description | The utility model provides a permanent magnet braking device and a downward conveying crossheading belt braking system, and relates to the technical field of coal mine belt braking. The main shaft penetrates through the first shell along the axis of the first shell and is fixedly connected with the first shell through a bearing; an induction ring is fixedly arranged on the front annular inner wall of the first shell; the groove type magnetism isolating cover is fixedly arranged on the main shaft; the mounting seat is sleeved on the main shaft; the motor, the lead screw and the driven disc are all located outside the first shell. The tail end of the lead screw is fixedly connected with an output shaft of the motor, and the lead screw is fixedly sleeved with the driven disc. The transmission rod penetrates through the first shell; and the permanent magnets are fixedly arranged on the outer side wall of the mounting seat along the circumference. According to the eddy current braking principle, the permanent magn |
