Abstract
The invention provides a combined main oil way. The combined main oil way comprises a plurality of combined structures. Each combined structure comprises a steel pipe and flanges, wherein the two flanges are fixedly connected to the two ends of the steel pipe. Sealing structures are arranged on the contact faces of the steel pipes and the flanges. The combined structures are connected with and installed between multiple crankcase upper partition plates in series through the flanges at the two ends of the combined structures. The combined structures and the crankcase upper partition plates are alternately arranged. Sealing structures are arranged between the contact faces between the crankcase upper partition plates and the flanges connected with the crankcase upper partition plates. The combined main oil way has the beneficial effects that the combined oil way structure is adopted, the machining difficulty is lowered, and the machining hours and cost are reduced; due to the fact that the combined oil way can be independently manufactured, interchangeable use can be achieved on internal combustion engines of the same series; and due to the fact that deep hole machining or a special casting technology is avoided for the crankcases, the structural strength of a crankcase body is improved, and the rejection rate is reduced.
Description
Technical field
The invention belongs to internal-combustion engine oil duct technical field, especially relate to a kind of knockdown main oil gallery.
Background technique
The main oil gallery of existing general internal combustion engine is generally direct Drilling operation on crankcase, but the quality requirement of this method to cutter is higher, and processing time consuming, cost is higher.For big-and-middle-sized internal-combustion engine, because casing length is comparatively large, often beyond more than 1 meter, therefore directly Drilling operation has difficulties, and often to adopt when crankcase rough-cast in advance the method for a castingin thin-wall steel tube therein.
Especially for aluminium body, because steel pipe is different with the thermal expansion coefficient of aluminum substrate bi-material, therefore easily produce casting defect when casting, affect the structural strength of crankcase itself, technology stability is poor.Meanwhile, owing to requiring high to turbidity test when main oil gallery uses, for existing processing mode, all special cleaning need be carried out in the later stage to main oil gallery inside, the casting residue that the metal fillings produced with the descaling machine added-time or accumulated inside remain.
Summary of the invention
In view of this, the present invention is intended to propose a kind of knockdown main oil gallery, is particularly suitable for structure and the processing technology of typical main oil gallery on alternative current big-and-middle-sized internal-combustion engine.
For achieving the above object, technological scheme of the present invention is achieved in that
A kind of knockdown main oil gallery, comprise multiple composite structure, each described composite structure comprises steel pipe and flange, and two described flanges are fixedly connected on the two ends of steel pipe, and the surface of contact of steel pipe and flange is provided with sealing configuration; Multiple composite structure is installed in series between multiple crankcase upper clapboard by the flange at its two ends respectively, and composite structure and crankcase upper clapboard are arranged alternately, and is provided with sealing configuration between described crankcase upper clapboard and the surface of contact of connected flange.
Further, to adopt the mode of grafting to be combined into as a whole for two described flanges and steel pipe.
Further, described steel pipe is thin-wall steel tube, and described sealing configuration is O type rubber seal.
Further, flexible arrangement or integrated piston cooling nozzle on described flange.
Relative to prior art, the present invention has following advantage:
(1) adopt knockdown oil channel structure, reduce difficulty of processing, decrease machining period and cost; Also because this combination oil duct can manufacture separately, so be all used interchangeably with on a series of internal-combustion engine;
(2) on crankcase, to carry out deep hole processing owing to avoiding or adopt special casting technique, so improve the structural strength of casing, reducing reject rate.

Fig. 3 is structure of the present invention composition and scheme of installation.
Description of reference numerals:
1-flange, 2-O type rubber seal, 3-steel pipe, 4-crankcase upper clapboard, 5-crankcase.
Embodiment
It should be noted that, when not conflicting, the embodiment in the present invention and the feature in embodiment can combine mutually.
Below with reference to the accompanying drawings and describe the present invention in detail in conjunction with the embodiments.
A kind of knockdown main oil gallery of the present invention, as shown in Figure 1, 2, comprise multiple composite structure, each described composite structure comprises steel pipe 3 and flange 1, two described flanges 1 are fixedly connected on the two ends of steel pipe 3, the surface of contact of steel pipe 3 and flange 1 is provided with sealing configuration, thus is formed as an independently sealing channel structure; Multiple composite structure is installed in series between multiple crankcase upper clapboard 4 by the flange 1 at its two ends respectively, and composite structure and crankcase upper clapboard 4 are arranged alternately, and is provided with sealing configuration between described crankcase upper clapboard 4 and the surface of contact of connected flange 1; Thus the present invention defines the complete hermetic main oil-channel structure identical with prior art effect, last integral installation is fixed on crankcase.
It is as a whole that two described flanges 1 and steel pipe 3 adopt the mode of grafting to be combined into, and described steel pipe 3 is thin-wall steel tube, and described sealing configuration is O type rubber seal 2.
As required, flange 1 can also provide the position of installing piston cooling nozzle simultaneously, make the structure of piston cooling nozzle and arrange also to become simple comparatively flexibly; Or integrated piston cooling nozzle on flange 1.
Steel pipe 3 of the present invention is the normal structure on market, and flange 1 casts processing separately, and thus processing technology is simple, is easy to ensure the quality of products; Each several part manufactures separately, combination after and internal-combustion engine assemble; Do not need combustion motor body to carry out growing distance Drilling operation, do not need combustion motor body to carry out the special casting techniques such as castingin; Highly versatile, because this structure is independent processing, and then combines assembling with crankcase 5, as shown in Figure 3, thus has good versatility and interchangeability, be suitable for producing in enormous quantities.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
