Description
Technical field
The present invention relates to a kind of propeller hub and the connector of radome fairing.
Background technology
Radome fairing is typically made up of mounting disc and spinner, plays a part of rectification and protection propeller hub.Mounting disc connects with propeller hub
Connect, spinner is installed in mounting disc., it is necessary to a kind of connector connects radome fairing with propeller hub jointly when mounting disc is assembled with propeller hub
Connect.When propeller toward install on engine when, need to have hanging hole, to meet the lifting of propeller.It is existing by radome fairing and oar
The connector of hub connection is as shown in figure 1, two auricle 2 is one, its complex structure, processing difficulties with support 1；On auricle 2
The hanging hole 3 at end is used for propeller toward installation, the fixation being provided with the Y-piece 4 and Y-piece 4 of the lower end of auricle 2 on engine
Hole is used to be connected with propeller hub, and Y-piece 4 is thin with respect to propeller hub interface position, and in the environment of flight, Y-piece will bear very aircraft
Strong active force, it is easy to damage, causes service life short, and if checks less than being easier to fracture causes accident.
The content of the invention
The purpose of the present invention is exactly to solve the above-mentioned problems in the prior art, there is provided a kind of structure is relatively easy, plus
Easily, connecting portion is hardly damaged work, the propeller hub of long service life and the connector of radome fairing.
To achieve the above object, technical solution of the invention is：A kind of connector of propeller hub and radome fairing,
Including reducing support, auricle A, auricle B, nut A, nut B and pad；Support one end and radome fairing mounting disc interface endoporus phase
Matching, the end is provided with shaft shoulder A；Support the other end matches with propeller hub interface endoporus, and the end is provided with shaft shoulder B；Branch
Frame two ends are provided with screw thread；Auricle A and auricle B upper ends are provided with relative hole for hoist, and bottom is provided with and consolidating that support matches
Determine hole；Radome fairing mounting disc interface set is acted against on shaft shoulder A on support one end, and support is fixed on by pad and nut A
On the end；It is cased with auricle A, propeller hub interface and auricle B on support the other end successively from inside to outside, auricle A acts against shaft shoulder B
On, auricle A, propeller hub interface and auricle B are fixed on the other end of support by nut B.
Preferably, pin hole, nut A and nut B are diametrically had on the threaded two ends of described support
Corresponding position has pin hole；Nut A and nut B is fixed on support by pivot pin A and pivot pin B.Pivot pin A and pivot pin
B prevents nut A and nut B from being rotated along support and relaxed, and fixation is more reliable.
Auricle A and B and support are two body structures in of the invention, and auricle lower end, without Y-piece, its structure is relatively easy, point
Body is processed, and processing is simple, with good interchangeability, as long as changing parts therein, can just reach connection different model
The demand of radome fairing and propeller hub, and maintenance and replacing parts also become simple, its installation cost is low, convenience easy to maintenance.Oar
Hub is connected with whole support, and active force runs through whole support, and fixed reliability is high, is hardly damaged, long service life.

16.The other end of support 8 matches with the endoporus of propeller hub interface 14, and the end is provided with shaft shoulder B 17.The two ends of support 8 are provided with spiral shell
Line 18 and 19.Auricle A 9 and the upper ends of auricle B 11 are provided with relative hole for hoist 10, and bottom is provided with and consolidating that support 8 matches
Determine hole 20.Radome fairing mounting disc interface 15 is enclosed within the one end of support 8, is acted against on shaft shoulder A 16, by pad 7 and nut A 6
It is fixed on the end of support 8.It is cased with auricle A 9, propeller hub interface 14 and auricle on the other end of support 8 successively from inside to outside
B 11, auricle A 9 is acted against on shaft shoulder B 17, and auricle A 9, propeller hub interface 14 and auricle B 11 are fixed on support by nut B 12
On 8 the other end.Preferably, the He of pin hole 21 is diametrically had on the described threaded two ends of support 8
22, nut A 6 and the corresponding positions of nut B 12 have pin hole；Nut A 6 and nut B 12 are by pivot pin A 5 and axle
Pin B 13 is fixed on support 8.
Above-described embodiment is only preferred and exemplary, and those skilled in the art can do according to the spirit of this patent
Same technological improvement, these are all covered by the protection domain of this patent.
