Description
Technical field
The utility model belongs to engine component field, is specifically related to a kind of engine chain engine oil supplying assembly.
Background technique
Current petrol engine timing system all adopts silencing chain or roller chain, and oil pump is also driven by link chain mechanism, and chain system drives more reliable than traditional toothed belt, can realize and motor equivalent life simultaneously, avoids safeguarding.But the chain system of the existing most of motor only simple oil gas produced in engine operation process that relies on lubricates, and in chain chamber, there is not the lubrication of splashing form yet, chain system is is easily worn and torn, noise strengthens, when particularly the machine oil drain period is elongated, the impurity in machine oil can aggravate the wearing and tearing of chain.
Therefore, a kind of engine chain engine oil supplying assembly can forcing cooling and lubricating to engine chain system is needed.
Model utility content
In view of this, the purpose of this utility model is to provide a kind of engine chain engine oil supplying assembly can forcing cooling and lubricating to engine chain system;
Engine chain engine oil supplying assembly of the present utility model comprises the oil outlet that is arranged at engine cylinder-body and is connected to described oil outlet for lubricant oil being injected into the chain nozzle of engine timing chain; Described oil outlet is tapped hole, and described chain outer nozzle wall is provided with the outside thread coordinated with tapped hole;
Engine chain engine oil supplying assembly of the present utility model also comprises the sealing plate for gap between sealed chain nozzle and oil outlet; Described sealing plate is that rubber makes and is fixed on engine cylinder body sidewall, is provided with the via hole that chain nozzle is passed on sealing plate;
Further, described chain nozzle comprises body and oil nozzle integrated with body outer end; The aperture of described oil nozzle inner flow passage reduces gradually along oil flow direction;
Further, the body downward bending of described chain nozzle also turns forward, and described oil nozzle tilts outside motor;
Further, the runner in described chain nozzle body has necking down structure;
Further, described chain nozzle adopts metal calibration tube to make.
The beneficial effects of the utility model are: engine chain engine oil supplying assembly of the present utility model, chain nozzle and the interior existing oil duct of engine cylinder-body are threaded connection, when mounted, can chain nozzle be screwed in tapped hole, this Placement can effectively simplify engine assembly technique, existing oil duct in engine cylinder-body is utilized to be chain nozzle fuel feeding, ensure during installation that timing chain aimed at by chain cooling jet, ensure that lubricant oil can be sprayed on timing chain surface, enhance the lubrication effect of chain system, the cooling action simultaneously also served, and there is certain cleaning action to the impurity sticked on chain, engine chain engine oil supplying assembly of the present utility model changes the mode that engine chain relies on merely oil-air lubrication, define by oil gas and oil beam jetted acting in conjunction, enhance lubrication effect, also serve cooling and cleaning action simultaneously, greatly reduce the wearing and tearing of chain, effectively reduce operation noise, improve chain system working life.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, technical solutions of the utility model are further illustrated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is A-A sectional view in Fig. 1.
Embodiment
Fig. 1 is structural representation of the present utility model, as shown in the figure, engine chain engine oil supplying assembly in the present embodiment, comprises the oil outlet that is arranged at engine cylinder-body and is connected to described oil outlet for lubricant oil being injected into the chain nozzle of engine timing chain, described oil outlet is tapped hole 1, and described chain outer nozzle wall is provided with the outside thread coordinated with tapped hole 1, chain nozzle is connected with oil duct existing in engine cylinder-body, existing oil duct in engine cylinder-body is utilized to be chain nozzle fuel feeding, ensure during installation that timing chain aimed at by chain cooling jet, ensure that lubricant oil can be sprayed on timing chain surface, enhance the lubrication effect of chain system, the cooling action simultaneously also served, and there is certain cleaning action to the impurity sticked on chain, engine chain engine oil supplying assembly of the present utility model changes the mode that engine chain relies on merely oil-air lubrication, define by oil gas and oil beam jetted acting in conjunction, enhance lubrication effect, also serve cooling and cleaning action simultaneously, greatly reduce the wearing and tearing of chain, effectively reduce operation noise, improve chain system working life.
The engine chain engine oil supplying assembly of the present embodiment also comprises the sealing plate 2 for gap between sealed chain nozzle and oil outlet; Described sealing plate 2 makes for rubber and is fixed on engine cylinder body sidewall, and sealing plate 2 is provided with the via hole that chain nozzle is passed; The aperture of this via hole should be less than the external diameter of chain nozzle, ensures its sealability, and sealing plate 2 is by screw fixed installation and engine cylinder body sidewall.
In the present embodiment, described chain nozzle comprises body 3 and oil nozzle 5 integrated with body 3 outer end; The aperture of described oil nozzle 5 inner flow passage reduces gradually along oil flow direction, and therefore, lubricant oil will improve at the flow velocity at oil nozzle 5 place, ensures bulk range, and the throat structure at oil nozzle 5 place is conducive to the emitted dose controlling lubricant oil simultaneously.
In the present embodiment, body 3 downward bending of described chain nozzle also turns forward, described oil nozzle 5 tilts outside motor, here " front side " of indication refers to the direction perpendicular to engine crankshaft, body 3 is utilized to guide lubricant oil to flow downward, enable lubricant oil rely on self gravitation to carry out flowing thus improve the flow velocity of lubricant oil, oil nozzle 5 is obliquely installed and its lubricant oil sprayed can be made to disperse in space in drop event, improves the uniformity of lube range and lubrication.
In the present embodiment, the runner in described chain nozzle body 3 has necking down 4 structure, utilizes necking down 4 structure can accelerate lubricant oil, utilizes the lubricant oil of flowing fast to wash away chain nozzle inner walls, avoids impurity to block chain nozzle.
In the present embodiment, described chain nozzle adopts metal calibration tube to make, and metal calibration tube can occur bending and deformation under external force and shape, and adopts metal calibration tube making chain nozzle to be convenient to the injection direction of technician to chain nozzle and regulates.
What finally illustrate is, above embodiment is only in order to illustrate the technical solution of the utility model and unrestricted, although be described in detail the utility model with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can modify to the technical solution of the utility model or equivalent replacement, and not departing from the spirit and scope of technical solutions of the utility model, it all should be encompassed in the middle of right of the present utility model.
