Description

technical field

[0001] The invention relates to a magnetic meshing transmission device, in particular to an adjustable-speed planetary magnetic meshing flexible transmission device. Background technique

[0002] At present, mechanical gears are the most widely used fixed speed ratio rotating devices with good performance, but there are mechanical friction and losses in gear transmission, which requires auxiliary lubrication devices, cooling devices and good maintenance. In addition, the gear transmission is a rigid transmission, which itself cannot realize the absorption of the impact torque and the torque limit protection transmission.

[0003] Compared with conventional mechanical gear transmission, magnetic mesh transmission eliminates the friction loss and mechanical failure caused by tooth meshing, no meshing noise, no oil lubrication and cooling device for gear transmission, and no other mechanical maintenance except for bearings. If configured The regular automatic r...

Examples

Embodiment 1

[0031] Such as figure 1 As shown, an adjustable speed planetary magnetic meshing flexible transmission device includes a casing 1, a planetary magnetic wheel assembly, an outer magnetic ring assembly, a central magnetic wheel assembly and an outer ring speed regulating assembly. The planetary magnetic wheel assembly, the outer magnetic coil assembly and the central magnetic wheel assembly are all arranged in the casing 1, and the outer ring speed regulating assembly is connected to the outer magnetic coil assembly. Corresponding bearings are provided between the planetary magnetic wheel assembly, the central magnetic wheel assembly, the outer magnetic ring assembly and the casing, so that the planetary magnetic wheel assembly, the central magnetic wheel assembly, and the outer magnetic ring assembly can all rotate, forming three concentric rotating bearings .

[0032] The described planetary magnetic wheel assembly comprises a planetary carrier shaft extension 2, a planetary ...

Embodiment 2

[0044] This embodiment is basically the same as Embodiment 1, the difference is: as figure 2 , Figure 4 As shown, the present embodiment is provided with four sets of symmetrically distributed planetary magnetic wheel sets, and the relationship between the axial arrangement number W of the outer magnetic ring, the axial arrangement number X of the planetary magnetic wheels and the axial arrangement number Z of the central magnetic wheel is X=W+ 1=Z+1, W:X:Z=3:4:3. Such as figure 2 As shown, in this embodiment, planetary magnetic yokes 6 are arranged on the outermost planetary magnetic wheels in a staggered arrangement.
