Abstract

PURPOSE: To provide a shaft coupling which can absorb a shock when an impact torque is applied, which is cushioned in a start and which can be started slowly. CONSTITUTION: A stator 1 is arranged and installed in the center, an input rotor 2 is arranged and installed on one side of the stator 1 and an output rotor 3 is arranged and installed on the other side in such a way that they are coaxial on a shaft, and magnets 4 of the same number of pieces are arranged and attached to the input rotor 2 and the output rotor 3 in such a way that S-poles and N-poles are mutually alternative. In addition, the stator 1 is made of a weakly magnetic substance such as aluminum or the like, it is constituted in such a way that a pole 5 made of a high-specific-permeability material such as Permalloy, an iron-based amorphous material or the like is built in, the rotors 2, 3 and the stator 1 are brought close to each other in a noncontact state, and a shaft coupling is formed.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention relates to an input rotor, a stator,
Since the power is transmitted by the magnetic circuit formed between the output rotor and the output rotor, it is considered that the attractive force and the repulsive force acting on the input rotor and the output rotor are equal to each other according to Coulomb's law. Therefore, by changing the distance from the rotation axis by the pole that incorporates the input and output force points in the stator,
It can be used as an energy source in the future because the increase and decrease in output can be seen.

2. Description of the Related Art With a conventional joint, it is impossible to absorb a shock at the time of impact and to cushion and start at the time of starting.

[0003]

Since a long time ago, many people have considered magnet couplings, clutches, etc., but the energy required for switching the magnetic force consumes the input energy and sees completion. Absent. The present invention solves these problems and enables completion.

[0004]

[Means for Solving the Problems] On both sides of the stator (1),
The input rotor (2) and the output rotor (3) are coaxially arranged, and the same number of magnets (4) are arranged in the input rotor (2) and the output rotor (3) alternately in SN, The stator (1) should be made of a weak magnetic material (aluminum, etc.) and the pole (5) made of a material (permalloy, iron-based amorphous, etc.) with a high relative permeability that is a multiple of the magnet. Is a joint made of magnets.

[0005]

When the input rotor (2) is rotated, the output rotor (3) rotates synchronously. The torque at that time can be changed by the input rotor (2) to obtain energy.

Embodiments of the present invention will be described below. (I). The input rotor (2) and the output rotor (3) are coaxially arranged on both surfaces of the stator (1). (B). The same number of magnets (4) are arranged alternately in the input rotor (2) and the output rotor (3). (C). The stator (1) is made of a weak magnetic material (aluminum, etc.) and has a high relative magnetic permeability that is a multiple of the magnet (permalloy,
It is composed of a product incorporating a pole (5) made of iron-based amorphous or the like. The present invention has the above-described structure, and uses a magnetic path that is a multiple of the magnetic poles assembled in the stator (1) and a large gap in the magnetic path (by calculation of the vector of magnetic force lines) that has not been considered in the past. Is operated in 5 steps, but when one step out of them and starting from a stationary state requires twice the torque as in the operating state, a flywheel effect is applied to the input / output shaft to start up. Only the input gives twice the normal torque. In the manufactured prototype, we observed a torque variation of about 17% at a rotation of about 20 rpm.

[Effects of the Invention] Useful for solving future energy resources and environmental problems.
