Background technology
Permanent magnet mechanism mechanical type manual separating brake method has two kinds at present: a kind of is that magnet short-cut path method, another kind are mechanical afterburning methods; Chinese patent: ZL02205189.9 discloses a kind of magnet short-cut path method separating brake method, but there is certain defective in this method, have very little air gap between magnet short-cut path dish and the outer yoke, owing to do not use for a long time after the friction, reasons such as the oxidation of air cause and generate Fe in the air gap
3O
4In case, use magnet short-cut path dish manual brake separating, between magnet short-cut path dish and the outer yoke just because Fe
3O
4Produce frictional resistance and the phenomenon that gets stuck, this shortcoming will cause can not separating brake or influence opening velocity; The problems referred to above that the afterburning method of machinery does not exist magnet short-cut path method separating brake method to exist, roughly have following several now: crank mechanism, screw thread lifting etc., Chinese patent: ZL200410002126.9 has adopted a kind of manual switching-off device of double eccentric wheel structure, this device solves the problem of fulcrum symmetrical balance of power, avoided the unbalance loading of power, overcome the problem of moving iron core disalignment, but this apparatus structure complexity, volume are big, need externally applied forces very big during manual brake separating, install and use all inconveniences; Chinese patent: ZL200520003440.9 has adopted a kind of single eccentric wheel structure, and this apparatus structure is simple, volume is little, can be applicable to the various application scenarios that position and bulk are narrow, but this device exists the fulcrum of power asymmetric, the unbalance loading that occurs power easily causes machinery to sprain.
Summary of the invention
The present invention overcomes the defective that prior art exists, purpose is to provide a kind of external mechanical manual brake-separating device of permanent magnetic mechanism, this device pierces into cam in the separating brake cover, rotating cam jack-up separating brake cover drives moving iron core guide rod and moves upward, this Design of device makes single cam move on the axial line of iron core at the application point of the Rolling bearing of separating brake cover, guarantee of the direction coincidence of the direction of separating brake power with the axial line of moving iron core, the unbalance loading that has solved owing to power causes the shortcoming that moving iron core resistance increases and machinery is sprained, Rolling bearing by on the axis of rolling, setting up again, make cam become rolling friction by sliding friction with the friction between the axis of rolling, reduced resistance, and utilize the gravity of mechanical separating brake poke rod to produce a moment that is rotated counterclockwise, the existence of this moment makes cam be rotated counterclockwise, guarantee that this device also can be returned to original position even without back-moving spring behind separating brake, solved problems of the prior art.
The present invention achieves the above object by the following technical programs: a kind of external mechanical manual brake-separating device of permanent magnetic mechanism, comprise a permanent magnet mechanism housing, in the permanent magnet mechanism housing, be provided with moving iron core and closing coil, in moving core ends moving iron core guide rod is installed, be set with supporting bracket at moving iron core guide rod exit, on supporting bracket, be provided with a separating brake cover, center at the separating brake cover offers a groove, overlap remaining solid cylinder center at separating brake and be provided with a through hole, the perisporium of through hole is provided with the internal thread that is threaded with moving iron core guide rod, the separating brake set upper side is provided with through hole, and separating brake is enclosed within right-hand member and also is provided with an opening; The separating brake cover fuses by screw thread and moving iron core guide rod, the axis of rolling is located in the separating brake cover by through hole, split washer is located at the two ends of the axis of rolling, Rolling bearing is set on the axis of rolling, and cam is located at machinery and divides on the brake connection rod, and cam divides brake connection rod to be threaded with machinery, and it is fastening with gland nut, cam pierces in the groove of separating brake cover by opening, and the bearing pedestal supported mechanical that is installed on the supporting bracket is divided brake connection rod, and brake connection rod is vertical is connected by screw thread and machinery branch for mechanical separating brake poke rod.
Beneficial effect of the present invention: 1) this device has adopted the separating brake cover, makes the application point of separating brake external force of cam act on the center line of moving iron core, and the moment of resistance reduces like this, and machinery is sprained and reduced, main force's arm minimum, and externally applied forces can reach minimum.
2) this device has installed axle sleeve additional on the axis of rolling, makes original sliding friction change rolling friction into, has reduced resistance.
3) the center of gravity effect of mechanical separating brake poke rod for cam has transmitted a moment that is rotated counterclockwise, makes resetting of cam need not adopt returning spring.
Adopt that the required separating brake external force of the external mechanical manual brake-separating device of permanent magnetic mechanism of this apparatus structure is little, simple in structure, volume is little, be convenient to operation, applied widely, reliable operation.
