Numerals 1, 2, 3, and 4 denote drive rotation bodies, drive idlers, transmission elements, and sliders, respectively, as in FIG.

In FIG. 2, the drive rotating body 1 may be fixed to the output shaft end (not shown) of the speed converting means (not shown) for shifting the rotational speed of the driving unit (not shown), as in the conventional apparatus. Is fixed to the output shaft end (not shown) of the drive unit directly without passing through the speed converting means. In addition, as in the conventional apparatus, a driving idler 2 is provided at a position separated from the driving rotor 1 by a predetermined distance, and the driving rotor 1 and the driving idler 2 of the driving rotor 1 are disposed. A transmission element 3 for converting the rotational movement into a linear movement is connected, and a slider 4 is attached to the transmission element 3.

However, unlike the conventional apparatus, in the apparatus according to the present invention, as shown in FIGS. 2 and 3, the slider 4 includes the first shifting rotor 5 and the second shifting rotor 6. Has its own speed converting means including a third speed change body (7), a fourth speed change body (8), a first speed change shaft (21), a second speed change shaft (22), and a slider case (27). have.

Here, the first variable speed rotating body 5 is rotated in accordance with the moving direction of the slider 4 and the outer side of the upper surface of the transmission element 3, the second speed rotating body 6 is Outside the inner surface of the lower side also rotates according to the moving direction of the slider (4). For example, as shown in FIG. 2, if the slider 4 moves to the right when the driving rotary body 1 rotates in the A direction, the first transmission rotary member 5 rotates in the B direction, and the driving rotation When the whole rotates in the reverse direction, the slider 4 moves to the left side, and the first variable speed rotating body 5 also rotates in the reverse direction.

The third shifting rotor 7 is fixed to the first shifting shaft 21 together with the first shifting rotor 5 to rotate at the same rotational speed as the first shifting rotor 5, and the fourth shifting rotor 5. 8 is fixed to the second transmission shaft 22 together with the second transmission rotating body 6 to rotate at the same rotational speed as the second transmission rotating body 6, and the third transmission rotating body 7 and the third Since the four shift rotor 8 is interlocked, the rotation speeds of the third shift rotor 7 and the fourth shift rotor 8 depend on the size or number of teeth of each other. Here, the third shifting body 7 and the fourth shifting body 8 may be in direct contact with each other, such as gears or frictional differences, and interlocked, and the winding transmission element 9 such as a belt, a chain, or a rope may be interlocked. It can also work by.

In addition, the above-mentioned first shift rotor 5, second shift rotor 6, third shift rotor 7, fourth shift rotor 8, and retractor transmission element 9 are all slider cases. It is contained in (27), and the 1st transmission shaft 21 and the 2nd transmission shaft 22 are supported by this slider case 27. As shown in FIG.

The slider 4 according to the present invention is preferably provided with a plurality of idle rollers 10 around the first speed rotating body 5 or around the second speed rotating body 6 to provide a transmission element 3. And the contact angle between the first variable speed rotating body 5 and the second speed variable rotating body 6 can be improved.

In addition, in FIG. 3, reference numerals 23 and 23 ′ denote bearings for supporting the rotation of the first transmission shaft 21, and 24 and 24 ′ are bearings for supporting the rotation of the second transmission shaft 22. , 25, 25 ', 26 and 26' respectively represent bearing covers for supporting these bearings.

When the ratio of the speed and the moving speed of the slider in the electric transmission device with a slider according to the present invention having the configuration as described above are obtained through the following equation.

When the moving speed of the transmission element 3 is V1, and the radius and rotation speed of the driving rotor 1 are R and ω, respectively, V1 is

Can be obtained by

That is, if the rotational direction of the drive rotary body is the A direction in FIG. 2, the transmission element 3 moves at the speed V1 in the lower side to the right and the upper side to the left.

In addition, the moving speed of the slider 4 is VS, and the rotating speed and radius of the first variable speed rotating body 5 are ω1, R1, and the rotating speed and radius of the second variable speed rotating body 6 are respectively ω2 and R2. If the slider 4 moves in the right direction as shown in Fig. 2, the moving speed V1 of the transmission element 3 and the moving speed VS of the slider 4

The relationship is established.

If the rotation speed and the radius of the third shifting body 7 are ω3 and R3, respectively, and the rotation speed and the radius of the fourth shifting body 8 are ω4 and R4, respectively, the third shifting rotor ( Between 7) and the fourth variable speed rotating body 8

If the speed ratio is 1 / n,

Since it can be expressed as follows, the speed ratio 1 / n

It can be seen that.

Here, when the radius R1 of the first transmission rotor 5 and the radius R2 of the second transmission rotor 6 are the same, equations (12) and (14) are respectively

Can be simplified.
