Magnetic loop type infinitely variable-speed device

Abstract

Disclosed in the invention is a magnetic loop type infinitely variable-speed device comprising an active permanent magnetic ring in an active rotation manner and an intermediate permanent magnetic ring. When the intermediate permanent magnetic ring enters the active permanent magnetic ring, the intermediate permanent magnetic ring is driven to make rotation by a magnetic torque generated by cutting magnetic force lines mutually; the intermediate permanent magnetic ring drives a spline shaft to make synchronous rotation; and a driving force is inputted into a gear variable-speed unit. In addition, the magnetic loop type infinitely variable-speed device also includes a static braking permanent magnetic ring. After exit of the rotating intermediate permanent magnetic ring, the braking permanent magnetic ring sleeves the intermediate permanent magnetic ring and rotation of the intermediate permanent magnetic ring is stopped by a magnetic torque generated by cutting magnetic force lines mutually, so that the spline shaft and the gear variable-speed unit connected with the spline shaft rotates at a reduced speed or stops rotating. According to the magnetic loop type infinitely variable-speed device, infinitely variable-speed, braking, and overloaded slip frequency protection functions can be realized simultaneously; and the torque is transmitted by the magnetic field, so that the harmful vibration, wearing, and breakage can be eliminated substantially, the service life of the variable-speed device can be prolonged, and the damage caused by overloading is avoided.
