Abstract
The utility model relates to a novel flywheel for a medium four-stroke gasoline engine, which is characterized in that the whole flywheel adopts an assembly type structure. The flywheel comprises a shell which is made of steel plate by stretch forming; wherein the middle of the shell is connected with a hub disk; the circumferential wall of the shell is provided with a cambered notch in which a steel magnet matched with the radian of the notch is mounted; a magnetic conductive plate matched with the radian of the steel magnet is mounted on the steel magnet; and a steel magnet holder matched with the shape of the cambered notch is sleeved on the steel magnet and the magnetic conductive plate. A balancing weight which has a radian equal to the inner diameter of the shell is fixed on the inner wall of the side of the shell opposite to the cambered notch. The steel magnet holder and the shell are fixed together by high-strength sunk screws, the balancing weight and the shell are fixed together by high-strength sunk screws, and the hub disk and the shell are fixed together by alloy rivets. The utility model has the advantages of compact structure, material saving and high strength, and nearly eliminates potential safety hazards related to the strength of the flywheel.
Description
Technical field
The utility model relates to a kind of gasoline engine ignition system, relates in particular to the flywheel on a kind of medium-sized four-stroke gasoline engine ignition system that is used for careless flat-bed machine.
Background technique
Medium-sized gasoline engine generator generally adopts four to be power towards petrol engine, and ignition system is respectively by the cast iron flywheel, two of high pressure packet combine, flywheel is the important constituent element of petrol engine, the flywheel of prior art, material is No. 20 pig iron, the casting trade mark 200, in the petrol engine system ignition advance angle control and rotary inertia matching effect are arranged, its cast iron flywheel is made and is adopted tratitional technology casting, a die casting moulding, its casting cycle complexity, big in molten steel quality control with manufacturing process control difficulty, cause it pore to occur, insufficient strength, hardness is unequal, and flywheel has the explosion possibility when high speed operation, and the user is had potential safety hazard.
Summary of the invention
The utility model main purpose is: at the existing deficiency of cast iron flywheel of prior art, thereby develop a kind of intensity height, processing technology is simple, the novel flywheel of medium-sized four-stroke gasoline engine that can eliminate safe hidden trouble.
Above-mentioned technical problem of the present utility model is mainly solved by following technical proposals: include the housing that adopts the steel plate drawing and forming, be connected with reel in the middle of the housing, the housing peripheral wall is provided with arc-shaped notch, the magnet steel that matches with the recess radian is housed in the arc-shaped notch, the magnetic conducting plate that matches with the magnet steel radian is housed above the magnet steel, is with the magnet steel frame that matches with the arc-shaped notch shape with the magnetic conducting plate outside at magnet steel; Be fixed with balancing weight with housing internal diameter identical radian measure at the inwall of housing arc-shaped notch opposite side.Whole flywheel adopts modular construction.
The technical solution of the utility model can be further perfect:
As preferably, fixedly connected with the high strength sunk screw between magnet steel frame, magnet steel, magnetic conducting plate and housing and housing and balancing weight and the housing.
As preferably, fixedly connected with the alloy rivet between reel and the housing.
As preferably, magnetic conducting plate and magnet steel frame are cast into one.Improve the integrity of its product.
The beneficial effects of the utility model are: because housing is the steel drawing and forming, fixedly connected by the alloy rivet between reel and the housing, fixedly connected by the high strength sunk screw between magnet steel frame, balancing weight, magnet steel, magnetic conducting plate and the housing; Therefore, whole flywheel structure compactness, technology is simple, economizes with material, and the intensity height has been eliminated the potential safety hazard because of flywheel intensity aspect.

Embodiment
Below by embodiment also in conjunction with the accompanying drawings, the technical solution of the utility model is further described in detail.
Embodiment:
To flywheel shown in Figure 5, whole flywheel adopts modular construction as Fig. 1.Adopt the housing 1 of steel plate drawing and forming, be connected with reel 7 in the middle of the housing, fixedly connected by alloy rivet 6 between reel and the housing; Peripheral wall by drawing and forming on the housing 1 is provided with arc-shaped notch 11, the arc of arc-shaped notch and flywheel shell are the same center of circle, the magnet steel 4 (seeing that Fig. 8 is to shown in Figure 9) that matches with the arc of recess is arranged in the arc-shaped notch, and the magnet steel outside is with magnet steel frame 2, so that the magnet steel location.The magnet steel frame adopts aluminium, and shape and arc-shaped notch are in full accord, and the radian above the magnet steel frame is identical with the housing external diameter, and is cast into one with magnetic conducting plate 8, magnetic conducting plate 5 be positioned at magnet steel frame 2 above, the bottom surface of magnetic conducting plate 5 contacts with magnet steel 4.The opposite side circumferential inner wall of housing arc-shaped notch 11 is installed with the balancing weight 5 that matches with the inwall radian, to adapt to the counterweight needs of flywheel.The radian of magnet steel 3, magnet steel frame 4, magnetic conducting plate 5 is adaptive mutually.Fixedly connected by the high strength sunk screw between magnet steel frame, magnet steel, magnetic conducting plate and the housing.
This novel flywheel is mainly used in IP71 grass flat-bed machine.
