Description
Technical field
The present invention relates to a kind of skyscraper elevator ultrahigh speed, particularly heavy－duty traction machine, one kind be easy to assembling and
The permanent magnetic synchronous traction machine of maintenance.Belong to traction machine technical field.
Background technology
At present, due to Chinese national economy high speed development, skyscraper is continued to bring out, so consumer is to skyscraper electricity
Ladder ultrahigh speed（Normal speed is not less than 7.0m/s）, heavy－duty（Nominal load capacity is not less than 1600kg）The demand of traction machine
Improve constantly, but because technology is not mature enough, so existing skyscraper elevator ultrahigh speed, heavy－duty traction machine are also deposited
There are some defects.Such as defect of the applicant once for traction sheave and its support connection member presence is improved, and designs
Go out " ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine " of Publication No. CN101973479A, its structure recorded includes
Frame, the dual-gripper main shaft being assembled in the frame and stator line bag, be fixed on rotor block on the main shaft, traction sheave,
Disc brake apparatus, rotor set, are assembled in the parts such as the encoder of rear-end of spindle.Wherein main shaft passes through fore bearing and rear bearing branch
Between the support and front support at frame two ends, the rotor set for setting the air vent of ventilation and heat is fixed on double branch of main shaft for support
Between support, rotor block, brake disc and traction sheave is connected respectively by rotor set and be fixed together with main shaft, be integrally formed formula
Structure.Although the ultra-high-speed heavy-loading outer-rotor permanent magnet synchronous traction machine improves the stress condition and loading capacity of traction machine,
Runnability is improve, but, found in actual motion, when traction foot wheel abrasion needs repairing replacing, it is necessary to by disc type brake
The jiggering gear ring and front support of device could be changed after all pulling down.In traction machine maintenance sites, due to narrow space, if dismounting
Instrument is not complete, then because jiggering gear ring and front support are very heavy, so certain difficulty can be carried out to belt removal.During execute-in-place, once it is preceding
Support is pulled down main shaft and just loses support, because that this end suspender belt of main shaft need to be sling or be propped with backup support, is so hindered again
The removal of traction sheave, therefore some are inconvenient when safeguarding.
Additionally, in " elevator traction sheave " of the A of Publication No. CN 102849582, the structure that it is recorded includes annular
Wheel rim and located at coaxial with the wheel rim wheel cylinder in wheel rim center, is connected between the wheel rim and wheel cylinder by the annular perpendicular to axial direction
Portion is connected, and one end of the wheel rim is provided with accessory whorl circle, and accessory whorl ring outer wall is circumferentially with the grooving of radial depressions, the accessory whorl circle with
Wheel rim is split type, is connected through a screw thread connected.The knockdown wheel rim and accessory whorl circle, are convenient for changing and are applicable band grooving accessory whorl circle
Or the accessory whorl circle for damaging, need to change whole traction sheave when solving traction sheave failure, to the skill that normal work is made troubles
Art problem.But, the fixed part that each accessory whorl circle of the elevator traction sheave extends is fixed after grafting only by screw, nut,
And screw, nut contact surface are cambered surface, this connected mode is unreliable, yielding during accessory whorl circle stand under load；Accessory whorl circle extends
Fixed part is thin-walled, and processing difficulties are yielding after processing, and manufacturing cost is higher；Can only axially dismantle because of this traction sheave, group
Close, therefore dismounting is difficult.Notification number is " traction machine " of the U of CN 202625557, and the structure that it is recorded includes rotor, stator, turns
Axle, traction sheave, without sealed bearings, without sealed bearings enclosing cover, without sealed bearings inner cap, rear bearing, rear bearing cover, oil inlet passage,
Rotating shaft is installed on stator by without sealed bearings and rear bearing, and oil inlet passage is connected with the oil pocket without sealed bearings；Without seal shaft
Hold inner cap or without pressure relief opening is covered with outside sealed bearings, pressure relief opening is connected without sealed bearings oil pocket and oil catcher；Pressure relief opening outside
Pressure release screw is provided with, pressure release screw axial is hollow, the inner insertion pressure relief opening of pressure release screw, pressure release screw outer end connects with drain mast
Connect, drain mast is connected through rear bearing cover with oil catcher.The traction machine increases automatic discharging pressure by the oil pocket without sealed bearings
Power apparatus, solve the technology entered in stator, rotor or other parts without the liquid in sealed bearings oil pocket or gaseous state oil and ask
Topic.Found in actual motion, if draining screw breaks down or draining blockage is, it is necessary to ability after traction machine main shaft is pulled down
Maintenance, it is impossible to remote monitoring, very burden is brought to field maintenance work；Simultaneously because needing assembling draining screw, drain mast
Deng part, production cost is also accordingly increased.
