いる。 As shown in Figure 1, a conventional transmission using a friction wheel moves the friction wheel A left and right on the radius line of the disk B, but a large force is required to move the friction wheel, and the movement is slow. The speed of the friction wheel cannot be increased, and the wear of the friction wheel is large. If you try to solve these problems, Figure 2
As shown in the figure, the friction wheel C is steered and shifted left and right at an angle to change gears, but the power transmission to the friction wheel C and the steering device are complicated, and there are problems with high speed rotation and durability. , these are the reasons why the practicality is low.

のないころがりのみによるものである。 This invention is intended to solve these drawbacks. To explain this with reference to an embodiment, as shown in FIG. When the speed change operation plate 6 is moved in the H direction, the moving friction wheel 3
When the axis J-J' of the movable friction wheel 3 moves H away from the axis G-G' of 2 and 4 as shown in FIG. 4, the movable friction wheel 3 moves in the H direction via the bearing 7. axis J
-J′ and the angles E and D are created with respect to the friction wheels 2 and 4,
The movable friction wheel 3, which generates a force to move in the direction of arrow S, is guided by an elongated hole with an angle K on the speed change operation plate 6, and begins to move in the direction of arrow F, as angles E and D become smaller. , when reaching the axes G-G' of the friction wheels 2 and 4, the angles E and D become 0 degrees, no force is generated in the direction of arrow S, and it stops at point P. Obtain the desired gear ratio M:L. In this case, Deceleration and speed increase are performed by moving the speed change operation plate 6 in the opposite direction to H. In this case, the contact between the friction wheels is only by rolling without slipping.

機構であればよい。 The angle K of the elongated hole in the speed change operation plate 6 depends on the purpose of the speed change operation, and if the speed is changed little by little, the angle K
by increasing the distance of movement of the speed change operation plate 6,
The elongated hole angle K of the operating plate 6 can be any desired guide mechanism such as an elongated hole or a groove, and the elongated hole angle K can be determined according to the purpose of use.

The shape of the elongated hole can be selected according to the characteristics of the purpose of use, and since the relationship between the movement position of the speed change operation plate 6 and the gear ratio is accurately grasped, the desired speed change ratio can be determined based on the movement position of the speed change operation plate 6. be able to.
