Description
Technical field
The present invention relates to gas turbine mechanical System design technology field, a kind of more particularly to gas turbine central cone passes
Dynamic device flow deflector structure.
Background technology
Base bearing entreats in cone transmission device and primarily serves the effect for bearing radial load, lubrication in the gas turbine
The quality of effect directly influences the performance of gas turbine drive system.The lubrication of base bearing is generally provided by lubricating oil nozzle, by
It is limited in structure, lubricating oil nozzle cannot be lubricated directly to base bearing side spray, it may be necessary to which tortuous oil circuit could reach main shaft
It holds, this by certain pressure, makes lubricating oil enter base bearing, finally play lubrication with regard to Structure of need optimization oil circuit design
Effect.
By taking gas turbine central cone transmission device as an example, lubricating oil is after the nozzle in left side sprays, edge under the action of the centrifugal force
Drive bevel gear flows to the right.The speed that base bearing surpasses ten thousand turns with per minute during the work time rotates, lubricating oil with taper to
Base bearing side spray, it is considerably less or extremely difficult to actually enter the lubricating oil of base bearing, needs to design a flow deflector structure at this time,
Lubricating oil is made to enter base bearing by flow deflector, and then improves main bearing lubrication cooling effect.
The content of the invention
The purpose of the present invention is lubricating oil is made to enter base bearing by flow deflector, and then main bearing lubrication cooling effect is improved,
A kind of gas turbine central cone transmission device flow deflector structure is provided.
The present invention provides a kind of gas turbine central cone transmission device flow deflector structures, it is characterised in that：The combustion
Gas-turbine central cone transmission device flow deflector structure is evenly equipped with the aperture of Φ 1 on flow deflector structure, it is ensured that lubricating oil from aperture and
Horizontal axis is in 10~30 ° of angles, sprays to base bearing, gives base bearing fuel feeding；Drive bevel gear and flow deflector are interference fit, are prevented
Only it is rotated at work.
The aperture of 6 Φ 1 of design and the angle of horizontal axis are preferably 15 ° on the flow deflector structure.
The aperture for being evenly equipped with Φ 1, number are 3~9.
Gas turbine central cone transmission device flow deflector structure, is placed between lubricating oil nozzle and base bearing, mounted on actively
On bevel gear, making lubricating oil, along drive bevel gear, (inner wall has 3 ° tiltedly under the action of the centrifugal force after the nozzle lubricating oil in left side sprays
Degree) it flows to the right, lubricating oil is made to enter base bearing by flow deflector, and then improves main bearing lubrication cooling effect.
Advantages of the present invention：
Gas turbine central cone transmission device flow deflector structure of the present invention increases substantially main bearing lubrication cooling
Effect, application result of the flow deflector structure on the gas turbine also indicates that, can improve the functional reliability of base bearing, not yet send out
Now due to lubricant effect is bad base bearing is caused to be scrapped, promote economic benefit.
Description of the drawings
Below in conjunction with the accompanying drawings and embodiment the present invention is described in further detail：
Fig. 1 is gas turbine central cone transmission device flow deflector structure structure diagram；
Fig. 2 is gas turbine central cone transmission structures schematic diagram.
