Abstract
This utility model relates to a kind of magnetic lubrication sliding bearing, its principle is that the lining of sliding bearing produces magnetic field on bearing block, using magnetic fluid as lubricant medium in gap between lining and bearing block, magnetic fluid medium is uniformly attached to the outer surface of lining under the action of a magnetic field, play the effect of lubrication, the bearing capacity of this Used in Boundary Lubrication of Magnetic Fluids film is greatly enhanced, hence it is evident that reduce the abrasion between lining and bearing block.The magnetic lubrication sliding bearing that this utility model relates to, it is made up of lining (1), permanent magnet one (2), bearing block (3), bearing block liner (4), permanent magnet two (5) five part, between the gap of lining (1) and bearing block liner (4), is full of magnetic fluid medium (b).Being mainly characterized by of this method for designing, loading capacity of oil film is remarkably reinforced, and can bear high speed, high capacity, and simple in construction, easily install.
Description
Technical field
The present invention relates to Bearning mechanism, be related specifically to a kind of magnetic lubrication sliding bearing.
Background technology
Sliding bearing is the bearing worked under sliding friction.Sliding bearing stable working, reliable, noiseless.At liquid
Under lubricating condition, slidingsurface separately is not occurred directly to contact by lubricating oil, it is also possible to be greatly reduced friction loss and surface
Abrasion, oil film also has certain vibration absorption ability, but sliding bearing starting friction resistance is bigger.The lubrication principle of sliding bearing is
The formation of oil film wedge, and the bearing capacity of thin Film ratio oil film is eager to excel, wherein the bearing capacity of oil film also with the power of lubricating oil
Viscosity is directly proportional, and is also directly proportional to the relative velocity between two slidingsurfaces under most of service conditions, and transports at top load
In the case of Zhuaning, oil film thickness is the lowest, loses the ability of bearing load, and axle weares and teares with lining.Therefore sliding bearing
Application scenario is typically under the working condition of low speed, underloading or intermittent work.Present invention generally provides one can bear at a high speed,
The magnetic lubrication sliding bearing of high capacity, in the gap of two slidingsurfaces, lubricant medium is magnetic fluid, and wherein lining produces magnetic field,
Magnetic fluid medium is uniformly attached to the outer surface of lining under the action of a magnetic field, plays the effect of lubrication, this Used in Boundary Lubrication of Magnetic Fluids film
Bearing capacity be greatly improved, reduce the abrasion between lining and bearing block, and simple in construction, easy-maintaining, more safety can
Lean on.
Summary of the invention
It is an object of the present invention to provide a kind of bear at a high speed, the magnetic lubrication sliding bearing of high capacity, its operation principle is sliding
Magnetic field is produced on the lining of dynamic bearing and bearing block, using magnetic fluid as lubricant medium in the gap between lining and bearing block,
Magnetic fluid medium is uniformly attached to the outer surface of lining under the action of a magnetic field, plays the effect of lubrication, this Used in Boundary Lubrication of Magnetic Fluids film
Bearing capacity be greatly improved, reduce the abrasion between lining and bearing block.
Realize above-mentioned purpose be the technical scheme is that
The present invention relates to a kind of magnetic lubrication sliding bearing, by lining (1), permanent magnet one (2), bearing block (3), bearing block
Liner (4), permanent magnet two (5) five part form, and wherein lining (1) and bearing block liner (4) are permeability magnetic material, bearing block
(3) being non-magnet material, bearing block (3), bearing block liner (4) are interference fit, between lining (1) and bearing block liner (4) are
Gap coordinates, and is full of magnetic fluid medium (b) between the gap of lining (1) and bearing block liner (4).At bearing block (3) and bearing
Seat liner (4) is provided with lubricating cup hole (a), and magnetic fluid can be flowed between lining (1) and bearing block liner (4) by lubricating cup hole (a)
Gap.
Being mainly characterized by of this method for designing, is situated between using magnetic fluid as lubrication in the gap between lining and bearing block
Matter, magnetic fluid medium is uniformly attached to the outer surface of lining under the action of a magnetic field, plays the effect of lubrication, this Used in Boundary Lubrication of Magnetic Fluids
The bearing capacity of film is greatly improved, and reduces the abrasion between lining and bearing block, can bear at a high speed, high capacity, simple in construction,
Easy-maintaining, more safe and reliable.
The present invention tries out through user, and reaction effect is good.
Accompanying drawing explanation
Fig. 1 is the structure principle chart of the present invention a kind of magnetic lubrication sliding bearing.
In figure: wherein Fig. 1 (a) is front view, Fig. 1 (b) is left view profile, 1. lining, 2. permanent magnet one, 3. bearing
Seat, 4. bearing block liner, 5. permanent magnet two, a. lubricating cup hole, b. magnetic fluid medium.
Detailed description of the invention
Fig. 1 is the structure principle chart of the present invention a kind of magnetic lubrication sliding bearing, magnetic lubrication sliding bearing in the present embodiment, by
Lining (1), permanent magnet one (2), bearing block (3), bearing block liner (4), permanent magnet two (5) five part form, and wherein serve as a contrast
Set (1) and bearing block liner (4) are permeability magnetic material, and bearing block (3) is non-magnet material, bearing block (3), bearing block liner (4)
For interference fit, lining (1) and bearing block liner (4) are matched in clearance, in the gap of lining (1) and bearing block liner (4) it
Between be full of magnetic fluid medium (b).Being provided with lubricating cup hole (a) at bearing block (3) and bearing block liner (4), magnetic fluid can be by oil
Cup aperture (a) flows into the gap between lining (1) and bearing block liner (4).Due in the gap between lining and bearing block with magnetic
Fluid is as lubricant medium, and magnetic fluid medium is uniformly attached to the outer surface of lining under the action of a magnetic field, plays the effect of lubrication,
The bearing capacity of this Used in Boundary Lubrication of Magnetic Fluids film is greatly improved, and reduces the abrasion between lining and bearing block.
