Part forms.
Compared with prior art, the utility model has the beneficial effects that：The utility model is simple in structure, by the gear teeth with it is soft
Property gear between noise abatement chamber reduce automobile gear noise for generating in engagement, and flexible gear is filled with and nibbles in engagement
Sideshake is closed, contacts the friction of generation when further reduced noise, while decreasing engagement between the gear teeth and other gear teeth, also
The vibrations generated when having the shoe cream room snubber block that both sides are arranged up and down also to alleviate engagement well, indirectly reduce noise,
In addition the lubrication heat dissipation channel opened up inside connection strap has also achieved the purpose that heat dissipation well, while also extending making for gear
Use the service life.

Specific implementation mode
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
The every other embodiment obtained, shall fall within the protection scope of the present invention.
- 3 are please referred to Fig.1, a kind of embodiment provided by the utility model：A kind of low-noise automobile gear, including gear sheet
The periphery of body 1, reinforcing rib 2, the gear teeth 5, shoe cream room 6 and connection strap 8, gear 1 is uniformly provided with the gear teeth 5, and the side of the gear teeth 5 is set
Flexible gear 12, and noise abatement chamber 11 is offered between the gear teeth 5 and flexible gear 12, it reduces automobile gear and is generated in engagement
Noise, the peak of flexible gear 12 is less than the peak of gear 5, and flexible gear 12 is made of elastic material, and
Flexible gear 12 is filled with meshing backlass when engagement, further reduced noise, and the center of gear 1 offers axis connection hole
7, the bottom of the gear teeth 5 is connected with the lateral wall of reinforcing rib 2, and tooth socket 10 is offered between adjacent gear 5, reinforcing rib 2 it is interior
Side wall is fixedly connected with the lateral wall of shoe cream room 6, and oil filler point 3 is offered on shoe cream room 6, and shoe cream room 6 is internally provided with oil storing tube
