Abstract
The utility model relates to a water repellent magnetic lubricant bearing. Changing performance of every part of the bearing on the basis of not change existing foundation of bearing structure, to set up the bearing outer ring or bearing sealing cover or bearing inner ring as permanent magnet, or set up a plenty of small magnetic pieces on external surface of bearing sealing cover to make bearing as magnetic circuit, meanwhile arrange the water repellent magnetic lubricant grease in bearing inner cavity with magnetic field. Filling magnetic lubricant grease in bearing and make the lubricant grease resist the environmental water washing in the action of magnetic field force and keep the lubricant grease in the bearing. The substitute for existing common lubrication oil with water repellent magnetic lubricant grease can guarantee lubrication of rolling (or sliding) bearing, which has the advantages of prolonging greatly the service life of bearing, the cost of construction being lower with best effect and comprehensive practicability.
Description
Technical field
The utility model relates to the lubricated bearing of hydrophobic magnetic, is particularly useful for open-air machinery, mining machinery, main equipment, steamer, oil-well rig.
Background technique
Bearing is component the most frequently used in the machinery, its use amount is very big, because bearing is subjected to the influence of every 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 utility model provides a kind of bearing lubricated bearing of hydrophobic magnetic in working life that improves.
Technological scheme: the bearing that the utility model hydrophobic magnetic 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 can be set to one-sided, also can be set to bilateral.
Technique effect: the bearing that the utility model hydrophobic magnetic is lubricated, prepare hydrophobic and lubricating grease that have magnetic, 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 having the rolling of magnetic circuit (or slip) bearing, thereby ensured the lubricated of rolling (or slip) 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 embodiment of the present utility model is further described:
The bearing that the utility model hydrophobic magnetic is lubricated, holding the bearing cap 5 that is provided with between inner ring 3 and the bearing enclose by bearing outer ring 1, bearing ball or roller 2, axis of a cylinder constitutes, 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, is in the middle of the magnetic field all the time in the closed magnetic circuit that hydrophobic magnetic lubricating grease 4 is set up on bearing.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.
Claims (2)
1. the lubricated bearing of a hydrophobic magnetic, it comprises bearing outer ring (1), bearing inner race (3), the bearing cap that is provided with between the bearing enclose (5), it is characterized in that: described bearing outer ring (1) or bearing seal lid (5) or bearing inner race (3) are set to permanent magnet, or magnet piece (6) is set on the outer surface of bearing cap (5), 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 (4) that is in the middle of the magnetic field.
2. the bearing that a kind of hydrophobic magnetic according to claim 1 is lubricated, it is characterized in that: described permanent magnet bearing cap (2) can be set to one-sided, also can be set to bilateral.
