Abstract
The utility model discloses a kind of noise reducing type output sprocket wheel of motorcycle engine, including output chain gear body, the output chain gear body outer surface is coated with buffer layer, the output chain gear body central is provided with splined hole vertically, output chain gear body is axially respectively arranged at two ends with the annular boss dorsad extended, and the inwall of the annular boss is inclined plane.The utility model can effectively reduce motorcycle, and chain produces noise with output chain gear during being engaged in the process of running, lifts cornering ability.
Description
Technical field
The utility model is related to engine mounting parts field, more particularly to a kind of noise reducing type motorcycle engine output chain
Wheel.
Background technology
Output chain gear is one of main building block of motorcycle engine, is mainly used in transfer motion power.In the prior art,
Due to the limitation of output chain gear material itself, motorcycle in the process of running, chain and output chain gear during being engaged easily
Noise is produced, normal driving is influenceed.
Utility model content
In view of this, the purpose of this utility model is to provide a kind of noise reducing type output sprocket wheel of motorcycle engine, can be effective
Chain produces noise to reduction motorcycle with output chain gear during being engaged in the process of running, lifts cornering ability.
Noise reducing type output sprocket wheel of motorcycle engine of the present utility model, including output chain gear body, the output chain gear
Body outer surface is coated with buffer layer, and the output chain gear body central is provided with splined hole, output chain gear body axial direction vertically
The annular boss dorsad extended is respectively arranged at two ends with, the inwall of the annular boss is inclined plane.
Further, the thickness of the buffer layer is 4~5mm.
Further, the buffer layer uses thermoplastic elastomer (TPE).
Further, two annular boss are symmetrical.
Further, the annular boss and this body by integral forming of output chain gear.
Further, the angle α between the annular boss inclined plane and output chain gear body axial end be 120~
150°。
Further, the output chain gear body is made of alloy structure Steel material.
The beneficial effects of the utility model are：Noise reducing type output sprocket wheel of motorcycle engine of the present utility model, by setting
Buffer layer is put, makes chain with output chain gear body during being engaged, the carrier bar of chain is in contact with buffer layer first, buffer layer
The noise produced between the two by impact can be effectively absorbed, the effect of noise reduction is reached, cornering ability is lifted, and engine turns
Speed is higher, and load is bigger, and because the noise of impact generation is bigger during operation, the noise reduction effect of this output chain gear body is more obvious；
By setting splined hole and annular boss, and the inwall of annular boss is inclined plane, is not only convenient for being assembled with output shaft, is filled
With simplicity, and bonding strength can be improved, enhancing structure stability lifts engine performance.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model；
Fig. 2 for Fig. 1 A-A to sectional view；
Fig. 3 is the utility model use state schematic diagram.
Embodiment
As shown in Figure 1 to Figure 3：The noise reducing type output sprocket wheel of motorcycle engine of the present embodiment, including output chain gear body
1, the outer surface of output chain gear body 1 is coated with buffer layer 2, by setting buffer layer, chain is existed with output chain gear body
During occlusion, the carrier bar of chain is in contact with buffer layer first, and buffer layer can effectively absorb to be produced because of impact between the two
Noise, reach the effect of noise reduction；The output chain gear body 1 is centrally along splined hole 3 is axially arranged with, for being carried out with output shaft
Assembling；Output chain gear body 1 is axially respectively arranged at two ends with the annular boss 4 dorsad extended, and the inwall of the annular boss 4 is to incline
Inclined-plane 4a, is not only convenient for being assembled with output shaft, and assembling is easy, and can improve bonding strength, enhancing structure stability,
Lift engine performance.
In the present embodiment, the thickness of the buffer layer 2 is 4~5mm, makes it have enough noise reductions, is ensureing drop
Performance of making an uproar adds service life while good.
In the present embodiment, the buffer layer 2 uses thermoplastic elastomer (TPE), not only with high resiliency, ageing-resistant, oil resistivity etc.
Excellent properties, and it is easy to processing and fabricating, low cost.
In the present embodiment, two annular boss 4 symmetrically, the company with output shaft can be strengthened by setting annular boss 4
Intensity and support strength are connect, overall performance is improved.
In the present embodiment, the annular boss 4 is integrally formed with output chain gear body 1, can not only lift output chain gear
The bulk strength of body 1, and be easy to be assembled with output shaft, it is also convenient for processing and manufacturing.
In the present embodiment, the angle α between the inclined plane 4a of annular boss 4 and the axial end of output chain gear body 1 is
120~150 °, angle α between the inclined plane 4a and the axial end of output chain gear body 1 of the present embodiment is 135 °, be easy to it is defeated
Shaft is dismounted and fixed, and improves assembling convenience.
In the present embodiment, the output chain gear body 1 is made of alloy structure Steel material, the output chain gear of the present embodiment
Body 1 uses structural alloy steel 20CrMo, can not only lift the intensity of output chain gear body 1, and make it have higher
Quenching degree, no temper brittleness, weldability is good, and the tendency for forming cold cracking is small, and machinability and cold strain plasticity are good, service life
It is long.
Finally illustrate, above example is only unrestricted to illustrate the technical solution of the utility model, although ginseng
The utility model is described in detail according to preferred embodiment, it will be understood by those within the art that, can be to this
The technical scheme of utility model is modified or equivalent, without departing from the objective and model of technical solutions of the utility model
Enclose, it all should cover among right of the present utility model.
