Abstract
The utility model provides a crankcase body for a horizontal single-cylinder petrol engine. A crank shaft installing hole, a starting motor installing hole, a cam shaft installing hole and a balance shaft installing hole are formed on the crankcase body; a cylinder is mounted in the crankcase body; axes of the cylinder and the crank shaft installing hole are in the same horizontal plane, and the axis of the cam shaft installing shaft is positioned on the upper side of the axis of the cylinder. Since the axes of the cylinder and the crank shaft installing hole are in the same horizontal plane, and the axis of the cam shaft installing shaft is positioned on the upper side of the axis of the cylinder, the height of the crankcase body and the whole engine is reduced, the occupied space is narrowed, the gravity center is lowered, the vibration and the noise in the process of high-speed rotation are reduced, and the service life of the engine is prolonged.
Description
Technical field
The utility model relates to a kind of parts of single cylinder petrol engine, particularly a kind of horizontal single cylinder gasoline engine crank box body.
Background technique
Existing single cylinder gasoline engine crank box body referring to Fig. 1, offers crankshaft installed hole 4, actuating motor mounting hole 6, camshaft mounting hole 3, trunnion shaft mounting hole 5 on casing 1, and is provided with cylinder 2 on casing 1.Because the axis of the cylinder 2 on the existing single cylinder gasoline engine crank box body 1 becomes an angle that makes progress (being generally 25 °) with the horizontal plane at 4 axis places, crankshaft installed hole, and camshaft mounting hole 3 is arranged at the downside of cylinder 2 axis.Therefore, the crankcase body of this kind mode of structure not only can make the height of the casing 1 of crankcase obviously increase, be unfavorable for the layout of the generator set supporting in the confined space with it, and make the upper shift of gravity center of whole motor, vibration aggravation in the process of running up, increase the vibration noise of motor, reduced the working life of motor.
The model utility content
For overcoming the deficiencies in the prior art, the utility model provide a kind of rational in infrastructure, highly low, occupy little space, vibrate the horizontal single cylinder gasoline engine crank box body little, that noise is low.
The technological scheme that its technical problem that solves the utility model adopts is: offer crankshaft installed hole, actuating motor mounting hole, camshaft mounting hole and trunnion shaft mounting hole on crankcase body, and be provided with cylinder on casing; It is characterized in that: described cylinder-bore axis and crankshaft installed axially bored line are in the same level face, and camshaft mounting hole axis is positioned at the upside of cylinder-bore axis.
The beneficial effects of the utility model are: it is rational in infrastructure, because cylinder-bore axis and crankshaft installed axially bored line are in the same level face, and camshaft mounting hole axis is positioned at the upside of cylinder-bore axis, thereby reduced the height of crankcase body and whole motor, dwindled and taken up room, reduce center of gravity, reduced vibration and noise in the process that runs up, the working life of having improved motor.
Description of drawings
Fig. 1 is the structural representation of existing single cylinder gasoline engine crank box body;
Fig. 2 is a structural representation of the present utility model.
Among the figure: 1 is that casing, 2 is that cylinder, 3 is that camshaft mounting hole, 4 is that crankshaft installed hole, 5 is that trunnion shaft mounting hole, 6 is the actuating motor mounting hole.
Embodiment
Below in conjunction with accompanying drawing the utility model is further specified.
A kind of horizontal single cylinder gasoline engine crank box body described in the utility model as shown in Figure 2, offers camshaft mounting hole 3, crankshaft installed hole 4, trunnion shaft mounting hole 5 and actuating motor mounting hole 6 on crankcase body 1, be provided with cylinder 2 in a side of locating body 1; The axis 4 in the axis of cylinder 2 and crankshaft installed hole 4 is in the same level face, and the axis of camshaft mounting hole 3 is positioned at the axis upside of cylinder 2.The utility model has reduced the height of crankcase 1 body and whole motor effectively, has dwindled taking up room, and has reduced center of gravity, has reduced vibration and noise in the process that runs up, the working life of having improved motor.
