Description
Technical field
The utility model relates to dynamo-electric field, specifically, relates to a kind of adjustable force moment electromagnetic braking motor.
Background technology
The various forms of motor that use can not solve motor in application with mechanical mode at present, directly determine the size of electric-motor drive moment by the motor interior scalable; When the super moment of electromotor overload, motor can't carry running by force, and the super moment separation and reunion device that plays required setting in effective protection of motor or the plant equipment transmission need not to install additional separately, just can finish by motor.
The utility model content
The purpose of this utility model provides a kind of adjustable force moment electromagnetic braking motor.
In order to realize the purpose of this utility model, the utility model provides a kind of adjustable force moment electromagnetic braking motor, comprises electric-motor drive part, adjustable force moment part and electromagnetic braking part.Wherein, electric-motor drive partly comprises: motor casing, stator, rotor, hollow sleeve, end cap, blade cover, fan blade, bearing, connecting bolt, output shaft.
Adjustable force moment partly comprises: moment brake disc, drive plate, fastening bolt, disk spring, locking nut, trundle.
Electromagnetic braking partly comprises: electromagnetic brake, electromagnet armature, bolt, frictional disk.
The electric-motor drive part, the stator of motor by common way be pressed in the motor housing, armature spindle adopts open-core type, rotor combines with hollow sleeve, drive hollow sleeve and be fastened on the drive plate of hollow sleeve end face by rotor rotation, be subjected to combining the motor power transmission of disk spring pressure with moment brake disc on output shaft to output shaft by drive plate.
The adjustable force moment part: output shaft bears the size of torsional moment, adjust by the locking nut on the output shaft that size decides in the hand of spinning disk spring, when the stressed moment of torsion of output shaft greater than the good moment of adjusted, the moment brake disc can be thrown off slip with stressed the combination just of drive plate, and motor does not carry the effect that the super moment separation and reunion of overload is played in running.
The electromagnetic braking part: motor is in when running, and electromagnetic brake is the electromagnet armature adhesive, and frictional disk is in the both ends of the surface loosening state that do not stress, and drives frictional disk by the trundle on the drive plate simultaneously and rotates with drive plate.
During the motor brake brake, electromagnetic brake discharges electromagnet armature, by the electromagnet armature of exerting pressure of the spring pressure on the electromagnetic brake frictional disk is braked, shut down at once after drive plate makes the motor shutdown by braking force not being transmitted simultaneously at the trundle on the frictional disk.
The beneficial effects of the utility model are: finish in motor interior with mechanical mode.
1, set the size of electric-motor drive moment arbitrarily, during the super moment of electromotor overload, motor can not carry running by force, and motor can not burnt out because of overload, plays motor is effectively protected.
2, be applied in the super moment separation and reunion device that needs setting in the machine driving, need not to install additional separately directly and just can finish by motor.

Embodiment
Following examples are used to illustrate the utility model, but are not used for limiting scope of the present utility model.
The electric-motor drive mode: the stator of motor is pressed into motor housing 7 inner rotor shafts and adopts open-core type, hollow sleeve 21 cylindricals are combined with rotor 9 endoporus, bearings at both ends 622 supports hollow sleeve 21, hollow sleeve plays the effect of armature spindle, rotor 9 rotations drive hollow sleeve 21 runnings, drive plate 19 usefulness fastening bolts 20 are fastened on the axial end of hollow sleeve 21, hollow sleeve 21 and drive plate 19 run-in synchronisms, make by the locking nut 14 spinning disk springs 15 on output shaft 13 axle heads in hollow sleeve 21 endoporus that moment brake disc 6 is stressed to be combined (drive plate 19 outer faces speckle with friction plate) motor is passed to output shaft 13 with drive plate 19 end-face frictions, drive the mechanical driving part running of joining by output shaft 13.
Adjustable force moment mode: make disk spring 15 pressurizeds combine the size that stressed size (bear the moment scope according to motor and select required moment) is determined motor moment with drive plate 19 end-face frictions with moment brake disc 16 by the locking nut of adjusting on the output shaft 13 14; When the stressed moment that combines greater than the good 19 meters wipings of moment brake disc 16 and drive plate of adjusted of output shaft 13, moment brake disc 16 contacts end face and the not preceding state of friction slip occurs with drive plate 19, motor does not carry running, the overload of motor is played the effect of super moment separation and reunion.
The electromagnetic braking mode: frictional disk 17 both ends of the surface speckle with friction plate, outer face and electromagnet armature 4 contact frictions, inner face and the contact friction of motor rear end face.During motor operation, electromagnetic brake 3 is in "on" position, with electromagnet armature 4 adhesives, compresses the spring on the electromagnetic brake 3 simultaneously; At this moment, frictional disk 17 is in two ends and the loosening state that do not stress (staying certain braking gap).Driving frictional disk 17 by the trundle on the drive plate 9 rotates with drive plate.When motor is shut down braking brake; electromagnetic brake 3 is in off-position; electromagnet armature 4 is discharged; spring on the electromagnetic brake 3 discharges simultaneously; make electromagnet armature 4 end faces and frictional disk 17 outer faces; the inner face of frictional disk 17 and motor housing 7 rear end faces are braked by the spring release force mutually, and simultaneously frictional disk 17 will brake by the not other trundle 18 on frictional disk 17 and pass to drive plate 19 in the hand, shut down at once after motor is cut off the power supply.
More than be preferred forms of the present utility model, some identical, replacement schemes that those of ordinary skill in the art can expect apparently according to content disclosed by the invention all should fall into the scope that the utility model is protected.
