Abstract
A novel diesel generator set comprises a housing, a crank arranged in the housing, a crank gear arranged on the crank, a cam shaft, a cam gear arranged on the cam shaft and engaged with the crank gear, a first cam and a second cam fixedly arranged on the cam shaft, and a valve push rod with the lower end butted against on the first cam or the second cam, wherein the valve push rod is arranged outside the cylinder head of the diesel engine. Compared with the prior art in which the valve push rod is arranged inside the cylinder head of the diesel engine, the novel diesel generator set has the advantages of low work environment temperature, relatively low manufacture difficulty of the valve push rod and easy manufacture.
Description
Technical field
The utility model relates to a kind of novel diesel generator set, relates in particular to a kind of valve actuating push rod structure of diesel generating set.
Background technique
Diesel generating set is a kind of small power generation equipment, and it is to be that fuel is the dynamic power machine that prime mover drives generator for electricity generation with the diesel engine with diesel oil etc.A whole set of unit generally is made up of with parts such as storage battery, protective gear, emergent cabinets diesel engine, generator, control box, fuel tank, starting and control.
The working principle of diesel generating set is the Diesel Driven generator operation, is electric energy with the Conversion of energy of diesel oil.In diesel engine cylinder, fully mix with the high-pressure atomization diesel oil that oil nozzle ejects through the clean air after the air-strainer filtration, extruding lower volume at piston stroking upward is dwindled, temperature raises rapidly and reaches the burning-point of diesel oil, diesel oil is lighted, and mixed gas acutely burns, and volume expands rapidly, promote descent of piston, be called " acting ".Each cylinder is acting successively in certain sequence, and the thrust that acts on the piston has become the strength that promotes the bent axle rotation through connecting rod, thereby drives crankshaft rotating.With the coaxial installation of generator and crankshaft of diesel engine, just can utilize the rotation of diesel engine to drive the rotor of generator, utilize " electromagnetic induction " principle, generator will be exported induction electromotive force, just can produce electric current through the load circuit of closure.
Wherein valve actuating push rod is the important component part of the valve mechanism on the diesel engine, and its performance when work directly influences the performance of the distribution device of whole diesel generating set, directly influences the quality of whole generating unit.Yet valve actuating push rod is arranged on the inside of the cylinder head of diesel engine usually in the prior art, because cylinder head is higher in the ambient temperature in when work, therefore higher to the quality requirement of the manufacturing processing of valve actuating push rod, processing technology is comparatively complicated.
The model utility content
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of novel diesel generator set, and the outside that its valve actuating push rod is arranged on the cylinder head of diesel engine makes its processing more or less freely.
The utility model can be implemented by the following technical programs:
A kind of novel diesel generator set, it comprises casing, be arranged on bent axle in the described casing, be arranged on crankshaft gear, camshaft on the described bent axle, be arranged on the cam wheel that is meshed with described crankshaft gear on the described camshaft, be fixedly installed on first cam on the described camshaft and second cam, underpart pushes against valve actuating push rod on described first cam or second cam, and described valve actuating push rod is arranged on cylinder of diesel engine head outside.
One end of described valve actuating push rod is connected on the end of Rocker arm assembly, and the other end of described Rocker arm assembly is provided with the valve adjustments valve, and described Rocker arm assembly and valve adjustments valve are positioned at the top of cylinder of diesel engine head.
Compared with the prior art the utility model has following advantage:
Because valve actuating push rod of the present utility model is arranged on the outside of cylinder of diesel engine head, to compare operating ambient temperature low with being arranged on cylinder of diesel engine head inside in the prior art, therefore the manufacturing of valve actuating push rod required lowly relatively, processes more or less freely.
Description of drawings
Accompanying drawing 1 is a structural representation of the present utility model;
Wherein:
1, casing; 2, bent axle; 21, crankshaft gear; 3, camshaft; 31, cam wheel; 32, first cam; 33, second cam; 4, valve actuating push rod; 5, Rocker arm assembly; 6, valve adjustments valve; 7, tappet; 8, valve; 9, cylinder head.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is elaborated:
As shown in Figure 1, a kind of novel diesel generator set, it comprises casing 1, be arranged on the bent axle 2 in the described casing 1, be arranged on the crankshaft gear 21 on the described bent axle 2, camshaft 3, be arranged on the cam wheel 31 that is meshed with described crankshaft gear 21 on the described camshaft 3, be fixedly installed on first cam 32 and second cam 33 on the described camshaft 3, the underpart pushes against the tappet 7 on described first cam 32 or second cam 33, be fixedly connected on the valve actuating push rod 4 on the described tappet 7, described valve actuating push rod 4 is arranged on the outside of cylinder of diesel engine head 9.
Because valve actuating push rod 4 of the present utility model is arranged on the outside of cylinder of diesel engine head 9, compared with prior art operating ambient temperature is relatively low, and is therefore low relatively to the manufacturing requirement of valve actuating push rod 4, processes more or less freely.
The upper end portion of described valve actuating push rod 4 is connected on the end of Rocker arm assembly 5, and the other end of described Rocker arm assembly 5 is provided with valve adjustments valve 6, and described Rocker arm assembly 5 and valve adjustments valve 6 are positioned at the top of cylinder of diesel engine head 9.
When bent axle 2 rotations, because crankshaft gear 21 is meshed with cam wheel 31, therefore drive camshaft 3 rotations, be fixedly installed on first cam 32 and the also rotation thereupon of second cam 33 on the camshaft 3, make tappet 7 and valve actuating push rod 4 move up and down.Because the leverage of Rocker arm assembly 5, when valve actuating push rod 4 moved downward, 6 on valve adjustments valve moved upward, and drove valve 8 and closed.When valve actuating push rod 4 moved upward, 6 on valve adjustments valve moved downward, and drove valve 8 and opened.
The foregoing description only is explanation technical conceive of the present utility model and characteristics; its purpose is to allow the personage that is familiar with this art can understand content of the present utility model and is implemented; can not limit protection domain of the present utility model with this; all equivalences of being done according to the utility model spirit change or modify, and all should be encompassed in the protection domain of the present utility model.
