Description
The present invention relates to water lubrication hydrostatic support technical field for technical field.
Background technology water lubriucated bearing using specific heat is big, free of contamination nature seawater, fresh water as lubricant medium, have
Thermal deformation is small, precision is high, zero environmental, it is cheap the advantages that, in fields such as ocean engineering, underwater reconnaissance, hydroelectric generations
Larger development is obtained.Its weak point：Because the viscosity of sea water and fresh water is small, leakage is serious, bearing capacity is small, lubricity
Difference, corrosivity are strong, and the bearing capacity of water lubriucated bearing is low, the fretting wear on support pads surface is big, and the reliability of bearing is low and fortune
Row short life.
The content of the invention it is an object of the invention to provide a kind of bearing capacity of water lubriucated bearing it is high, support pads surface rub
Scouring damage is small, the axial support pads of the reliability height of bearing and the thrust bearing of service life length.
The invention mainly comprises：Bearing block, the bearing shaft shoulder, liquid return trough, hole for back flow, axial support pads, peripheral sealing liquid band, profit
Sliding pit, three-back-shaped groove, feed liquor, auxiliary support bands A, auxiliary support bands B, lubrication pit, wedge-shaped dynamic pressure groove A, wedge-shaped dynamic pressure groove B
With wedge-shaped dynamic pressure groove C.
Wherein, at the inner ring of the two horizontal circle anchor rings coordinated in bearing block and the bearing shaft shoulder, liquid return trough is enclosed provided with one,
Liquid return trough is provided with some hole for back flow.In bearing block in the upper surface of the two horizontal circle anchor rings coordinated with the bearing shaft shoulder, with returning
The adjacent position of liquid bath, be respectively equipped with corresponding to 6 fan-shaped axial support pads, the profiles of each fan-shaped axial support pads by
Peripheral sealing liquid band composition, if the upper surface for sealing liquid band outside is provided with dry lubrication pit, the lubrication of the upper surface of peripheral sealing liquid band
Pit can be cylindrical pit, hemispherical dimples, oblong pits etc., preferably cylindrical pit.Seal outside liquid band it
Between, a circumference font groove is provided with peripheral sealing liquid band adjacent, some inlet openings are provided with three-back-shaped.Three-back-shaped groove it
Between, provided with two auxiliary support bands being parallel to each other, according to the axis of two auxiliary support bands being parallel to each other and bearing block it
Between distance, from closely to remote, respectively auxiliary support bands A and auxiliary support bands B, auxiliary support bands A's and auxiliary support bands B
If upper surface is provided with dry lubrication pit, the lubrication pit in auxiliary support bands A and auxiliary support bands B upper surface can be cylinder
Pit, hemispherical dimples, oblong pits etc., preferably cylindrical pit.Between auxiliary support bands A and auxiliary support bands B,
It is dynamic that wedge-shaped dynamic pressure groove A, wedge shape are respectively equipped between auxiliary support bands A and three-back-shaped groove, between auxiliary support bands A and three-back-shaped groove
Indent B and wedge-shaped dynamic pressure groove C, wedge-shaped dynamic pressure groove A, wedge-shaped dynamic pressure groove B and wedge-shaped dynamic pressure groove C are parallel to each other.
In the use of the present invention, lubricating fluid is flowed into by inlet opening and fills up Back Word fan-shaped chamber.Because the rotation of rotary shaft is made
With lubricating fluid is just flowed into shallow cavity region by Back Word fan-shaped chamber center depth cavity region；When lubricating fluid flows to shallow cavity region by deep chamber,
Produce dynamic pressure effect, there is provided dynamic pressure bearing capacity.Because inlet opening is lasting, into Back Word fan-shaped chamber, feed flow, lubricating fluid can only be from surroundings
Sealing liquid band outflow.Because the gap of sealing liquid band and rotation between centers is very small, only 30 microns.Therefore lubricating fluid flows through envelope
During liquid band, larger liquid resistance is produced so that the static pressure rise in three-back-shaped groove and interior support region, produce larger static pressure branch
Load.Lubricating fluid produces static pressure and dynamic pressure support power when flowing through Back Word fan-shaped chamber, therefore bearing capacity and rigidity are big.Lubricate liquid stream
During through sealing liquid band, lubricating fluid is just stored in the lubrication pit of sealing liquid band；When the lubricating condition of bearing is poor, lubricating fluid just flows
Go out to lubricate pit, substantially improve the lubricating condition of bearing block, the fretting wear of bearing greatly reduces.
The present invention has the following advantages that compared with prior art：
(1) lubricating fluid is throttled in support pads by peripheral sealing liquid band, forms liquid resistance, produce hydrostatic support power；
(2) by the speed difference of wedge-shaped dynamic pressure support groove and bearing with rotating between centers so that the lubricating fluid in wedge-shaped slot
With dynamic pressure support power；
(3) lubricating fluid is stored in pit by the lubrication pit of peripheral sealing liquid band and aiding support belt surface, and " burnt
Watt " when the lubricating fluid of storage is coated in friction surface again, improve friction and wear behavior, extend the service life of bearing.
(4) do not increase other parts, the load-carrying properties of bearing are only increased by structure design, improve friction and abrasion
Can, there is the advantages that simple in construction, cost-effective.
