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...
