Description
Technical field
The utility model belongs to field of mechanical technique, is related to a kind of flywheel, in more particularly to a kind of low noise gasoline engine
Flywheel.
Background technology
Flywheel is rotary inertia very big disk-shaped part, and it acts as an energy accumulator.For gasoline engine,
Piston stroke work done once, i.e. only expansion space stroke work done, and be vented, air inlet and compression three strokes will consume work(.Therefore
The torque that bent axle is externally exported is in cyclically-varying, and speed of crankshaft is also unstable.In order to improve this situation, in crankshaft rear end dress
Put flywheel.Therefore effect of the flywheel in gasoline engine is absorption and release mechanical energy, and the torque balance for exporting bent axle is uniform.
The flywheel commonly used on current gasoline engine includes being shaped as discoidal flywheel body, is arranged on flywheel body front end face
On blade, be arranged on the reinforcement, balancing weight and pole core in flywheel body backside face.With the development of the society, people couple
The quality requirement more and more higher of environment, therefore the demand of the gasoline engine of low noise constantly lifts, and in flywheel exactly gasoline engine
One of important component for producing noise.Therefore the structure of flywheel is improved particularly important.
The content of the invention
There is provided a kind of rotation noise is low for the above-mentioned problems in the prior art for the purpose of this utility model
Flywheel in gasoline engine.
The purpose of this utility model can be realized by following technical proposal：A kind of flywheel in low noise gasoline engine, bag
Include to offer in the middle part of discoidal flywheel body, flywheel body and several are further opened with axis hole, flywheel body around axis hole week
To several equally distributed mounting holes, the front of described flywheel body is provided with counterweight base and several blades, and it is special
Levy and be, described several blades are divided equally in the both sides of counterweight base, and blade is shaped as arc shape, described flywheel
The branching block that several tear drop shapes are uniformly distributed with atrium, the bottom surface of the atrium is offered on the back side of body,
Offer an open slot on the periphery wall of described flywheel body, and cave inward some are offered on described open slot
Cored pedestal, described iron core pedestal are set positioned at the corresponding position of open slot on bar runner, the front of the flywheel
One end extend at two of which leaf position, and be integrally connected with two blades.
In flywheel in a kind of above-mentioned low noise gasoline engine, the middle part of the flywheel body has around the periphery of axis hole
To the hole pedestal that the front and back of flywheel body is raised.The structural strength for the flywheel that the design of this structure can make is bigger, installs
It is more firm.
In flywheel in a kind of above-mentioned low noise gasoline engine, the sidepiece of described hole pedestal offers a U-shaped and opened
Mouthful.When flywheel is in rotation process, the air-flow at the susceptor edges of hole can be bypassed out of U-shaped opening, so as to offset a part of gas
The noise of stream.
In flywheel in a kind of above-mentioned low noise gasoline engine, described hole pedestal and the junction of flywheel body are circle
Angle transition.
In flywheel in a kind of above-mentioned low noise gasoline engine, each corner of described branching block is set using fillet
Meter, and the junction of branching block and flywheel body is also round-corner transition.
In flywheel in a kind of above-mentioned low noise gasoline engine, described blade, counterweight base and the equal position of iron core pedestal
In same level.
Compared with prior art, being provided with the flywheel in this low noise gasoline engine will produce during flywheel turns
The tear drop shape branching block and runner in air-flow shunting so that its noise it is lower.

Embodiment
The following is specific embodiment of the utility model and with reference to accompanying drawing, further is made to the technical solution of the utility model
Description, but the utility model is not limited to these embodiments.
As shown in Figure 1 and Figure 2, the flywheel in this low noise gasoline engine includes discoidal flywheel body 1, flywheel body 1
Middle part, which is offered, is further opened with several around the circumferential equally distributed mounting hole 3 of axis hole 2, flywheel sheet in axis hole 2, flywheel body 1
The front of body 1 is provided with counterweight base 4 and several blades 5, and several blades 5 are divided equally in the both sides of counterweight base 4, and leaf
Being shaped as on arc shape, the back side of flywheel body 1 offering of piece 5 is uniformly distributed with atrium 6, the bottom surface of atrium 6
An open slot 8 is offered on the branching block 7 of several tear drop shapes, the periphery wall of flywheel body 1, and is offered on open slot 8
Cored pedestal 10, iron core base are set positioned at the corresponding position of open slot 8 on the runner 9 caved inward, the front of flywheel
One end of seat 10 is extended at the position of two of which blade 5, and is connected with two one of blade 5, and the middle part of flywheel body 1 is around axle
