Abstract
The invention discloses a gear which comprises a gear normal plane, gear teeth, a shaft hole and toothed grooves. The gear teeth are uniformly distributed at the periphery of the gear normal plane. The shaft hole is used for mounting of a rotating shaft. The toothed grooves are formed between the gear teeth. A damping ring coats the peripheral surface of the shaft hole, and is filled with a damping material. Mounting grooves are formed in the outer end surface of the damping ring in the circumferential direction. Noise reduction acoustic panels are arranged in the mounting grooves. The damping ring arranged on the peripheral surface of the shaft hole is filled with the damping material, so that vibration generated in the rotation process of the gear can be reduced; and the noise reduction acoustic panels are arranged in the mounting grooves, so that noise generated in the rotation process of the gear is reduced. The gear is simple and reasonable in structure, and vibration and noise generated in the rotation of the gear can be reduced.

To abate the noise at present and these inevitable vibrations, the method being frequently used in enterprise is exactly to improve manufacture
Technique, improves Gear Processing precision, reduces alignment error etc., but which increases manufacturing cost, and difficulty is higher.
The content of the invention
In view of the shortcomings of the prior art, the technical problem to be solved in the present invention is to provide a kind of gear, rational in infrastructure,
With the function of reducing vibration and noise when rotating.
To achieve these goals, the present invention 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 position
Teeth groove between the gear teeth, shock ring is coated with the axis hole outer peripheral face, and vibration-absorptive material is filled with the shock ring,
The outer face of the shock ring is circumferentially with mounting groove, and noise-reducing acoustic board is provided with the mounting groove.
Further, the noise-reducing acoustic board includes that a layer plane sound-absorbing substrate and one layer of waveform sound panel are 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.
Beneficial effects of the present invention：
Gear of the invention, 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, mounting groove is circumferentially with the outer face of the shock ring, and noise-reducing acoustic board is provided with the mounting groove.In axis hole outer peripheral face
Vibration-absorptive material is filled with the shock ring of setting, it is possible to reduce vibration during pinion rotation, noise reduction sound-absorbing is set in mounting groove
Plate, reduces noise during pinion rotation.Gear structure of the invention is simple, rationally, vibration when can reduce pinion rotation and make an uproar
Sound.
