Abstract
The utility model discloses an external rotor assembly device of a direct current brushless motor. The external rotor assembly device comprises a steel ring, a spindle sleeve, a shaft and a magnetic tile. A connecting steel plate is disposed on one end of the steel ring. The magnetic tile is concentrically arranged on the inner wall of the steel ring. A plastic separation support is placed between the magnetic tile and the connecting steel plate. The plastic separation support is provided with a flange back-up ring. The wall surface of the flange back-up ring is tightly contacted with the wall surface of the internal diameter of the contact end of the magnetic tile. The adoption of the plastic separation support and the plastic flange back-up ring allows the magnetic tile to be fast and reliable and to be bonded inside the steel ring in a tidy and consistent manner, and also helps to ensure that the magnetic tile is prevented from magnetic leakage caused by the plastic separation support and the plastic flange back-up ring. The external rotor assembly device is suitable for various direct current brushless motors.
Description
Technical field
The utility model relates to a kind of dc brushless motor, especially a kind of dc brushless motor external rotor assembly apparatus.
Background technology
Existing dc brushless motor external rotor assembly apparatus is to be shaped on an irony step at iron ring between the iron plate with being connected, with this irony step as bonding magnetic shoe positioning step; Be bonded at magnetic shoe one by one on the iron ring inwall, overlap the dc brushless motor external rotor assembly apparatus of magnetic shoe marshalling thereby form one, yet; Because the irony step is a magnetic conductor; Can produce certain leakage field phenomenon, and influence dc brushless motor effective power, this is need be improved.
The utility model content
The technical problem that the utility model will solve provides a kind of can neatly being bonded in magnetic shoe one by one on the iron ring inwall, can prevent and reduce the dc brushless motor external rotor assembly apparatus of leakage field phenomenon again.
For solving the problems of the technologies described above, the utility model comprises iron ring, and iron ring one end is shaped on and connects iron plate; Axle sleeve; Axle and be contained in the magnetic shoe of iron ring inwall with one heart is equipped with the plastics shelf at magnetic shoe with being connected between the iron plate; The plastics shelf is being shaped on the flange back-up ring with magnetic shoe contact jaw internal diameter wall, and flange back-up ring wall becomes closely to contact with magnetic shoe contact jaw internal diameter wall.
Through putting the plastics shelf with being connected between the iron plate at magnetic shoe; With at the plastics shelf along magnetic shoe contact jaw system one circle flange back-up ring; On the one hand in process of production can each magnetic shoe is neat, coincide, firmly be bonded in the iron ring; Plastics shelf and plastics flange back-up ring can not produce the leakage field problem to magnetic shoe on the other hand, and the utility model is adapted at using in the various dc brushless motor external rotor assembly apparatus.
Description of drawings
Fig. 1 is a kind of dc brushless motor external rotor of the utility model assembly apparatus embodiment general structure generalized section;
Fig. 2 is the exploded perspective view of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described further:
Referring to Fig. 1 and Fig. 2, the utility model comprises iron ring 4, and iron ring 4 one ends are shaped on and connect iron plate 1; Connect iron plate 1 central authorities' system with axle sleeve 6; The fastening axle 7 that is equipped with of axle sleeve 6 central authorities, magnetic shoe 5 is mounted on iron ring 4 inwalls with one heart, is equipped with plastics shelf 2 at magnetic shoe 5 between the iron plate 1 with being connected; Plastics shelf 2 is being shaped on a flange back-up ring 3 with magnetic shoe 5 contact jaw internal diameter walls, and flange back-up ring 3 walls become closely to contact with magnetic shoe 5 contact jaw internal diameter walls.During production magnetic shoe 5 neat and consistent be mounted in the groove that the flange back-up ring 3 of plastics shelf 2 forms, thereby form one group produce quick, bonding reliable, the dc brushless motor external rotor assembly apparatus of few leakage field.
