Abstract

The utility model discloses a dual-gear direct-current motor brake comprising a brake housing, a friction braking electromagnet, friction plates, magnetic braking electromagnets, a spring, a brake, a brake ring, a brake block, a sleeve, a single-pole three-throw switch and a direct-current power source. The brake housing is fixed on the motor enclosure through a bolt. The friction braking electromagnet, the sleeve and the brake block are fixed on the rotor shaft. The brake sleeves the sleeve. Two ends of the spring are in contact with the friction braking electromagnet and the brake separately. The brake ring and the brake housing are formed in an integrated manner. The friction plates are fixed on opposite surfaces of the brake and the brake ring. A magnetic braking electromagnet is fixed at an upper portion and a lower position of the brake block in the brake housing separately. According to the utility model, when the dual-gear direct-current motor brake is in the normal braking condition, the friction plates will not be in friction, and accordingly, the wear and tear of the brake is reduced, so the service life is prolonged. When the emergency braking is needed, the magnetic braking and friction braking are realized at the same time, and the advantage of significant braking effect can be realized.

Description

A kind of folk art term position direct current machine brake
Technical field
The utility model relates to motor braking field, relates in particular to a kind of folk art term position direct current machine brake.
Background technology
Existing direct current machine brake retardation efficiency is lower, braking force is little, and mainly by frictional force, brake and magnetic braking, frictional force braking is larger for the motor degree of wear, braking procedure heating is serious, and braking effect is poor, and magnetic braking apparatus adopts permanent magnet, make still motor to be caused to interference when motor normally moves, affect electric machine operating characteristic.
Summary of the invention
The purpose of this utility model is the deficiency for present technology, and a kind of folk art term position direct current machine brake is provided.The utlity model has dual gear, stopping power is controlled, non-in particular cases without fretting wear.
The technical solution of the utility model is as follows: a kind of folk art term position direct current machine brake, described direct current machine comprises motor case and armature spindle, and described direct current machine brake comprises brake shell, friction catch electromagnet, friction plate, magnetic braking electromagnet, spring, brake, braking ring, brake block, sleeve, cutter three throw switches and a DC power supply, wherein, described brake shell is bolted on motor case, friction catch electromagnet, sleeve and brake block are fixed on armature spindle, brake is socketed on sleeve, the groove of brake central through hole matches with the projection on sleeve, brake can not be rotated, can only do axial motion along axle, the two ends of spring contact with brake with friction catch electromagnet respectively, braking ring and brake shell are integrally formed, on the brake face relative with braking ring, be all fixed with friction plate, each fixes a magnetic braking electromagnet position, above and below of the inherent brake block of brake shell, described DC power supply separately for friction catch electromagnet is powered, or is separately the power supply of magnetic braking electromagnet by cutter three throw switches, or be that friction catch electromagnet and magnetic braking electromagnet are powered simultaneously.
The beneficial effects of the utility model are, folk art term of the present utility model position direct current machine brake is when normal brake application, and friction plate can not rub, and has reduced the loss of brake, has extended useful life.When needs brake hard, realize magnetic braking and frictional force braking simultaneously, braking effect is remarkable.The utility model is adapted to different braking occasions.

Fig. 2 is the left view of Fig. 1;
Fig. 3 is the A-A cutaway view of Fig. 1;
Fig. 4 is the utility model folk art term position commutation circuit figure;
In figure, brake shell 1, bolt 2, friction catch electromagnet 3, friction plate 4, magnetic braking electromagnet 5, armature spindle 6, spring 7, brake 8, braking ring 9, brake block 10, sleeve 11, motor case 12, cutter three throw switches 13, DC power supply 14.
Embodiment
As Figure 1-4, the utility model provides a kind of folk art term position direct current machine brake, described direct current machine comprises motor case 12 and armature spindle 6, and described direct current machine brake comprises brake shell 1, friction catch electromagnet 3, friction plate 4, magnetic braking electromagnet 5, spring 7, brake 8, braking ring 9, brake block 10, sleeve 11, cutter three throw switches 13 and a DC power supply 14, wherein, described brake shell 1 is fixed on motor case 12 by bolt 2, friction catch electromagnet 3, sleeve 11 and brake block 10 are fixed on armature spindle 6, brake 8 is socketed on sleeve 11, as shown in Figure 3, the groove of brake 8 central through holes matches with the projection on sleeve 11, brake 8 can not be rotated, can only do axial motion along axle, the two ends of spring 7 contact with brake 8 with friction catch electromagnet 3 respectively, braking ring 9 is integrally formed with brake shell 1, on brake 8 face relative with braking ring 9, be all fixed with friction plate 4, each fixes a magnetic braking electromagnet 5 position, above and below of the inherent brake block 10 of brake shell 1, described DC power supply 14 is separately 3 power supplies of friction catch electromagnet by cutter three throw switches 13, or is separately 5 power supplies of magnetic braking electromagnet, or is friction catch electromagnet 3 and 5 power supplies of magnetic braking electromagnet simultaneously.
Described brake 8 and brake block 10 are made by pure iron.
The course of work of the present utility model is as follows:
When motor is normally worked, DC power supply 14 is 3 power supplies of friction catch electromagnet, the suction that friction catch electromagnet 3 produces brake 11, and the friction plate 4 on brake 8 is separated with the friction plate 4 on braking ring 9; And not energising of magnetic braking electromagnet 5, does not produce the magnetic field force of braking action, armature spindle 6 normal rotation to brake block 10.
When motor is braked under normal circumstances, DC power supply 14 is friction catch electromagnet 3 and 5 power supplies of magnetic braking electromagnet simultaneously, friction catch electromagnet 3 is not to 6 braking actions of armature spindle, as shown in Figure 2, after 5 energisings of magnetic braking electromagnet, brake block 10 is produced to attraction, play armature spindle 6 effect of braking rapidly.In this case, two friction plates 4 can not rub, and have reduced the loss of brake, have extended useful life.
When motor is in case of emergency braked, DC power supply 14 is 5 power supplies of magnetic braking electromagnet, after 3 power-off of friction catch electromagnet, the attraction of brake 8 is eliminated, under the effect of spring 7, brake 8 moves axially along sleeve 11, two friction plates 4 are contacted, produce drag friction power, play braking effect.After 5 energisings of magnetic braking electromagnet, brake block 10 is produced to attraction, play armature spindle 6 effect of braking rapidly.In this situation, superposeed magnetic braking and frictional force braking, in case of emergency braking effect is remarkable.
