The utility model is realized by following technology:
A kind of elevator brake, it is characterized in that: comprise friction lining, armature, main spring, set screw, electromagnet, the line bag, backstopping device, dowel bolt and drg enclosing cover are installed, be provided with the friction lining that is enclosed within on the motor shaft in electric motor end cap one side, described backstopping device is by steel ball, jump ring, the backstopping device spring, the backstopping device inclined-plane, connecting dowel bolt and backstopping device gland forms, described armature, be connected with the backstopping device gland to be enclosed within and connect on the dowel bolt in the backstopping device inclined-plane, the little side of opening at the internal taper hole on backstopping device inclined-plane is provided with steel ball, opposite side is provided with jump ring, is provided with the backstopping device spring between jump ring and steel ball; Be provided with the adjustment screw between armature and drg enclosing cover, main spring is located at friction lining and adjusts between the screw; Electric motor end cap, armature, electromagnet and drg enclosing cover are enclosed within successively to be installed on the dowel bolt, at connection dowel bolt cover auxiliary spring is arranged.
Described main spring and adjustment screw are more than 3, are evenly distributed in outside the drg take motor shaft as the axle center to cover; Described connection dowel bolt and auxiliary spring are more than 3, are evenly distributed on the backstopping device gland take motor shaft as the axle center; It is more than 3 that dowel bolt is installed, and is evenly distributed in outside the drg take motor shaft as the axle center to cover.
The beneficial effects of the utility model are: the wearing clearance auto-compensation of this elevator brake, armature and electromagnet gap remain constant, thereby so that drg does not need to carry out frequently gap adjustment, thereby can improve work efficiency, the maintenance workload of minimizing equipment, also reduce possible fault or the damage accident that careless mistake causes of thinking, improved safety.This elevator brake in use can reduce the maintenance maintenance expense, has the advantages such as scientific structure design is reasonable, good in economic efficiency, can be widely used in having good marketing prospect in the machine driven system of the industries such as lifting, building.
Description of drawings
Below in conjunction with accompanying drawing the utility model is further described.
Accompanying drawing 1 is the structural representation of the utility model elevator brake;
1 motor shaft, 2 electric motor end caps, 3 friction linings, 4 armature, 5 main springs, 6 line bags, 7 electromagnet, 8 adjust screw, 9 drg enclosing covers, 10 connect dowel bolt, 11 backstopping device glands, 12 jump rings, 13 backstopping device springs, 14 steel balls, 15 install dowel bolt, 16 auxiliary springs, 17 backstopping device inclined-planes.
The specific embodiment
Below in conjunction with accompanying drawing and the specific embodiment, the utility model is described further.Accompanying drawing is a kind of specific embodiment of the present utility model.This embodiment is a kind of elevator brake, it is characterized in that: comprise friction lining 3, armature 4, main spring 5, set screw 8, electromagnet 7, line bag 6, backstopping device, dowel bolt 15 and drg enclosing cover 9 are installed, be provided with the friction lining 3 that is enclosed within on the motor shaft in electric motor end cap one side, described backstopping device is by steel ball 14, jump ring 12, backstopping device spring 13, backstopping device inclined-plane 17, connect dowel bolt 10 and backstopping device gland 11 compositions, described armature 4, are connected with the backstopping device gland to be enclosed within successively and connect on the dowel bolt 10 in backstopping device inclined-plane 17, the little side of opening at the internal taper hole on backstopping device inclined-plane 17 is provided with steel ball 14, opposite side is provided with jump ring 12, is provided with backstopping device spring 13 between jump ring 12 and steel ball 14; Be provided with between armature 4 and drg enclosing cover 9 and adjust screw 8, main spring 5 is located at friction lining 3 and adjusts between the screw 8; Electric motor end cap 2, armature 4, electromagnet 7 and drg enclosing cover 9 are enclosed within successively to be installed on the dowel bolt 15, at connection dowel bolt 10 covers auxiliary spring 16 is arranged.Described main spring 5 and adjustment screw 8 are more than 3, are evenly distributed on the drg enclosing cover 9 take motor shaft as the axle center; Described connection dowel bolt 10 and auxiliary spring 16 are more than 3, are evenly distributed on the backstopping device gland 11 take motor shaft as the axle center; It is more than 3 that dowel bolt 15 is installed, and is evenly distributed on the drg enclosing cover 9 take motor shaft as the axle center.
Its principle of work of this electromotor brake:
1) braking mode (dead electricity): armature 4 pressing friction sheet 3 under main spring 5 effects is realized braking, and while backstopping device gland 11 passes through to connect dowel bolt 10 and armature 4 compresses steel ball 14, and backstopping device is in disengaged condition.
2) (give electricity) during motor rotation: armature 4 under electromagnet 7 effects, make backstopping device gland 11 move to right simultaneously by the bolt 10 that is located by connecting steel ball 14 moves to right in spring 13 effects, backstopping device inclined-plane 17 chuckings prevent that electromagnet 7 from moving to left.
3) auto-compensation: because braking mode electromagnet 7 dead electricity, armature 4 is strained backstopping device glands 11 by connecting dowel bolt 10 under auxiliary spring 16 effects, steel ball 14 is moved to left, backstopping device is in disengaged condition, electromagnet 7 and armature 4 are in pressing friction sheet 3 states that move to left together under main spring 5 effects, so can realize auto-compensation.
The wearing clearance auto-compensation of elevator brake of the present utility model, armature 4 remains constant with electromagnet 7 gaps, thereby so that drg does not need to carry out frequently gap adjustment, thereby can improve work efficiency, the maintenance workload of minimizing equipment, also reduce possible fault or the damage accident that careless mistake causes of thinking, improved safety.This elevator brake in use can reduce the maintenance maintenance expense, has the advantages such as scientific structure design is reasonable, good in economic efficiency, can be widely used in having good marketing prospect in the machine driven system of the industries such as lifting, building.
