Description
Technical field the present invention relates to water lubrication hydrostatic support technical field.
Background technique water lubriucated bearing adopts large, the free of contamination nature seawater of specific heat, fresh water as lubricant medium, have that thermal distortion is little, precision is high, zero environmental, the advantage such as cheap, obtain larger development in fields such as ocean engineering, underwater reconnaissance, hydroelectric powers.Its deficiency: because the viscosity of sea water and fresh water is little, it is serious to leak, bearing capacity is little, poor lubricity, corrosivity strong, the fretting wear that the bearing capacity of water lubriucated bearing is low, support pads is surperficial is large, and the reliability of bearing is low and service life is short.
The fretting wear that bearing capacity is high, support pads is surperficial that summary of the invention the object of this invention is to provide a kind of water lubriucated bearing is little, the axially mounting pad of the thrust-bearing that the reliability of bearing is high and service life is long.
The present invention mainly comprises: bearing support, the bearing shaft shoulder, liquid return trough, hole for back flow, axially mounting pad, peripheral sealing liquid band, lubrication pit, three-back-shaped groove, feed liquor, auxiliary support bands A, auxiliary support bands B, lubrication pit, wedge shape dynamic pressure groove A, wedge shape dynamic pressure groove B and wedge shape dynamic pressure groove C.
Wherein, at the inner ring place of two horizontal circle anchor rings that bearing support coordinates with the bearing shaft shoulder, be provided with a circle liquid return trough, liquid return trough is provided with some hole for back flow.At the upper surface of bearing support at two the horizontal circle anchor rings coordinated with the bearing shaft shoulder, the position adjacent with liquid return trough, be respectively equipped with corresponding 6 fan-shaped axially mounting pads, the profile of each fan-shaped axially mounting pad forms by peripheral sealing liquid band, the upper surface sealing liquid band is outside provided with some lubrication pits, the lubrication pit of the upper surface of peripheral sealing liquid band can be cylindrical pit, hemispherical dimples, oblong pits etc., is preferably cylindrical pit.Seal between liquid band outside, be provided with one week three-back-shaped groove with peripheral sealing liquid band adjacent, on three-back-shaped, be provided with some inlet openings.Between three-back-shaped groove, be provided with two auxiliary support bands be parallel to each other, distance between the auxiliary support bands be parallel to each other according to two and the axis of bearing support, from closely to far, be respectively auxiliary support bands A and auxiliary support bands B, be provided with some lubrication pits at the upper surface of auxiliary support bands A and auxiliary support bands B, can be cylindrical pit, hemispherical dimples, oblong pits etc. at the lubrication pit of the upper surface of auxiliary support bands A and auxiliary support bands B, be preferably cylindrical pit.Be respectively equipped with wedge shape dynamic pressure groove A, wedge shape dynamic pressure groove B and wedge shape dynamic pressure groove C between auxiliary support bands A and auxiliary support bands B, between auxiliary support bands A and three-back-shaped groove, between auxiliary support bands A and three-back-shaped groove, wedge shape dynamic pressure groove A, wedge shape dynamic pressure groove B and wedge shape dynamic pressure groove C are parallel to each other.
In use, Lubricants is flowed into by inlet opening and fills up the fan-shaped chamber of Back Word in the present invention.Due to the rotary action of rotatingshaft, Lubricants just flow into shallow cavity region by the dark cavity region in center, Back Word fan-shaped chamber; When Lubricants flows to shallow cavity region by dark chamber, produce dynamic pressure effect, dynamic pressure bearing capacity is provided.Because inlet opening continues feed flow in the fan-shaped chamber of Back Word, Lubricants can only flow out from the sealing liquid band of surrounding.Because the gap between sealing liquid band and rotatingshaft is very little, only there are 30 microns.Therefore, when Lubricants flows through sealing liquid band, produce larger liquid resistance, the static pressure in three-back-shaped groove and interior support region is raised, produces larger hydrostatic support power.Lubricants produces static pressure and dynamic pressure support power when flowing through the fan-shaped chamber of Back Word, therefore bearing capacity and rigidity large.When Lubricants flows through sealing liquid band, Lubricants is just stored in the lubrication pit of sealing liquid band; When the lubricating condition of bearing is poor, Lubricants just flows out lubrication pit, greatly improves the lubricating condition of bearing support, and the fretting wear of bearing reduces greatly.
The present invention compared with prior art tool has the following advantages:
(1) rely on peripheral sealing liquid band by Lubricants throttling in support pads, form liquid resistance, produce hydrostatic support power;
(2) rely on wedge shape dynamic pressure support groove and the speed difference between bearing and rotatingshaft, make the Lubricants in wedge slot have dynamic pressure support power;
(3) rely on the lubrication pit of peripheral sealing liquid band and aiding support belt surface to be stored in pit by Lubricants, and time " tile kilning ", the Lubricants of storage is coated in again friction surface, improve friction and wear behavior, extend the service life of bearing.
(4) do not increase other parts, increase the load-carrying properties of bearing by means of only structural design, improve friction and wear behavior, there is structure simple, cost performance advantages of higher.
