Abstract
The utility model relates to a separate lubrication type small universal petrol engine which belongs to the technical field of a petrol engine. The utility model mainly solves the technical problems that a small universal petrol engine with the prior art adopts a mixing lubrication mode, because of improper mixture ratio, the high heat load is applied on the petrol engine, the service life is short, the power is lowered, the operation is complicated, etc. The utility model has the technical scheme that the utility model comprises an oil tank, a carburetor, an air inlet pipe, an oil pipe, a starter, a back tank, a magneto generator, a crank shaft, a cylinder body, a piston, a fan, etc., wherein the oil tank is composed of a petrol tank and an engine oil tank; the back section of the crank shaft is provided with a screw thread which forms a worm screw shape; the lower part of the magneto generator on the back tank is provided with an engine oil pump on which an oil outlet pipe, an engine connecting oil tank pipe, a plunger, a worm wheel and a cam are arranged, wherein the plunger, the worm wheel and the cam are integral; the worm wheel is engaged with the screw thread on the crank shaft; the oil outlet pipe of the engine oil pump is communicated with the air inlet pipe through the oil pipe. The utility model can be widely used as matching power of engineering machines and gardening machines.
Description
Technical field: the utility model belongs to the technology of gasoline engine field, relates to a kind of small utility gasoline engine, particularly relates to a kind of machine oil and separates lubricated small utility gasoline engine with gasoline.
Background technique: the small utility gasoline engine of prior art, its lubricating system mostly adopt machine oil and gasoline blending lubricating system, and being about to machine oil and gasoline, to add in the same fuel tank gasoline feed machine according to certain proportioning mixing lubricated.With the 1E45F-2 petrol engine is example, and these facility have characteristics such as power height, noise be low.But because this machine lubrication system adopts the blending lubricating system, each continuous lubricating oil filling all will be with machine oil and gasoline according to certain proportioning mixing, troublesome poeration, in case and proportioning is improper very easily makes petrol engine produce high heat load and damage machine, the result reduces the working life and the power of petrol engine.
Summary of the invention: the technical problems to be solved in the utility model is, the prior art small utility gasoline engine adopts the blending lubricating system, the petrol engine high heat load that brings owing to proportioning is improper, and working life of causing thus is low, power descends and technical problem such as troublesome poeration.
The technological scheme of the utility model technical solution problem is, change the blending lubricating system of petrol engine into the separation lubricating system, it is to improve to realize that it comprises fuel tank, Carburetor, suction tude, oil pipe, starter, rear cabinet, magnetogenerator, bent axle, cylinder body, piston, fan etc. on the basis of prior art small utility gasoline engine that the utility model separates the lubricated type small utility gasoline engine; Its main points are that said fuel tank is made of petrol tank and two casings of sump, and the back segment of bent axle is provided with screw thread and is worm; Be provided with oil pump below the magnetogenerator on the rear cabinet, oil pump is provided with oil outlet tube, the tank tube and be plunger, worm gear and the cam of integrative-structure of meeting sb. at the airport; Threaded engagement on said worm gear and the bent axle; Said oil pump outlet pipe communicates with suction tude by oil pipe.
Too high for preventing fuel delivery, the tank tube of meeting sb. at the airport on the said oil pump is two, and one is oil inlet pipe, and another root is a return tube.
In order to make the oil pump fixation, said oil pump is fixedly supported on the rear cabinet.
The utility model separates lubricated working procedure, worm gear on the oil pump is by bent axle worm screw driven rotary, because worm gear top is the circuit cam structure, plunger, worm gear and cam are one, this structure is converted into rotatablely moving of bent axle the to-and-fro motion of plunger, thereby realize the pump functional oil of oil pump, the machine oil that oil pump sucks is sent into the suction tude of petrol engine after pressurization, machine oil and high speed gasoline gas are fully mixed form uniform mixed gas, the normal combustion that has guaranteed petrol engine is with lubricated.
Because oil pump adopts plunger, worm gear, cam to be structure as a whole, and be provided with an oil circuit that advances scene 2, when fuel delivery is higher, excessive machine oil will return fuel tank by return tube; Oil pump has guaranteed that with the adjustment of the variation realization fuel delivery of speed of crankshaft petrol engine makes the proportioning of gasoline and machine oil adjust automatically under different load and different rotating speeds simultaneously.
The utility model is compared with the petrol engine of blending lubricating system, has improved the lubricating condition of petrol engine, has reduced the heat load of petrol engine, has improved the use power and the working life of petrol engine, and easy to operate.
Description of drawings: Fig. 1, be the utility model structural representation;
Fig. 2, be the utility model oil pump structural representation;
Fig. 3, be the utility model Oiltank structure schematic representation.
Among the figure 1, piston 2, magnetogenerator 3, bent axle 4, starter 5, oil pump 6, rear cabinet 7, Carburetor 8, oil pipe 9, suction tude 10, fan 11, cylinder body 12, worm gear 13 cams 14, plunger 15, petrol tank 16, sump
Embodiment: with reference to the accompanying drawings, the utility model comprises fuel tank, Carburetor 7, suction tude 9, oil pipe 8, starter 4, rear cabinet 6, magnetogenerator 2, bent axle 3, cylinder body 11, piston 1, fan 10; Fuel tank is made of petrol tank 15 and 16 two casings of sump, and the back segment of bent axle 3 is provided with screw thread and is worm; Be provided with oil pump 5 below the magnetogenerator 2 on the rear cabinet 6, oil pump 5 is fixedly supported on the rear cabinet 6, and oil pump 5 is provided with oil outlet tube, two tank tubes of meeting sb. at the airport, and wherein: one is oil inlet pipe, another root is a return tube, and oil pump outlet pipe communicates with suction tude by oil pipe; Also be provided with the plunger 14, worm gear 12 and the cam 13 that are integrative-structure on the oil pump 5, the threaded engagement on worm gear 12 and the bent axle 3.
