Abstract
The invention discloses a noise elimination gear which comprises a gear body, and further comprises elastic gaskets, wherein gear teeth are arranged on the outer profile of the gear body; tooth grooves are formed between the adjacent gear teeth; a shaft hole is formed in the center of the gear body; a keyway is formed in the inner wall of the shaft hole in the radial direction of the gear body; straight holes with the same size as the elastic gaskets are formed in the outer surfaces of the two sides of the gear teeth; the elastic gaskets are embedded in the straight holes in the two sides of the gear teeth; and the outer surfaces of the elastic gaskets are flush with the outer surfaces of the gear teeth. According to the noise elimination gear, the structure is novel, the design is reasonable, and the elastic gaskets are arranged on the gear teeth, so that when two gears are mutually meshed for operation, and when the gear teeth are in contact with each other, the elastic gaskets can exert a reset function, the nose generated during gear transmission can be reduced, the vibration damping function is achieved, and the noise reduction effect is achieved.
Description
Technical field
The present invention relates to field of gears, particularly relate to a kind of silent gear.
Background technology
nullSince second industrial revolution，The application of machinery 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 very big acceleration and surrounding medium disturbance can be caused due to impact，The acoustic radiation produced by this disturbance is called 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 called ring noise，At present round gear noise aspect，Also there is a lot of improvement，As in Chinese Patent Application No. being: a kind of disclosed in the patent of 201420227600.7 be provided with fixture block and briquetting by both sides in teeth，Connected by elastic rod in the middle of fixture block and briquetting，Thus reducing 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，In long-time use procedure, briquetting also wears out serious with card soon again.
Summary of the invention
The invention aims 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.
The present invention is 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 and oil storage tank cavity connect, and oil filler point is provided above plug cock.
Further, described plug cock is equal with the diameter of oil filler point.
Further, described elastic pressuring plate adopts organic polymer fiber to make, and offers multiple through hole on its surface.
Compared with prior art, the invention has the beneficial effects as follows: present configuration is novel, reasonable in design, it is provided by elastomeric pad, when two gears engage each other work, owing to teeth are provided with elastic pressuring plate, when teeth contact with teeth, elastic pressuring plate can play an effect resetted, the noise sent when can also reduce gear drive, has the effect of damping thus reducing the effect of noise.

Detailed description of the invention
In order to make the purpose of the present invention, technical scheme and advantage clearly understand, below in conjunction with drawings and Examples, the present invention is further elaborated.Should be appreciated that specific embodiment described herein is only in order to explain the present invention, is not intended to limit the present invention.
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 situation about getting rusty occurs in long-time use procedure in gear, thus extending 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 and oil storage tank cavity 4 connect, 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 elastic and oil suction function, when two gears engage each other work, owing to teeth 1 are provided with elastic pressuring plate 10, when two gear teeth 1 contact, elastic pressuring plate 10 can play an effect resetted, thus reducing 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 in gear operation process, with lubricating oil in oil storage tank cavity 4 is adsorbed on certainly by elastomeric pad 10, and flowed out by through hole 9, surface does not have lubricating oil to prevent teeth from occurring in operation process, and cause that abrasion occur in teeth 1.
The foregoing is only presently preferred embodiments of the present invention, not in order to limit the present invention, all any amendment, equivalent replacement and improvement etc. made within the spirit and principles in the present invention, should be included within protection scope of the present invention.
