Except top described purpose, feature and advantage, the utility model also has other purpose, feature and advantage.To do further detailed explanation to the utility model with reference to figure below.
Description of drawings
The accompanying drawing that constitutes the application's a part is used to provide the further understanding to the utility model, and illustrative examples of the utility model and explanation thereof are used to explain the utility model, do not constitute the improper qualification to the utility model.In the accompanying drawings:
Fig. 1 is the structural representation of the utility model preferred embodiment;
Fig. 2 is the structural representation of the turbine disk of the utility model preferred embodiment; And
Fig. 3 is another embodiment's of the utility model a structural representation.
Embodiment
Embodiment to the utility model is elaborated below in conjunction with accompanying drawing, but the multitude of different ways that the utility model can be defined by the claims and cover is implemented.
Referring to Fig. 1 and Fig. 2, the turbo machine of the utility model comprises the turbine disk 3, turbine blade 10, guide plate 2 and stator 4.The sectional shape of this turbine disk 3 roughly is folding shape, and first end of the turbine disk 3 is connected with first end of rotor 11, and second end of rotor 11 connects turbine blade 10.Form a turbine disk chamber 1 between the relative stator 4 of the turbine disk and the turbine disk 3.
The turbine disk 3 comprise first section 31 of being connected with rotor 11, by first section 31 extend and with second section 32 of first section 31 approximate vertical and by second section 32 extend and with the 3rd section 33, the three sections 33 of first section 31 almost parallel be the core wheel place of the turbine disk.
This guide plate 2 is arranged between the adjacent stator 4 of the turbine disk 3 and the turbine disk 3, thereby is divided into first cavity 1 and second cavity 9 to the cavity between the turbine disk 3 and the stator 4.Be processed with bolt hole on the guide plate 2, guide plate 2 passes bolt hole through bolt 61 and is fixed on the stator 4.Be provided with Sealing between this bolt retaining head and the guide plate 2; The sealing part makes cooled gas get into behind the turbine disk cavity not can be directly to get into first cavity 1 from the space of bolt hole; Make at first the flow through core wheel place in turbine disk chamber 1 of cooled gas, to reach the effect in the highest core wheel zone of abundant chilling temperature; On the other hand; The cooled gas that Sealing also prevents to flow to the turbine disk 3 one sides is directly counter from the space of bolt hole again behind the turbine disk chamber 1 that just gets into the turbine disk 3 one sides to flow outflow; Promptly form minor loop; To prevent the cooled gas turbine disk 3 of can not all flowing through, realize the cooling of the whole turbine disk 3, reduce the utilization ratio of cooled gas.
The sectional shape of this guide plate 2 is close with the shape of the turbine disk 3, and is provided with near the turbine disk 3.Like this; The gap that forms between the guide plate 2 and the turbine disk 3 makes when cooled gas flows between the guide plate 2 and the turbine disk 3 about equally, guarantees that the thickness of air-flow is basic identical; Thereby guaranteed the cooled gas turbine disk 3 of at the uniform velocity flowing through; And can not form the dead angle that cooled gas flows in the corner of the turbine disk 3, make the turbine disk 3 coolings evenly, the utilization ratio of cooled gas improves greatly.
Be set to the narrow flow path 21 towards core wheel place, turbine disk chamber between the adjacent stator 4 of the guide plate 2 and the turbine disk, this stream guarantees the flow direction after cooled gas gets into turbine disk chamber, and cooled gas flows to core wheel place, turbine disk chamber earlier core wheel is cooled off.Because the highest, the mechanical load of the temperature at core wheel place is maximum in the turbine disk, environment is the most abominable, at first the core wheel of cooling turbine dish 3 zone can guarantee whole cooling effect.
Be used for the bolt 61 that guide plate 2 is fixed on the stator 4 is processed into hollow structure, the interior bone in the bolt 61 of this hollow is as cooled gas entry port 6.Bolt 61 is used for forms the cooled gas entry port, can reduce the hole of offering at the adjacent stator 4 of the turbine disk, like this, it is dual-purpose that being used on stator 4 and the guide plate 2 passed bolt hole one hole of bolt 61, can improve the mechanical strength of the adjacent stator 4 of the turbine disk.
Leave flow outlet 5 between rotor 11 and the stator 4.This flow outlet 5 is set to the labyrinth outlet, and promptly the flange of rotor 11 gos deep in the groove of stator 4.Like this, flow outlet 5 makes cooled gas discharge first cavity 1 in the turbine disk 3 backs of flowing through.When the cooled gas of not supplying with or supplying with on a small quantity, the air pressure in first cavity 1 can be less than air pressure outside the chamber, and at this moment hot gas can instead flow in first cavity 1 outside the chamber, and the labyrinth outlet is set, and can effectively prevent the anti-stream of hot gas.Simultaneously; The labyrinth flow outlet also can improve the utilization ratio of cooled gas, after promptly cooled gas gets in first cavity 1; Because little, the path length of bore of flow outlet 5; Make cooled gas not flow out fast, in turbine disk chamber 1, form overstocking to a certain degree, make that cooling effect is better, the cooled gas utilization ratio is higher.
Referring to Fig. 3, as other mode of execution, this cooled gas entry port 6 can be opened on the sidewall of stator 4 and narrow flow path 21 position adjacent, and connects with narrow flow path 21.Offer cooled gas entry port 6 separately, can more conveniently operate,, can not influence the fixedly bolt 61 of guide plate 2, can guarantee that bolt 61 and guide plate 2 do not become flexible at switch or when adjusting cooled gas air-flow big or small.
The utility model also provides a kind of motor, and above-mentioned turbo machine is installed in this motor.This motor can be installed on the aircraft, and on other practical machine.
The preferred embodiment that the above is merely the utility model is not limited to the utility model, and for a person skilled in the art, the utility model can have various changes and variation.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
