Specific implementation mode
With reference to the accompanying drawings and examples, the present invention is further explained.In the following detailed description, only pass through explanation
Mode describes certain exemplary embodiments of the present invention.Undoubtedly, those skilled in the art will recognize,
In the case of without departing from the spirit and scope of the present invention, described embodiment can be repaiied with a variety of different modes
Just.Therefore, attached drawing and description are regarded as illustrative in nature, and are not intended to limit the scope of the claims.
As depicted in figs. 1 and 2, the tensioner sprocket wheel of adaptive chain drive, including pedestal 1, the both sides difference of the pedestal 1
Two holders 2 being oppositely arranged are installed, correspondence is equipped with wheel shaft 3 on two holders 2, and axis is slidably fitted on the wheel shaft 3
4 are held, tensioner sprocket wheel 5 is installed on the bearing 4, the both sides of the bearing 4 are respectively arranged with bearing mobile space, may be implemented
Bearing mobile space is set as x, the wheel shaft 3 by axial movement of the bearing 4 on the wheel shaft 3 in the present embodiment
Compressed spring 6 is set between the bearing 4 and the holder 2, the outer diameter of the compressed spring 6 is less than the tensioner chain
The internal diameter of wheel 5.
Spring push plate 7 is set on the wheel shaft 3 between the bearing 4 and the compressed spring 6, the spring pushes away
The outer diameter of plate 7 is less than the internal diameter of the tensioner sprocket wheel 5.Acting force of the spring is acted on the spring push plate 7 by the compressed spring 6
On, the then spring push plate 7 pushes the bearing 4, the spring push plate 7 can be as the protection board of the bearing 4, can
The bearing 4 is damaged with preventing the compressed spring 6 to be applied directly on the bearing 4,4 service life of the bearing is caused to become
It is short, in addition, the acting force of the spring of the compressed spring 6 can be integrally distributed on the bearing 4 by the spring push plate 7 so that
The active force being applied on the bearing 4 is uniform, is not in be caused since certain point stress is excessive outside bearing inner race and bearing
The phenomenon that dislocation damage of circle.
