Abstract
The utility model relates to a single-cylinder diesel engine speed regulation mechanism with an oil limiter and a speed regulation spring, which comprises the oil limiter, a speed regulation spring box, a speed regulation lever and a speed regulation rod, wherein the oil limiter is arranged on a gear chamber cover of a single-cylinder diesel engine, one end of the speed regulation rod is tightly locked with a hexagon nut through a clamp spring, and in addition, the upward and downward free gap of the speed regulation rod is regulated to the optimum degree for realizing the goal of stably regulating the speed. In addition, the speed regulation spring is provided with a fixed pin, the proper oil supply can be realized through extending and retracting the spring during the maximum oil supply, an engine can not generate black smoke, the oil limiter is arranged on the gear chamber cover, and the speed regulation spring box can realize the fixed oil limiting quantity of the oil limiter through a regulating screw. The speed regulation mechanism has the advantages that flexibility and sensitivity are realized, the smoke is not generated during the acceleration, in addition, the torque reserve is greater, and the block climbing capability is stronger. The dynamic property of the diesel engine is favorably enhanced, and the occurrence of black smoke generation phenomenon can be avoided.
Description
Technical field
The utility model relates to a kind of single cylinder diesel, especially a kind of speed regulating mechanism that can prevent the single cylinder diesel of over-emitting black exhaust, specifically a kind of single cylinder diesel speed regulating mechanism that has limit stoper and governor spring.
Background technique
At present, the speed regulating mechanism of domestic single cylinder diesel mainly is the centrifugal force that has the steel ball speed regulator to produce when reaching balance, and diesel engine could steady running.
When diesel engine quickens suddenly, promptly by moving the speed governing extension spring to the end suddenly under the idling mode, at this moment, under the effect of governor lever, the rapid big position of amount that pump rack is pushed to refuel, fuel delivery strengthens suddenly, substantially exceed the amount of fuel that declared working condition needs, made fuel oil mix disequilibrium, caused incomplete combustion, the phenomenon that over-emitting black exhaust occurs influences the smoke intensity and the economic indicator of diesel engine.Equally, under declared working condition, if diesel load increases suddenly, when diesel engine speed descends rapidly, pump rack can move to the direction that strengthens fuel delivery under the effect of lever equally, the generation of over-emitting black exhaust problem occurs, influences the complete machine service behaviour of diesel engine.
The model utility content
When being unexpected acceleration that exists at existing speed regulating mechanism, the purpose of this utility model produces the problem insufficient and that be short of power when increasing of burning because of load because of fuel delivery is excessive, design a kind of fuel delivery that both can limit in rating value, can carry out the single cylinder diesel speed regulating mechanism that has limit stoper and governor spring of fuel feeding compensation again automatically.
The technical solution of the utility model is: a kind of single cylinder diesel speed regulating mechanism that has limit stoper and governor spring comprises: be contained in oil-limiter, governor spring box on the gear chamber cover of single cylinder diesel, be located at governor lever and speed control rod on this governor spring box; Be provided with governor spring between the inwall of governor spring box and the governor lever, governor lever is provided with the fixing pin that is used for fixing described governor spring; One end of speed control rod is by jump ring and hexagon nut locking; Described gear chamber cover is provided with the adjusting screw that is used to adjust fuel delivery; The governor spring box makes described oil-limiter realize limit oil by described adjusting screw.
The cylinder diameter of described diesel engine is the 95-135 millimeter.
The utlity model has following advantage: in (1) speed regulating mechanism of the present utility model, an end of speed control rod is with the locking of jump ring and hexagon nut, and the easy on and off gap that makes speed control rod is to best degree, to realize stablizing the purpose of speed governing.In addition, governor spring has fixing pin, makes when maximum fuel feeding, by telescopic spring, can reach appropriate fuel feeding, allows not over-emitting black exhaust of motor; Oil-limiter is contained on the gear chamber cover, and the governor spring box makes oil-limiter fix the limit oil mass by adjusting screw; (2) speed regulating mechanism of the present utility model have soft, sensitive, quicken not smolder and torque reserve bigger, climb the stronger advantage of piece ability, help increasing the power character of diesel engine, can avoid the generation of over-emitting black exhaust problem.
Description of drawings
For the easier quilt of content of the present utility model is clearly understood, below the specific embodiment and in conjunction with the accompanying drawings of basis, the utility model is described in further detail, wherein
The structural representation of the single cylinder diesel speed regulating mechanism among Fig. 1 embodiment;
Fig. 2 is that the A of the single cylinder diesel speed regulating mechanism among Fig. 1 is to structural representation;
The structural representation of the gear chamber cover of the single cylinder diesel among Fig. 3 embodiment.
Embodiment
Below in conjunction with drawings and Examples the utility model is elaborated:
As Fig. 1-3, the single cylinder diesel speed regulating mechanism that has oil-limiter and governor spring of present embodiment comprises: be contained in oil-limiter, governor spring box 6, governor lever 2 and speed control rod 3 on the gear chamber cover of single cylinder diesel; The inwall of governor spring box 6 and governor lever 2 are provided with governor spring 1, and governor lever 2 is provided with the fixing pin 7 that is used for fixing described governor spring 1; One end of speed control rod 3 is by jump ring 4 and hexagon nut 5 lockings; Described gear chamber cover is provided with the adjusting screw that is used to adjust fuel delivery; Governor spring box 6 makes described oil-limiter realize fixing limit oil mass by described adjusting screw.
Obviously, the foregoing description only is for the utility model example clearly is described, and is not to be qualification to mode of execution of the present utility model.For those of ordinary skill in the field, can also make other changes in different forms on the basis of the above description.Here need not also can't give exhaustive to all mode of executions.And these belong to conspicuous variation or the change that spirit of the present utility model extended out and still are among the protection domain of the present utility model.
