specific Embodiment approach 1

[0044]Specific Embodiment 1: As shown in Fig. 1 to Fig. 4, variable speed or constant speed transmission with parallel rotation axes can be realized. Two identical disks are arranged at intervals on the shaft 4. The disk consists of a non-magnetic (and preferably high resistivity) disc 1, a magnetic ring 2 and a non-magnetic (and preferably high resistivity) ferrule 3. The disk 1 and the shaft 4 are concentrically fixed, and the magnetic block of the magnetic ring 2 is magnetized along the axial direction and solidified on the outer circle of the non-magnetic disk 1 alternately along the circumferential direction. Partitioned and alternately magnetized with multiple poles along the axial direction, the non-magnetic ferrule 3 is fixed on the outer circle of the magnetic ring 2, and the end faces of the disc 1, the magnetic ring 2 and the non-magnetic ferrule 3 are flush; on the shaft 5 Set three identical disks at equal intervals, the size of the disks is different or the same ...

specific Embodiment approach 2

[0048] Specific embodiment two: as shown in Figure 6 and Fig. 7, the shaft 5 and the magnetic disk on it in the specific embodiment one are made into an integral part 10 similar to a cylinder with inductive materials (such as copper, aluminum and alloys thereof, etc.); In the first embodiment, the magnetic disk and the component 10 are rotated by using the principle of electromagnetic induction. The transmission in this mode should have sufficient cooling conditions or cooling environment to prevent the overheating radiation of the component 10 from damaging the magnetic coil on the magnetic disk.

specific Embodiment approach 3

[0049] Specific Embodiment Three: As shown in Figures 8 to 10, similar to a mechanical internal gear transmission structure, it can realize variable speed and variable speed transmission with the rotation axis parallel or concentric. The magnetic disk and the shaft 20 are fixed concentrically. The magnetic disk is composed of a nonmagnetic (and preferably high resistivity) disk 16, a magnetic ring 19 and a nonmagnetic ferrule (and preferably high resistivity) 18. The manufacturing method of the magnetic ring 19 And the manufacturing method of magnetic disc is with the manufacturing method of magnetic disc described in the specific embodiment one; On axle 15, magnetic conduction disc 17 is concentrically fixed, and nonmagnetic ring (and preferably high Resistivity) 14, there is a ring groove in the middle of the inner circle of the ring 14, and its width is larger than the thickness of the magnetic disk on the shaft 20, that is, the end face of the magnetic disk on the shaft 20 ...

Abstract

The invention relates to a magnetic transmitter. The magnetic transmitter is concentric in a drive rotary shaft and a driven rotary shaft and is fixed with magnetic discs which consist of a magnetic ring, a round disc for fixing the magnetic ring and a nonmagnetic bushing ring, the magnetic ring is made by that magnet bodies which are alternatively magnetized along an axial polarity or a radial polarity and are integrated along the inner ring or the outer ring of the round disc of the fixed magnetic ring, the magnetic rings, with different sizes and quantities, on the drive rotary shaft and the driven rotary shaft are combined in a noncontact engaging method to realize the axial, concentrically or cross movement at a constant speed or variable speed. Compared with the existing magnetic transmitter device, since that the engaging force between the drive magnetic disc and the driven magnetic disc of the magnetic transmitter is large and the transmitted power of each unit volume is high, a comparatively high power transmission can be realized and so the magnetic transmitter has wide application.

Description

technical field [0001] The invention relates to a magnetic transmission device, which belongs to the transmission technology. Background technique [0002] Magnetic transmission has excellent characteristics such as non-contact, no friction, no vibration, no noise, no lubrication, no maintenance, environmental protection and overload protection, so it has broad application prospects and is increasingly valued by people. Many magnetic transmission technologies and magnetic transmission devices have been born, and some have been practical and popularized. However, the existing magnetic transmission device has a small meshing force between the main and slave wheels, and cannot transmit high power, and most of them are driven concentrically or parallel to the axis of the main and slave axes, which can realize the crossing of the axis lines and the transmission of variable speed. few. Although some magnetic transmission devices can realize axial crossing and variable speed tran...
