Abstract
The utility model discloses a kind of petrol engine flywheel, comprise wheel disc and be arranged on the gear ring on described wheel disc periphery, on the end face of described wheel disc, the joint that is positioned at described wheel disc and described gear ring is evenly distributed with several sector units, and described sector unit is concentric with described wheel disc.The petrolic flywheel of the utility model, on the end face of wheel disc, the joint that is positioned at wheel disc and gear ring is evenly distributed with several sector units, thus the quality of flywheel can be increased, because the rotary inertia of flywheel is directly proportional to the quality of sector unit, the increase of sector unit quality result in the increase of Rotary Inertia of Flywheel.Again due to the increase of Rotary Inertia of Flywheel, in the middle of engine test monitor procedure, can find that engine speed fluctuations obviously reduces, there is not abnormal shake in motor.
Description
Technical field
The utility model belongs to petrol engine field, particularly a kind of petrol engine flywheel.
Background technique
Flywheel is as one of the key components and parts of motor, and its Main Function comprises the energy storing engine running and the starting torque transmitting starter motor, and the flywheel of large inertia can also reduce the fluctuation of speed of motor simultaneously.
The design of flywheel current mainly comprises the matched design in the matched design of flywheel ring gear and starter motor gear ring, wheel friction face and clutch friction face.And the design consideration not relevant to the rotary inertia of flywheel, in engine test process, therefore easily cause engine speed fluctuations comparatively large, engine abnormity is shaken.
Model utility content
Technical problem to be solved in the utility model is to provide one and has large rotating inertia, can reduce the petrol engine flywheel of engine speed fluctuations.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is:
A kind of petrol engine flywheel, comprises wheel disc and is arranged on the gear ring on described wheel disc periphery, and on the end face of described wheel disc, the joint that is positioned at described wheel disc and described gear ring is evenly distributed with several sector units, and described sector unit is concentric with described wheel disc.
Preferably, described sector unit is three, and the angle of the projection on the end surface of the center of this sector unit and the described end face line of centres is 120 °.
Preferably, the end face of described end face and the perpendicular distance of described end face are 10mm to described sector unit dorsad.
Preferably, the outside diameter of described sector unit is 274.4mm, and interior circular diameter is 245mm.
Preferably, the end face of described sector unit described end face is dorsad that the decline that extends towards the described sector unit center of circle is domatic.
Preferably, described sector unit dorsad the fit bottom surface angle of described end face of the end face of described end face and described sector unit be 70 °.
Preferably, described sector unit and described wheel disc are structure as a whole.
Preferably, described sector unit is provided with the on-of pin matched with clutch.
The petrolic flywheel of the utility model, on the end face of wheel disc, the joint that is positioned at wheel disc and gear ring is evenly distributed with several sector units, thus the quality of flywheel can be increased, because the rotary inertia of flywheel is directly proportional to the quality of sector unit, the increase of sector unit quality result in the increase of Rotary Inertia of Flywheel.Again due to the increase of Rotary Inertia of Flywheel, in the middle of engine test monitor procedure, can find that engine speed fluctuations obviously reduces, there is not abnormal shake in motor.
Accompanying drawing explanation
The stereogram of the petrol engine flywheel that Fig. 1 provides for the utility model embodiment;
In Fig. 1, reference character is: 1 wheel disc, 1a end face, 2 gear rings, 3 sector units, 4 on-of pins.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
As shown in Figure 1, a kind of petrol engine flywheel, comprises wheel disc 1 and is arranged on the gear ring 2 on wheel disc 1 periphery, and on the end face 1a of wheel disc 1, the joint that is positioned at wheel disc 1 and gear ring 2 is evenly distributed with several sector units 3, and sector unit 3 is concentric with wheel disc 1.Guarantee that the quality of flywheel can not be overweight for the ease of arrangement, preferably, sector unit 3 is three, and the angle of the projection on end face 1a of the center of this sector unit 3 and the end face 1a line of centres is 120 °.Further preferably, the sector unit 3 dorsad end face of end face 1a and the perpendicular distance of end face 1a is 10mm, and namely the height of sector unit 3 is 10mm.The outside diameter of sector unit 3 is 274.4mm, and interior circular diameter is 245mm.According to rotary inertia formula: I=m*r
2; Wherein, I is the rotary inertia value of sector unit 3, and m is the quality of sector unit 3, and r is the turning radius of sector unit 3 around running shaft.From above formula, the increase of sector unit 3 quality result in the increase of Rotary Inertia of Flywheel.Again due to the increase of Rotary Inertia of Flywheel, in the middle of engine test monitor procedure, can find that engine speed fluctuations obviously reduces, there is not abnormal shake in motor.Flywheel in the present embodiment, only need increase by three pieces of outside diameters is 274.4mm, and interior circular diameter is 245mm, is highly the demand that the sector unit 3 of 10mm can meet rotary inertia.The rotary inertia that those skilled in the art can select the size of mass block to come needed for satisfied different flywheel according to the actual conditions of flywheel.
A kind of embodiment, preferably, the end face of sector unit 3 end face 1a is dorsad that the decline extended towards sector unit 3 center of circle is domatic.Further, preferably, sector unit 3 dorsad the fit bottom surface angle of end face 1a of the end face of end face 1a and sector unit 3 be 70 °.Because end face is domatic for declining, compared with being plane with end face, the both ends of the surface area on sector unit 3 between end face and bottom surface is less, structure like this, while increase rotary inertia, also can reduce the resistance of air that when flywheel rotates, sector unit 3 is subject to.Preferred 70 ° of angles in the present embodiment, those skilled in the art also can select other angle number of degrees according to the actual conditions of flywheel.
For the ease of manufacturing, sector unit 3 and wheel disc 1 are structure as a whole, and so, the mode by casting manufactures flywheel.For the ease of assembling with clutch, as shown in Figure 1, sector unit 3 is preferably provided with the on-of pin 4 matched with clutch.
In sum, content of the present utility model is not limited in the above-described embodiments, and those skilled in the art can propose other mode of execution easily according to guiding theory of the present utility model, and these mode of executions are all included within scope of the present utility model.
