Description
Technical field
The utility model is related to a kind of gear, is related to transmission device technical field.
Background technology
Gear is common mechanical transmission part, and it has important effect in mechanical field.In the market most
Number gear is in transmission process, and due to the effect of many factors and driving force, it can produce vibration and rub and produce noise, this
The physical and mental health and the working life of gear of the worker in its working range are had a strong impact on.
To abate the noise at present and these inevitably vibrate, the method usually used in enterprise is exactly to improve manufacture
Technique, improves Gear Processing precision, reduces alignment error etc., but so adds manufacturing cost, and difficulty is higher.
Utility model content
In view of the deficienciess of the prior art, the technical problems to be solved in the utility model is to provide a kind of gear, structure
Rationally, the function of vibration and noise when being rotated with reduction.
To achieve these goals, the utility model is to realize by the following technical solutions：
A kind of gear, including gear normal plane, uniformly it is laid in the gear teeth around gear normal plane, the axis hole for installing rotating shaft
And the teeth groove between the gear teeth, shock ring is coated with the axis hole outer peripheral face, damping material is filled with the shock ring
Material, is circumferentially with mounting groove, the mounting groove in the outer face of the shock ring and is provided with noise-reducing acoustic board.
Further, the noise-reducing acoustic board includes a layer plane sound-absorbing substrate and one layer of waveform sound panel is constituted, institute
State plane sound-absorbing substrate to be made up of glass fibre cotton, the sound panel be bonded with the surface recombination of the plane sound-absorbing substrate,
The sound panel is formed by vermiculite granule compacting.
Further, the vibration-absorptive material is rubber.
Further, the glass fibre cotton is nano-grade glass fibre cotton.
The beneficial effects of the utility model：
Gear of the present utility model, including gear normal plane, the uniform gear teeth being laid in around gear normal plane, turn for installing
The axis hole of axle and the teeth groove between the gear teeth, shock ring is coated with the axis hole outer peripheral face, is filled in the shock ring
There is vibration-absorptive material, be circumferentially with the outer face of the shock ring in mounting groove, the mounting groove and be provided with noise-reducing acoustic board.In axle
Vibration-absorptive material is filled with the shock ring that hole outer peripheral face is set, it is possible to reduce vibration during pinion rotation, is set in mounting groove
Noise-reducing acoustic board, noise during reduction pinion rotation.Gear structure of the present utility model is simple, reasonable, can reduce pinion rotation
When vibration and noise.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is the structural representation of noise-reducing acoustic board of the present utility model.
Embodiment
To be easy to understand technological means, creation characteristic, reached purpose and effect of the utility model realization, below
With reference to embodiment, the utility model is expanded on further.
Referring to Fig. 1,2, the utility model provides a kind of technical scheme：A kind of gear, including gear normal plane 1, uniform cloth
The gear teeth 2 around gear normal plane 1, the axis hole 3 for installing rotating shaft and the teeth groove between the gear teeth 2, in the axis hole 3
Outer peripheral face is coated with shock ring 4, and vibration-absorptive material is filled with the shock ring, is circumferentially with the outer face of the shock ring
Noise-reducing acoustic board 6 is provided with mounting groove 5, the mounting groove.Set in axis hole outer peripheral face and damping is filled with shock ring, shock ring
Material, gear produces certain vibration when rotated, and vibration-absorptive material can reduce vibration, sets and installs in the outer face of shock ring
Groove, sets mounting groove to save steel.Noise-reducing acoustic board is set in mounting groove, and noise-reducing acoustic board is used to eliminate pinion rotation
The noise of generation.Gear structure of the present utility model is simple, reasonable, it is possible to reduce vibration and noise during rotation.
As the further improvement of above-mentioned technical proposal, the noise-reducing acoustic board 6 includes the He of a layer plane sound-absorbing substrate 61
One layer of sound panel 62 is constituted, and the plane sound-absorbing substrate 61 is made up of glass fibre cotton, in the table of the plane sound-absorbing substrate 61
Face compound sticking has sound panel 62, and the sound panel 62 is formed by vermiculite granule compacting.Glass fibre cotton is sprayed on plane sound-absorbing
On the surface of substrate 61.Noise-reducing acoustic board is made up of plane sound-absorbing substrate and sound panel, dual sound-absorbing, and noise-reduction effect is more
It is good.Glass fibre cotton uses nano-grade glass fibre cotton.
As the further improvement of above-mentioned technical proposal, the vibration-absorptive material of filling is rubber in shock ring.The existing height of rubber
Play state has high glutinous state again, and the elasticity of rubber is produced by the change of its coiled molecule conformation, rubber molecule interphase interaction meeting
The motion of strand is hindered, stickiness feature is shown again, thus with good damping, sound insulation and shock-absorbing capacity.
General principle of the present utility model and principal character and advantage of the present utility model has been shown and described above, for
For those skilled in the art, it is clear that the utility model is not limited to the details of above-mentioned one exemplary embodiment, and without departing substantially from this
