正に保つことができる。2. Description of the Related Art FIG. 3 shows an example of a conventionally known belt transmission device. The belt transmission device of this example is mainly applied to a device having a short distance L between the pulley axes, and the belt 3 wound around the driving pulley 1 and the driven pulley 2 is rotatable around the tip of the lever 4. The tension roller 5 attached to the belt 3 is pressed to keep the tension of the belt 3 proper. The base end of the lever 4 is
It is rotatably attached to the frame 6 and the belt 3
If plastic elongation occurs in the belt 3, the tension of the belt 3 can be appropriately maintained by rotating the lever 4 in the direction of the arrow A accordingly.

プーリを原動機ごと移動し、プーリ軸間距離Lを大きく
するといった調整方法が通常とられている。In a belt transmission having a long distance L between pulley shafts, a large lever 4 must be provided because the amount of plastic elongation of the belt 3 becomes enormous. Therefore, it is difficult to design in terms of space and strength. Therefore, it is difficult to provide a tension adjusting device including the lever 4 and the tension roller 5. Therefore, an adjusting method is usually adopted in which the prime mover is moved together with the prime mover according to the plastic elongation of the belt 3 to increase the distance L between the pulley axes.

Not only is it difficult to apply to a belt transmission having a long distance between pulley shafts, but it is also not preferable from the viewpoint of reducing power transmission efficiency and shortening the belt life. On the other hand, the adjustment method such as moving the prime mover together with the prime mover to increase the distance between the pulley axes requires moving a heavy moving body against the tension of the belt, and after moving the belt, it becomes Since the squareness of the pulley shaft must be adjusted precisely, it is difficult to apply it to the actual machine.

Another object of the present invention is to provide a winding transmission device with a tension adjusting device that can easily and highly accurately adjust the distance between pulley shafts without reducing the power transmission efficiency and the belt life.

The power transmission efficiency is not reduced and the life of the power transmission member is not adversely affected, and the invention can be applied to a winding transmission device having a large inter-wheel distance. Further, one end of the turning member is rotatably attached to the output shaft of the prime mover, and the center shaft of the driving wheel is rotatably attached to the other end of the turning member, and the first gear provided on the output shaft of the prime mover and the When meshed with the second gear provided on the center axis of the driving wheel, the second gear revolves around the first gear when the turning member turns about the output shaft of the prime mover. Therefore, the first and second
The meshing state of the gears is always kept constant regardless of the turning position of the turning member, and the power of the prime mover can be transmitted to the driven wheels via the driving wheel and the power transmission member, and at the same time as the rotation surface of the belt. The squareness with the central axis of the driving wheel is always kept constant, and the squareness adjustment after driving the turning member becomes unnecessary. Therefore, the tension of the power transmission member can be adjusted simply by operating the biasing member such as the turnbuckle, so that the tension of the power transmission member can be adjusted very easily.

It revolves around the first gear 16 fixed to the output shaft 13 of the prime mover. Therefore, the first and second gears 16, 17
The meshed state is always kept constant regardless of the turning position of the turning member 14, and the power of the prime mover 12 can be transmitted to the driven pulley 2 via the drive pulley 1 and the belt 3. Further, since the squareness between the belt rotating surface and the driving pulley shaft 15 is always kept constant, it becomes unnecessary to adjust the squareness after driving the turning member.
