In order to achieve this goal, and also from a functional point of view, a power transmission device in which an input shaft and an output shaft are arranged on the same axis is often required. In that case, in the proposed power transmission device,
Although the input shaft and the output shaft are parallel to each other, they are not arranged on the same axis, so the above requirements cannot be met. In order to obtain an increase/deceleration ratio of about The problem was that the threaded part of the shaft was very large and became loose.

Since it is necessary to supply the balls 9 to the positions of the thread grooves 8 that are successively matched with each other, the balls 9 that have moved as the thread grooves 8 are moved must be brought into alignment with each other. The screws are circulated so as to be supplied to the positions of the eight screws. In that case, each rotation 1ql + 1.3
6 are arranged vertically, so the circulation groove 20 for circulating the balls 9 is as shown in FIGS. 2 and 3.

It is formed of a plate material of an appropriate thickness that is slidably inserted, and when the tip is pressed into contact with the ball 9, it forms a part of each of the storage cavities 13, 14, 15, and 16, so as to form a part of the corresponding storage cavity. 13, 14. and 15° 16 curvature, and is formed to be tapered approximately wedge-shaped.The ball position adjustment plate 12 is fixed to the case body 10 with screws 18 at the rear end of the ball position adjustment plate 12. The adjustment screw 19 that is threadedly inserted into the adjustment board 17 is formed with a screw (not shown) whose tip abuts and a screw (not shown). The ball position adjusting plate 12 is rotated to press the ball position adjusting plate 12 in the direction of the ball 9, or pulled back in the opposite direction to the ball 9 to hold the ball 9 at an appropriate position. It is something that

る。Therefore, for example, the first machine screw part 2 and the CF second machine screw part 5
If the first rotation shaft 1 is rotated as an input shaft with the pitch and pitch circle diameter of the first threaded part/I and the second threaded part 7 set to 6, then the screw ifl'+ Eight national territories are the first
The pitch between the rotating shaft 1 and the second rotating shaft 3 is 16, and if the first rotating shaft is rotated by 1, the second rotating shaft 3 will be rotated by 1!6 times. The pitch between the second rotating shaft 3 and the third rotating shaft lN16 is also 1G. 6 rotates 176 times. Therefore, when C1 first rotating shaft 1 is rotated once, the third rotation of the output shaft is 176 times.
/6 x 1/6, which means that the speed is reduced to 1/3G rotation. Conversely, if the third rotation ff1116 is removed from the input shaft, the first rotation shaft 1, which is the output shaft, will be accelerated by 36 times.Furthermore, if the second rotation 1III3 is removed from the input shaft, the first rotation shaft 1 will be The speed is increased six times, and the third rotary shaft 6 is decelerated 176 times and output to the same low level. Moreover, the first
If the rotary shaft 1 or the third rotary shaft 6 is used as the input shaft, the third rotary shaft 6 or the first rotary shaft 1, which is the output shaft with the highest acceleration/deceleration ratio, will be arranged on the same axis. Then, if the first rotating shaft is used as the input shaft, the second rotating shaft 3 will have 17
Sixth, the third rotary shaft 6 can simultaneously output at a speed reduction ratio of 1730 times, and the third rotary shaft 6 and the input shaft can simultaneously output at a speed increase ratio of 6 times and 36 times. I can do it.

速が可能になる。On the other hand, even if the high priest reduction ratio is 1/36 times or 36 times, the first machine screw part 4 and the second machine screw part 7 are different from the first machine screw part 2 and the second machine screw part 5. Since the diameter of the hole requires only 6 times as many holes, it is possible to form it in a very large size. In addition, in this case, regarding the pitch and the big circle diameter, the first large threaded part 4 and the second human threaded part 7 are multiplied by n, which is an integer, with respect to the first small threaded part 2 and the second small threaded part 5. Therefore, the lead angles of the screws 1148 are the same, and the resistance against the C ball 9 is completely 4", so slippage of the ball 9 can be eliminated, and reliable acceleration/deceleration can be achieved. It becomes possible.

In this case, each threaded portion 2, 4 . , 5.7 may be changed as appropriate. As mentioned above, if the rotation is not limited to +lq or 3 AC, but if the multi-stage arrangement or (previously) repeated arrangement of the rotating shafts is repeated as appropriate, an even larger increase/deceleration ratio can be obtained.

The third rotating shaft 6 is arranged so that its axis is parallel to the axis of the second rotating shaft 3 and on the same line as the axis of the first rotating shaft 1, and the small coincidence of the second rotating shaft 1113 is arranged. By bringing the screws 8 into contact with each other through the ball 9 and rotatably supporting them, when the first rotating shaft 1 is rotated once, the second rotating shaft 3 is decelerated to one fraction of the above-mentioned integer. At the same time, the third rotating shaft 6 is decelerated to 1/2 of the above-mentioned integer, but since the screw damage ε3 times and the lead angle are also the same, there is no resistance at all to the ball 9 at the lead angle. , the ball 9 is reliably decelerated without slipping at all.

On the other hand, if the third rotation tl'tll 6 is rotated once through the input shaft, the second rotation shaft 3 will be accelerated to iV + the integer number, and the first rotation shaft 1 will be accelerated to the integer number iV+. (The speed is increased to B. Furthermore, when the second rotating shaft 3 is moved to the input shaft, the first rotating shaft 1 is accelerated to the above-mentioned integer 8, and at the same time, the third rotating shaft 6 is accelerated to n. The speed is decelerated to one integer, making it possible to output simultaneous acceleration and deceleration.
Ru. In addition, by making the ratio of the pip and pitch diameters of each small screw part and large screw part the same, the first rotating shaft 1 and the third
Rotation@6 Since any axis can be arranged on the same line, it facilitates the installation when assembled into a machine and contributes to the simplification of the machine.

At the same time, by forming the supplied balls 9 so that they can be adjusted so as to be disposed on tangent lines of the directions of the respective screw portions, it is possible to reliably and smoothly increase/decelerate continuously. Adjustment eliminates backlash, so there is no error in forward and reverse rotation, and since no gears are used, there is no gear cutting process, and the structure itself is simple, so it can be provided at a very low cost.

In addition, it is compact in terms of drawing, and 1. It is capable of outputting simultaneous acceleration and deceleration, or simultaneous output at different ratios.Furthermore, since it uses gears and has 4 teeth, Since there are no two culms, it can be manufactured at low cost, and the input and output shafts can be arranged on the same line, so it does not take up much space when installed on various machines, etc., so it can be installed in any location. It has excellent effects such as:
