Between outer rotor, inner stator, sun gear, planet carrier, ring gear are set in the space that is formed；Outer rotor is by bearings in master
On axle, inner stator is arranged on the inner side of outer rotor；Sun gear is arranged on main shaft and is connected with outer rotor, and planet carrier is arranged on
On main shaft in one end cap, planetary gear is connected in planet carrier, planetary gear is meshed with sun gear, and planetary gear with
Ring gear is meshed, and ring gear compression fit is connected to the inner ring of wheel hub.Arrestment mechanism is also set up on main shaft, arrestment mechanism has
Electromagnet, the first stator, friction plate, the second stator, when electromagnet dead electricity, the first stator and the second stator will rub
Pad clamps.In use for some time, friction plate is thinning, so as to influence braking effect, it is necessary to which more renewal of facing renewal, causes to rub
The service life of piece is short, changes cumbersome, increase cost.
The content of the invention
The purpose of this utility model is for overcome the deficiencies in the prior art, there is provided the adjustable motor of one kind brake,
It is adjusted after friction disc wear, does not influence braking effect.
What the purpose of this utility model was realized in：The adjustable motor of one kind brake, including main shaft, set on main shaft
Put inner stator, outer rotor and arrestment mechanism；The arrestment mechanism includes electromagnet, friction fixed board, friction plate, the dynamic plate of friction and pulled
Hand, electromagnet are arranged on the side of inner stator, and friction fixed board, friction plate and the dynamic plate of friction are arranged in the inner stator, rubbed
Between friction fixed board and the dynamic plate of friction, friction plate is connected pad with outer rotor；Spanner shield is wholely set on the spanner
Hand；Friction dynamic plate, friction plate and the friction fixed board to the side for being far successively set on electromagnet, the dynamic plate of friction by closely connecting
Push rod is connect, push rod connects armature after stretching out inner stator, and armature is connected by spring with electromagnet；The friction fixed board passes through pull bar
It is connected with inner stator；It is threaded on the main shaft at the electromagnet, spiral shell is fixed in the thread segment threaded connection yoke of main shaft
Mother, yoke fixing nut are arranged on side of the electromagnet away from the dynamic plate of friction.
Principle of the present utility model：Friction fixed board is connected by pull bar with inner stator, fixed.When electromagnet dead electricity
When, spring is pushed outwardly, so as to be moved axially with moving armature, push rod, the dynamic plate of friction to friction plate direction, to friction plate system
It is dynamic, the reed time controll operating of outer rotor for motor, implement dead electricity braking function.After using a period of time, friction plate mill
Thinning, rotation yoke fixing nut is damaged, band motor magnet, armature, push rod, the dynamic plate of friction are finely adjusted to friction plate direction, really
Braking effect is protected, without more renewal of facing renewal, the service life of friction plate is extended, has saved cost.
In order that yoke fixing nut does not increase volume, side of the electromagnet away from the dynamic plate of friction sets nut to install
Groove, yoke fixing nut are arranged in nut mounting groove.
In order to protect screw at spanner, switch etc., shield is connected on the electromagnet, the electromagnet and spanner are equal
It is arranged in shield, the spanner handguard stretches out shield.
