Problems solved by technology

The disadvantage of this technology is that it can only rotate on the same axis, and cannot transmit power between the two axles, and there is no mosaic structure between the permanent magnet energy-gathering teeth and the non-ferromagnetic wheel base, so there is more magnetic flux leakage

Embodiment Construction

[0020] The following content is a detailed description of the present invention in conjunction with the accompanying drawings, but should not be construed as a limitation of the present invention.

[0021] Please refer to Fig. 1, which is a schematic diagram of the general structure of the present invention. The wheel base 1 is made of non-ferromagnetic material (such as but not limited to: polytetrafluoroethylene, copper or aluminum, etc.), the circumference of the wheel rim is provided with gaps at equal intervals, and the center of the wheel base 1 is provided with a wheel shaft hole 3, To fix the wheel base 1 on the wheel axle. Permanent magnet energy-gathering teeth 2 are inlaid in the openings of the wheel base 1. The permanent magnet teeth 2 are dark teeth, and the surface thereof transitions smoothly with the rim, but here the magnetic field strength is highlighted on the non-ferromagnetic rim. A permanent magnet "field tooth" is formed.

Abstract

The invention relates to a permanent magnetic energy-collecting gear, which is formed by permanent magnetic energy-collecting teeth and wheel base, wherein said wheel base is made from non-iron magnetic material; the edge of wheel base is distantly arranged with cuts; the center of wheel base has rotation axle mounting hole; the permanent magnetic energy-collecting teeth are groove bodies, and made from iron magnetic material; the center of groove is embedded with permanent magnet made from rigid magnetic material; the non-iron magnetic embed object is filled between permanent magnet and groove wall; the permanent magnetic energy-collecting teeth are mounted inside the cut of wheel edge; the groove wall is flat with the wheel base; the groove is toward to the outer side of wheel edge; the permanent magnets on the circumference of wheel edge are distantly arranged with N and S poles; two gears are parallel mounted, while N pole of one wheel is opposite to the S pole tooth of another wheel; and two gears have working space between them. With said structure, when one wheel rotates, the permanent magnetic teeth, via the adsorption force and repulsion force between teeth, transmit torque, to rotate another gear.

Description

technical field [0001] The invention belongs to the technical field of gear torque transmission machinery. Specifically, it relates to a permanent magnet energy gathering gear. Background technique [0002] In today's power transmission technology, a non-gear contact "permanent magnet gear" transmission technology has been produced. Such as the 49-page coupling technology and the 141-page permanent magnet torque valve technology in the book "Permanent Magnet Mechanism" (Beijing University of Technology Press). The advantage of this permanent magnet gear technology is that the inner teeth do not touch the outer teeth, there is no frictional resistance, no wear, and no noise. The disadvantage of this technology is that it can only rotate on the same axis, and cannot transmit power between the two axles, and there is no mosaic structure between the permanent magnet energy-gathering teeth and the non-ferromagnetic wheel base, so there is more magnetic flux leakage.
