Abstract
The utility model belongs to aeroengine testing technique, concretely relates to rotary disk is experimental with preceding journal coupling structure. Rotary disk is experimental with preceding journal coupling structure passes through the axle head nut and overlaps the tooth and connect including switching sleeve, axle head nut, gland nut and switching section, the preceding axle journal and the switching sleeve of rotary disk, and switching sleeve and switching section pass through gland nut to be connected, and switching section and coupling shaft pass through the screw connection. The utility model discloses preceding axle journal has proposed the connection structure that preceding axle journal and coupling shaft are new with connecting shaft connecting structure, can realize testpieces and rotation test attachment of devices function, guarantee the rotary disk pass turn round reliably and axial, radical location reliable to rotation test carries out. After using this structure, solved guaranteeing under the unchangeable prerequisite of front axle neck structure, with coupling shaft's connection problem, the accurate centrifugal stress state of testpieces in the engine that reproduce.
Description
Technical field
The utility model belongs to aero-engine test technology, is specifically related to a kind of rotating disk test and connects structure with front axle journal.
Background technology
When whirl test done by aircraft engine wheel disc, quote exchanging structure to realize the connection testing part and testing installation, to load speed of rotation. For the rotating disk of axle journal before band, owing to front axle journal does not install the structure formation of limit, bolt hole, therefore when warranty test part structure without any changes, when front axle journal and testing installation are connected, it is necessary to special structure form is connected with the reliable of equipment with warranty test part.
Fig. 1 is the connection structure meridian plane schematic diagram of existing front axle journal with testing installation. This structure is made up of switching sleeve 2, pin 3 and Coupling Shaft 4. Front axle journal 1 is assemblied on switching sleeve 2, is connected by pin 3, and switching sleeve 2 is connected with Coupling Shaft 4 by screw. This structure can realize the connection function testing part and spin test facility, to carry out whirl test.
Seeing from Fig. 1 and Fig. 2 contrast, former test part connects structure and needs front axle journal is added work, and punches, and destroys the structure formation of front axle journal, i.e. the virgin state of structure, different with the structure formation in engine.
Practical novel content
Practical novel object: provide a kind of test part that can realize when without any changes, ensures the loading front same connecting structure for connecting shaft of axle journal reliably of spin test facility.
The technical solution of the utility model: a kind of rotating disk test connects structure with front axle journal, it comprises switching sleeve, shaft end nut, hold-down nut and switching section, the front axle journal of rotating disk and switching sleeve are connected by shaft end nut and cover tooth, switching sleeve and switching section are connected by hold-down nut, and switching section and Coupling Shaft are connected by screw or pin.
Described shaft end nut is provided with locking plate.
Described hold-down nut is self-locking out structure.
Advantageous Effects: the same connecting structure for connecting shaft of axle journal before the utility model, propose front axle journal and the new connection structure of Coupling Shaft, the connection function testing part and spin test facility can be realized, ensure that rotating disk torsion pass location reliable and axial, radial is reliable, to carry out whirl test. After applying this structure, under solving the constant prerequisite of journal structure before guarantee, with the connection problem of Coupling Shaft, accurate reproduction test part centrifugal stress state within the engine.
Accompanying drawing explanation
Fig. 1 is the connection structure meridian plane signal of existing front axle journal;
Fig. 2 is former front journal structure schematic diagram;
Fig. 3 is that the test of the utility model rotating disk connects structural representation with front axle journal;
Wherein, axle journal before 1; 2 switching sleeves; 3 pins; 4 Coupling Shaft; 5 hold-down nuts; 6 switching sections; 7 Coupling Shaft; 8 locking plates; 9 shaft end nuts; 10-overlaps tooth.
Embodiment
Below in conjunction with drawings and Examples, the utility model is described further:
Referring to Fig. 3, the test of the utility model rotating disk is connected structure with front axle journal and is realized effective connection of front axle journal and Coupling Shaft by switching sleeve, shaft end nut, hold-down nut and switching section. The test of the utility model rotating disk connects structure with front axle journal and comprises switching sleeve, shaft end nut, locking plate, hold-down nut and switching section. The front axle journal 1 of rotating disk and switching sleeve 2 are connected by shaft end nut 9 and cover tooth, and switching sleeve 2 and switching section 6 are connected by hold-down nut 5, and switching section 6 and Coupling Shaft 7 are connected by screw.
Reliable for ensureing structure centering, front axle journal 1 needs to ensure certain tight degree with the radial fit face of switching section 6 with switching sleeve 2, switching sleeve 2, and tightly degree is not easily excessive for this, crosses conference and causes dismounting difficulty; Switching sleeve 2 transmits moment of torsion with front axle journal 1 by cover tooth, and switching section 6 and switching sleeve 2 are rubbed torsion pass by hold-down nut; Connecting the rotation that structure prevents shaft end nut 9 by locking plate 2, hold-down nut 5 is designed to self-locking out structure formation to be prevented from rotating simultaneously.
Connection structure of the present utility model, it is proposed that front axle journal and the new connection structure of Coupling Shaft, it is possible to realize the connection function of test part with spin test facility, ensure rotating disk torsion pass reliable and axially, radial location reliably, to carry out whirl test. After applying this structure, under solving the constant prerequisite of journal structure before guarantee, with the connection problem of Coupling Shaft, accurate reproduction test part centrifugal stress state within the engine.
The utility model can be applicable in the whirl test in aircraft engine development work.
