ている。However, NIN is the target roll number N0UT of the conical wheel (2), the rotation speed R1 of the carrier a1 is the radius R2 from the rotation axis (1) to point A, and the rotation axis (
1) The radius r1 from the 0 point is the radius r2 from the η axis of the steel ball (8) to the point A. The radius r2 is the radius from the η axis of the steel ball (8) to the 0 point.The operation will be explained next. When power is not being transmitted to the input shaft (1) from the drive source (not shown), the second
As shown in the figure, the carrier (8
) is input shaft +1) Ill! Being pressed against l,
The steel ball (8) is in contact with the four-part groove 110a) at its deepest point.

の深い方向に移動し、接触が離されることになる。The axial thrust of the contact point B due to the co-rotating force overcomes the elastic force of the leaf spring 0 frame and moves the carrier OQ and the output shaft (9) fixed thereto to the side opposite to the input shaft. In this case the fifth
As shown in the figure, the carrier OI is a stopper w, +18a)
The steel ball (8) will move along the inclined surface of the four-part groove (10a). At this time, the depth l of the four-part groove (]Oa) is deeper than the moving distance l' of the output shaft (9), so one ball (8) will not come off the four-part groove (10a). . At the same time, the power of the drive source is transmitted with torque through the contact points A and B%C that are pressed against the steel ball (8) mentioned above, and is decelerated by the planetary motion of the steel ball (8) to the output shaft (9). Power can be transmitted. In addition, when the rotation direction of the drive source is reversed, the steel ball (8) is inserted into the four-part groove (10a).
The contact will move deeper and the contact will be released.

に戻ることになる。Even if the rotation is reversed in this way, the inclination angle θ is provided only on one side, so if the steel ball (8) is placed on the side opposite to the inclination angle,
Even if they make contact, the angle of contact is large, and there is no wedge-like wedge-shaped wedge-like action, which results in a one-way clutch function that only causes the carrier to scream and the steel ball (8) to spin idly. Then, the axial thrust due to the rotational force disappears, and the carrier OQ (output shaft (9)) returns to its original position as shown in FIG. 1 due to the elastic force of the leaf spring (T).

る。The force acting on the steel ball (8) is a balance of forces at eight points, and the pressing according to the rotational force is a force, and the minimum pressing necessary for friction transmission is the generation of force. The gear ratio can be arbitrarily selected by simply changing the positions of the eight contact points, resulting in a wide range of gear ratios. Note that even if the input and output shafts are reversed, the gear ratio will simply be a reciprocal, but by making the input shaft movable in the axial direction by spline connection or the like, the same operation and function can be achieved.

In addition, the conical wheel, fixed plate, and carrier are all rotating shafts, and two human-powered shafts and one
It is also possible to obtain a device with an output shaft or one human-powered shaft with two output shafts.
