Abstract
The utility model provides a lubricating oil oil return connecting device, its includes two rectangle mounting discs, is two fixedly connected with bellows between the rectangle mounting disc, the corner sets of rectangle mounting disc has four mounting holes of equipartition. The utility model provides a lubricating oil oil return connecting device, simple structure is convenient for make, and effective reduction in production cost just can effectively reduce aviation piston engine's operation expense.
Description
Technical field
The utility model relates to mechanical field, particularly a kind of lubricating oil oil return connection set.
Background technique
Fig. 1 is a kind of structural representation of existing lubricating oil oil return connecting base, shown in Figure 1, in certain existing aviation piston engine, its lubricating oil pond is fixedly connected with middle casing, deceleration casing is connected with described lubricating oil pond by the lubricating oil oil return connecting base 1 shown in Fig. 1, described lubricating oil oil return connecting base 1 comprises a mounting disc 10 and a connecting head 11, and described mounting disc 10 is bolted on described deceleration casing, and described connecting head 11 is by canvas filler rubber flexible pipe and described lubricating oil pond.Because described canvas filler rubber flexible pipe exists aging hidden danger, therefore each tune-up all must be changed, and described canvas filler rubber flexible pipe storage requirement is strict, and the shelf life is short, also must carry out regular sampling examination in storage period, therefore safeguards, user cost is higher.
Model utility content
The technical problems to be solved in the utility model is to provide a kind of lubricating oil oil return connection set, to reduce or to avoid problem noted earlier.
For solving the problems of the technologies described above, the utility model proposes a kind of lubricating oil oil return connection set, it comprises two rectangle mounting discs, is fixedly connected with bellows between two described rectangle mounting discs, and the corner of described rectangle mounting disc is provided with four uniform mounting holes.
Preferably, described bellows has 8-12 ripple.
Preferably, described bellows and described mounting disc are welded to connect.
Preferably, the connecting length of described bellows and described mounting disc is more than or equal to 6mm.
A kind of lubricating oil oil return connection set provided by the utility model, structure is simple, is convenient to manufacture, and effectively can reduce cost of production, and effectively can reduce the operation expense of aviation piston engine.
Accompanying drawing explanation
The following drawings is only intended to schematically illustrate the utility model and explain, does not limit scope of the present utility model.Wherein,
Fig. 1 is a kind of structural representation of existing lubricating oil oil return connecting base;
Fig. 2 a is the structural representation of a kind of lubricating oil oil return connection set according to a specific embodiment of the present utility model;
Fig. 2 b is the A-A cross-sectional schematic of Fig. 2 a.
Embodiment
In order to there be understanding clearly to technical characteristics of the present utility model, object and effect, now contrast accompanying drawing and embodiment of the present utility model is described.Wherein, identical parts adopt identical label.
Fig. 2 a is the structural representation of a kind of lubricating oil oil return connection set according to a specific embodiment of the present utility model; Fig. 2 b is the A-A cross-sectional schematic of Fig. 2 a.Shown in Fig. 2 a, 2b, the utility model provides a kind of lubricating oil oil return connection set, and it comprises between two rectangle mounting discs, 2, two described rectangle mounting discs 2 and is fixedly connected with bellows 3.Two described rectangle mounting discs 2 are separately fixed on deceleration casing and lubricating oil pond, described bellows 3 provides closed lubricating oil path between two described rectangle mounting discs 2, so just overcome the flexible pipe of canvas filler rubber described in prior art storage requirement strict, shelf life is short, the defect that the maintenance cost of regular sampling examination is high also must be carried out in storage period, described bellows 3 can adopt commercially available corrugated stainless steel tubing, like this, in tune-up, as long as there are not the abnormal conditions such as crackle in described bellows 3, with regard to not needing, it is changed, also just user cost is reduced.
The corner of described rectangle mounting disc 2 is provided with four uniform mounting holes 21, can ensure that described rectangle mounting disc 2 is connected with deceleration casing and the stable of lubricating oil pond like this, the rectangular configuration of described rectangle mounting disc 2 can make described rectangle mounting disc 2 when area is less, provides enough operative positions and join strength still can to the described mounting hole 21 at four angles.
Described bellows 3 has 8-12 ripple, can ensure that described bellows 3 has enough ductility and can not be damaged in the process of installing described rectangle mounting disc 2 like this.
Described bellows 3 can be welded to connect with described mounting disc 2, can ensure the sealing of described bellows 3 and described mounting disc 2 joint like this.Certainly, described bellows 3 also by hurricane band clip connected, like this when defect appears in described bellows 3, only can change described bellows 3 with described mounting disc 2, and continues to use described mounting disc 2, thus can save Material Cost.
Described bellows 3 is more than or equal to 6mm with the connecting length L of described mounting disc 2, can guarantee the stable connection of described bellows 3 and described mounting disc 2 like this.
A kind of lubricating oil oil return connection set provided by the utility model, structure is simple, is convenient to manufacture, and effectively can reduce cost of production, and effectively can reduce the operation expense of aviation piston engine.
Although it will be appreciated by those skilled in the art that the utility model is described according to the mode of multiple embodiment, not each embodiment only comprises an independently technological scheme.So describe in specification be only used to clear for the purpose of; specification should integrally be understood by those skilled in the art, and regards technological scheme involved in each embodiment as the mode that mutually can be combined into different embodiment to understand protection domain of the present utility model.
The foregoing is only the schematic embodiment of the utility model, and be not used to limit scope of the present utility model.Any those skilled in the art, the equivalent variations done under the prerequisite not departing from design of the present utility model and principle, amendment and combination, all should belong to the scope of the utility model protection.
