Summary of the invention
The technical problem that actual needs of the present invention solves is: dish-type eddy-current coupling radial dimension is larger, if when heart height is inadequate among the use equipment, just needs to transform base, has increased duration and work difficulty; The dish-type eddy-current coupling can produce an axial force when acting, must have one group of thrust bearing 7 to support this axial force, and cost is higher, and stability is not high; Produce larger wind resistance when the heat dissipation element on the shrouding 8 rotates, cause Efficiency Decreasing, energy consumption strengthens.
The present invention is by the following technical solutions:
A kind of vortex ring coupler, comprise driving shaft 5, bearing axle 6, rotor assembly, described driving shaft 5, bearing axle 6, the coaxial setting of rotor assembly, described rotor assembly comprises the first carbon steel ring 3, axial plane is the Contraband font in described the first carbon steel ring 3, described driving shaft 5 is fixedly connected with described the first carbon steel ring 3 outer faces, and the medial surface of described the first carbon steel ring 3 and conductor loops 2 are fitted and connected; Described rotor assembly also comprises permanent-magnetic clamp 1, it is inboard and corresponding with described conductor loops 2 that described permanent-magnetic clamp is arranged at described conductor loops 2, one end face of described permanent-magnetic clamp 1 is corresponding with described the first carbon steel ring 3 inner faces, the other end is fixedly connected with bearing axle 6, and described permanent-magnetic clamp 1 inboard is fitted and connected with the second carbon steel ring 4.
Further, described permanent-magnetic clamp 1 comprises at least one pair of arc-shaped permanent magnet.
Further, described the first carbon steel ring 3 peripheries radially are provided with a circle fin 3a.
A kind of above-mentioned annular coupler, described permanent-magnetic clamp 1 is exchanged with conductor loops 2 positions.
The vortex ring coupler of structure of the present invention provides a kind of eddy-current coupling of annular, the eddy-current coupling of dish type compared to existing technology, and with original permanent magnetic disk rotor, the conductor disc rotor is transformed to permanent-magnetic clamp 1 and conductor loops 2, forms the vortex ring coupler.
Beneficial effect of the present invention is:
1) greatly reduced the radial dimension of eddy-current coupling, avoided having reduced the engineering cost expenditure owing to the excessive base of transforming of eddy-current coupling radial dimension;
2) avoid eddy-current coupling to produce axial thrust, the thrust self-balancing of hoop need not thrust bearing, and simplified structure reduces cost, has increased simultaneously reliability and stability.
3) fin is disposed radially, and produces less windage during rotation, has improved efficient, has reduced energy consumption.
