Abstract

PURPOSE:To eliminate a noise by aligning magnets on the outer periphery of a rotatable wheel to form magnetically coupling gears, thereby transmitting a force without contact. CONSTITUTION:A shaft 4 is disposed at the center of a disk 1, and magnets 2, 3 are secured to the periphery of the disk 1. The magnets 2 have upper N-poles and lower S-poles, and the magnets 3 have upper S-poles and lower N-poles, and reverse magnets 2, 3 are alternately aligned on the periphery of the disk 1. When the two magnet gears thus formed are approached and one gear is rotated, the other gear will rotate.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a mechanical component in which small pieces of magnets are arranged on the edge of a disk to transmit force like a gear.

Conventional mechanical parts such as gears, reels, and belts that transmit force can only be transmitted through direct contact, but magnetic gears can transmit force without contact.

First, FIG. 1 will be explained. At the center of the disk (1) is a shaft (
4) Yes, a disk can rotate. A magnet (2) and a magnet [3] are fixed around the disk (1). Fix the magnet exactly where the teeth of the gear are. then.

Arrange adjacent magnets so that their polarities are opposite.

In the case of FIG. 1, the magnet (2) has a north pole at the top and a south pole at the bottom. The magnet (3) has an S pole at the top and an N pole at the bottom.

These oppositely oriented magnets (2) and magnets (3) are arranged and fixed around one disc (1) so as to alternate. If two magnetic gears made in this way are brought close together as shown in Figure 1, one of the two magnetic gears will rotate without having to touch them directly.

The other magnetic gear also rotates.

If the shape is as shown in Figure 2, the magnetic gears will repel each other and try to return to the shape shown in Figure 1. FIG. 1 shows matching, and FIG. 2 shows mismatching. As a result, the two magnetic gears rotate in complete synchronization. There is a method of transmitting force without synchronization that involves putting a belt on the reel.

When the reel is rotated for a long time, a slight slippage occurs between the reel and the belt, and the rotation of the two reels becomes out of synchronization. On the other hand, magnetic gears, like gears, rotate synchronously.

The advantage of magnetic gears is that they rotate synchronously. B. It is a non-contact point. Ha, extremely low noise. 2. When transmitting force, there is a lot of energy loss. Eh, if you partition the space between the two magnetic gears, you can use it for waterproofing.

A structural feature of this magnetic gear is that it has a matched state and a mismatched state. This is the relationship between FIG. 1 and FIG. 2.

As an example of applying magnetic gears, as shown in Figure 6, the disks of two magnetic gears are not placed on the same plane, but one above the other.

shift and position. In other words, the disks of the two magnetic gears are located on separate parallel planes.

As another application example, as shown in FIG. 4, a magnet gear is constructed by rotating the magnet 90 degrees and raising it up. Make sure that the polar axis direction (8) of the pick magnet faces the center of the magnet gear. The polar axis direction (8) is the direction when a straight line is drawn from the south pole (7) of the magnet to the north pole (6). If we look at the earth as a magnet, the straight line connecting the south and north poles is the earth's axis. Words that correspond to the earth's axis.

It is the polar axis.

As another example of application, magnet pieces are arranged and fixed on a one-turn belt as shown in FIG. Reverse the polar axis vectors of adjacent magnets.

[Brief explanation of drawings]

FIG. 1 shows the present invention. FIG. 2 shows the present invention. Whistle 6 when the invention is in an inconsistent state. FIG. 4 shows the embodiment of the invention. FIG. 5 shows the embodiment of the invention. Figure 6 is an explanatory diagram of the polar axis direction of the magnet.

Claims (1)

[Claims] Magnets (2) and magnets (3) are arranged and fixed alternately around the outer periphery of a rotatable ring. The difference between magnet (2) and magnet (3) is that the north and south poles are oriented 180 degrees in the opposite direction. The magnetic gear configured as described above.
