Embodiment
Below in conjunction with accompanying drawing, specific embodiment of the invention is further described.
A kind of efficient magnetic current changing brake device of the present invention, comprises first order reducing gear, second level reducing gear and arrestment mechanism as shown in Figure 1, Figure 2 and Figure 3.Wherein said first order reducing gear comprises small Spur gear 4 and the large straight gear 1 meshing with small Spur gear 4; The second described reducing gear comprises bevel pinion 6 and the bevel gear wheel 7 meshing with bevel pinion 6; Described arrestment mechanism is to adopt drum type magnetic rheological brake 9.Described drum type magnetic rheological brake is multi-barrel structure, mainly comprises field coil 16, rotatingshaft 11, left end cap 17, right end cap 10, bolt 15, every magnetic annulus 13, seal ring 14, brake drum 12, keyway 18 and bearing 19.Described rotatingshaft 11 is provided with keyway 18; Described brake drum 12 comprises outer cylinder 12-1 and two drag friction cylinder faces of inner cylinder 12-2, and brake drum is fastened on rotatingshaft 11 by key; Described field coil 16 is arranged on magnetic annulus 13; Described left end cap 17 links together by bolt 15 with right end cap 10; Between described left end cap 17 and right end cap 10, form cavity; Described brake drum 12 is arranged in cavity, has the working clearance of 1mm between brake drum and left end cap 17 and right end cap 10; Described working clearance inside is full of magnetic flow liquid; Between described left end cap 17 and right end cap 10, be provided with seal ring 14; Between described left end cap 17, right end cap 10 and rotatingshaft 11, be provided with bearing 19.
