Abstract
The utility model discloses a silent type dead electromagnet brake, which comprises a magnetic yoke; an annular groove, a plurality of spring grooves and grooves used for placing elastic cushions are formed on the end surface of the magnetic yoke; a coil is installed in the annular groove; springs are arranged in the spring grooves, and elastic cushions are arranged in the grooves; a brake disc component with a shaft hole in the middle is further included, a raised circular sleeve is arranged in the middle of the brake disc component, and an armature and a magnetic yoke are sequentially nested outside the circular sleeve; the springs and the elastic cushions are pushed against on the end surface of the magnetic yoke; a hollow bolt is mounted on the magnetic yoke, a screw cap part of the hollow bolt is retained on the brake disc component; the polished rod section of the hollow bolt penetrates through the magnet armature, and an opening on the brake disc component; and the threads of the hollow bolt are screwed with the magnetic yoke; and a flat washer is arranged between the brake disc component and the magnet armature, and the flat washer is nested outside the hollow bolt. Due to adoption of the elastic cushions, the utility model can easily achieve silence than using a spring to push against the magnet armature, moment of force can not loss; therefore, the silent type dead electromagnet brake has the advantage that the braking torque is not affected while noises are eliminated.
Description
Technical field:
The utility model relates generally to a kind of break, relates in particular to a kind of squelch type power-off brake.
Background technique:
Power-off brake is used for having a power failure anti-dangerous more, occasions such as accurate location, and it mainly is made up of parts such as yoke, armature, spring, coil and brake disc assemblies.Power-off brake is when coil electricity, and yoke generation magnetic field adhesive armature overcomes spring force friction disk is opened brake off, and magnetic field disappearance spring is pushed armature open and pushed down the purpose that brake disc generation frictional force reaches braking during outage.When armature closure and disconnection, armature and friction disk have significantly Strike note.But in a lot of occasions, very high to the requirement of noise, as lamp stand jacking equipment in stage equipment, the stadiums etc., tangible noise can not be arranged.
The model utility content:
The utility model purpose is exactly in order to remedy the defective of prior art, a kind of squelch type power-off brake that can not produce obvious noise to be provided.
The utility model is achieved through the following technical solutions:
The squelch type power-off brake includes yoke, it is characterized in that: described yoke end face is provided with circular groove, several spring grooves and places the groove of cushion, and coil is installed in the circular groove, is provided with spring in the spring groove, is provided with cushion in the groove;
Comprise that there is the brake disc assembly of axis hole in central authorities, there is the ring set of protrusion at described brake disc assembly middle part, and described ring set is set with armature and yoke outward successively; Described spring, cushion withstand on described yoke end face;
On the described yoke hollow bolt is installed, the nut of described hollow bolt partly keeps off on brake disc assembly, and the polished rod section of hollow bolt is passed the perforate on armature, the brake disc assembly, and the screw thread and the yoke of hollow bolt screw; Be provided with plain washer between described brake disc assembly and the armature, described plain washer is enclosed within outside the hollow bolt;
On the described yoke screw rod is installed, described screw rod passes the mesopore of hollow bolt, and reaches the outside thread that is partly with in the brake disc assembly outside.
The utility model installs a plurality of O type circles additional on the installation hollow bolt, separate with plain cushion between each O type circle, formed an elastomer that can stretch, withstand armature, realized the buffering of armature in movement process, owing to be a plurality of O type circles and washer combinations, the strength of buffering can increase and decrease O type circle to be adjusted, to reach quiet purpose fully.
The utility model is when coil electricity, and yoke generation magnetic field adhesive armature overcomes spring force friction disk is opened brake off, because yoke and armature residual gap are provided with cushion, the utility model can not produce noise when brake off; During coil blackout, magnetic field disappears, spring is pushed armature open and is pushed down the purpose that brake disc generation frictional force reaches braking, because be provided with the elastomer of the O type circle peace packing ring composition that installs additional by hollow bolt between armature and the brake disc assembly, elastomer has slowed down armature and has been promoted the travelling speed that produces by spring.So when the utility model can not make a noise when braking yet.
The utility model has the advantages that:
The utility model uses cushion than to use spring and withstand the easier realization of armature quiet and don't can lose moment, because the elastomer that O type circle peace packing ring is formed is than the easier adjusting elastic force of spring.Therefore the utlity model has the advantage that when abating the noise, does not influence braking torque.
Description of drawings:
Accompanying drawing is a structural representation of the present utility model.
Embodiment:
The squelch type power-off brake includes yoke 1, and described yoke 1 end face is provided with circular groove, several spring grooves and places the groove of cushion, and coil 5 is installed in the circular groove, is provided with spring 6 in the spring groove, is provided with cushion 2 in the groove;
There is the brake disc assembly 4 of axis hole in the central authorities that comprise, and there is the ring set 7 of protrusion at described brake disc assembly 4 middle parts, described ring set 7 outer armature 3 and the yokes 1 of being set with successively; Described spring 6, cushion 2 withstand on described yoke 1 end face;
On the described yoke 1 hollow bolt 8 is installed, the nut of described hollow bolt 8 partly keeps off on brake disc assembly 4, and the polished rod section of hollow bolt 8 is passed the perforate on armature 3, the brake disc assembly 4, and the screw thread of hollow bolt 8 and yoke 1 screw; Be provided with plain washer 9 between described brake disc assembly 4 and the armature 3, described plain washer 9 is enclosed within outside the hollow bolt 8;
On the described yoke 1 screw rod 10 is installed, described screw rod 10 passes the mesopore of hollow bolt 8, and reaches the outside thread that is partly with in brake disc assembly 4 outsides.
