Abstract

The utility model relates to the technical field of engines, in particular to a balance helical gear structure of a VBF engine. The structure comprises a balance shaft assembly and a buffering balance shock-absorbing device arranged on the balance shaft assembly. The balance shaft assembly is provided with a limiting stop block, the buffering balance shock-absorbing device comprises a sealing check ring, a buffering body, a balance shaft driven gear and a shock-absorbing block, the sealing check ring and the buffering body are arranged on the balance shaft assembly, the buffering body is fixed to the balance shaft assembly through a key, the sealing check ring is disposed between the limiting stop block and the buffering body, a groove used for fixing the balance shaft driven gear is formed in the position, close to the sealing check ring, of the buffering body, and the shock-absorbing block is disposed between the balance shaft driven gear and the buffering body. The structure has the advantages of being simple in structure, reasonable in design, low in manufacturing cost and the like, the principle that a helical gear can lower noise is mainly used, and the problem that the engine generates noise in the operation process is solved.

Description

A kind of VBF engine balance oblique gear mechanism
Technical field
The utility model relates to technical field of engines, particularly a kind of VBF engine balance oblique gear mechanism.
Background technique
What current existing motorcycle engine adopted is whole straight-tooth balanced controls, its structure as shown in Figure 1, it is in engine operation process, owing to there is no damping device, engine noise is difficult to control, when accelerating or slowing down, engine vibration alters a great deal, and the working life of motor, Safety performance are existed to potential safety hazard.
Model utility content
The purpose of this utility model is for the defect of prior art and deficiency, and VBF engine balance oblique gear mechanism a kind of simple in structure, reasonable in design, increasing service life of engine is provided.
For achieving the above object, the technical solution adopted in the utility model is: a kind of VBF engine balance oblique gear mechanism described in the utility model, comprise balance shaft module and be arranged on the cushioning balance damping device on balance shaft module, described balance shaft module is provided with positive stop, cushioning balance damping device comprises Sealing shield ring, buffer body, balance shaft driven gear wheel and snubber block, Sealing shield ring and buffer body are arranged on balance shaft module, described buffer body is fixed on balance shaft module by key, Sealing shield ring is arranged between positive stop and buffer body, position near Sealing shield ring on described buffer body is provided with the groove for stable equilibrium axle driven gear, snubber block is arranged between balance shaft driven gear wheel and buffer body.
Further, described positive stop and balance shaft module integrated setting.
Adopt after said structure, the utility model beneficial effect is: a kind of VBF engine balance oblique gear mechanism described in the utility model, comprise balance shaft module and be arranged on the cushioning balance damping device on balance shaft module, described balance shaft module is provided with positive stop, cushioning balance damping device comprises Sealing shield ring, buffer body, balance shaft driven gear wheel and snubber block, Sealing shield ring and buffer body are arranged on balance shaft module, described buffer body is fixed on balance shaft module by key, Sealing shield ring is arranged between positive stop and buffer body, position near Sealing shield ring on described buffer body is provided with the groove for stable equilibrium axle driven gear, snubber block is arranged between balance shaft driven gear wheel and buffer body.In use, motor, in the process of running, due to piston up-down, converts crankshaft rotating motion to, in the process of work, due to inertia, whole motor easily produces vibrations, after having increased bumper and absorbing shock Equilibrator, in motor using process, the working condition of motor improves, and reduces engine vibration frequency, reaches the working life that extends motor.The utlity model has simple in structure, reasonable in design, the advantage such as fabricating cost is low.
Accompanying drawing explanation
Accompanying drawing described herein is to be used to provide further understanding of the present utility model, forms the application's a part, but does not form to improper restriction of the present utility model, in the accompanying drawings:
Fig. 1 is the structural representation of prior art;
Fig. 2 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing and specific embodiment, describe the utility model in detail, illustrative examples wherein and explanation are only used for explaining the utility model, but not as to restriction of the present utility model.
As shown in Figure 2, a kind of VBF engine balance oblique gear mechanism described in the utility model, comprise balance shaft module 1 and be arranged on the cushioning balance damping device on balance shaft module 1, described balance shaft module 1 is provided with positive stop 2, cushioning balance damping device comprises Sealing shield ring 3, buffer body 4, balance shaft driven gear wheel 5 and snubber block 6, Sealing shield ring 3 and buffer body 4 are arranged on balance shaft module 1, described buffer body 4 is fixed on balance shaft module 1 by key 7, Sealing shield ring 3 is arranged between positive stop 2 and buffer body 4, position near Sealing shield ring 3 on described buffer body 4 is provided with the groove 8 for stable equilibrium axle driven gear 5, snubber block 6 is arranged between balance shaft driven gear wheel 5 and buffer body 4.
It should be noted that described positive stop 2 and balance shaft module 1 integrated setting.
In use, motor, in the process of running, due to piston up-down, converts crankshaft rotating motion to, in the process of work, due to inertia, whole motor easily produces vibrations, after having increased bumper and absorbing shock Equilibrator, in motor using process, the working condition of motor improves, and reduces engine vibration frequency, reaches the working life that extends motor.The utlity model has simple in structure, reasonable in design, the advantage such as fabricating cost is low.
More than show and described basic principle of the present utility model and major character and advantage of the present utility model.The technician of the industry should understand; the utility model is not restricted to the described embodiments; that in above-described embodiment and specification, describes just illustrates principle of the present utility model; do not departing under the prerequisite of the utility model spirit and scope; the utility model also has various changes and modifications, and these changes and improvements all fall within the scope of claimed the utility model.The claimed scope of the utility model is defined by appending claims and equivalent thereof.
