Embodiment
The invention will be further described below in conjunction with concrete drawings and Examples.
As shown in the figure, the present invention mainly is made of parts such as spring sheet 1, friction plate 2, coil baffle plate 3, frame 4, coil liner 5, coil 6, magnet steel skeleton 7, magnet steel 8, support 9, rivet 10, fixed hole 11, leakproof magnet passage 12 and retainer rings 13.
This has the electromagnetic brake of permanent magnet, comprise spring sheet 1, friction plate 2, coil baffle plate 3, frame 4, coil liner 5, coil 6, magnet steel skeleton 7, magnet steel 8 and support 9, all offer fixed hole 11 on every flat spring sheet 1, some flat spring sheets 1 are installed in corresponding position in the friction plate 2 by rivet 10; Be socketed with frame 4 on support 9, be provided with coil 6 between support 9 and frame 4, the inwall of coil 6 has coil liner 5, has coil baffle plate 3 at the front-end face of coil 6; Between the inner end of frame 4 and support 9, be provided with magnet steel skeleton 7, in magnet steel skeleton 7, be provided with some magnet steel 8, form leakproof magnet passage 12 between the end of adjacent two magnet steel 8, described leakproof magnet passage 12 is bending-like (as Fig. 3, Fig. 5 and Fig. 6) or curved shape (as Fig. 2 and Fig. 4).Make the magnetic line of force of straight line shape in leakproof magnet passage 12, not pass through, as Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6.
Also include circular retainer ring 13, some flat spring sheet 1 equal one are connected on the outer ring body of described retainer ring 13.Some flat spring sheets 1 are distributed on the outer ring body of described retainer ring 13.
Having permanent magnetism electronics brake spring sheet 1 has three holes to be fixed on the front end of actuating motor, support 9 has 4 holes to be fixed on the rear end of motor, friction plate 2 cooperates brake with frame 4, support 9, when electrical power, produce the magnetic force that magnetic force is just offset magnet steel 8 during charged excitation magnetic coil 6, friction plate 2 is separated under the elastic force effect of spring sheet 1 with frame 4, support 9, make the work of motor stabilizability ground; When actuating motor quits work, charged excitation magnetic coil 6 dead electricity, magnetic force made friction plate 2 overcome the elastic force and frame 4, support 9 merging, braking motors thus of spring sheet 1 in magnet steel 8 produced.
