Description
Technical field
The invention belongs to elevator technology field, particularly a kind of magnetic suspension external rotor elevator traction machine.
Background technology
Bearing for elevator traction machine will bear the weight of lift car, counterweight and passenger, current bearing is all mechanical bearing, so large pressure causes the frictional force of Bearing inner very large, and motor needs to overcome this part frictional force that traction sheave could be driven to rotate, the energy consumption of whole system is caused to increase, such as application number is 200920278926.1, and denomination of invention is the Chinese patent of external rotor motor direct traction type oil extractor.
Summary of the invention
The present invention is directed to current elevator traction machine internal bearings frictional force very large, the technical problem that abrasion increases, and a kind of magnetic suspension external rotor elevator traction machine is provided.
For solving the problems of the technologies described above, the technical solution used in the present invention is:
A kind of magnetic suspension external rotor elevator traction machine, comprise main shaft, stator module, stator coil and traction sheave, traction sheave is installed on main shaft by bearing, both sides main shaft being positioned at bearing are provided with annular magnetic steel, and the magnetic pole of annular magnetic steel inner ring is N pole, is provided with coil between annular magnetic steel and main shaft, coil is fixed on main shaft, magnet steel is fixed on traction sheave, and the outer ring magnetic pole being positioned at the coil of main shaft the first half is N pole, and the outer ring magnetic pole being positioned at the coil of main shaft the latter half is S pole.
Described stator module is connected with integrated spindle axis.
Described traction sheave is around main axis under the driving of stator coil, and traction sheave is external rotor.
After the present invention adopts said structure, there is following technique effect:
A kind of magnetic suspension external rotor elevator traction machine of the present invention can increase substantially the useful life of bearing, and can be used for more than 20m/s express elevator, reduces bearing maintenance cost simultaneously, improves the quality of products.
Accompanying drawing explanation
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 shows overall structure of the present invention;
Fig. 2 shows the partial enlarged view in Fig. 1;
Fig. 3 shows the structure of magnet steel of the present invention and coil.
Embodiment
For making object of the present invention and technical scheme clearly, below in conjunction with the embodiment of the present invention, technical scheme of the present invention is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present invention, instead of whole embodiments.Based on described embodiments of the invention, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, all belongs to the scope of protection of the invention.
As Figure 1-3, a kind of magnetic suspension external rotor elevator traction machine, comprises main shaft 1, stator module 2, traction sheave 3, annular magnetic steel 4, coil 5, stator coil 6 and bearing 7.
A kind of magnetic suspension external rotor elevator traction machine, comprise main shaft, stator module, stator coil and traction sheave, traction sheave is installed on main shaft by bearing, both sides main shaft being positioned at bearing are provided with annular magnetic steel, and the magnetic pole of annular magnetic steel inner ring is N pole, is provided with coil between annular magnetic steel and main shaft, coil is fixed on main shaft, magnet steel is fixed on traction sheave, and the outer ring magnetic pole being positioned at the coil of main shaft the first half is N pole, and the outer ring magnetic pole being positioned at the coil of main shaft the latter half is S pole.
In the present invention, when name up and down in described main shaft the first half, main shaft the latter half is static with elevator traction machine, the direction that bearing bears dead load is downward, again because main shaft is cylindrical structure, for regular shape, divide with its center line place horizontal plane, being divided into upper and lower two halves is easy understand, therefore in order to distinguish the magnetic pole of coil, name as difference using this.
Described traction sheave is around main axis under the driving of stator coil, and traction sheave is external rotor.
The load of existing traction machine car counterweight all acts on rotor assembly, and on traction sheave, then pass to bearing by rotor assembly, thus bearing is subject to very large radial load.
When described magnetic suspension external rotor elevator traction machine is static, bearings rotor assembly, bearing is by dead load; When described magnetic suspension external rotor elevator traction machine runs, after upper semi-circle coil electricity, its outer ring magnetic pole is N pole, produces repulsion with the N pole of magnet steel inner ring; After lower half circle coil electricity, its outer ring magnetic pole is S pole, produces suction with the N pole of magnet steel inner ring, and these two masterpieces are used on rotor assembly, make the power that rotor assembly is subject to upwards, contrary with the load of car counterweight, thus make bearing not by radial load, namely bearing rotates under no-load condition.
Preferably, described stator module is connected with integrated spindle axis, and stator coil winding is in the outside of stator module.
Those skilled in the art of the present technique are appreciated that unless otherwise defined, and all terms used herein (comprising technical term and scientific terminology) have the meaning identical with the general understanding of the those of ordinary skill in field belonging to the present invention.Should also be understood that those terms defined in such as general dictionary should be understood to have the meaning consistent with the meaning in the context of prior art, unless and define as here, can not explain by idealized or too formal implication.
The implication of the "and/or" described in the present invention refers to respective individualism or both simultaneous situations include interior.
The implication of " inside and outside " described in the present invention refers to relative to equipment itself, in the direction of sensing equipment inside is, otherwise is outward.
When the implication of " left and right " described in the present invention refers to reader just to accompanying drawing, the left side of reader is a left side, and the right of reader is the right side.
The indirect connection that can be the direct connection between parts also can be by other parts between parts of the implication of " connection " described in the present invention.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on specification, must determine its technical scope according to right.
