Permanent magnet transmission speed change mechanism

The utility model discloses a permanent magnet transmission speed change mechanism, and relates to the technical field of permanent magnet transmission. Comprising a bottom plate, and the top end of the bottom plate is fixedly connected with a shock pad; the adjusting assembly is mounted on the bottom plate; the power assembly is mounted at the moving end of the adjusting assembly; and the output device is mounted on the bottom plate. Through the arrangement of the adjusting assembly, when the air gap between the permanent magnet disc and the conductor disc is adjusted, the output end of the first motor rotates, the permanent magnet disc is made to move through transmission, and the gap between the permanent magnet disc and the conductor disc is controlled on one side, so that the speed changing and adjusting process of permanent magnet transmission is controlled; the transmission of the vibration of the first motor is reduced by using a coupler and a shock pad, the rotating speed of the second motor is slow,
