Embodiment Construction
[0017] The present invention will be described in detail below.
[0018] The horseshoe-shaped permanent magnet energy-collecting gear of the present invention comprises two parts: a wheel base and a horseshoe-shaped permanent magnet energy-collecting tooth, wherein:
[0019] Wheel base part: the wheel base is made of non-ferromagnetic materials (such as aluminum, aluminum alloy or carbon fiber), with gaps at equal intervals on the circumference of the rim of the wheel base, and a shaft mounting hole is provided in the center of the wheel base to Connect with drive motor.
[0020] Horseshoe-shaped permanent magnet energy-gathering tooth part: The permanent magnet energy-gathering tooth is composed of two parts: a horseshoe-shaped permanent magnet and a bar-shaped permanent magnet. The combination of the two permanent magnets is as follows: the bar-shaped permanent magnet is embedded in the horseshoe-shaped permanent magnet opening. The height of the bar-shaped permanent magne...

The invention discloses a U-shaped permanent magnet energy-collecting gear. A wheel base is made of nonferrous magnetic material, openings are disposed on the rim of the wheel base equidistantly, and a rotating shaft mounting hole is arranged in the center of the wheel base; a U-shaped permanent magnet energy-collecting tooth part comprises a U-shaped permanent magnet and a bar permanent magnet which is embedded in the opening of the U-shaped permanent magnet, and the S pole of the bar permanent magnet faces to the S pole of the U-shaped permanent magnet, and the N pole of the bar permanent magnet faces to the N pole of the U-shaped permanent magnet; the U-shaped permanent magnet and the bar permanent magnet are made of hard magnetic material; U-shaped permanent magnet energy-collecting teeth are embedded in the openings of the rim of the wheel base, the opening of the U-shaped permanent magnet faces to the outer side of the rim, and the N pole and the S pole of the U-shaped permanentmagnet are spaced along the circumference of the rim; two U-shaped permanent magnet energy-collecting gears are oppositely mounted in parallel, wherein the N pole teeth of one U-shaped permanent magnet energy-collecting gear correspond to the S pole teeth of the other U-shaped permanent magnet energy-collecting gear, and a working air gap is remained between the two U-shaped permanent magnet energy-collecting gears.
Description
technical field [0001] The invention belongs to the technical field of gear torque transmission machinery, and in particular relates to a permanent magnet energy gathering gear. Background technique [0002] In today's power transmission technology field, a non-gear contact "permanent magnet gear" transmission technology has emerged. The Chinese patent "a horseshoe-shaped permanent magnet gear and its torque transmission system" (application number: 200610112939.2) discloses this technology. Although this technology effectively aggregates the magnetostatic energy on the surface of the permanent magnet teeth, it also has the disadvantage of wasting the space of the permanent magnet teeth, which is not conducive to the further increase of the magnetostatic energy on the surface of the permanent magnet teeth. Contents of the invention [0003] The purpose of the present invention is to provide a horseshoe-shaped permanent magnet energy-collecting gear technology to reduce th...
