Abstract

The utility model discloses a bearing frame belongs to aeroengine spray tube technical field. The utility model discloses a split type structure, include: a plurality of force bearing rings, round pin axle, force bearing ring one end are provided with first ear seat, and one end is provided with second ear seat, and force bearing ring side ancient piece of jade, round, flat and with a hole in its centre both ends are provided with third ear seat, and the second ear seat of force bearing ring one end is installed rather than the first ear seat cooperation of adjacent force bearing ring to it is fixed through the round pin hub connection, a plurality of force bearing rings become bearing frame through the round pin hub connection, the whole ring -type that is of bearing frame, it is fixed that bearing frame passes through the installation of third ear seat, alleviate the casting cost and the degree of difficulty, improved the finished product qualification rate, can carry out the part to the part ablation condition and change bearing frame, saved manufacturing cost.

Description

A kind of heavy frame

Technical field

This utility model belongs to aero-engine Nozzle Design technical field and in particular to a kind of heavy frame.

Background technology

Heavy frame is one of main load-bearing frame of jet pipe, is the important parts of jet pipe, and existing heavy frame mostly is overall thin Wall foundry goods, because design of part is complicated, size is larger, and castability has high demands, and does not allow metallurgical imperfection to exist, therefore casts Difficulty is big, and product qualified rate is relatively low.If ablation, crackle in force bearing ring local location, force bearing ring one integral piece will be led to lose efficacy, will Jet pipe is made to lose efficacy.

Utility model content

The purpose of this utility model: in order to solve the above problems, the utility model proposes a kind of heavy frame, employ point Body formula design, easily manufactured, mitigate casting difficulty, save manufacturing cost.

The technical solution of the utility model: one kind holds stand, using split-type structural, comprising: multiple force bearing rings, bearing pin, Force bearing ring one end is provided with the first ear mount, and one end is provided with the second ear mount, and force bearing ring side wall two ends are provided with third ear seat, load The first ear mount cooperation that second ear mount of ring one end is adjacent force bearing ring is installed, and is connected by bearing pin；Multiple loads Ring connects into heavy frame by bearing pin, and described heavy frame is overall annular in shape, and heavy frame passes through third ear seat and installs fixation.

Preferably, described first ear mount is provided with fluting, and described fluting and the second ear mount coordinate.

Preferably, described first ear mount and the second ear mount are provided with manhole, between described manhole and described bearing pin Gap coordinates.

Preferably, the quantity of described force bearing ring is 4-20.

Preferably, the quantity of the third ear seat on described force bearing ring is 2-4.

This utility model beneficial effect: adopt split-type structural, structure is simple, alleviate casting cost and difficulty, improve Product qualified rate, can carry out local replacing force bearing ring for Partial ablation situation, save manufacturing cost.

Specific embodiment

For making purpose, technical scheme and advantage that this utility model is implemented clearer, below in conjunction with this utility model Accompanying drawing in embodiment, is further described in more detail to the technical scheme in this utility model embodiment.In the accompanying drawings, ad initio To the element that same or similar label represents same or similar element or has same or like function eventually.Described reality Applying example is a part of embodiment of this utility model, rather than whole embodiments.Embodiment below with reference to Description of Drawings It is exemplary it is intended to be used for explaining this utility model, and it is not intended that to restriction of the present utility model.New based on this practicality Embodiment in type, the every other enforcement that those of ordinary skill in the art are obtained under the premise of not making creative work Example, broadly falls into the scope of this utility model protection.Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail.

In description of the present utility model it is to be understood that term " " center ", " longitudinal ", " horizontal ", "front", "rear", The orientation of instruction such as "left", "right", " vertical ", " level ", " top ", " bottom " " interior ", " outward " or position relationship are based on accompanying drawing institute The orientation showing or position relationship, are for only for ease of description this utility model and simplify description, rather than instruction or hint indication Device or element must have specific orientation, with specific azimuth configuration and operation, therefore it is not intended that to this practicality The restriction of novel protected scope.

Below in conjunction with the accompanying drawings embodiment of the present utility model is described in detail, refers to Fig. 1 to Fig. 3；

One kind holds stand, using split-type structural, is made up of 4-20 force bearing ring 1 and bearing pin 2, and force bearing ring 1 one end is arranged There is the first ear mount 3, one end is provided with the second ear mount 4, the first ear mount 3 and the second ear mount 4 are respectively arranged with two manholes 7, And manhole 7 is radially distributed, manhole 7 is coordinated with bearing pin 2 gap；It is provided with fluting 6 between first ear mount 3, described Fluting 6 is coordinated with the second ear mount 4；

Force bearing ring 1 side wall two ends have 2 third ear seats 5 respectively, and the second ear mount 4 insertion of force bearing ring 1 one end is adjacent First ear mount 3 of force bearing ring, and be connected by bearing pin 2；Multiple force bearing rings 1 connect into heavy frame by bearing pin 2, described hold Power frame is overall annular in shape, and heavy frame passes through third ear seat 5 to be fixed with miscellaneous part installation.

This utility model is split-type structural, is formed by connecting by bearing pin by force bearing ring；Force bearing ring structure is simple, and size is relatively Little, alleviate casting cost and difficulty, improve product qualified rate, local replacing load can be carried out for Partial ablation situation Frame, saves manufacturing cost.

Last it is noted that above example is only in order to illustrating the technical solution of the utility model, rather than it is limited System.Although being described in detail to this utility model with reference to the foregoing embodiments, those of ordinary skill in the art should manage Solution: it still can be modified to the technical scheme described in foregoing embodiments, or wherein some technical characteristics are entered Row equivalent；And these modifications or replacement, do not make the essence of appropriate technical solution depart from each embodiment of this utility model The spirit and scope of technical scheme.
