Rotary break for using magnetorheological fluid

摘要

The present invention relates to a rotary brake is designed using magnetorheological fluids, especially the break with a magnetorheological fluid in, and a rotating plate having a rotational shaft gear on the outer periphery is fixed to the central portion; Interior space portion is formed in a housing which is formed in one side of the plurality of fixed shaft portion space; The fixed shaft is fixed so as to be rotatable in the housing, a plurality of planetary gears engaged with the gear gardenia and the rotary plate; Are formed in the disk shape, the planetary gear is engaged so that the gear gardenia circular hole formed in the central portion is, with the disc being disposed inside the housing; Magnetorheological fluid filled in the space portion of the housing; And is characterized in that it comprises an electromagnetic coil that is installed in the space portion of the housing outer rim. ; to the axis of rotation, according to the subject innovation by inserting the planetary gear between the gear shaft and the disc, such as a high-speed Even when the rotating shaft is rotated at a high speed even if the disc is to be rotated by the reduced rotation can be stably achieved in the brake disc.
