Detailed description of the invention
Structure Figure is described further description to the embodiment of the present invention below.
Fig. 1-4 shows the coiled electrical magnet of built-in inclined plane force increasing mechanism and is applied to the constructional drawing of elevator brake.
As Figure 1-4, the electromagnet of the built-in inclined plane force increasing mechanism of the present embodiment, comprise yoke 20, the magnet coil 30 be arranged 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 be set in yoke 20 and make yoke 20 Direct driver inclined plane force increasing mechanism 200, by this mechanism, the electromagnetic force of yoke 20 being amplified β doubly (β is not less than 1).
Binding bolt 15 runs through yoke 20, and screws in clamp nut 17, jam nut successively from outer end, and the other end is fixedly connected with brake shoe 40 through after armature 35.
Inclined plane force increasing mechanism 200 is arranged between binding bolt 15 and yoke 20, yoke 20 is formed and inserts groove, this is inserted groove and loads inclined plane force increasing mechanism 200, inclined plane force increasing mechanism 200 comprises the step disk 210 of kink at binding bolt 15, be fastenedly connected the clutch plate 220 at binding bolt 15, the active drive relying on yoke 20 to promote tiltedly overlaps 230, active drive is tiltedly overlapped 230 and is fixed on yoke 20, step disk 210 is fixed on armature 35, relative clutch plate 220, step disk 210 is in outside, gap is left between the end of its inner and clutch plate 220, and active drive is tiltedly overlapped 230 and is placed on outside clutch plate 220, the bevel phase that active drive tiltedly overlaps 230 is corresponding with the position, gap of clutch plate 220 with aforementioned step disk 210, thus three surrounds a region, slide mass 240 is loaded in this region, slide mass 240 all contacts with above three.As Figure 1-3, slide mass 240 selects rolling body, is preferably ball.As shown in Figure 4, slide mass 240 selects wedge.
The one side that clutch plate 220 and step disk 210 contact with slide mass 240, when both are simultaneously wherein inclined-planes, if when the one side that clutch plate 220 contacts with slide mass 240 is inclined-plane, the one side that step disk 210 contacts with slide mass 240 is exactly plane; Otherwise when the one side that clutch plate 220 contacts with slide mass 240 is plane, the one side that step disk 210 contacts with slide mass 240 is exactly inclined-plane.
