Compared with prior art, the beneficial technique effect that the utility model is brought is shown：
1st, it can stop that be attached to the deep fat of runner plate working face transmits between adjacent two bearing shell by oil-isolating device, reduce
Into bearing shell deep fat amount while, the cold oil amount into bearing shell can be increased, not only contribute to reduce the working oil temperature of bearing,
Also help the oil film thickness between increase runner plate and bearing shell and improve the bearing capacity of bearing.In addition, being pushed away with conventional dynamic pressure
Power bearing is compared, and can prevent the deep fat of previous bearing shell outflow from entering latter bearing shell under the drive of runner plate, therefore can also subtract
The distance between small adjacent two bearing shell, so as to reduce the volume of thrust bearing on the whole, not only improves reduction thrust axis
The dimensional footprint held, advantageously reduces the manufacturing cost of thrust bearing again.One radial cavities, cavity are set in oil separating plate
Axial hole is set between top surface and oil separating plate upper surface, the cold oil of certain pressure is passed into cavity, cold oil is formed through axial hole
Jet directive mirror table lower surface, cold oil jet disturbing type runner plate face surface deep fat boundary layer and makes it be exchanged with cold oil, is increasing
In the case of big oil-isolating device and runner plate interplanar distance, above-mentioned effect can be also reached, so as to reduce the abrasion of oil-isolating device
Amount.
2nd, the ratio between width and depth of the axial hole of radial cavities and oil separating plate upper surface are 0.1 to 5 in connection oil separating plate,

Oil inlet pipe, or oil inlet pipe are to be formed by being provided with the oil separating plate through bottom surface and the bottom axial hole of radial slot bottom land,
The quantity in hole is 1 to 10, sets oil inlet pipe to be connected with the hole, and cold oil is conveyed into oil separating plate top radial slot.In section
Under stream effect, deep fat occurs to exchange strongly with cold oil in groove, so under larger spacing condition, it is possible to prevent deep fat with runner plate
Face is delivered to next thrust bearing shoe valve surface, so as to further reduce the wear extent of oil separating plate.
7th, because existing bearing shell can slightly adjust oil film thickness according to bearing load, therefore support frame passes through connector
The structure connected with bearing shell can slightly adjust the contact dynamics between oil separating plate and runner plate, so as to be conducive to improving oil removal effect
Really.
8th, oil separating plate is connected by flexible member with support frame, and oil separating plate and runner plate can be automatically adjusted by flexible member
Between contact dynamics, even if in the case that oil separating plate is used for a long time and there is certain abrasion, also ensure that oil removal effect, having
Beneficial to the service life for extending whole oil-isolating device；In addition, the structure will not also on the premise of ensureing to have preferable oil removal effect
Influence the rotation of runner plate.
9th, the quantity of flexible member is many, and many flexible members are arranged between oil separating plate and support frame, and the structure was both
So that stability of the oil separating plate on support frame more preferably, causes oil separating plate working face again（Oil removal face）In each position and runner plate connect
Touch degree is more balanced, can further improve oil removal effect, so as to further reduce the volume of whole thrust bearing.
