Detailed Description
The present invention will be described in detail with reference to the accompanying drawings 1-2 and the detailed description thereof.
Referring to fig. 1 and fig. 2, the present embodiment provides an installation tool for a tension belt, which is applied to a wheel train structure, where the wheel train structure includes a driving wheel 1, a driven wheel 2 and a tension belt 3, and the tension belt 3 is respectively sleeved on the driving wheel 1 and the driven wheel 2. The installation tool for the tensioning belt comprises a cylindrical table 4 and a fixing bolt 5, wherein threaded holes 6 are formed in the cylindrical table 4 at intervals, and the threaded holes 6 are matched with the fixing bolt 5. The diameter of the cylindrical table 4 is gradually reduced from one end to the other end, and a limiting boss 7 is arranged at the end side with the small diameter of the cylindrical table 4. The limiting boss 7 is used for being clamped between the tensioning belt 3 and the driving wheel 1 or the driven wheel 2, and the cylindrical table 4 is fixed on the driving wheel 1 or the driven wheel 2 through the fixing bolt 5 and the limiting boss 7.
The installation process of the installation tool of the tension belt comprises the following steps: referring to fig. 1 specifically, firstly, the inner side of the limit boss 7 is clamped on the driving wheel 1, as shown in the figure, at the position where the top end of the driving wheel 1 is intersected with the tensioning belt 3, the fixing bolt 5 passes through the cylindrical table 4 and then abuts against the driving wheel 1, at this time, the fixing bolt 5 and the limit boss 7 are arranged in an acute angle and act on the cylindrical table 4 together, and the cylindrical table 4 is clamped on the driving wheel 1 similarly to the chopstick principle; then, the tensioning belt 3 is firstly fixed in a wheel groove of the driven wheel 2 and then wound on the outer side surface of the cylindrical table 4, at the moment, the limiting boss 7 is clamped between the tensioning belt 3 and the driving wheel 1, finally, the driving wheel 1 is rotated by using a wrench or other methods, so that the cylindrical table 4, the tensioning belt 3 and the driving wheel 1 rotate simultaneously, the tensioning belt 3 slowly slides into the wheel groove of the driving wheel 1 from the outer side surface of the cylindrical table 4, and finally, the cylindrical table 4 reaches the position where the bottom end of the driving wheel 1 is intersected with the tensioning belt 3, and the installation of the tensioning belt 3 is completed.
The installation process of the installation tool of the tension belt of the invention can also be as follows: firstly, clamping the inner side of a limiting boss 7 on a driven wheel 2, pushing a fixing bolt 5 to the driven wheel 2 after the fixing bolt 5 passes through a cylindrical table 4 at the position where the top end of the driven wheel 2 is intersected with a tensioning belt 3, and at the moment, arranging the fixing bolt 5 and the limiting boss 7 in an acute angle and acting on the cylindrical table 4 together, wherein the cylindrical table 4 is clamped on the driven wheel 2 similar to a chopstick principle; then, the tensioning belt 3 is firstly fixed in a wheel groove of the driving wheel 1 and then wound on the outer side surface of the cylindrical table 4, the limiting boss 7 is clamped between the tensioning belt 3 and the driven wheel 2, finally, the driven wheel 2 is rotated by using a wrench or other methods, so that the cylindrical table 4, the tensioning belt 3 and the driven wheel 2 rotate simultaneously, the tensioning belt 3 slowly slides into the wheel groove of the driven wheel 2 from the outer side surface of the cylindrical table 4, finally, the cylindrical table 4 reaches the position where the bottom end of the driven wheel 2 is intersected with the tensioning belt 3, and the installation of the tensioning belt 3 is completed.
According to the installation tool for the tension belt, the cylindrical table 4 is clamped between the tension belt 3 and the driving wheel 1 or the driven wheel 2 through the limiting boss 7 and is fixed on the driving wheel 1 or the driven wheel 2 through the fixing bolt 5 and the limiting boss 7, so that the accurate installation of the tension belt 3 is realized in the process that the cylindrical table 4 rotates along with the driving wheel 1 or the driven wheel 2, the installation tool is simple and efficient, and the production time is saved. The limit boss 7 functions to smoothly feed the tension belt 3 into the pulley groove. The diameter of the cylindrical table 4 is gradually reduced from one end to the other end, and the limiting boss 7 is arranged at the end, with the smaller diameter, of the cylindrical table 4, so that the limiting boss 7 is obliquely arranged towards the wheel groove direction of the driving wheel 1 or the driven wheel 2, and the tensioning belt 3 can smoothly slide into the wheel groove of the driving wheel 1 or the driven wheel 2.
As one of the preferred embodiments, three screw holes 6 are provided. Three screw hole 6 sets up along the radial direction interval of cylindric lock 4, makes cylindric lock 4 can be fixed in action wheel 1 more steadily on, has also prevented the inhomogeneous problem that leads to the life-span of cylindric lock 4 atress short.
In one preferred embodiment of the present invention, the drive pulley 1 is a crankshaft. The wheel train structure of the engine is basically that a crankshaft is set as a driving wheel to drive other driven wheels to rotate.
In one preferred embodiment of the present invention, the driven wheel 2 is a water pump or an air conditioner. Because the water pump and the air conditioner occupy large space and have insufficient space for installing and placing the automatic tensioner or the manual tensioner, the installation tool of the invention is suitable for installing the tensioning belt 3 between the driving wheel 1 and the driven wheel 2.
Although the invention has been described in detail above with reference to specific embodiments, it will be apparent to one skilled in the art that modifications or improvements may be made based on the invention. Accordingly, such modifications and improvements are intended to be within the scope of the invention as claimed.
