Chinese patent ZL 2,016 2 0220312.8 is disclosed " desk permanent-magnet variable-speed clutch ", and structure is passed including permanent magnetism Motivation structure and air gap governor motion, its contact Permanent Magnetic Gear transmission mechanism includes permanent magnetic disk and conductor disc, sets between permanent magnetic disk and conductor disc There is air gap, the desk permanent-magnet variable-speed clutch is connected between motor and load, air gap passes through air gap governor motion push-and-pull permanent magnetism Disk is adjusted, and the contact Permanent Magnetic Gear transmission mechanism is double coupled structures, wherein permanent magnetic disk（Magnet rotor）Including disk one and disk two, conductor disc （Conductor rotor）Including godet one and godet two, disk one is matched with godet one, and disk two is matched with godet two.Disk one and magnetic Disk two is connected by connecting rod, and when disk two is promoted by permanent magnetic disk adjusting set, disk one is orthokinetic with disk two.The structure Between middle conductor rotor and magnet rotor or realize it is multigroup couple right, be conducive to improving transmitting torque, but disk one and disk two Between connecting rod structure make its structure become complicated heavy, for the occasion that some low costs are required, it is impossible to popularization and application.
The content of the invention
The purpose of this utility model is to provide a kind of magnetic coupling arrangement of permanent-magnet eddy current flexible gearing, overcomes existing skill The deficiency of art, while the synchronizing moving of double permanent magnetic disks is realized, simplifies permanent magnet rotor structure, reduces the system of permanent magnet transmission product This is caused, extension permanent-magnet eddy current transmission product development and application.
To achieve these goals, the technical solution of the utility model is such：
A kind of magnetic coupling arrangement of permanent-magnet eddy current flexible gearing, including p-m rotor and conductor rotor, the permanent magnetism Rotor is provided with permanent magnetic disk one and permanent magnetic disk two, and the conductor rotor is provided with conductor disc one and conductor disc two, in conductor disc one Be provided with conductor one, conductor disc two is provided with conductor two, be provided with air gap one between permanent magnetic disk one and conductor disc one, permanent magnetic disk two with lead Air gap two is provided between body disc two, is connected as a body by space-stop rack between the conductor disc one and conductor disc two, the permanent magnetism Only linked together by adapter sleeve with inner edge between disk one and permanent magnetic disk two, position of the conductor one in conductor disc one with Position of the conductor two in conductor disc two is arrangement in the same direction.
The inner edge connection wheel hub one of the conductor disc one.
The inner edge connection wheel hub two of the adapter sleeve.
The inner side of the wheel hub one is provided with the seam for disposing axle end baffle plate.
The wheel hub two is provided with the cervical region of installation locking disk.
Compared with prior art, the beneficial effects of the utility model are：
1）Although permanent magnet rotor structure is simplified, remain to meet the synchronization-moving reliability requirement of double permanent magnetic disks, This has great meaning to the manufacturing cost for reducing permanent magnet transmission product.
2）Relative to the p-m rotor of common middle dish structure, this utility model provides the new think of that a kind of air gap is adjusted Road, has a far reaching influence in terms of extension permanent-magnet eddy current transmission product development and application.
