Embodiment Construction

[0016] A preferred embodiment of the present invention is: see Fig. 1 and Fig. 2. The magnetic gear for non-contact space cross transmission is made of NdFeB permanent magnet material through bonding and pressing. Its outer surface is smooth and complete. Heteropolar multi-pole magnetic gears. Figure 1 shows that the non-contact space cross transmission magnetic gear is a complete cylinder, and Figure 2 shows that the magnetic pole inclination angle is 45° helix angle. As shown in Figure 3, the two above-mentioned magnetic gears are installed according to the space cross axis, the two magnetic gears are non-contact, and there is an effective gap between them, and the 45° magnetic poles of the two magnetic gears are exactly matched to realize the transmission. The gear transmission of the present invention is not a tooth meshing transmission, but relies on the attraction and repulsion between the positive and negative poles of the magnetic gears to generate torque to realize t...

Abstract

The invention relates to a magnetic gear for the non-contact space cross transmission and a manufacture method and application thereof. The invention is applied on the dustless manufacture delivery mechanism and equipment which has the transmission request to the space cross axle. The invention comprises a hollow cylindrical magnetic gear cemented and compressed by neodymium iron boron permanent magnetism material, the magnetic poles are acquired by multi-pole radial magnetizing, and arranged on the outer surface in a helical way at 45 degrees, and the adjacent magnetic poles are different poles. The two magnetic gear spaces are crossly installed and used, the two magnetic gears are in a non-contact type, an effective gap is left between the two magnetic gears, and the torque can be generated through the attractive force and the expulsive force between the magnetic poles, to enable a driving gear to drive a driven gear to rotate. The invention has the advantages that the dust and mechanical wear can be prevented, the noise is low, the vibration is small, the invention is secure and reliable, and the service life is long.

Description

technical field [0001] The invention relates to a magnetic gear and its manufacturing method and application, in particular to a magnetic gear for non-contact space cross transmission and its manufacturing method and application. The gear is used in the transmission device or equipment, especially in the occasion that requires the production environment to be dust-free, and the transmission device or equipment that has space crossing requirements for the transmission direction of the shaft. Background technique [0002] Due to the contact transmission of traditional mechanical gear transmission mechanisms, particles and dust will inevitably be generated during the working process. In some high-tech fields, the requirements for the production environment are very strict, so in today's transmission technology, there are non-gear contact magnetic gears with the advantages of high cleanliness and no wear. However, in the previous magnetic gear technology, the transmission betwe...
