Description
Technical field
The invention belongs to sliding bearing technical field, relates in particular to a kind of band axial direction oil-recovery tank and directly lubricate tilting bush
Bearing.
Background technique
Sliding bearing is widely used in high-speed overload equipment such as in Turbo-generator Set, to meet because of its large carrying capacity
The environmental requirement Turbo-generator Set of minimum discharge pursue ultimate attainment efficiency thus to high parameter large capacity develop, rotor weight and
The increase of bearing span requires the sliding bearing for providing rotor bearing to have excellent rotor dynamics.
Usually there are two types of fuel system for sliding bearing, and immersion type lubrication and directly lubrication, the former makees because of the stirring of oil supply tank
It is usually higher than the latter with its power consumption and bearing liner temperature.Directly lubrication is there are two types of typical structure: forward position slotted L EG bearing and with spray
Spill the bearing of block assembly.
The forward position fluting tilting-pad bearing of the companies such as Kingsbury and Toshiba, it is characterized in that being opened up in tile fragment forward position
Directly supply the oil-feed tank of cold oil, the fuel-displaced outage by between tile fragment of tile fragment takes away, defect be swung with tile fragment it is close
Wear-out failure easily occurs for seal and atomizer.
The structure with sprinkling block between tile fragment that the companies such as Kingsbury, Waukesha, John Crane use, it is cold
Oil is brought lower tile fragment by dedicated sprinkling block assembly radial spray to axle journal and is lubricated, defect be the hot oil on the fuel-displaced side of upper tile fragment not
The cold oil mixing that evitable and sprinkling block assembly sprays.
With further increasing for axle journal linear velocity and load, the above two sealing ring and atomizer for directly lubricating bearing
Easily generation wear-out failure and bearing shell are fuel-displaced does not have the defects of oil guide groove and sealing oil edge are easily mixed with sprinkling block cold oil, to continue to mention
The bearing capacity of high bearing need to make further innovation to the structure for directly lubricating bearing, this is exactly the first heart of the invention.
Summary of the invention
The purpose of the present invention is providing a kind of band axial direction oil-recovery tank in view of the above shortcomings directly to lubricate tilting-pad bearing,
This bearing can be improved reliability towards high-speed overload field and reduce bearing liner temperature.To achieve the above object, the present invention provides
Following technical solution:
A kind of band axial direction oil-recovery tank directly lubricates tilting-pad bearing, including several tile fragments, is equipped with sprinkling between the tile fragment
Block, the sprinkling block spray cold oil within the scope of the certain angle along tile fragment oil inlet side tangential direction；The fuel-displaced side of tile fragment
Tiling is equipped with oil-recovery tank and oil resistance side；The oil-recovery tank is axially extending.
Further, the sprinkling block sprays cold oil in 0 °~20 ° angular ranges of tile fragment oil inlet side tangential direction.
Further, the tile fragment oil inlet side is equipped with oil film wedge groove.
Further, the sprinkling block top is equipped with inclined-plane, and the inclined-plane is equipped with several oil spit holes, and the oil spout is small
Hole is for spraying cold oil.
Further, several oil spit holes on the inclined-plane are axially distributed.
Further, the oil spit hole on the inclined-plane is equipped with 3~20 according to bearing size size.
Further, the oil-recovery tank width range is 5mm~20mm or the angular range in opposite axle center is 5 °~15 °.
Further, the oil-recovery tank is arcuate structure.
Further, the oil resistance hem width degree range is 5mm~20mm or the angular range in opposite axle center is 5 °~15 °.
The beneficial effects of the present invention are:
1, cold oil is directly sprayed by sprinkling block along tile fragment oil inlet side tangential direction, and inclined-plane, inclined-plane are processed into sprinkling block top
On sprinkling aperture and tile fragment oil inlet side triangular angular range be 0~20 ° of small generator rotor angle, it is good into cold oil effect.
2, the fuel-displaced side of tile fragment has axial oil-recovery tank and oil resistance side, and upper tile fragment oil return is not mixed into down with sprinkling block cold oil
Tile fragment, direct high lubricating effect.

Fig. 2 is using present invention sprinkling block inclined-plane side structure schematic diagram；
In attached drawing: 1- axle journal, 2,8- tile fragment, 3- oil-recovery tank, 4- oil resistance side, 5- sprinkling block, 6- cold oil, 7- tile fragment alloy
Layer.
Specific embodiment
With reference to the accompanying drawing with specific embodiment, the present invention is described in more detail, but the present invention is not limited to
Following embodiment.
Embodiment:
See attached drawing 1~2.A kind of band axial direction oil-recovery tank directly lubricates tilting-pad bearing, including several tile fragments 2, the tile fragment 2
Between be equipped with sprinkling block 5, the sprinkling block 5 along within the scope of the certain angle of 2 oil inlet side tangential direction of tile fragment injection cold oil 6；
The tangential direction on that side when i.e. injection 6 direction of cold oil is approximately towards 2 oil inlet of tile fragment can have certain angle spray with tangent line
It penetrates, can achieve well into cold oil effect, to be got well compared to existing radial spray in this way.Cold oil 6 under the action of jet power,
Into the gap of axle journal 1 and tile fragment 2, lubrication and cooling are realized.
The tiling of the fuel-displaced side of the tile fragment 2 is equipped with oil-recovery tank 3 and oil resistance side 4；The oil-recovery tank 3 is axially extending.Cold oil 6
Wedge gap between axle journal 1 and tile fragment 2 sets up dynamic pressure oil film, and temperature increases after lubrication, and existing bearing does not have oil return
Slot 3, cold oil after heating and the cold oil just sprayed mixing, reduce cooling effect, and the cold oil after the heating of this bearing is from fuel-displaced
When side soon comes out, oil-recovery tank 3 will be encountered, is returned from oil-recovery tank 3, the cold oil mixing for avoiding and just spraying, cooling and profit
Sliding effect is more preferable, and oil resistance side 4, which plays, hinders cold oil back to sprinkling block 5.
The sprinkling block 5 is along injection cold oil 6 in 0 °~20 ° angular ranges of 2 oil inlet side tangential direction of tile fragment.It sprays cold
The tangential direction on that side when oily 6 directions are approximately towards 2 oil inlet of tile fragment, can there is certain angle injection with tangent line, 0 °, 5 °,
10 °, preferably no more than 20 °, cold oil is made to have the power of tangential direction injection.
2 oil inlet side of tile fragment is equipped with oil film wedge groove.Oil film wedge groove is equivalent to does a chamfering in 2 oil inlet side of tile fragment,
The opening of oil inlet increases in this way, and cold oil is facilitated to inject.
5 top of sprinkling block is equipped with inclined-plane, and the inclined-plane is equipped with several oil spit holes, and the oil spit hole is for spraying
Penetrate cold oil 6.Inclined-plane is convenient to process oil spit hole.
Several oil spit holes on the inclined-plane are axially distributed.Porous injection cold oil, effect are more preferable.
Oil spit hole on the inclined-plane is equipped with 3~20 according to bearing size size.Oil spit hole quantity will be according to axis
Selection of dimension is held, is selected in 3~20.
3 width range of oil-recovery tank is 5mm~20mm or the angular range in opposite axle center is 5 °~15 °.The oil return
Slot 3 is arcuate structure, is conducive to oil return.4 width range of oil resistance side is 5mm~20mm or the angular range in opposite axle center is
5 °~15 °.
The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations
