Description

[Detailed Description of the Invention] (Technical Field) The present invention relates to a device that converts rotational motion into linear reciprocating motion by utilizing the attraction and repulsion between permanent magnets, and particularly relates to a vibrator that obtains a vibration output for rotational input. Regarding equipment.

(Technical Background) Some conventional vibrators apply rotational force from a motor to a crank structure and convert it into linear reciprocating motion.

However, the crank tfM (M is the
! There are many things that need to be done, and production can be difficult.

[Purpose of the invention]

The present invention has been made based on the above points, and an object of the present invention is to provide a vibrator device that has a simple structure and is easy to manufacture.

[Summary of the invention]

In order to achieve this objective, in the present invention, a permanent magnet is provided on the rotating plate, and a permanent magnet is placed on the axially movable plate, which is placed opposite to the rotating plate, to face the permanent magnet of the rotating plate-F. The present invention provides a vibrator device in which the permanent magnets arranged on the rotary plate and the axially movable plate have magnetic poles alternately different in the circumferential direction.

〔Example〕

The present invention will now be described by way of example with reference to the accompanying drawings.

FIG. 1 is a longitudinal sectional view of an embodiment of the present invention, in which 1 is a main body that supports two discs 2Δ and 2B facing each other. One disc 2A is rotatably supported relative to the main tree 1 but not axially movable, and the other disc 2B is axially movable but supported unrotatably.

Permanent magnets 3 are attached to mutually opposing surfaces of both discs 2A and 2B. The permanent magnets 3 of both discs 2A are attracted to or repelled by each other.

This attraction and repulsion is generated by rotating the rotary disk 2Δ, resulting in reciprocating motion of the axially moving disk 2B in the axial direction.

In order to perform such an operation, the rotation f of the rotating disk 2Δ
41/I is pivotally supported on the bearing 5 of the main body 1, and the thrust is 10
to prevent axial movement. Further, the shaft 7 is supported by the movable bearing 8 in the axially moving disc 2B, and rotation thereof is prevented.

Then, an inertial weight W is installed at the tip of the arm extending from @7, and is necessary when the main body 1 is to be vibrated by reaction.In this case, the main body 1 is attached to the object that is to be vibrated. .

Figures 2 and 3 show an example of the arrangement of the permanent magnets 3 on the discs 2A and 2B. FIG. 3 shows disk-shaped magnets 3' taken at 60° intervals (=J).

Although this magnet arrangement is required to be symmetrical, the angular spacing etc. can be set arbitrarily.

[Modified example]

In the above embodiment, the vibration of the axially moving disk 2B is caused to act on the inertial weight W, but the shaft 7 may be directly connected to the object. There are various ways to use this vibration output.
The shaft 7 of the shaft 01 and the disc 2B may be modified accordingly.

Further, some kind of swivel may be provided to prevent the permanent magnets 3 of the rotating disk 2A and the axially moving disk 2B from coming into contact with each other during attraction.

〔Effect of the invention〕

As described above, the present invention includes a rotating disk and an axially moving disk that are placed opposite each other, and permanent magnets are installed on each of the opposing surfaces to rotate the rotating disk and vibrate the axially moving disk. Therefore, it is possible to provide a vibrator device that has a simpler structure of the mechanical part than that of a conventional crank gate structure and is easier to manufacture.

Claims (1)

[Claims] A rotating disk that does not move in the axial direction and an axially moving disk that does not move rotationally are arranged facing each other, and permanent magnets are arranged at the same pitch on the opposing surfaces of each disk, and the rotating disk is rotated. The vibrator device is configured to magnetically attract and repel the axially moving disk so as to cause the axially moving disk to vibrate in the axial direction.
