Description
Technical field
The present invention relates to technical field of motors, especially relate to a kind of YXKK series high voltage efficient three-phase asynchronous motor.
Background technology
Motor rotor, in order to balance conveniently, rotor 1 be equipped with on two gimbal 2(gimbals 2 and has compensating groove 3, can fill balance weight), but, so not only increase rotor weight and reduce critical whirling speed, affect ventilation and heat, also increase design cost; Motor external fan 7 tape spool 6 overlaps, and axle sleeve 6 and rotor 1 adopt hot jacket, needs to heat axle sleeve 6 during installation, and dismounting external fan is bothersome especially, trouble; Motor external fan flabellum 5 is with Plate Welding on external fan former 4, and in long-term high-speed cruising, weld seam easily ftractures, and flabellum comes off, and even causes motor to burn.
Summary of the invention
The object of the present invention is to provide the box threephase asynchronous of a kind of high efficient, high pressure, alleviate rotor weight and improve critical whirling speed.
Technical scheme of the present invention is:
The box threephase asynchronous of high efficient, high pressure, comprises rotor and stator, and the both sides of rotor are all connected with internal fan, and internal fan is provided with internal fan axle sleeve, and internal fan axle sleeve is connected with gimbal, and the left and right sides of gimbal is equipped with compensating groove; The right-hand member of rotor is connected with external fan, external fan comprises external fan former, external fan flabellum, the external fan former described external fan former circumferentially offered for setting-in external fan flabellum is slotted, the shape of the shape that external fan former is slotted and external fan flabellum to be installed is suitable, the left end end of external fan flabellum is vertically provided with flabellum blend stop, the length that the length of flabellum blend stop and external fan former are slotted is suitable, flabellum blend stop place plane and external fan former place plane orthogonal, adopt between flabellum blend stop and external fan former and be welded to connect; The downside of external 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, and set bolt passes the through hole on the downside of external fan former and is threaded with the fixing hole of rotor right-hand member.
The length of flabellum blend stop is equal with the length that external fan former is slotted.
Gimbal cancelled by motor rotor of the present invention, and internal fan axle sleeve increases compensating groove, so not only alleviates rotor weight and improves critical whirling speed, makes ventilation and heat smooth and easy, can also reduce design cost; External fan cover cancelled by motor external fan, and external fan bolt is directly fixed on rotor, dismantles external fan like this and saves trouble especially, facilitates; Motor external fan flabellum Plate Welding, on external fan former, external fan former is slotted, and flabellum is embedded in external fan former groove and welds, reliably solid like this, ensures that motor runs reliably and with long-term.
Accompanying drawing explanation
Fig. 1 is the structural representation of existing generator;
Fig. 2 is structural representation of the present invention.
Embodiment
As shown in Figure 2, the present invention includes rotor 1 and stator, the both sides of rotor 1 are all connected with internal fan 8, and internal fan 8 is provided with internal fan axle sleeve 9, internal fan axle sleeve 9 are connected with gimbal 10, and 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, external fan 7 comprises external fan former 12, external fan flabellum 13, described external fan former 12 circumferentially offers the external fan former fluting 14 for setting-in external fan flabellum 13, width and the shape of length and external fan flabellum 13 to be installed of external fan former fluting 14 are suitable, the left end end of external fan flabellum 13 is provided with flabellum blend stop 15, the length of flabellum blend stop 15 and external fan former slot 14 length suitable, thickness sets as required, flabellum blend stop 15 place plane and external fan former 12 place plane orthogonal.During installation, the left end of external fan flabellum 13 is placed in external fan former fluting 14, make the flabellum blend stop 15 of left end be stuck in external fan former slots on the external fan former 12 at 14 places simultaneously, then flabellum blend stop 15, external fan former 12, external fan flabellum 13 is welded, forms stable connection.The downside of external fan former 12 offers through hole 16, the right-hand member end face correspondence of rotor 1 offers fixing hole 17, use set bolt 18 through the through hole 16 on the downside of external fan former 12 and be connected in the fixing hole 17 of rotor 1 right-hand member, each external fan flabellum 13 all takes such connected mode.
