Abstract
A low-noise motor brake comprises a brake disc, an armature, a magnet yoke, a spline housing and a hand releasing device. The spline housing is used for being connected with a motor shaft, and the hand releasing device is in transmission connection with the brake disc. The brake disc, the armature and the magnetic yoke are sequentially arranged in a coaxial mode from front to back, the control disc is meshed with the spline housing through a spline, a spring is arranged between the armature and the magnetic yoke, an electromagnetic coil is arranged on the magnetic yoke, and a rubber ring is arranged between the brake disc and the spline housing. The low-noise motor brake is simple in structure and convenient to use. The rubber ring is arranged between the brake disc and the spline housing, so that noise produced during braking is reduced. Meanwhile, the brake releasing state of the brake can be maintained, force moment of a brake handle is short, and the low-noise motor brake saves more labor and is more convenient.
Description
Technical field
The utility model relates to motor, relates in particular to a kind of low noise motor break.
Background technique
Electromotor brake is the break of a kind of electromagnetism adhesive of switching on, power-off friction catch formula, threephase asynchronous for electromagnetic brake type, be widely used in the machineries such as metallurgy, chemical industry, food, lathe, packing, realize and to stop fast and accurate location, the occasion such as safety brake while can be used on power-off.Traditional electromotor brake noise when braking is larger.
Summary of the invention
Based on this, for above-mentioned technical problem, provide a kind of low noise motor break.
For solving the problems of the technologies described above, the utility model adopts following technological scheme:
A kind of low noise motor break, comprise brake disc, armature, yoke, for connecting the spline housing of motor shaft and the hand release being in transmission connection with described brake disc, described brake disc, armature and yoke arrange from front to back successively with one heart, described brake disc and described spline housing pass through spline engagement, between described armature and yoke, be provided with spring, described yoke is provided with electromagnetic coil, is provided with a circle rubber ring between described brake disc and spline housing.
The straight way that the rear side of described yoke has chute and the footpath that is connected with this chute extends internally, the external diameter of described chute reduces from front to back gradually;
Described hand release comprises release board, sliding pearl and brake handle, described release board is positioned at the rear side of described yoke with one heart, described release board is in transmission connection by screw and the described brake disc through described yoke and armature, on described release board, there is the L shaped release arm that stretches out along described straight way footpath and be placed on described chute top, described release arm and described chute and straight way surround and form a slideway, and described release arm is provided with a radially tapped through hole that is positioned at described chute top, described sliding pearl is located in described slideway, the head of described brake handle is threaded with described tapped through hole, and this head has the screw thread of being longer than described tapped through hole length.
Described release board is rounded.
The profile of described release board is greater than the arc-shaped edges of semi-circle and a straight flange by one and surrounds and form, and described release arm is positioned at the top of described arc-shaped edges.
Described armature and brake disc are provided with a circle dirt-proof boot outward.
The utility model is simple in structure, easy to use, by rubber ring being set between brake disc and spline housing, the noise having produced while having reduced braking, and when maintenance has a power failure, the moving brake handle of layback drives release board to be subjected to displacement to rear side backward, and then can drive brake disc to leave motor end face, braking is removed, simultaneously, brake handle is screwed in above-mentioned slideway from tapped through hole, sliding pearl in slideway is moved in slideway, sliding pearl is snapped in straight way, make break maintain braking relieving state, without manpower, continue to force in brake handle, and the moment of brake handle is shorter, more laborsaving convenience.
Accompanying drawing explanation
Below in conjunction with the drawings and specific embodiments the utility model, be elaborated:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model one embodiment's side-looking structural representation;
Fig. 3 is another embodiment's of the utility model side-looking structural representation.
Embodiment
As Figure 1-3, a kind of low noise motor break, comprises brake disc 1100, armature 1200, yoke 1300, spline housing 1400 and hand release 1500.
Wherein, brake disc 1100 by and motor end face between produce frictional force and pass to motor shaft by spline housing 1400 and make motor braking.
Outside armature 1200 and brake disc 1100, be provided with a circle dirt-proof boot 1999, can prevent that dust from entering.
The straight way 1320 that the rear side of yoke 1300 has chute 1310 and the footpath that is connected with this chute 1310 extends internally, the external diameter of chute 1310 reduces from front to back gradually.
When the electromagnetic coil 1700 in yoke 1300 is switched on, under the effect of electromagnetic force, armature 1200 is attracted to yoke 1300, and brake disc 1100 is released, and in releasing state, meanwhile, spring 1600 is pushed in compressive state by armature 1200.
When motor breaks down power-off, electromagnetic coil 1700 dead electricity, armature 1200, no longer by magnetic attraction, under the restoring force effect of spring 1600, makes armature 1200 tops to brake disc 1100, makes motor braking.
When maintenance has a power failure, can carry out manual release by hand release 1500, braking is removed.
Particularly, the moving brake handle 1530 of layback drives release board 1510 to be subjected to displacement to rear side backward, and then can drive brake disc 1100 to leave motor end face, and braking is removed.
, brake handle 1530 is screwed in above-mentioned slideway from tapped through hole 1511a meanwhile, the sliding pearl 1520 in slideway is moved in slideway, sliding pearl 1520 is snapped in straight way 1320, break maintains braking relieving state, without manpower, continues to force in brake handle 1530, laborsaving convenience.
Be understandable that, as shown in Figure 2, the profile of release board 1510 can be circle, also can be greater than the arc-shaped edges of semi-circle and a straight flange by one surrounds and forms, see Fig. 3, now, release arm 1511 is positioned at the top of arc-shaped edges, so the moment of brake handle 1530 when pulling has been shortened in design, more laborsaving.
But, those of ordinary skill in the art will be appreciated that, above embodiment is only for the utility model is described, and be not used as restriction of the present utility model, as long as within the scope of connotation of the present utility model, to the above embodiment's variation, modification, all will drop within the scope of claims of the present utility model.
