Description
Technical field
The utility model relates to a kind of elevator hoist, is specially adapted to the permanent magnetic synchronous traction machine of outer-rotor structure.
Background technology
Permanent-magnetic synchronous tractor for elevator, turn very low, generally below 300rpm, so, unlike y series motor, there is fan to force cooling, but employing self-radiating, permanent magnetic synchronous traction machine for existing outer-rotor structure, in order to guarantee that foreign matter can not enter motor internal, generally all require motor to adopt IP41 protection, so stator seals at motor internal, the heat that stator winding produces is all the mode by conduction: winding → iron core → support → extraneous air natural circulation, obviously, this radiating mode weak effect.
Chinese patent: a kind of Novel traction machine support all becomes cantilever-shaped, the patent No.: CN201220737382, described on support inner chamber perisporium and be provided with several radiating fins and reinforced rib, and bottom is provided with several ventilating heat dissipating holes, described ventilating heat dissipating hole is connected to form by large stepped hole and small stair hole, and the problem that this scheme exists is: ventilating heat dissipating hole is connected to form by large stepped hole and small stair hole, in technique, be difficult to realize, and hole can not be done greatly, so radiating effect is poor.
Chinese patent: a kind of towing machine that is easy to heat radiation, the patent No.: CN201320333242 has announced a kind of towing machine, on towing machine casing, offers vent window, in this vent window, radiator fan is housed; The problem that this scheme exists is: radiator fan just, facing to winding blowing or exhausting, does not form circulation wind path, so radiating effect is unsatisfactory.
Summary of the invention
The utility model object can overcome prior art deficiency exactly, a kind of feasible process is provided, has ventilation circuit, good heat dissipation, the permanent magnetic synchronous traction machine with aeration structure easy to maintenance.
The utility model object is achieved in that and comprises support, be arranged on the circular stator on support, the ring-type outer rotor being fixed together with traction sheave with traction wheel shaft, support comprises the pedestal of bottom, be arranged on the stator base that cross section on pedestal is " huge " shape, on the axis of the horizontal cylinder at stator base middle part, be provided with the perforation of traction wheel shaft, circular stator sleeve is connected on horizontal cylinder, ring-type outer rotor is socketed in circular stator outside, traction wheel shaft passes through bearing cross-under in the perforation of traction wheel shaft, the stator winding end of circular stator is adjacent with the annular side of stator base and form certain a. g., its special feature is: directly over stator base annular side, under be respectively arranged with two breather ports.
Principle of work is: cold air from breather port under support enter → contact with stator winding end → after the flow → cold air of circular clearance of stator winding end and support inner end surface contact with winding, naturally raise → cold air of temperature becomes hot air formation up current → from breather port discharge directly over support, formation cooling circuit.
In order further to increase radiating effect, at least one in two breather ports is provided with cooling fan, forces cooling.While adopting two breather ports all cooling fan to be set, directly over breather port be the cooling fan blowing outward, under breather port be the cooling fan blowing inward.
Here, laterally in the annular side in cylinder outside, be provided with annular installation base, the screw threads that is horizontally through circular stator is connected on annular installation base circular stator is fixed on annular installation base, like this, both guaranteed that the stator winding end of circular stator and the annular side of stator base formed certain a. g., meanwhile, also facilitated and manufactured installation, dismounting.
beneficial effect

Sequence number explanation in figure: ring-type outer rotor 1, circular stator 2, stator winding 2a, support 3, pedestal 3a, stator base 3b, laterally cylinder 3c, the perforation of traction wheel shaft 3d, annular side 3e, a. g. 3f, directly over breather port 4, under breather port 6, cooling fan 7, traction wheel shaft 8, traction sheave 9, bearing 10, annular installation base 11, screw 12.
The specific embodiment
Below in conjunction with drawings and Examples, the utility model is further described:
The utility model comprises support 3, be arranged on the circular stator 2 on support 3, the ring-type outer rotor 1 being fixed together with traction sheave 9 with traction wheel shaft 8, support 3 comprises the pedestal 3a of bottom, be arranged on the stator base 3b that cross section on pedestal 3a is " huge " shape, on the axis of the horizontal cylinder 3c at stator base 3b middle part, be provided with traction wheel shaft perforation 3d, circular stator 2 is socketed on horizontal cylinder 3c, ring-type outer rotor 1 is socketed in circular stator 2 outsides, traction wheel shaft 8 is bored a hole on 3d at traction wheel shaft by bearing 10 cross-under, the stator winding 2a end of circular stator 2 is adjacent with the annular side 3e of stator base 3b and form certain a. g. 3f, its special feature is: directly over stator base 3b annular side 3e, under be respectively arranged with directly over breather port 4, under breather port 6.
Principle of work is: cold air from breather port 6 under support 3 enter → mobile with the annular a. g. 3f of support 3 inner end surfaces through stator winding 2a end with contact → air of stator winding 2a end, as shown in Fig. 2 arrow, after arrow is depicted as air flow → cold air and contacts with stator winding 2a, naturally raises → cold air of temperature becomes hot air and forms up current → from breather port 4 discharges directly over support 3, formation cooling circuit.
If towing machine heating is excessive, and the heat radiation of two breather ports has not met the demands, can increase by a cooling fan 7 in breather port 6 positions under support 3 again, cooling fan 7 is blown into cold wind, forced draft enters, and discharges fast from breather port directly over support 34, increases radiating effect.
While adopting two breather ports all cooling fan to be set, directly over support 3, breather port 4 is the cooling fans that blow outward, and under support 3, breather port 6 is the cooling fans that blow inward.
Laterally on the annular side 3e in cylinder 3c outside, be provided with annular installation base 11, the screw 12 that is horizontally through circular stator 2 is screwed in annular installation base 11 circular stator 2 is fixed on annular installation base 11, like this, both guaranteed that stator winding 5 ends of circular stator 2 and the annular side 3e of stator base 3b formed certain a. g. 3f, meanwhile, also facilitated and manufactured installation, dismounting.
