Abstract
The utility model discloses a balance shaft gear for a gasoline engine. The balance shaft gear comprises a main gear body and a sub gear body, wherein the sub gear body is arranged on the main gear body in a matched way, the main gear body comprises a center shaft post, the sub gear body is matched with the center shaft post, a buffer layer is arranged between the sub gear body and the center shaft post, a plurality of grooves are correspondingly arranged on the main gear boxy and the sub gear body, and elastic elements are arranged in the grooves. Through the adoption of the mode, the balance shaft gear for the gasoline engine has the advantage that the noise and the abrasion of the gear in the operation process can be reduced.
Description
Technical field
The utility model relates to the mechanical gear field, particularly relates to a kind of petrol engine balance shaft gear.
Background technique
Because piston and the connecting rod of present petrol engine can produce powerful inertial force when High Rotation Speed, and this inertial force can pass to machine by petrol engine, thereby cause machine vibration, can cause noise simultaneously, energy consumes, coupling is loosening, the impacts such as overload, thereby greatly lowered the life and reliability of petrol engine, in order to alleviate the vibration of petrol engine, the present common balance axle of people petrol engine, its principle is by increasing suitable counterweight at the bent axle that the trunnion shaft actuation gear is installed, caused vibration when alleviating the crankshaft high-speed rotation, but because what transmit between trunnion shaft actuation gear and the balance shaft gear is the alternation active force, and exist the back lash when it is intermeshing, thereby cause producing knocking noise in the operation process, thereby be difficult to meet people's usage requirement.Along with the raising to the petrol engine usage requirement, be necessary balancing-shaft gear structure is improved.
The model utility content
The technical problem that the utility model mainly solves provides a kind of petrol engine balance shaft gear, can reduce noise and the wearing and tearing of gear in running.
For solving the problems of the technologies described above, the technological scheme that the utility model adopts is: a kind of petrol engine balance shaft gear is provided, comprise: master gear body and pinion body, described pinion body is equipped with on the master gear body, described master gear body comprises central column, and described pinion body matches with central column, is provided with buffer layer between described pinion body and the central column, correspondence is provided with a plurality of grooves on described master gear body and the pinion body, is provided with elastic component in the described groove.
In preferred embodiment of the utility model, described groove evenly distributes around master gear body and pinion body center.
In preferred embodiment of the utility model, described elastic component is spring.
In preferred embodiment of the utility model, described buffer layer is damping rubber layer or resin layer.
In preferred embodiment of the utility model, described master gear body and pinion body are made by steel.
The beneficial effects of the utility model are: the utility model petrol engine can reduce noise and the wearing and tearing of gear in running with balance shaft gear.
Description of drawings
Fig. 1 is the structural representation that the utility model petrol engine is used balance shaft gear one preferred embodiment;
The mark of each parts is as follows in the accompanying drawing: 1, master gear body, 2, the pinion body, 3, central column, 4, buffer layer, 5, elastic component.
Embodiment
Below in conjunction with accompanying drawing preferred embodiment of the present utility model is described in detail, thereby so that advantage of the present utility model and feature can be easier to be it will be appreciated by those skilled in the art that protection domain of the present utility model is made more explicit defining.
See also Fig. 1, a kind of petrol engine balance shaft gear, comprise: master gear body 1 and pinion body 2, described pinion body 2 is equipped with on master gear body 1, described master gear body 1 comprises central column 3, and described pinion body 2 matches with central column 3, is provided with buffer layer 4 between described pinion body 2 and the central column 3, correspondence is provided with a plurality of grooves on described master gear body 1 and the pinion body 2, is provided with elastic component 5 in the described groove.
In addition, described groove evenly distributes around master gear body 1 and pinion body 2 centers.
In addition, described elastic component 5 is spring, and spring can reduce the noise between master gear body 1 and the pinion body 2, also can the shock absorbing load.
In addition, described buffer layer 4 is damping rubber layer or resin layer, and the damping rubber that is bonded on the gear has damping function to the vibration of gear, and can effectively absorb meshed transmission gear is the vibration that produces, and the propagation of vibration is played damping function.
In addition, described master gear body 1 and pinion body 2 are made by steel, and steel have preferably physical property, and intensity is high, long service life.
The utility model petrol engine balance shaft gear arranges first buffer layer 4 on central column 3, then pinion body 2 is equipped with on master gear body 1, with the groove alignment of pinion body 2 and master gear body 1, and elastic component 5 is set in groove, finishes installation.
Be different from prior art, the utility model petrol engine can reduce noise and the wearing and tearing of gear in running with balance shaft gear.
The above only is embodiment of the present utility model; be not so limit claim of the present utility model; every equivalent structure or equivalent flow process conversion that utilizes the utility model specification and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present utility model.
