According to the seal structure of the lubricating cavity of the engine, the effects of making the seal structure of the lubricating cavity of the engine simple and easy to process, prolonging the service life of the seal structure and saving cost can be achieved.
Description
Technical field
The utility model relates to engine art, especially, relates to a kind of sealing configuration of lubricating oil chamber of motor.
Background technique
In contemporary aeroengine air system, it is a key technology that oil pocket (fuel chamber, lubricating oil chamber) is obturaged.This technology is to preventing that combustion/lubricating oil from getting into air system and runner and ensureing that engine health plays an important role.
The front portion of aviation turboshaft engine utilizes the graphite box of obturaging to obturage at present, obturages with the comb tooth in its rear portion.But, obturage with the comb tooth and need introduce pressurized gas again, cause seal structure complicated, and comb tooth easy abrasion lost efficacy.Simultaneously, utilize the comb tooth to obturage, higher to the requirement on machining accuracy of part.
The model utility content
The utility model purpose is to provide a kind of sealing configuration of lubricating oil chamber of motor, with the sealing configuration complex structure that solves the lubricating oil chamber of motor in the existing technology, the technical problem that comb tooth easy abrasion lost efficacy, part is difficult to process.
For realizing above-mentioned purpose,, a kind of sealing configuration of lubricating oil chamber of motor is provided according to an aspect of the utility model; Motor comprises high-pressure air chamber, stator and rotor; Wherein, Spielpassung between first section of first end of stator and rotor, lubricating oil chamber and high-pressure air chamber connect through the gap between the Spielpassung each other; First end of stator is provided with screw thread, and the thread groove of screw thread and lubricating oil chamber connect.
Further, first of rotor section axially is provided with a plurality of grooves.
Further, groove is distributed in first section outer side wall of rotor.
Further, groove and lubricating oil chamber connect.
Further, the gap that cooperates with gap between rotor of stator is 0.2mm to 0.5mm.
Further, screw thread is an acme thread.
The utlity model has following beneficial effect:
Through the utility model, the lubricating oil cavity sealing structure that can reach motor is simple, and is easy to processing, prolongs the working life of sealing configuration and the effect of practicing thrift cost.
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 sealing configuration in lubricating oil chamber of the motor of the utility model preferred embodiment.
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, include high-pressure air chamber 2, lubricating oil chamber 7, stator 1 and rotor 3 in the motor.Be Spielpassung between first section of first end of stator 1 and rotor 3.Lubricating oil chamber 7 and high-pressure air chamber 2 gap between Spielpassung connects each other.For preventing that the lubricating oil in the lubricating oil chamber 7 from leaking, and is provided with two place's sealing configurations in motor.Wherein a place is: in high-pressure air chamber 2, be provided with the graphite box 5 of obturaging; The graphite gap of high-pressure air body between stator 1 and rotor 3 that the periphery of box 5 exists of obturaging flows to lubricating oil chamber 7, utilizes the draught head of high-pressure air that lubricating oil chamber 7 interior lubricating oil are obturaged.
Also be formed with cavity 4 between stator 1 and the rotor 3.Cavity 4 also connects with high-pressure air chamber 2 and lubricating oil chamber 7.The existence of cavity 4 makes the air pressure of the high-pressure air in the high-pressure air chamber 2 descend, and the decline of air pressure will influence the effect of obturaging to lubricating oil chamber 7.Therefore, be provided with other place's sealing configuration and further obturaged in lubricating oil chamber 7, specifically ask for an interview as follows.
First end of stator 1 is provided with screw thread 11, promptly this first end be with first section of rotor 3 be Spielpassung.The thread groove 111 and the lubricating oil chamber 7 of the screw thread 11 of first end of stator 1 connect.First section side-wall shaft of rotor 3 is to being provided with a plurality of grooves that are uniformly distributed with 31, and promptly this first section is that first end with stator 1 is a Spielpassung.First section the groove 31 and the lubricating oil chamber 7 of rotor 3 also connect.First section of first end of stator 1 and rotor 3 all near lubricating oil chamber 7.The gap of high-pressure air in the high-pressure air chamber 2 between cavity 4 inflow stators 1 and rotor 3, and then in the groove 31 of the thread groove 111 of inflow stator 1 and rotor 3.
When rotor 3 rotates; Because action of centrifugal force; The groove 31 of rotor 3 and the thread groove 111 interior high-pressure airs stirrings of stator 1 are flowed to lubricating oil chamber 7, utilize the draught head of high-pressure air to prevent the lubricating oil outflow in the lubricating oil chamber 7, thereby reach the effect of obturaging lubricating oil chamber 7.The centrifugal force of rotor 3 stirs high-pressure air, has further strengthened the obturage pressure of high-pressure air to lubricating oil chamber 7, need not to introduce pressurized gas in addition again, has simplified the structure of sealing configuration and has reduced cost.
In the present embodiment, the gap between stator 1 and the rotor 3 is D, and the number range of D is 0.2mm to 0.5mm.The screw thread 11 preferred acme threads that adopt of stator 1.
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.
