Abstract

The invention relates to the technical field of gears, particularly to a baffle plate type noise reduction gear. The baffle plate type noise reduction gear comprises a gear body and a gear shaft; the gear body is arranged on the gear shaft; each side of the gear body is provided with a baffle plate which is provided with a through hole; the through holes sleeve the gear shaft which is provided with a tightening nut; the inner side of each baffle plate is provided with a silencing layer; each side of the gear body is provided with a stopping block; the center of each stopping block is provided with a cushion block. According to the baffle plate type noise reduction gear, one baffle plate is added between every two gears, the silencing layer is added between each baffle plate and the corresponding gear, and accordingly the noise produced during operation between the gears is effectively adsorbed, the noise during the gear operation is reduced, and the production requirements are met.

Description

Baffle-type Noise-reducing gear
Technical field
The present invention relates to gear technique field, especially a kind of baffle-type Noise-reducing gear.
Background technique
Gear is extensive in application in machine equipments, but gear in use, because engagement is that friction can produce noise between itself vibrations and mechanical parts, needs there is certain requirement to noise sometimes, and this is just unfavorable for producing.
Summary of the invention
In order to overcome the large deficiency of existing gear noise, the invention provides a kind of baffle-type Noise-reducing gear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of baffle-type Noise-reducing gear, comprise gear and gear shaft, described gear is arranged on gear shaft, described gear both sides are provided with baffle plate, described baffle plate is provided with through hole, described through hole is enclosed within gear shaft, and described gear shaft is provided with tightening nut, and on described baffle plate, inner side is provided with noise reduction layer.
According to another embodiment of the invention, comprise further, described gear both sides are provided with block.
According to another embodiment of the invention, comprise further, the central position of described block is provided with cushion block.
The invention has the beneficial effects as follows, this baffle-type Noise-reducing gear increases by one group of baffle plate between gear, adds noise reduction layer between baffle plate and gear, effectively the noise absorption produced when running between gear is fallen, reduce noise when gear runs, meet Production requirement.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the present invention is further described.
Fig. 1 is structural representation of the present invention.
Fig. 2 is scheme of installation of the present invention.
In figure 1, gear, 2, through hole, 3, gear shaft, 4, tightening nut, 5, baffle plate, 6, block, 7, cushion block, 8, noise reduction layer.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of baffle-type Noise-reducing gear, comprise gear 1 and gear shaft 3, described gear 1 is arranged on gear shaft 3, described gear 1 both sides are provided with baffle plate 5, and described baffle plate 5 is provided with through hole 2, and described through hole 2 is enclosed within gear shaft 3, described gear shaft 3 is provided with tightening nut 4, and on described baffle plate 5, inner side is provided with noise reduction layer 8.
According to another embodiment of the invention, comprise further, described gear 1 both sides are provided with block 6.
According to another embodiment of the invention, comprise further, the central position of described block 5 is provided with cushion block 7.
This baffle-type Noise-reducing gear is at the gear shaft 3 upper cover overhead gage 5 of its gear 1; block 6 is processed at the inner circle of gear 1; cushion block 7 is processed in the through hole of baffle plate 5; cushion block 7 is contacted with block 6; by baffle plate 5 extrusion-deformation when being placed on turn tightening nut 4, also protecting the safety of gear, add noise reduction layer 8 in the inner side of baffle plate 5; improve the effect of noise reduction, using effect is good.
