Abstract
A kind of aerofoil leading edge dipleuraltype integration joint bearing, relate to technical field of aircraft structure design, handle the installation of joint for aerofoil leading edge, joint bearing settlement is between the first leading edge ribs with the second leading edge ribs and be fixedly connected with the first leading edge ribs, the second leading edge ribs.The inner chamber profile of the first leading edge ribs, the second leading edge ribs is inflection formula profile.Joint bearing is provided with the mounting hole installed and handle joint.The integral structure that manipulation joint bearing becomes dipleuraltype integrated with the leading edge ribs meter of both sides by the aerofoil leading edge dipleuraltype integration joint bearing that the utility model provides, the part of leading edge ribs and these two kinds of difference in functionalitys of joint bearing is combined together, both used as leading edge ribs, also use as joint bearing, decrease number of parts, alleviate structural weight, decrease support part and connect the face coordinated, improve the manufacturability of assembling, improve the efficiency of assembling.
Description
Technical field
The utility model relates to technical field of aircraft structure design, in particular to a kind of aerofoil leading edge dipleuraltype integration joint bearing.
Background technology
In airfoil structure design, certain movable wing leading edge is furnished with manipulation joint, handle in the circular hole on the bearing of jiont treatment between two leading edge ribs, common structure designs a joint bearing separately between two leading edge ribs, as shown in Figure 1, joint bearing is fastened on spar or rib part by bolt machinery.This version number of parts is many, and weight is large, connects the face coordinated many, and installing space between aerofoil leading edge ribs is narrow and small, and assembly process process is bad.The problem needing now solution badly how to design a kind of joint seat structure be installed in leading edge ribs, this joint bearing compared with prior art can reduce part quantity, alleviate structural weight, reduce and connect fitting surface quantity, be easy to install.
Utility model content
The purpose of this utility model is to solve above-mentioned deficiency of the prior art, aerofoil leading edge dipleuraltype integration joint bearing that provide a kind of quantity that is simple and reasonable, that can reduce part needed for structure, that alleviate structural entity weight.
The purpose of this utility model is achieved through the following technical solutions: a kind of aerofoil leading edge dipleuraltype integration joint bearing, it is characterized in that, comprise the first leading edge ribs, the second leading edge ribs, joint bearing, wherein, joint bearing settlement to be fixedly connected with the first leading edge ribs, the second leading edge ribs between the first leading edge ribs with the second leading edge ribs.
In such scheme preferably, the first leading edge ribs, the second leading edge ribs, joint bearing are formed in one structure.
In above-mentioned either a program preferably, the inner chamber profile of the first leading edge ribs, the second leading edge ribs is inflection formula profile.
In above-mentioned either a program preferably, joint bearing is provided with the mounting hole installed and handle joint.
The beneficial effect of aerofoil leading edge dipleuraltype integration joint bearing provided by the utility model is, structure is simple, easily manufactured, the part of leading edge ribs and these two kinds of difference in functionalitys of joint bearing is combined together, both used as leading edge ribs, also use as joint bearing, decrease number of parts, alleviate structural weight, decrease support part and connect the face coordinated, improve the manufacturability of assembling, improve the efficiency of assembling.

Fig. 3 is the structural blast figure that prior art works as center tap bearing.
Reference numeral:
1-first leading edge ribs, 2-second leading edge ribs, 3-joint bearing, 4-inner chamber profile.
Detailed description of the invention
In order to understand the aerofoil leading edge dipleuraltype integration joint bearing according to the utility model scheme better, be further elaborated explanation below in conjunction with the preferred embodiment of accompanying drawing to aerofoil leading edge dipleuraltype integration joint bearing of the present utility model.
As Figure 1-Figure 2, a kind of aerofoil leading edge dipleuraltype integration joint bearing that the utility model provides, comprise the first leading edge ribs 1, second leading edge ribs 2, joint bearing 3, wherein, joint bearing 3 to be arranged between the first leading edge ribs 1 with the second leading edge ribs 2 and to be fixedly connected with the first leading edge ribs 1, second leading edge ribs 2.First leading edge ribs 1, second leading edge ribs 2, joint bearing 3 are formed in one structure.The inner chamber profile of the first leading edge ribs 1, second leading edge ribs 2 is inflection formula profile.Joint bearing 3 is provided with the mounting hole installed and handle joint.
In the middle of prior art, as shown in Figure 3, the joint bearing 3 of aerofoil leading edge must be provided with the connecting panel fitted with aerofoil leading edge first leading edge ribs 1, second leading edge ribs 2, the connecting panel of joint bearing 3 offers fixed orifice, and by bolt/screw, joint bearing 3 is fixed in the first leading edge ribs 1, second leading edge ribs 2.This kind of mode permanent joint bearing 3 is adopted to need additionally to arrange connecting panel on joint bearing 3, and need additionally to add fastener when being connected with the first leading edge ribs 1, second leading edge ribs 2, in addition, the narrow space between leading edge ribs 1 and leading edge ribs 2, assembling difficulty.The aerofoil leading edge dipleuraltype integration joint bearing that the utility model provides is by joint bearing 3 and the machine-shaping of the first leading edge ribs 1, second leading edge ribs 2 one, decrease joint bearing 3 for the connecting panel of the first leading edge ribs 1, second leading edge ribs 2 and the fastener for being connected, alleviate integrally-built weight.Joint bearing 3 and the first leading edge ribs 1, second leading edge ribs 2 are set to integral structure, decrease the quantity of the part of assembling, improve the structural strength of structural entity.
In concrete use procedure, as shown in Figure 2, aircraft movable wing leading edge is handled on joint and is adopted joint support style of the present utility model.Handle in the circular hole of jiont treatment on joint bearing 3, joint bearing 3, first leading edge ribs 1 and the second leading edge ribs 2 all adopt aluminum alloy materials numerical control machine to add global formation.The outside face of the first leading edge ribs 1 and the second leading edge ribs 2 is aerodynamic configuration face, and inner chamber profile 4 is processed into the aspect of inflection formula, is convenient to the installation of skins front edges mounting plate nut.Width between first leading edge ribs 1 and the second leading edge ribs 2 is only had an appointment 40mm, and space is comparatively narrow and small, and aerofoil leading edge dipleuraltype integration joint bearing of the present utility model does not re-use mechanical fastener.Because joint bearing of the present utility model is integrated, number of parts is reduced to 1 by 3, alleviates structural weight, decreases support part and connects the face coordinated, improve the manufacturability of assembling, improve the efficiency of assembling.
More than be described in detail in conjunction with aerofoil leading edge dipleuraltype integration joint bearing specific embodiment of the present utility model, but be not to restriction of the present utility model, everyly according to technical spirit of the present utility model, technical scope of the present utility model is all belonged to any simple modification made for any of the above embodiments, also it should be noted that, comprise the combination in any between each part mentioned above according to the category of aerofoil leading edge dipleuraltype integration joint bearing technical scheme of the present utility model.
