Abstract
The invention relates to the technical field of the gears and in particular a rubber noise reduction gear. The rubber noise reduction gear comprises a gear and gear teeth; the gear teeth are arranged on the gear; lugs are arranged on the two sides of the gear teeth; first rubber layers are arranged in the internal grooves of the lugs; a central block is arranged in the gear; second rubber layers are arranged on the two sides of the central block; a groove is formed in the central block; limiting blocks are arranged on the second rubber layers and embedded in the groove; cover plates are arranged on the outer sides of the second rubber layers; the lugs and the gear teeth are made of the same material. The rubber noise reduction gear has the advantages that the rubber layers are embedded in the gear teeth to effective reduce noise generated by engagement of gears, and the rubber layers also are additionally arranged inside the gear to reduce noise generated by vibration of the gear, and therefore, the purpose of noise reduction is achieved and an excellent using effect can be produced.
Description
Technical field
The present invention relates to gear technique field, especially a kind of rubber Noise-reducing gear.
Background technique
Gear is extensive in application in machine equipments, owing to all can produce noise in the occlusion process between the vibrations of gear its gear when work itself and gear, will embody the excessive situation of noise, be unfavorable for production in the region stricter to noise requirements.
Summary of the invention
The deficiency that during in order to overcome existing working gear, its noise is excessive, the invention provides a kind of rubber Noise-reducing gear.
The technical solution adopted for the present invention to solve the technical problems is: a kind of rubber Noise-reducing gear, comprise gear and wheel tooth, described gear is provided with wheel tooth, the both sides of described wheel tooth are provided with projection, rubber layer one is provided with in the inner groovy of described projection, be provided with central block in described gear, described central block both sides are provided with rubber layer two.
According to another embodiment of the invention, comprise further, described central block is provided with groove, and described rubber layer two is provided with limiting stopper, and described limiting stopper embeds in groove.
According to another embodiment of the invention, comprise further, outside described rubber layer two, be provided with cover plate.
According to another embodiment of the invention, comprise further, described projection is consistent with the material of wheel tooth.
The invention has the beneficial effects as follows, this rubber Noise-reducing gear embeds rubber layer on its wheel tooth, rubber layer effectively reduces the noise produced when being engaged between gear with gear, too increase rubber layer at gear internal simultaneously, this reduces the noise that gear vibrations itself produce, get to the object of noise reduction, using effect is good.
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 gear tooth configuration schematic diagram of the present invention.
Fig. 3 is gear structure schematic diagram of the present invention.
In figure 1, gear, 2, wheel tooth, 3, projection, 4, rubber layer one, 5, central block, 6, groove, 7, rubber layer two, 8, cover plate.
Embodiment
If Fig. 1 is structural representation of the present invention, a kind of rubber Noise-reducing gear, comprise gear 1 and wheel tooth 2, described gear 1 is provided with wheel tooth 2, the both sides of described wheel tooth 2 are provided with projection 3, be provided with rubber layer 1 in the inner groovy of described projection 3, be provided with central block 5 in described gear 1, described central block 5 both sides are provided with rubber layer 27.
According to another embodiment of the invention, comprise further, described central block 5 is provided with groove 6, and described rubber layer 27 is provided with limiting stopper 8, and described limiting stopper 8 embeds in groove 6.
According to another embodiment of the invention, comprise further, outside described rubber layer 27, be provided with cover plate 8.
According to another embodiment of the invention, comprise further, described projection 3 is consistent with the material of wheel tooth 2.
This rubber Noise-reducing gear increases the projection 3 of one group of dislocation on its wheel tooth 2, when engaging between gear with gear, rubber layer 1 between projection 3 plays transition absorbing vibration and absorbs noise, effectively reduce noise result, increase by one group of rubber layer 27 in its both sides of central block 5 of gear 1 inside simultaneously, the noise that gear 1 vibrations itself produce can be carried out noise reduction process by rubber layer 27, and make it meet Production requirement, using effect is good.
