DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a variable speed motor,
In particular, the present invention relates to a novel improvement for mechanically changing the speed of an operation of a pachinko tulip or the like by causing an output shaft rotating at a reduced speed to rotate at a variable speed.

[0002]

2. Description of the Related Art A motor of this type, which has been conventionally used, is generally not shown, but simply reduces the speed of a constant-speed motor by gear reduction and uses it as rotation of an output shaft. And the like, such as opening and closing or rotating.

[0003]

Since the conventional motor is configured as described above, there are the following problems. That is, since the movement of the pachinko tulips and the like is produced by the constant speed motor, the movement is regular and constant, which is not suitable in view of the playability of the pachinko and the like.

SUMMARY OF THE INVENTION The present invention has been made to solve the above problems, and in particular, mechanically fluctuates the operation of a pachinko tulip or the like by rotating a decelerated rotating output shaft at a variable speed. It is an object to provide a variable speed motor as described above.

[0005]

A variable speed motor according to the present invention comprises: a flat rotating body provided on a rotating shaft of the motor;
A first support shaft provided on the rotating body and eccentric to the rotation shaft, a planetary gear provided on the first support shaft and meshing with a ring-shaped internal tooth, and a second supporter eccentrically provided on the planetary gear. A spindle, a coupling body having an engagement notch engaged with the second spindle, and an output shaft provided in the coupling body and concentric with the rotation shaft; The transmission is transmitted to the output shaft via two support shafts and a coupling body.

[0006]

In the variable speed motor according to the present invention, the planetary gear and the rotating shaft of the motor are eccentrically coupled to each other, and the output shaft and the planetary gear are eccentric via the second support shaft and the engagement notch of the connecting body. Since the second spindle is engaged and the second spindle can move within the engagement notch, when the rotation axis of the motor is rotated, the rotation of the rotation axis is performed via the rotating body and the first spindle. It is transmitted to the planetary gear. Since the planetary gear meshes with the ring-shaped internal teeth and performs planetary rotation, the rotation of the rotating shaft is greatly reduced. In the planetary rotation of the planetary gear, the second support shaft moves in and out along the radial direction of the annular internal teeth in the engagement notch portion of the connecting body, so that the second support shaft is positioned at the outermost position of the engagement notch portion. , The output shaft rotates slowly. When the second support shaft is at the innermost position of the engagement notch, that is, very close to the first support shaft, the output shaft rotates rapidly. Therefore, while this planetary gear makes one rotation inside the annular internal teeth, there are portions where the speed increases at four locations as shown in FIG. 3, and the rotation speed of the output shaft changes at four locations.

[0007]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of a variable speed motor according to the present invention will be described below in detail with reference to the drawings. 1 and 2
Is a rotating shaft of the motor 2, and an end of the rotating shaft 1 is provided with one surface 3a of a flat rotating body 3 and another surface 3b of the rotating body 3
Is provided with a first support shaft 4 at a position eccentric to the rotation shaft 1.

A planetary gear 5 is rotatably provided on the first support shaft 4, and the planetary gear 5 is
The planetary gear is configured to mesh with the ring-shaped internal teeth 6 provided at the outer positions corresponding to the outer periphery of the gear. The first support shaft 4 is provided at the axis of the planetary gear 5.

A substantially rectangular plate-like connection having an output shaft 8 concentric with the rotary shaft 1 is connected to a second support shaft 7 implanted at a position eccentric from the shaft center of the planetary gear 5. The engagement notch 10 of the body 9 is operably engaged with the engagement notch 10, and the engagement notch 10 is formed along the radial direction of the annular internal tooth 6.

When the planetary gear 5 rotates planetarily along the ring-shaped internal teeth 6, the second support shaft 7 engages with the engagement notch 1.
0, and moves within the range of the distance d.
The output shaft 8 rotates at the lowest speed when the support shaft 7 is located at the outermost position of the distance d, and the output shaft 8 rotates at the highest speed when the second support shaft 7 is positioned at the innermost position of the distance d. As shown in FIG. 3, the rotation state is five at three rotations (denoted by A, B, C, D, and E).
Can be obtained a fluctuation speed at which a portion of high rotation occurs. That is, according to the relationship between the diameters of the planetary gear 5 and the ring-shaped internal teeth 6, when the planetary gear 5 rotates n times, the speed change amount can be changed by the value of the eccentricity d by m.

Next, in the above configuration, when the motor 2 is operated to rotate the rotating shaft 1, the first support shaft 4 of the rotating body 3 is rotated.
, The planetary gear 5 rotates planetarily along the ring-shaped external teeth 6. The second support shaft 7 of the planetary gear 5 reciprocates within the engagement notch portion 10 of the connecting body 9 within the range of the distance D, the connecting body 9 rotates, and the output shaft 8 rotates.

Therefore, the rotation of the rotating shaft 1 of the motor 2 is caused by the planetary rotation of the planetary gear 5 as described above.
The power is transmitted to the output shaft 8 via the support shaft 7 and the coupling body 9 with a variable speed, and the output shaft 8 can be decelerated and rotated with the variable speed.

For this reason, when a pachinko tulip or the like is attached to the output shaft 8, for example, a variable speed rotation similar to an operation of rotating with a variable speed by conventional program control can be performed purely mechanically.

[0014]

Since the variable speed motor according to the present invention is constructed as described above, the rotation speed of the motor is transmitted to the output shaft through the support shaft provided eccentrically to the planetary gear, thereby changing the variable speed motor. And the rotation of the output shaft with
The fluctuation speed of the output shaft can be obtained by a pure mechanical structure.
