Abstract
The utility model belongs to the technical field of diesel engine manufacture, in specific to a high-power diesel engine camshaft structure with adjustable phase angle, which comprises a diesel engine camshaft body, and a fuel cam, an exhaust cam for exhausting and an air inlet cam for inletting air sequentially arranged on the camshaft body; wherein the exhaust cam and the air inlet cam are designed to subdivision structures. The camshaft structure can effectively realize the adjustment of the phrase angles among the fuel cam, the air inlet cam and the exhaust cam, thereby ensuring the comparison experiments on the relations of various phrase angles among oil supply, air inlet and exhaust during the development experiment of the high-power diesel engine and improving the working performance of the diesel engine.
Description
Technical field
The utility model belongs to machinery manufacturing technology field, particularly a kind of high-power diesel engine camshaft structure of adjusting the phase angle.
Background technique
In the prior art, the camshaft structure of diesel engine generally comprises the camshaft body, and be successively set on fuel cam, exhaust cam and intake cam on the camshaft body, but exhaust cam and intake cam are closed design, make the phase angle between fuel cam, intake cam and the exhaust cam fix, can not make things convenient for and adjust separately effectively between the phase angle.Therefore for powerful diesel engine, in the trial-manufacturing process of model machine, can not carry out multiple phase angle relationship comparative trial between fuel feeding, air inlet and the exhaust to diesel engine preferably.
The model utility content
The purpose of this utility model is to overcome the deficiencies in the prior art, a kind of high-power diesel engine camshaft structure of adjusting the phase angle is provided, this camshaft structure can be realized the phase angle adjustment between fuel cam, intake cam and the exhaust cam effectively, thereby the comparative trial of multiple phase angle relationship between the fuel feeding when guaranteeing the high-power diesel engine development experiments, air inlet and the exhaust can improve the service behaviour of diesel engine.
In order to realize above-mentioned technical purpose, the utility model is realized by following technological scheme:
A kind of high-power diesel engine camshaft structure of adjusting the phase angle, comprise the cam shaft for diesel engine body, and be successively set on fuel cam on the camshaft body, be used for the exhaust cam of exhaust and be used for the intake cam of air inlet, described exhaust cam and intake cam are the split type structure design.
For split type exhaust cam and split type intake cam are connected on the camshaft body, described exhaust cam and intake cam connect as one by positioning dowel respectively.
For split type exhaust cam and split type air inlet gas cam are connected on the camshaft body, described exhaust cam and intake cam close the back by the fastening screw trip bolt sign indicating number and are fastenedly connected with the camshaft body.
For the convenience of processing, described fuel cam and camshaft body one process.
Compared with prior art, the beneficial effects of the utility model are:
The utility model is owing to design intake cam and exhaust cam for split type structure, make this intake cam and exhaust cam in 360 °, to locate arbitrarily as required, thereby the phase angle between realization fuel cam, intake cam and the exhaust cam is adjusted arbitrarily, make in the model machine Development and Trial process of diesel engine, can carry out the comparative trial of multiple phase angle relationship between fuel feeding, air inlet and the exhaust.
Description of drawings
Below in conjunction with the drawings and specific embodiments the utility model is described in detail:
Fig. 1 is a cam shaft for diesel engine structural representation described in the utility model.
Fig. 2 is the utility model intermediate fuel oil cam, intake cam and exhaust cam phase angle schematic representation.
Fig. 3 is that the intake cam of split type in the utility model, the sign indicating number of exhaust cam close schematic representation.
Embodiment
As shown in Figure 1, a kind of high-power diesel engine camshaft structure of adjusting the phase angle described in the utility model, comprise cam shaft for diesel engine body 1, and be successively set on fuel cam 2 on the camshaft body 1, be used for the exhaust cam 3 of exhaust and be used for the intake cam 4 of air inlet.As shown in Figure 2, described exhaust cam 3 and intake cam 4 are the split type structure design.In addition, for exhaust cam 3 and intake cam 4 with split type are connected on the camshaft body 1, as Fig. 1, shown in Figure 3, described exhaust cam 3 and intake cam 4 connect as one by positioning dowel 5 respectively; Described exhaust cam 3 and intake cam 4 then are to close the back by 6 yards of fastening screw trip bolts respectively to be fastenedly connected with camshaft body 1, and all are combined with four fastening screw trip bolts 6 on each exhaust cam 3 and the intake cam 4 and carry out sign indicating number and close.In addition, for the convenience of processing, described fuel cam 2 processes with camshaft body 1 one.
In Fig. 2, A is fuel cam 2 cornerites, and B is exhaust cam 3 cornerites, and C is intake cam 4 cornerites, and β is the phase angle between fuel cam 2 and the exhaust cam 3, and α is the phase angle between fuel cam 2 and the intake cam 4.The utility model is when diesel engine model machine development experiments, the intake cam 4 of split type structure design can be located arbitrarily in 360 ° as required with exhaust cam 3, thereby can realize that the phase angle between fuel cam 2, intake cam 4 and the exhaust cam 3 adjusts arbitrarily, make in the model machine Development and Trial process of diesel engine, can carry out the comparative trial of multiple phase angle relationship between fuel feeding, air inlet and the exhaust, service behaviour preferably be arranged to guarantee diesel engine.
The utility model is not limited to above-mentioned mode of execution, if various changes of the present utility model or modification are not broken away from spirit and scope of the present utility model, if these are changed and modification belongs within claim of the present utility model and the equivalent technologies scope, then the utility model also is intended to comprise these changes and modification.
