Description
Technical field
The application belongs to aero-engine technology field, in particular to a kind of receipts oil ring anti-rotation location structure.
Background technique
Advanced aero engine, bearing fuel system much requires fuel feeding under ring, and supplies under the bearer ring of certain fulcrums
Oil circuit footpath must receive oil ring and axis in the structure of axially position and circumferential anti-rotation, by axis internal diameter by receiving oil ring and axle construction
It is limited with the structure size of collar radial thickness, meanwhile, for integrating the receipts oil ring of seal structure, the positioning for receiving oil ring is also determined
Obturaging gap isostructuralism can design.At present guaranteeing axis internal diameter and under the premise of axis radial thickness, oil ring and axis are being received
Anti-rotation location structure is only capable of taking the structure of axial anti-rotation and axial limiting, and receiving oil ring with axis is radially that clearance fit is close at two
Seal positioning.
As shown in Figure 1, bearing 11 is mounted on axis 12, receives oil ring 13 and axis 12 takes the knot of axial anti-rotation and axial limiting
Structure receives oil ring 3 in axial limiting by the nut 5 with rib 6, and realizes that the circumferential direction for receiving oil ring 3 and axis 2 is anti-by structure of grinding one's teeth
Turn.Receive the radial fit gap of oil ring 13 and axis 12, the spacing at two between sealing 14 and comb tooth 17 and right side sealing ring 14 it
Between spacing codetermined the deflection in the radial direction of comb tooth 17, when the spacing between comb tooth 17 and right side sealing ring 14 is larger
When, the deflection in the radial direction of comb tooth 17 is also larger.
Seal structure is integrated due to receiving oil ring, if dimension chain control is unreasonable when assembly and work operating, will cause to receive
Oil ring sealing is interfered with runway, serious for labyrinth gas seals to will lead to comb tooth and runway matrix touches to rub and causes spark or even axis
Hold the failures such as chamber kindling.
Summary of the invention
The purpose of the application is any of the above-described to solve the problems, such as there is provided a kind of receipts oil ring anti-rotation location structure.
The technical solution of the application is: a kind of receipts oil ring anti-rotation location structure comprising bearing, axis, the receipts oil with comb tooth
Ring, sealing ring, cupuliform locking plate and nut, bearing are installed on the outside of axis, receive oil ring and are installed on the inside of axis and the end by axis
Face axially position is received and sets spaced sealing ring between oil ring and axis, and cup type locking plate is axially inserted into the comb tooth one end for receiving oil ring, and
Cup type locking plate is relatively fixed to limit the rotation for receiving oil ring by nut and axis.
The oil ring anti-rotation location structure of the application realizes receipts oil ring under axis internal diameter and the limitation of collar radial thickness structure
With the purpose of design of axis circumferential direction anti-rotation and axially position, axial upper anti-rotation and positioning are devised in assembly bearing diameter of axle position rear end
The structure of end face nor affects on the structure of sealing ring minimum axis internal diameter, while axis external screw thread on collar radial thickness without influence
Cooperate with nut, so that cupuliform locking plate realizes receipts oil ring, axially nothing jumps, nut and the design for receiving oil ring anti-rotation, realization position
Afterwards, it avoids sealing element caused by receiving oil ring sealing structure axial jump and radial deflection and touches and rub.
Detailed description of the invention
In order to illustrate more clearly of technical solution provided by the present application, attached drawing will be briefly described below.It is aobvious and easy
Insight, drawings discussed below are only some embodiments of the present application.
Fig. 1 is the receipts oil ring anti-rotation location structure schematic diagram of the prior art.
Fig. 2 is the receipts oil ring anti-rotation location structure schematic diagram of the application.
Specific embodiment
To keep the purposes, technical schemes and advantages of the application implementation clearer, below in conjunction in the embodiment of the present application
Attached drawing, technical solutions in the embodiments of the present application is further described in more detail.
It is illustrated in figure 2 the receipts oil ring anti-rotation location structure sectional view of the application, the receipts oil ring anti-rotation positioning of this application
Structure includes bearing 21, axis 22, receives oil ring 23 (with comb tooth 28), sealing ring 24, cupuliform locking plate 25, nut 26.Bearing 21 is pacified
Outside loaded on axis 22 receives oil ring 23 and is installed on the inside of axis 22 and by 27 axially position of end face of axis 22, receive oil ring 23 with
Spaced sealing ring 24 is set between axis 22, cup type locking plate 25 is axially inserted into 28 one end of comb tooth for receiving oil ring 23, and cup type locking plate
25 is relatively fixed to limit the rotation for receiving oil ring 23 by nut 26 and axis 22.
Wherein, the minimum diameter of axis 22 is ф d1, and the maximum outside diameter of axis 22 is ф d2, axis 22 and 21 fitting area L0 model of bearing
The smallest radial ring thickness of axis 22 in enclosing is h1, and the smallest radial ring thickness of axis 22 is that (this is 22 Gewindefreistiche position of axis to h2
Set smallest radial size), above-mentioned size is that structure size is restricted requirement.
The positioning of axis 22 and receipts oil ring 23 and anti-rotation structure are arranged at axis 22 and 21 fitting area L0 of bearing and sealing ring 24
Rear end.
The receipts oil ring anti-rotation location structure of the application uses structure of grinding one's teeth, screw thread and the cup type locking plate of axis 22 and nut 26
Integrated positioning form, axis 22 and receipts oil ring 23 pass through axial structure of grinding one's teeth, while realizing circumferential anti-rotation, end after mounting
Face 27 will receive 23 one end axially position of oil ring, receive 23 other end of oil ring by cupuliform retainer ring 25,26 axially position of nut.Receive oil ring 23
Anti-rotation is realized by cup type locking plate 25 with nut 26.
The application's receives oil ring anti-rotation location structure suitable for the rotor under restricted structure and with the axial direction between rotation member
The design of anti-rotation axial positioning structure, soluble limit arrowhead are h1 h2.
The oil ring anti-rotation location structure of the application realizes receipts oil ring under axis internal diameter and the limitation of collar radial thickness structure
With the purpose of design of axis circumferential direction anti-rotation and axially position, axial upper anti-rotation and positioning are devised in assembly bearing diameter of axle position rear end
The structure of end face nor affects on the structure of sealing ring minimum axis internal diameter, while axis external screw thread on collar radial thickness without influence
Cooperate with nut, so that cupuliform locking plate realizes receipts oil ring, axially nothing jumps, nut and the design for receiving oil ring anti-rotation, realization position
Afterwards, it avoids sealing element caused by receiving oil ring sealing structure axial jump and radial deflection and touches and rub.
The above, the only specific embodiment of the application, but the protection scope of the application is not limited thereto, it is any
