Embodiment
The embodiment of the present invention is described further below in conjunction with the accompanying drawings.
Following examples are only to illustrate example of the present invention to be clear, and not to the limit of embodiments of the present invention
It is fixed.For those of ordinary skill in the field, it is various forms of that other can also be made on the basis of the following description
Change changes, and these belong to protection of the spiritual obvious changes or variations drawn of the invention still in the present invention
Among scope.
As shown in Figures 1 to 3, a kind of crawler belt Chain tensioner, including take-up pulley 1, tension axle 2, copper sheathing 3, the take-up pulley 1
Including body 11 and wheel rim 12, the body 11 is split type setting with wheel rim 12, and the annular wheel rim 12 is socketed in described
The outer ring of body 11 and for interference fit；The tension stage casing of axle 2 couples with the inner ring spline of the body 11, the tension axle 2
Both ends shaft part is rotatablely connected with axle sleeve type bearing 4, and the endoporus of bearing 4, which is inlayed fixed copper sheathing 3 and rotated with the tension axle 2, matches somebody with somebody
Close.
