Description
Technical field
This utility model relates to automobile gear technical field, is specifically related to a kind of noise reduction gear.
Background technology
Gear is dependent on the colyliform machine components of the engagement transmission moment of torsion of tooth.Gear is by realizing changing rotating speed and moment of torsion, the change direction of motion and changing the functions such as forms of motion with other dentation machine components (such as another gear, tooth bar, worm screw).Due to the advantages such as transmission efficiency is high, gear ratio is accurate, power bracket is big, gear mechanism extensive use in industrial products, its design and manufacture level can directly influence 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 service life.Automotive transmission is as the critical piece in car transmissions, for changing torque and the rotating speed of electromotor, with adapt to automobile in starting, accelerate, travel and overcome under the different conditions such as different kinds of roads obstacle the different requirements driving net tractive force of wheel and speed.Automotive transmission relies primarily on the gear ratio of gear to change speed, in gear mechanism, the interaction of every pair of mesh tooth face and relative motion complete when motion and the transmission of power between working gear face, therefore gear is easy to produce abrasion, particularly under high capacity and high speed, therefore can the very big sound of band when pinion rotation, produce noise pollution, even miscellaneous part is impacted.
Utility model content
The purpose of this utility model is in that the defect for prior art and deficiency, thering is provided a kind of simple in construction, a kind of noise reduction gear reasonable in design, easy to use, it adopts and is provided with silencing cavity in toothed disc, 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 practicality is good, with low cost.
For achieving the above object, the technical solution adopted in the utility model is:
A kind of noise reduction gear described in the utility model, including jack-post, toothed disc and gear, described jack-post is arranged on toothed disc middle, described gear is arranged on toothed disc edge, is provided with connecting tube, is provided with gim peg in described connecting tube between described toothed disc and jack-post, described toothed disc is that double plate is parallel fixing, it is provided with silencing cavity, described silencing cavity ovalize in the middle of described toothed disc, toothed disc correspondence up and down forms.
Being provided with draw-in groove in described jack-post, described draw-in groove is arranged in connecting tube, and the setting of draw-in groove ensure that the connection of connecting tube, toothed disc and jack-post is fixed, it is ensured that jack-post drives the rotation of whole toothed disc.
Described gear two ends are provided with baffle plate; described baffle plate is welded on toothed disc, baffle plate be designed to formed gear link slot, it is possible to ensure gear move along groove; also prevent simultaneously and bring chain rupture when gear has breach, play certain provisional protection and urgent protective effect；Baffle plate also is able to play the effect of water proof and dust proof simultaneously.
Being provided with acoustical cotton in described silencing cavity, acoustical cotton has good noise reduction sound absorption, it is possible to be substantially reduced noise pollution, adds erasure effect simultaneously.
After adopting said structure, this utility model has the beneficial effect that its employing of this utility model is provided with silencing cavity in toothed disc, and adopts ellipsoidal structure, has good sound-deadening and noise-reducing effect, adopt docking mode simultaneously, there is good installability and convertibility；Adopt the toothed disc of dock, and up-down structure is consistent, has good assembleability, adopt the gim peg in connecting tube both to be fastened, it is ensured that being relatively fixed between the two simultaneously, do not affect it and normally use, improve easily manufactured, shorten maintenance time；And it has easy to use, simple to operate, the features such as practicality is good, with low cost.
