Abstract
The utility model discloses one and start owner's erection joint, comprise thrust pin (1) joint body (2) and auricle (3), described thrust pin (1) and joint body (2) are integrated, described thrust pin (1) inserts an installing hole on engine, bears motor power load and course, side direction inertial load.Thrust pin and joint body are integrated into a part by the utility model, adopt titanium alloy forging processing, namely alleviate construction weight, turn improve the power transmission efficiency of joint, decrease number of parts and the assembling binding face of assembling simultaneously, reduce assembly difficulty, improve assembly precision.
Description
Technical field
The utility model belongs to aeroplane structure design, relates to one and starts owner's erection joint.
Background technology
Start owner's erection joint thrust pin and joint to be fabricated structure both at home and abroad at present, do not accomplish the joint body integrated design by thrust pin and band auricle.Fabricated structure joint bears the vertical and lateral load of engine, and thrust pin bears motor power and course, lateral load, and each part stress is simple, and connected by securing member between part, design difficulty is relatively low.
Utility model content
The technical problems to be solved in the utility model is, the engine erection joint of a kind of thrust pin and auricle and joint body integrated design is provided, this engine erection joint can either meet transmits motor power load and other inertial load requirement, compare composite engine erection joint, alleviate construction weight again, reduce assembly difficulty simultaneously, improve assembly precision.
For the technical solutions of the utility model that solve the problem provide one to start owner's erection joint, comprise thrust pin 1 joint body 2 and auricle 3, described thrust pin 1 is integrated with joint body 2, described thrust pin 1 inserts an installing hole on engine, bears motor power load and course, side direction inertial load.
Preferably, described thrust pin 1 is straight pin, bears motor power load and course, side direction inertial load; Described auricle 3 is web folder muscle formula structure, and the upper and lower edge strip of auricle bears and draws/compressive load, and auricle web bears shear-type load, and described joint body 2 also comprises rib and web for web folder muscle formula structure, and rib bears and draws/compressive load, and web bears shear-type load.
Thrust pin and joint body are integrated into a part by the utility model, adopt titanium alloy forging processing, namely alleviate construction weight, turn improve the power transmission efficiency of joint, decrease number of parts and the assembling binding face of assembling simultaneously, reduce assembly difficulty, improve assembly precision.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in more detail, wherein:
Fig. 1 starts owner's erection joint schematic diagram;
Fig. 2 starts owner's erection joint position view;
Fig. 3 starts owner's erection joint and engine connection diagram;
Fig. 4 starts owner's erection joint and other anatomical connectivity schematic diagrames of hanging.
Detailed description of the invention
Below the utility model is described in further detail.
One starts owner's erection joint 4, and its position is positioned at hanging 8 foremost, assists erection joint 5 together with engine, and be suspended on by engine 6 below wing 9, concrete type of attachment is shown in Fig. 2.
One starts owner's erection joint 4, it is characterized in that, it is shaping by machining after the forging of thrust pin 1, joint body 2 and auricle 3 three part one, and wherein thrust pin 1 is straight pin, bears motor power load and course, side direction inertial load; Auricle 3 is web folder muscle formula structure, and the upper and lower edge strip of auricle bears and draws/compressive load, and auricle web bears shear-type load, joint body 2 is also web folder muscle formula structure, and comprise rib and web, rib bears and draws/compressive load, web bears shear-type load, and concrete form is shown in Fig. 1.
One starts owner's erection joint, and it is connected with engine 6 and is, starts owner's erection joint two auricles 3 to be respectively connected with engine 6 by pull bar 10, bears that engine is vertical, side direction inertial load and engine rolling moment; An installing hole on thrust pin 1 insertion engine 6, bear motor power load and course, side direction inertial load, concrete type of attachment is shown in Fig. 3.
One starts owner's erection joint, it is connected is with hanging 8, owner's erection joint top is started to be connected with hanging front-axle beam 11, start to be connected with hanging left side wall 12 on the left of owner's erection joint, start to be connected with hanging right side wall 13 on the right side of owner's erection joint, start to be connected with hanging bottom girder 14 on the downside of owner's erection joint, concrete type of attachment is shown in Fig. 4.
One starts owner's erection joint, and its posting scheme is, motor power load, course load act on thrust pin 1, after joint body 2 spreads, be passed to the hanging bottom girder 14 being attached thereto and connecing; Engine vertical load, lateral load act on auricle 3, are passed to joint body 2 through the upper and lower edge strip of auricle, are passed to hanging front-axle beam 11 and hanging bottom girder 14 after joint body 2 spreads.
The reason that the utility model reduces construction weight and assembly difficulty is: thrust pin and joint body are designed to an one-piece parts, because this reducing Assembly part and assembling binding face, reduce assembly difficulty, improve engine installation accuracy, and compare fabricated structure, structure is simple, and cost is low.
