Abstract
The invention relates to the technical field of automobile gears, in particular to a noise reduction gear. The noise reduction gear comprises a shaft pillar, gear discs and gear bodies, the shaft pillar is arranged just between the gear discs, each gear body is arranged at the edge of the corresponding gear disc, a connecting tube is arranged between each gear disc and the shaft pillar, a fixing bolt is arranged in each connecting tube, the two gear discs are fixed in a parallel mode, a noise reduction cavity is formed between the gear discs, and the noise reduction cavity is in an oval shape and formed by the gear discs which correspond to each other vertically. According to the noise reduction gear, the noise reduction cavity is formed in the gear discs, the oval structure is adopted, the good noise reduction and attenuation effect is achieved, meanwhile, the butt joint mode is adopted, good installability and replaceability are achieved, and the noise reduction gear has the advantages of being convenient to use, easy to operate, good in practicability, low in cost and the like.
Description
Technical field
The present invention relates to automobile gear technical field, be specifically related to a kind of noise reduction gear.
Background technique
Gear is the colyliform mechanical parts of the engagement transmitting torque relying on tooth.Gear is by realizing changing rotating speed and moment of torsion, changing moving direction and change the functions such as forms of motion with other dentation mechanical parts (as another gear, tooth bar, worm screw).Due to advantages such as transmission efficiency are high, velocity ratio is accurate, power range is large, gear mechanism extensive use in industrial products, its design and manufaction level directly can have influence on the quality of industrial products.
Gear is main basic transmission element in automobile industry, and the quality of gear directly affects the noise of automobile, stationarity and working life.Automotive transmission is as the critical piece in car transmissions, for changing the torque and rotational speed of motor, starting to walk, accelerating, travelling and overcoming under the different conditions such as different kinds of roads obstacle to adapt to automobile to the different requirements driving net tractive force of wheel and the speed of a motor vehicle.Automotive transmission mainly relies on the velocity ratio of gear to change speed, complete in the interaction of often pair of mesh tooth face and relative movement in gear mechanism when motion and the transmission of power between working gear face, therefore gear is easy to produce wearing and tearing, particularly under high capacity and high speed, therefore can with very large sound when pinion rotation, produce noise pollution, even miscellaneous part is impacted.
Summary of the invention
The object of the invention is to the defect for prior art and deficiency, there is provided a kind of structure simple, a kind of noise reduction gear reasonable in design, easy to use, it adopts and be provided with silencing cavity in gear disk, and adopt ellipsoidal structure, there is good sound-deadening and noise-reducing effect, adopt docking mode simultaneously, there is good installability and convertibility, and it has easy to use, simple to operate, the features such as practicability is good, with low cost.
For achieving the above object, the technical solution used in the present invention is:
A kind of noise reduction gear of the present invention, comprise jack-post, gear disk and gear, described jack-post is arranged on gear disk middle, described gear is arranged on gear disk edge, is provided with connecting tube between described gear disk and jack-post, is provided with fixed bolt in described connecting tube, described gear disk is that double plate is parallel fixing, be provided with silencing cavity, described silencing cavity ovalize in the middle of described gear disk, formed by the upper and lower correspondence of gear disk.
Be provided with draw-in groove in described jack-post, described draw-in groove is arranged on connecting tube, and the setting of draw-in groove can ensure being connected and fixed of connecting tube, gear disk and jack-post, ensures that jack-post drives the rotation of whole gear disk.
Described gear two ends are provided with baffle plate, described baffle plate is welded on gear disk, and the design of baffle plate can formative gear connecting groove, can ensure that gear moves along groove, also prevent simultaneously and bring chain rupture when gear has breach, play certain provisional protection and urgent protective action; Baffle plate also can play the effect of water proof and dust proof simultaneously.
Be provided with acoustical cotton in described silencing cavity, acoustical cotton has good noise reduction sound absorption, greatly can reduce noise pollution, add erasure effect simultaneously.
After adopting said structure, beneficial effect of the present invention is: its employing of the present invention is provided with silencing cavity in gear disk, and adopts ellipsoidal structure, has good sound-deadening and noise-reducing effect, adopts docking mode simultaneously, have good installability and convertibility; Adopt the gear disk of dock, and up-down structure is consistent, has good assembling performance, adopts that the fixed bolt in connecting tube will both be fastening simultaneously, what ensure between the two is relatively fixing, and not affecting it normally uses, and improves easily manufactured, shortens engineering time; And it has easy to use, simple to operate, the features such as practicability is good, with low cost.
