Abstract
The utility model discloses a valve timing mechanism of a motorcycle engine. The valve timing mechanism of the motorcycle engine comprises a cam shaft (1) and a driven gear (2). An end neck of the cam shaft (1) penetrates into a shaft hole of the driven gear (2) and is connected with the driven gear (2) in an interference fit mode. The valve timing mechanism of the motorcycle engine has the advantages that manufacturing and installation are convenient, safety performance is high due to the fact that the interference fit of the hole and the shaft plays a role in transmitting moment of torsion and preventing axial moving, the number of elastic blocking rings is reduced, weight is lightened, and manufacturing cost is saved.
Description
Technical field
The utility model relates to a kind of motorcycle engine, particularly a kind of air distributing mechanism of engine for motorcycle.
Background technique
At present, existing air distributing mechanism of engine for motorcycle comprises camshaft and driven gear, after the axis hole of driven gear and the assembling of cam spindle end neck, adopt circlip to prevent axial jump at end face, simultaneously, and the timing pin by cam of camshaft end face penetrates in the end face groove of driven gear and is connected with driven gear, there is following deficiency in such structure: after adopting circlip to prevent that bearing from jumping, can't measuring gear and camshaft between the gap, after having the gap, the timing pin is when work, will bump with camshaft, security incident causes timing pin fracture, in case will occur the fracture of timing pin.
The model utility content
The purpose of this utility model just provides the high air distributing mechanism of engine for motorcycle of a kind of Safety performance.
The purpose of this utility model is to realize by such technological scheme, a kind of air distributing mechanism of engine for motorcycle, comprise camshaft and driven gear, the end neck of described camshaft penetrates in the axis hole of driven gear, and is connected by interference fit with driven gear.
Owing to adopted technique scheme, the utlity model has and make advantage easy for installation, adopt its interference fit by the hole axle to play transmitting torque and prevent the effect of axial jump, so that Safety performance is high, simultaneously, reduced circlip, alleviate weight, saved manufacture cost.
Description of drawings
Description of drawings of the present utility model is as follows:
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is described in further detail; but the utility model is not limited to these mode of executions; any on the present embodiment essence spirit improvement or substitute, still belong to the utility model claim scope required for protection.
Embodiment 1: as shown in Figure 1, a kind of air distributing mechanism of engine for motorcycle comprises camshaft 1 and driven gear 2, and the end neck of described camshaft 1 penetrates in the axis hole of driven gear 2, and is connected by interference fit with driven gear 2.
In the utility model, because camshaft 1 and driven gear 2 are connected by interference fit, the rotation of camshaft 1 directly drives driven gear 2 and rotates, come transmitting torque and prevent axial jump by this interference fit, simultaneously, the utility model has been cancelled circlip, has saved manufacture cost, has simplified installation.
Claims (1)
1. an air distributing mechanism of engine for motorcycle comprises camshaft (1) and driven gear (2), and it is characterized in that: the end neck of described camshaft (1) penetrates in the axis hole of driven gear (2), and is connected by interference fit with driven gear (2).
