobic magnetic lubricating grease 4 is set in the inner chamber of bearing, and hydrophobic magnetic lubricating grease 4 is in the middle of the magnetic field of the closed magnetic circuit of setting up on the bearing all the time.Permanent magnet bearing cap 5 can be set to one-sided as required, also can be set to bilateral.On the basis that does not change former bearing performance, can be at bearing outer installment externally-applied magnetic field, as shown in Figure 2, a plurality of small magnet pieces 6 are set on the outer surface of bearing cap 5, also can make the closed magnetic circuit that forms N, S extreme direction between the bearing enclose all the time, and the hydrophobic magnetic lubricating grease 4 that is filled in the bearing is in the middle of the magnetic field all the time.
