Abstract
The utility model discloses a direct current short-stroke electromagnetic brake, which comprises a spring adjusting device, a recoil adjuster and a base, and is characterized by further comprising a drive mechanism and an electromagnetic mechanism, wherein the electromagnetic mechanism comprises two groups of electromagnetic coils which are respectively installed on a fixed iron core which is movably hinged with the base, the drive mechanism comprises two groups of brake shoes, a short brake arm, a long brake arm and a connecting bar, wherein the two groups of the brake shoes are respectively fixed with the long brake arm and the short brake arm, the lower end of the long brake arm and the middle portion of the short brake arm are respectively connected with the base, one end of the connecting bar is connected with the long brake arm, and the other end thereof is movably connected with the free end of the short brake arm. When the electromagnetic coils are electrified, a moving iron core is absorbed to deflect leftwards, a left brake shoe is separated from a brake wheel, and a right brake shoe is driven to separate from the brake wheel, thereby opening the brake, whereas, when the electromagnetic coils are cut off, the long brake arm are pushed to deflect rightward by a brake spring, thereby realizing the contracting brake. The direct current short-stroke electromagnetic brake has the characteristics of simple structure and quick movement.
Description
Technical field
The utility model relates to the break that contains electromagnet, relates in particular to direct current short stroke electromagnetic brake.
Background technique
At present, the domestic and international dc electromagnetic brake of producing, its structural type is basic identical, as MW type, ZWZ type etc.Electromagnetic mechanism adopts the form of unicoil, singlecore, that driving mechanism adopts is the frame form, do not dispose brake shoe and move back apart from device, this is that their common structural features have also constituted their common intrinsic shortcomings: promptly the consumptive material height, move back apart from big, movement speed slow and complex structure.
Summary of the invention
Goal of the invention of the present utility model is to overcome targetedly above-mentioned shortcoming and has proposed a kind of direct current short stroke electromagnetic braking apparatus that adopts the electromagnetic structure of twin coil, two iron cores and have connecting rod type transmission mechanism.
Technical solution of the present utility model is achieved in that
A kind of direct current short stroke electromagnetic brake, comprise that spring adjusting device, brake shoe move back apart from regulator and base, is characterized in that: also comprise driving mechanism and electromagnetic mechanism, wherein said electromagnetic mechanism comprises two groups of electromagnetic coils, be contained in respectively on the fixed core, fixed core then is movably hinged with base; Described driving mechanism comprises two groups of brake shoe, short brake arm, long brake arm and connecting rod, and two groups of brake shoe are wherein fixedlyed connected with long brake arm and short brake arm respectively, and the intermediate portion of the lower end of long brake arm and short brake arm is connected with base respectively; Described connecting rod one end is connected in long brake arm, and its other end then flexibly connects with the free end of lacking brake arm.
Described spring adjusting device comprises brake spring and adjusting nut, is fixed between fixed core and the long brake arm by bolt and fastening nut.
Described brake shoe moves back apart from regulating device to be made up of adjusting screw, nut and spacer.
Compared with prior art, the utility model has the advantages that conspicuously, mainly show:
1, because electromagnetic mechanism adopts the structural type of two iron cores, twin coil, under the prerequisite of safety action ampere-turn, copper consumption is 1/2nd of an existing product only, even reduces to 1/3rd.
2, owing to adopt special electromagnetic mechanism, driving mechanism, make the stroke of electromagnet only be 1/2nd of traditional electrical magnet, reduce energy consumption.
3, owing to adopt special electromagnetic mechanism, driving mechanism, the stroke that makes electromagnet only is 1/2nd (stroke of traditional electrical magnet should equal the summation that two brake shoe move back distance) that two brake shoe move back distance, improved brakeage speed thus, particularly reduce period of braking, improved reliability.
4, since driving mechanism itself just guaranteed that brake shoe moves back the equilibrium of distance, cancelled traditional balanced part, make simple in structurely, it is convenient especially to keep in repair.
5, because simple in structure, the complete machine component are few, reduced complete machine weight, reduced manufacture cost.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Among the figure: 1, electromagnetic coil, 2, moving unshakable in one's determination, 3, fixed core, 4, spring adjusting device, 5, brake spring, 6, electromagnetic mechanism, 7, Brake drum, 8, brake shoe, 9, short brake arm, 10, driving mechanism, 11, brake shoe regulator, 12, connecting rod, 13, base, 14, long brake arm.
Embodiment
As shown in Figure 1.Direct current short stroke electromagnetic brake described in the utility model, by the electromagnetic mechanism 6 two unshakable in one's determination that comprises two groups of electromagnetic coils 1, fixed core 2, moving unshakable in one's determination 3, base 13, by long brake arm 14, lack brake arm 9, base 13, connecting rod 12, two groups of driving mechanisms that brake shoe regulator 11 is formed 10, brake shoe 8, brake spring 5 and spring adjusting device 4 five major parts constitute, wherein said electromagnetic coil 1 is contained in respectively on the fixed core 3, and 3 of fixed cores and base 13 are movably hinged; Described two groups of brake shoe 8 are fixedlyed connected with long brake arm 14 and short brake arm 9 respectively, and the intermediate portion of the lower end of long brake arm 14 and short brake arm 9 is connected with base 13 respectively; One end of described connecting rod 12 is connected in long brake arm 14, and its other end then flexibly connects with the free end of lacking brake arm 9;
Described spring adjusting device comprises brake spring 5 and adjusting nut, is fixed between fixed core 3 and the long brake arm 14 by bolt and fastening nut;
Described brake shoe moves back apart from regulating device to be made up of adjusting screw, nut and spacer.
This brakeage process is: because fixed core 3 is fixedlyed connected with the screw rod of spring adjusting device 4 and the screw rod of brake shoe regulator, when electromagnetic coil is switched on, moving unshakable in one's determination 3 are attracted and drive the deflection left of long brake arm 14, left side brake shoe leaves Brake drum 7, make right brake shoe leave Brake drum 7 by the short brake arm 9 of connecting rod 12 pullings simultaneously, so far finished (opening a sluice gate) process of opening of break.Then make the deflection to the right fast of long brake arm during outage, rapidly braking (band-type brake) by brake spring.
