Abstract
A kind of intershaft bearing side direction rotating oil supply device, is characterized in that: described intershaft bearing side direction rotating oil supply device, comprises outer shaft, interior axle, intershaft bearing, horizontal coaxial nozzle, taper bush, taper oil dam, stator oil circuit; Wherein: outer shaft is connected by intershaft bearing with interior axle; Horizontal coaxial nozzle and outer shaft are assembled into one, and taper oil dam, horizontal coaxial nozzle and the taper bush being positioned at horizontal coaxial nozzle rear portion define the radial oil feed line increased gradually; Stator oil circuit is positioned at taper bush outside.Advantage of the present utility model: intershaft bearing side direction rotating oil supply device described in the utility model, side direction is with the another kind of lubrication strategies turning the lower design of fuel feeding, manufacture cost achieves intershaft bearing, make can continue to use ripe bearing under different operating mode and design environment, avoid the research and development of new bearing.
Description
Technical field
The utility model relates to oil inlet and oil return and the lubricating structure of intershaft bearing, particularly a kind of intershaft bearing side direction rotating oil supply device.
Background technique
Intershaft bearing is the stick roller bearing being positioned at inside and outside between centers, as the fulcrum of outer shaft on interior axle, such design not only can reduce the quantity of bearings casing, alleviate integrally-built weight, be irreplaceable structure especially in the dual rotors system of whirlpool spray axial flow engine, gas turbine.In the complete machine structure of motor, combustion engine, by general arrangement, such fuel supply path under interior shaft rear end-Nei axle axocoel-stub carrier ring can be realized.In the double rotor testpieces only having fan, gas compressor, due to Equipment, interior shaft rear end shutoff, under stub carrier ring, fuel feeding scheme is infeasible.
Model utility content
The purpose of this utility model is under the conventional ring of intershaft bearing in the infeasible situation of fuel feeding scheme, achieve a kind of by turning the device of nozzle for oil return with the same of outer shaft integrated design, realize the lubrication of intershaft bearing, ensure that intershaft bearing normally works, spy provides a kind of intershaft bearing side direction rotating oil supply device.
The utility model provides a kind of intershaft bearing side direction rotating oil supply device, it is characterized in that: described intershaft bearing side direction rotating oil supply device, comprises outer shaft 1, interior axle 2, intershaft bearing 3, horizontal coaxial nozzle 4, taper bush 5, taper oil dam 6, stator oil circuit 7;
Wherein: outer shaft 1 is connected by intershaft bearing 3 with interior axle 2; Horizontal coaxial nozzle 4 and outer shaft 1 are assembled into one, and taper oil dam 6, horizontal coaxial nozzle 4 and the taper bush 5 being positioned at horizontal coaxial nozzle 4 rear portion define the radial oil feed line increased gradually; It is outside that stator oil circuit 7 is positioned at taper bush 5.
With side direction oilhole on described outer shaft 1.
Nozzle, outer shaft integrated design, outer shaft adopts ladder-type design, self-assembling formation oil pocket, the design distinguished of nozzle is in the stator nozzle of routine, adopt flush type horizontal nozzles, one is assembled into outer shaft, form side direction oil supply gallery, conical bearing external bushing simultaneously before nozzle after taper oil dam-horizontal nozzles-nozzle defines the radial fuel supply path increased gradually, stator nozzle ejection lubricating oil during work outside axle, and oily dam, nozzle, bearing sleeve turns with outer shaft is same, the lubricating oil sprayed is collected on oil dam, by horizontal flow velocity and the centrifugal vector acting in conjunction of radial direction, realize flowing and the lubrication of lubricating oil, oil return is naturally got back to stepped shaft oil pocket and is discharged by the side direction oilhole on outer shaft.
Advantage of the present utility model:
Intershaft bearing side direction rotating oil supply device described in the utility model, side direction is with the another kind of lubrication strategies turning the lower design of fuel feeding, manufacture cost achieves intershaft bearing, make can continue to use ripe bearing under different operating mode and design environment, avoid the research and development of new bearing.
Accompanying drawing explanation
Below in conjunction with drawings and the embodiments, the utility model is described in further detail:
Fig. 1 is intershaft bearing side direction rotating oil supply device structural representation.
Embodiment
Embodiment 1
Present embodiments provide a kind of intershaft bearing side direction rotating oil supply device, it is characterized in that: described intershaft bearing side direction rotating oil supply device, comprises outer shaft 1, interior axle 2, intershaft bearing 3, horizontal coaxial nozzle 4, taper bush 5, taper oil dam 6, stator oil circuit 7;
Wherein: outer shaft 1 is connected by intershaft bearing 3 with interior axle 2; Horizontal coaxial nozzle 4 and outer shaft 1 are assembled into one, and taper oil dam 6, horizontal coaxial nozzle 4 and the taper bush 5 being positioned at horizontal coaxial nozzle 4 rear portion define the radial oil feed line increased gradually; It is outside that stator oil circuit 7 is positioned at taper bush 5.
With side direction oilhole on described outer shaft 1.
Nozzle, outer shaft integrated design, outer shaft adopts ladder-type design, self-assembling formation oil pocket, the design distinguished of nozzle is in the stator nozzle of routine, adopt flush type horizontal nozzles, one is assembled into outer shaft, form side direction oil supply gallery, conical bearing external bushing simultaneously before nozzle after taper oil dam-horizontal nozzles-nozzle defines the radial fuel supply path increased gradually, stator nozzle ejection lubricating oil during work outside axle, and oily dam, nozzle, bearing sleeve turns with outer shaft is same, the lubricating oil sprayed is collected on oil dam, by horizontal flow velocity and the centrifugal vector acting in conjunction of radial direction, realize flowing and the lubrication of lubricating oil, oil return is naturally got back to stepped shaft oil pocket and is discharged by the side direction oilhole on outer shaft.
As shown in Figure 1, stator part is stator oil circuit, and all the other are rotating component.During assembling in the horizontally mounted outer shaft axis hole of horizontal nozzles, outside is pressed into oily dam, and the horizontal nozzles the other end and lining overlap.During work, rotating component high speed rotating, the lubricating oil ejected from oil circuit collects guiding through oily dam, enters horizontal nozzles, then connects the taper guiding of lining, and lubricating oil will get rid of into bearing by oil nozzle, realize lubrication.Lubricating oil flows into oil pocket naturally, and the horizontal hole on outer shaft realizes oil return.
