Abstract
The utility model provides a counterbalance shaft of an engine, which comprises a shaft neck, wherein, a balance weight is connected with the middle part of the shaft neck, and chamfer angles are formed on the two side surfaces at one end of the balance weight, and the end provided with the chamfer angles is connected with the shaft neck. The counterbalance shaft of the engine can lead the counterbalance shaft to effectively reduce the caused noise and resistance during the rotating process, can better exert the performance of the engine, has simple structure, and can be widely applied to the engine of a motorcycle and a tricycle.
Description
Technical field
The utility model relates to a kind of trunnion shaft of motor, relates in particular to a kind of trunnion shaft that is used for tricycle and motorcycle engine.
Background technique
In the work cycle of motor, the movement velocity of piston is very fast, and speed is very inhomogeneous.Because piston is done high-speed straight-line motion repeatedly in cylinder, must on piston, wrist pin and connecting rod, produce very big inertial force.Except last bottom dead center position, various inertial force can not be made motor produce vibration by complete equilibrium.Motorcycle all adopts the better simply relatively uniaxiality balance of structure mechanism with the single-cylinder engine great majority, with balance single order reciprocal inertia force, to reach the purpose that reduces engine luggine.Yet, the present conventional balanced axle that exists on the market, the section of its equilibrium block rectangular mostly (as shown in Figure 1), the shortcoming of this design is can produce noise and resistance in the trunnion shaft rotary course, influences the performance of motor.
The model utility content
For solving the problems of the technologies described above, the utility model provides the balance shaft of engine of a kind of noise that can reduce to produce in the rotary course and resistance, thereby better brings into play the performance of motor.
Balance shaft of engine of the present utility model is achieved by following technical solution:
A kind of balance shaft of engine comprises axle journal, and the middle part of described axle journal is connected with equilibrium block, and described equilibrium block is provided with chamfering with the bi-side that described axle journal is connected an end.
In technique scheme, described equilibrium block is fan-shaped.
The utility model balance shaft of engine compared with prior art, its beneficial effect is as follows: the utility model balance shaft of engine, bi-side by an end that described equilibrium block is linked to each other with described axle journal are provided with chamfering, make trunnion shaft in rotary course, in balance single order reciprocal inertia force, because the design of chamfering diminishes the equilibrium block cross section, thereby its rotational resistance is diminished, afterwards in rotary course, reduce noise and the resistance that produces effectively, bring into play the performance of motor better, has simplicity of design, advantages such as reliable performance.
Description of drawings
Fig. 1 is the structural representation of available engine trunnion shaft;
Fig. 2 is the structural representation of the utility model balance shaft of engine;
Fig. 3 is the A-A sectional view of Fig. 2.
Embodiment
Below in conjunction with drawings and Examples the utility model balance shaft of engine is described further:
As shown in Figure 2, a kind of balance shaft of engine, it comprises axle journal 2, the middle part of described axle journal 2 is connected with equilibrium block 3, wherein, described axle journal 2 has ladder, be positioned at the both sides of described equilibrium block 3, be used for running in bearings 1 and gear assembly 4, link to each other with axle journal 2 bi-side of an end of described equilibrium block 3 are provided with chamfering 31, and the big I of described chamfering 31 is set according to the specification of trunnion shaft, and described chamfering 31 should guarantee to make equilibrium block 3 cross sections to diminish, so that the rotational resistance of equilibrium block 3 diminishes, thereby realize effectively reducing the noise that trunnion shaft produces and the effect of resistance in rotary course.By Fig. 3 further as can be known, described equilibrium block 3 is fan-shaped.The utility model balance shaft of engine has increased the design of chamfering, reduces the noise and the resistance that produce in rotary course effectively, thereby brings into play the performance of motor better.The utility model trunnion shaft can be widely used in motorcycle or tricycle engine.
The above-mentioned specific embodiment of the application only is that the utility model is made major electrical components.The those skilled in the art of technical field are under enlightenment of the present utility model under the utility model, and numerous variations or the combination that described specific embodiment is done or adopt similar fashion to substitute all do not exceed protection domain of the present utility model.
Claims (2)
1. a balance shaft of engine comprises axle journal, it is characterized in that, the middle part of described axle journal is connected with equilibrium block, and described equilibrium block is provided with chamfering with the bi-side that described axle journal is connected an end.
