置に関する。BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a device for adjusting the tension of a steel belt in a power transmission mechanism using a steel belt that transmits rotational driving force such as a robot without backlash.

のプーリーの軸間距離を変えるもの等がある。[Prior Art] Conventionally, means for adjusting the tension of a steel belt include changing the winding angle of the steel belt around a pulley, and installing another pulley between two pulleys whose position can be adjusted in a direction perpendicular to the belt. There are some that change the distance between the axes of the two pulleys.

を図３および図４を参照しながら説明する。As an example, a device equipped with a tension adjustment pulley will be described with reference to FIGS. 3 and 4.

なっている。As shown in the figure, a drive pulley 9 is fixed to the drive shaft, a driven pulley 10 is fixed to the driven shaft, and a steel belt 11 transmitting leftward rotation between the drive pulley 9 and the driven pulley 10, and a right A steel belt 12 that transmits directional rotation is stretched. The tension adjustment pulley 13 is rotatably attached to the shaft 14 by a bearing 15, and the position of the shaft 14 can be changed in a direction perpendicular to the belt 11 by a tension adjustment bolt 16.

置を調整し、左回転伝達ベルト１１を張ることによって
右回転伝達ベルト１２を張ることができる。The reason why two steel belts 11 and 12 are used here is to widen the range of rotational motion. By adjusting the position of the tension adjustment pulley 13 using the tension adjustment bolt 16 and tensioning the left rotation transmission belt 11, the right rotation transmission belt 12 can be tensioned.

用いる場合には装置の軽量化の点で問題となる。また、
部品点数も多くなってしまう。[Problems to be Solved by the Invention] However, in the above-described configuration, since the position of the left rotation transmission belt 11 in contact with the tension adjustment pulley 13 changes, the left rotation transmission belt 11 has a curvature of the tension adjustment pulley 13. Bending causes repeated stress. Therefore, in order to keep the repeated stress applied to the left rotation transmission belt 11 within the fatigue limit, it is necessary to make the diameter of the tension adjustment pulley 13 as large as that of the drive pulley 9 and the driven pulley 10. When used in robots, etc., there is a problem in reducing the weight of the device. Also,
The number of parts also increases.

構が必要となり、部品点数が多くなる。[0007] In addition, in other conventional methods of changing the amount of belt wrapping around the pulley, it is necessary to separate one of the driving pulley and the driven pulley into upper and lower parts and to have a mechanism for twisting the upper and lower pulleys, which increases the number of parts. .

A fixed steel belt, a first cylinder arranged in contact with the front or back side of the steel belt, and the first cylinder is in contact with the steel belt through the steel belt, and the steel belt is arranged around half a circumference or more. The second cylinder is in contact with the second cylinder via a steel belt, and the distance between the third cylinder and the first cylinder is adjusted in the opposite direction to the first cylinder. It is equipped with a bolt.

Therefore, the diameter of the cylinder can be reduced. In addition, the tension of the steel belt can be adjusted with a simple configuration of only three cylinders and adjustment bolts.
