Abstract
The utility model provides a bidirectional positioning device for servo submersible motor rotor magnetic steel. The bidirectional positioning device comprises a plurality of magnetic steel axially sleeved and adhered to a rotor iron core and is characterized in that keys are disposed on the outer wall of the rotor iron core, a magnetic steel pressing ring is disposed at a butt joint of each two adjacent magnetic steel, and magnet insulating end rings are disposed at the outer ends of magnetic steel at two ends. By coordination of the magnet insulating end rings and magnetic steel pressing rings, magnetic steel can be fixed axially. Magnetic steel radial rotation can be prevented by the keys disposed on the outer wall of the rotor iron core. Reliable axial and radial positioning of magnetic steel is guaranteed by means of mechanical fixation, and accordingly the service life of a motor is unaffected by magnetic steel falling. In addition, the bidirectional positioning device is good in working performance.
Description
Technical field
The utility model provides a kind of servo submersible motor rotor magnetic steel two-way positioner, belongs to the servomotor technical field.
Background technology
Current servo submersible electric machine with oil rotor magnetic steel is many to be fixed on the armature spindle in bonding mode.Because the condition of work of servo submersible motor is abominable relatively, and it is more to influence the factor of adhesive strength, so adhesive effect is relatively poor, magnet steel often has obscission, influences the useful life of motor.
The utility model content
The purpose of this utility model provides a kind of two-way positioner of servo submersible motor rotor magnetic steel that can overcome above-mentioned shortcoming, long service life, excellent working performance.Its technical scheme is:
The two-way positioner of a kind of servo submersible motor rotor magnetic steel, comprise suit vertically and be bonded in polylith magnet steel in the rotor core, it is characterized in that: the outer wall of rotor core is provided with key, the joint of adjacent magnet steel is provided with the magnet steel trim ring, is provided with every the magnetic end ring in the outer end of the magnet steel that is positioned at two ends.
The utility model compared with prior art has following advantage: the joint of adjacent magnet steel is provided with the magnet steel trim ring, and sets up every the magnetic end ring in the outer end of the magnet steel that is positioned at two ends, cooperates with the magnet steel trim ring and can carry out axial restraint to magnet steel every the magnetic end ring; The bond energy that arranges on the rotor core outer wall prevents that magnet steel from radially rotating.With the mode of mechanical fixation guarantee magnet steel axially, radially reliable location, make motor can not influence its useful life because magnet steel comes off.
Description of drawings
Fig. 1 is the structural representation of the utility model embodiment.
Among the figure: 1, every magnetic end ring 2, magnet steel 3, magnet steel trim ring 4, rotor core 5, armature spindle 6, key
Embodiment
