Description
Technical field
This utility model relates to field of gears, particularly relates to a kind of silent gear.
Background technology
nullSince second industrial revolution，The application of machinery the most closely occupies whole manufacturing，Gear is then the important component part of operating between mechanical each parts，But gear on-stream generation noise is bigger，And in gear train，Difference according to mechanism，Noise can be divided into again acceleration noise and ring noise two kinds，On the one hand，When gear tooth engages，Make gear produce the biggest acceleration and surrounding medium disturbance can be caused due to impact，The acoustic radiation produced by this disturbance is referred to as the acceleration noise of gear，On the other hand，Under gear dynamic engagement force effect，Each parts of system can produce vibration，The produced acoustic radiation of these vibrations is referred to as ring noise，At present round gear noise aspect，Also there is a lot of improvement，As in Chinese Patent Application No. being: the patent of 201420227600.7 discloses one both sides in teeth are provided with fixture block and briquetting，Connected by elastic rod in the middle of fixture block and briquetting，Thus reduce by two gears in operation process，Teeth and teeth contact with each other the noise produced，But briquetting is installed and adds cost soon with card，And increase the fussy degree producing gear，During long-time use, briquetting also wears out serious with card soon again.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art, it is provided that a kind of method that can reduce the noise that gear produces in operation process.
This utility model is to be achieved through the following technical solutions:
A kind of silent gear, including gear, described gear outline is provided with teeth, being provided with teeth groove between adjacent teeth, described gear center offers axis hole, offers keyway on the inwall of axis hole and along the radial direction of gear, gear also includes elastomeric pad, offering straight hole equal-sized with elastomeric pad at teeth two side external surface, described elastomeric pad is embedded in the both sides straight hole of teeth, and elastomeric pad outer surface keeps concordant with teeth outer surface.
Further, described gear radially inwall offers oil storage tank cavity, and a teeth groove upper surface offers oil filler point wherein, and oil filler point connects with oil storage tank cavity, and oil filler point is provided above plug cock.
Further, described plug cock is equal with the diameter of oil filler point.
Further, described elastomeric pad uses organic polymer fiber to make, and offers multiple through hole on its surface.
Compared with prior art, the beneficial effects of the utility model are: this utility model novel structure, reasonable in design, it is provided by elastomeric pad, when two gears engage each other work, owing to teeth are provided with elastomeric pad, when teeth contact with teeth, elastomeric pad can play an effect resetted, the noise sent when can also reduce gear drive, has the effect of damping thus reduces the effect of noise.

Detailed description of the invention
In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with drawings and Examples, this utility model is further elaborated.Should be appreciated that specific embodiment described herein, only in order to explain this utility model, is not used to limit this utility model.
As depicted in figs. 1 and 2, a kind of silent gear that the present embodiment provides, including gear 3, described gear 3 outline is provided with teeth 1, is provided with teeth groove 2 between adjacent teeth 1, and described gear 3 center offers axis hole 5, keyway 6 is offered on the inwall of axis hole 5 and along the radial direction of gear 3, gear mass surface is covered with nickel coating, it is possible to reduce gear occurs situation about getting rusty during long-time use, thus extends its service life.
Described silent gear also includes elastomeric pad 10, straight hole equal-sized with elastomeric pad 10 is offered at 1 liang of side external surface of teeth, described elastomeric pad 10 is embedded in the both sides straight hole of teeth 1, and elastomeric pad 10 outer surface keeps concordant with teeth 1 outer surface, described gear 3 radially inwall offers oil storage tank cavity 4, teeth groove 2 upper surface offers oil filler point 8 wherein, oil filler point 8 connects with oil storage tank cavity 4, oil filler point 8 is provided above plug cock 7, and described plug cock 7 is equal with the diameter of oil filler point 8.
Described elastomeric pad 10 is made for organic polymer fiber, organic polymer fiber has the elastic and function of oil suction, when two gears engage each other work, owing to teeth 1 are provided with elastomeric pad 10, when two gear teeth 1 contact, elastomeric pad 10 can play an effect resetted, thus reduce the noise that two gears send in the running, also there is the effect of damping, and the oil absorptive function of elastomeric pad 10 makes it during gear operation, lubricating oil in oil storage tank cavity 4 is adsorbed with oneself by elastomeric pad 10, and flowed out by through hole 9, surface does not has lubricating oil to prevent teeth from occurring in operation process, and cause teeth 1 that abrasion occurs.
The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, all any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, within should be included in protection domain of the present utility model.
