Abstract
The utility model relates to the technical field of engines, in particular to an embedded type cam shaft mechanism of a VBF engine. The embedded type cam shaft mechanism comprises a rotary shaft, the rotary shaft is provided with two independent embedded type cams, and each embedded type cam is fixed to the rotary shaft according to the valve timing size; each embedded type cam is provided with an oil jet channel, the rotary shaft is provided with an engine oil channel used for oil filling, and the engine oil channel is communicated with each oil jet channel. According to the embedded type cam shaft structure of the VBF engine, the mechanism is convenient to machine, has the advantages of being simple in structure, reasonable in design, low in manufacturing cost and the like, and provides the best lubricating guarantee for the engine at different rotation speeds.
Description
Technical field
The utility model relates to technical field of engines, particularly the inserted camshaft mechanism of a kind of VBF motor.
Background technique
Current existing motorcycle engine cam adopts integrated manufacture, and as shown in Figure 1, it comprises rotatingshaft 1 to its structural drawing, and rotatingshaft 1 is provided with cam 2, cam 2 and rotatingshaft 1 integrated setting.The manufacture cost of the engine cam of this structure is high, and difficulty of processing is large, and cam easily weares and teares, thereby has reduced service life of aeroengine.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and a kind of simple in structure, reasonable in design, the inserted camshaft mechanism of the nonabradable VBF motor of cam is provided.
For achieving the above object, the technical solution adopted in the utility model is: the inserted camshaft mechanism of a kind of VBF motor described in the utility model, comprise rotatingshaft, rotatingshaft is provided with two independently inserted cams, and each inserted cam is fixed on rotatingshaft according to port timing size; Described each inserted cam is provided with injection oil duct, and rotatingshaft is provided with the oil passageway for oiling, and oil passageway sprays oil duct with each and is communicated with.
Further, described rotatingshaft is provided with the bearing support for rotatingshaft rotation.
Further, the quantity of described inserted cam is 2.
Adopt after said structure, the utility model beneficial effect is: the inserted camshaft mechanism of a kind of VBF motor of the present utility model, it is easy to process.When using the utility model, the machine oil that oil pump ejects, by oil passageway, due to high pressure, directly by spraying oil duct, spray, pressure lubrication cam, cam face temperature is reduced rapidly, and after cam operating conditions is in use improved, cam is not easy to wear, thereby improve the service condition of motor, reach the working life that extends motor.The utlity model has simple in structure, reasonable in design, the advantage such as fabricating cost is low.
Accompanying drawing explanation
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, forms the application's a part, but does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, illustrative examples wherein and explanation are only used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 2, the inserted camshaft mechanism of a kind of VBF motor described in the utility model, comprises rotatingshaft 1, and rotatingshaft 1 is provided with two independently inserted cams 2, and each inserted cam 2 is fixed on rotatingshaft 1 according to port timing size; Described each inserted cam 2 is provided with and sprays oil duct 3, and rotatingshaft 1 is provided with the oil passageway 4 for oiling, and oil passageway 4 sprays oil duct 3 with each and is communicated with.
It should be noted that described rotatingshaft 1 is provided with the bearing support 5 for rotatingshaft 1 rotation.
Quantity that it should be noted that described inserted cam 2 is 2.
When using the utility model, the machine oil that oil pump ejects, by oil passageway, due to high pressure, directly by spraying oil duct, spray, pressure lubrication cam, cam face temperature is reduced rapidly, and after cam operating conditions is in use improved, cam is not easy to wear, thereby improve the service condition of motor, reach the working life that extends motor.The utlity model has simple in structure, reasonable in design, the advantage such as fabricating cost is low.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
