The specific embodiment
Following structure accompanying drawing is described further description to the embodiment of the present invention.
Fig. 1-4 have shown the coiled electrical magnet of built-in inclined plane force increasing mechanism and have been applied to the constructional drawing of elevator brake.
As shown in Fig. 1-4, the electromagnet of the built-in inclined plane force increasing of the present embodiment mechanism comprises yoke 20, is arranged on magnet coil 30 in yoke 20, armature 35, return springs 25, binding bolt 15, clamp nut 17, inclined plane force increasing mechanism 200.Inclined plane force increasing mechanism 200 is set in yoke 20 and makes yoke 20 directly drive inclined plane force increasing mechanism 200, by this mechanism, the electromagnetic force of yoke 20 is amplified β doubly (β is not less than 1).
Binding bolt 15 runs through yoke 20, and screws in successively clamp nut 17, jam nut from the outer end, and the other end is captiveed joint with brake shoe 40 after passing armature 35.
inclined plane force increasing mechanism 200 is arranged at 20 of binding bolt 15 and yokes, yoke 20 forms inserts groove, this inserts the groove inclined plane force increasing mechanism 200 of packing into, inclined plane force increasing mechanism 200 comprises that kink is at the step disk 210 of binding bolt 15, be fastenedly connected the clutch plate 220 at binding bolt 15, the active drive that relies on yoke 20 to promote tiltedly overlaps 230, active drive tiltedly cover 230 is fixed in yoke 20, step disk 210 is fixed in armature 35, relative clutch plate 220, step disk 210 is in the outside, leave the gap between the end of its inner and clutch plate 220, and active drive tiltedly cover 230 is placed in outside clutch plate 220, the bevel phase of the oblique cover 230 of active drive is corresponding with the position, gap of clutch plate 220 with aforementioned step disk 210, thereby the three surrounds a zone, the slide mass 240 of packing in this zone, slide mass 240 all contacts with above three.As Figure 1-3, slide mass 240 is selected rolling body, is preferably ball.As shown in Figure 4, slide mass 240 is selected wedge.
