Abstract
The invention discloses an YXKK-series high-voltage efficient tank type three-phase asynchronous motor which comprises a rotor and a stator. Inner fans are connected to two sides of the rotor and are provided with inner fan shaft sleeves, balance rings are connected onto the inner fan shaft sleeves, and balance grooves are formed in the left side and the right side of each balance ring; an outer fan is connected to the right end of the rotor and comprises an outer fan center plate and outer fan blades, center plate grooves are circumferentially formed in the outer fan center plate, the outer fan blades can be embedded in the center plate grooves, the shapes of the center plate grooves are matched with the shapes of the to-be-mounted outer fan blades, and blade barrier strips are vertically arranged at the left ends of the outer fan blades. The high-voltage efficient tank type three-phase asynchronous motor has the advantages that balance rings for the rotor of the motor are omitted, the balance grooves are additionally formed in the inner fan shaft sleeves, accordingly, the rotor can be lightened, the critical rotational speed can be increased, smooth ventilation and radiating effects can be realized, and the design cost can be reduced.
Description
Technical field
The present invention relates to technical field of motors, especially relate to a kind of yxkk series high voltage threephase asynchronous.
Background technology
Motor rotor in order to balance conveniently, as shown in figure 1, having equipped with two gimbal 2(gimbals 2 on rotor 1
Compensating groove 3, can fill balance weight), but, so not only increase rotor weight and reduce critical speed, impact ventilation and heat, also increase
Plus design cost；Motor external fan 7 carries axle sleeve 6, and axle sleeve 6 and rotor 1 adopt hot jacket, needs to heat axle sleeve 6, dismounting during installation
External fan is especially bothersome, trouble；Motor external fan flabellum 5 steel plate is welded on external fan former 4, in long-term high-speed cruising
In, weld seam easily ftractures, and flabellum comes off, or even causes motor to burn.
Content of the invention
It is an object of the invention to provide a kind of high-voltage box type threephase asynchronous, mitigate rotor weight and improve critical turn
Speed.
The technical scheme is that
High-voltage box type threephase asynchronous, including rotor and stator, the both sides of rotor are respectively connected with internal fan, internal fan
It is provided with internal fan axle sleeve, internal fan axle sleeve is connected with gimbal, the left and right sides of gimbal is equipped with compensating groove；The right side of rotor
End is connected with external fan, and external fan includes external fan former, external fan flabellum, and described external fan former circumferentially offers use
In the former fluting of setting-in external fan flabellum, the shape of former fluting is adapted with the shape of external fan flabellum to be installed, outward
The left end end of electric fan is vertically provided with flabellum blend stop, and the length that the length of flabellum blend stop is slotted with former is adapted, flabellum
Blend stop place plane is vertical with fan former place plane, using being welded to connect between flabellum blend stop and external fan former；Exogenous wind
The downside of fan former offers through hole, and the right-hand member end face correspondence of rotor offers fixing hole, and fixing hole is internal thread hole, fixing spiral shell
Bolt pass through external fan former on the downside of through hole and threaded with the fixing hole of rotor right-hand member.
The equal length that the length of flabellum blend stop is slotted with former.
Gimbal cancelled by the motor rotor of the present invention, increases compensating groove, so not only mitigate and turn on internal fan axle sleeve
Sub- weight improves critical speed, makes ventilation and heat smooth, can also reduce design cost；External fan cancelled by motor external fan
Set, external fan with being bolted directly on rotor, so dismounting external fan is especially saved trouble, conveniently；Motor external fan is fanned
Leaf steel plate is welded on external fan former, on former slot, flabellum is embedded in former groove and welds again, so solid can
By it is ensured that motor runs reliably and with long-term.
Brief description
Fig. 1 is the structural representation of existing electromotor；
Fig. 2 is the structural representation of the present invention.
Specific embodiment
As shown in Fig. 2 the present invention includes rotor 1 and stator, the both sides of rotor 1 are respectively connected with internal fan 8, and internal fan 8 sets
There is internal fan axle sleeve 9, internal fan axle sleeve 9 is connected with gimbal 10, the left and right sides of gimbal 10 is equipped with compensating groove 11.
The right-hand member of rotor 1 is connected with external fan 7, and external fan 7 includes external fan former 12, external fan flabellum 13, described outer
Former fluting 14 for being embedded in external fan flabellum 13, the width of former fluting 14 and length are circumferentially offered on fan former 12
Degree is adapted with the shape of external fan flabellum 13 to be installed, and the left end end of external fan flabellum 13 is provided with flabellum blend stop 15, fan
The length of the length of leaf blend stop 15 and former fluting 14 is suitable, and thickness sets as needed, flabellum blend stop 15 place plane and wind
Fan former 12 place plane is vertical.During installation, the left end of external fan flabellum 13 is placed in former fluting 14, makes the fan of left end simultaneously
Leaf blend stop 15 is stuck on the external fan former 12 at former fluting 14, then by flabellum blend stop 15, external fan former 12, external fan
Flabellum 13 welds, and forms stable connection.The downside of external fan former 12 offers through hole 16, and the right-hand member end face of rotor 1 corresponds to
Offer fixing hole 17, pass through the through hole 16 of external fan former 12 downside using fixing bolt 18 and be connected to rotor 1 right-hand member
In fixing hole 17, each external fan flabellum 13 all takes such connected mode.
