Abstract
The utility model relates to a balance gear for a motorcycle engine, which comprises a main gear, an auxiliary gear, a shaft lining, main gear springs, auxiliary gear springs, a clamp ring, a flat washer and an elastic washer, wherein the main gear and the shaft lining is sleeved by the auxiliary gear are sequentially; main grooves of corresponding positions are arranged between the main gear and the shaft lining; the main gear springs are mounted in the main grooves; auxiliary grooves of corresponding positions are arranged between the auxiliary gear and the shaft lining; the auxiliary gear springs are mounted in the auxiliary grooves which are locked through the clamp ring; and the flat washer and the elastic washer are mounted on a shaft neck of the shaft lining between the clamp ring and the auxiliary gear. The utility model can effectively buffer the impact during the meshing of the gears, and reduce the noise generated by the meshing of the gears.
Description
Technical field
The utility model relates to a kind of gear driving pair of motorcycle engine variable working condition, particularly a kind of balance shaft gear that is applied to motorcycle engine.
Background technique
The piston of present motorcycle engine and connecting rod can produce powerful inertial force when high speed rotating, and this inertial force can pass to vehicle frame by motorcycle engine, thereby cause motorcycle vibration, cause noise simultaneously, energy consumption, coupling is loosening, influences such as overload, thereby greatly reduce the working life and the reliability of motorcycle engine, in order to alleviate the vibration of motorcycle engine, people adopt the trunnion shaft motorcycle engine at present, its principle is by increase suitable counterweight on the bent axle that the trunnion shaft actuation gear is installed, caused vibration when alleviating the bent axle high speed rotating, but owing to what transmit between trunnion shaft actuation gear and the balance shaft gear is the alternation active force, and exist the back lash when being meshing with each other, thereby cause producing knocking noise in the operation process, thereby be difficult to meet people's usage requirement.
Summary of the invention
In order to overcome the deficiencies in the prior art, the purpose of this utility model provides a kind of a kind of combined type balance gear that can reduce the knocking noise that trunnion shaft actuation gear and balance shaft gear produce in the operation process.
Technological scheme
The purpose of this utility model is achieved in that a kind of motorcycle engine balance tooth, comprise main tooth, secondary tooth, axle sleeve, main tooth spring, secondary tooth spring, snap ring, plain washer, elastic washer, its special way is: axle sleeve is made as second order boss seat, and second order boss seat upper end portion is provided with annular groove; Main tooth and secondary tooth are enclosed within respectively on the boss of second order boss seat of tooth internal axle sleeve, lock with snap ring again.
Described motorcycle engine balance tooth, its special way is: for making the balance tooth fastening, can set up plain washer or elastic washer between snap ring and secondary tooth.
Described motorcycle engine balance tooth, its special way is: be Spielpassung between axle sleeve and the main tooth.
Described motorcycle engine balance tooth, its special way is: be Spielpassung between axle sleeve and the secondary tooth.
Described motorcycle engine balance tooth, its special way is: be provided with the corresponding main groove in position between axle sleeve and the main tooth, adorn main tooth spring in the main groove.
Described motorcycle engine balance tooth, its special way is: be provided with the corresponding secondary groove in position between axle sleeve and the secondary tooth, adorn secondary tooth spring in the secondary groove.
Described motorcycle engine balance tooth, its special way is: main groove two or more, and main relatively tooth standard pitch circle center is centrosymmetric.
Described motorcycle engine balance tooth, its special way is: secondary groove is two or more, and secondary relatively tooth standard pitch circle center is centrosymmetric.
Beneficial effect:
Owing to adopted technological scheme described in the utility model: motorcycle engine balance tooth, the second order boss seat of axle sleeve cooperates with main tooth, secondary backlash respectively, and main tooth spring and secondary tooth spring are housed in the respective slot between axle sleeve and main tooth, the secondary tooth, the effective impact force in buffer gear cold when engagement effectively reduces the noise of gear engagement.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples.
Fig. 1 is the exploded view of the described motorcycle engine balance of the utility model embodiment tooth.
Embodiment:
Below in conjunction with accompanying drawing concrete structure of the present utility model is further described.
With reference to Fig. 1, be a kind of embodiment's of described motorcycle engine balance tooth exploded view, comprise axle sleeve 1, main tooth 2, secondary tooth 3, plain washer 4, elastic washer 5, card evil idea 6, main tooth spring 7, secondary tooth spring 8.Offer groove 11 on the axle sleeve 1, main tooth 2 is provided with and groove 11 position corresponding groove 21, and groove 11 is encircled into main groove with groove 21, the main tooth spring 7 of assembling in the main groove; Offer groove 12 on the axle sleeve 1, secondary tooth is provided with the through hole 31 consistent with groove 12, groove 12 and through hole 31 synthetic secondary grooves, the secondary tooth spring 8 of assembling in the secondary groove; The axle journal of axle sleeve 1 is provided with annular groove 13, main tooth 2, secondary tooth 3 are enclosed within on the axle sleeve 1 successively, main spring 7 is contained in the main groove, secondary tooth spring 8 is contained in the secondary groove, be enclosed within on the axle journal of axle sleeve 1 with a plain washer 4 again and seal secondary groove, drop out, on the axle journal of axle sleeve 1, be inserted in elastic washer 5 plain washers 4 more successively to prevent secondary tooth spring 8, load onto snap ring 6 in the last annular groove 13 on the axle journal of axle sleeve 1, make tight bunch of whole balance tooth assembly.
The above only is preferred embodiment of the present utility model, is not structure of the present utility model is done any pro forma restriction.All foundations technical spirit of the present utility model all still belongs in the scope of the technical solution of the utility model any simple modification, equivalent variations and modification that above embodiment did.
