Abstract
The utility model discloses a support-type motor possessing an embedded bearing. The motor includes a first support, a second support, a stator assembly and a rotor assembly which are arranged between the first support and the second support, a wind wheel which is arranged on one side of the second support, the bearing which is shaped with the second support by injection molding, and a motor shaft which passes through the first support, the rotor assembly, the bearing, and the wind wheel. The support-type motor possessing the embedded bearing takes the bearing as an embedded member, and the bearing is shaped with the second support by injection molding, so the glue adding procedure is saved, the glue cost is reduced, the working reliability is improved, and the motor service lifetime is prolonged.
Description
Technical field
The utility model relates to a kind of stent-type motor with insert bearing.
Background technology
Then existing stent-type motor adds glue and fixes because its support and bearing fit are matched in clearance, and its operation is comparatively complicated, causes production and assembly cost higher, and the while also produces easily the problem of glue inefficacy and affects functional reliability.
Summary of the invention
The utility model purpose is: provide a kind of cost low and have a stent-type motor of insert bearing.
The technical solution of the utility model is: a kind of stent-type motor with insert bearing, it comprises: the first support, the second support, be arranged on stator module and rotor assembly between first and second support, be positioned at the second support one side fan blade, with the bearing of the second support injection mo(u)lding and the motor shaft that passes respectively the first support, rotor assembly, bearing, fan blade.
On the basis of technique scheme, further comprise following attached technical scheme:
Described the second support comprises base portion, is fixed and is used for the outlet housing of air-out with stator module, adjacent with fan blade and for the inlet section of air intake.
Its further comprise the center, inlet section and embed bearing central part, connect between inlet section and the central part several dowels and by each dowel between several fresh air inlets of forming of interval.
Described outlet housing extends axially and forms an enclosed cavity of both ends open from the base portion one.
The sectional area of described outlet housing is greater than the sectional area of inlet section, and less than the sectional area of base portion.
Described dowel is radial or arc shape or linearity.
The utility model advantage is:
Bearing is considered as inserts to the utility model and support carries out integrated injection molding, saves the cost that adds glue operation and glue, increases simultaneously functional reliability, thereby improve the life-span of motor.
Description of drawings
Below in conjunction with drawings and Examples the utility model is further described:
Fig. 1 is generalized section of the present utility model;
Fig. 2 is the schematic diagram of end cap in the utility model;
Wherein: 10, the first support; 20, the second support; 22, base portion; 24, outlet housing; 26, inlet section; 27, dowel; 28, central part; 29, fresh air inlet; 30, stator module; 40, rotor assembly; 50, fan blade; 60, bearing; 100, rotating shaft.
Embodiment
Embodiment: shown in Fig. 1-2, the utility model provides a kind of specific embodiment with stent-type motor of insert bearing, and it comprises: the first support 10, the second support 20, be arranged on stator module 30 and rotor assembly 40 between first and second support 10,20, be positioned at the second support 20 1 sides fan blade 50, with the bearing 60 of the second support 20 injection mo(u)ldings and the motor shaft 100 that passes respectively the first support 10, rotor assembly 40, bearing 60, fan blade 50.Wherein the first support 10 deserves to be called again support, and the second support 20 claims again lower carriage.
The second support 20 comprises base portion 22, be fixed with stator module 30 and be used for air-out outlet housing 24, adjacent with fan blade 50 and for the inlet section 26 of air intake, 24 centers, inlet section and embed bearing 60 central part 28, be connected between inlet section 24 and the central part 28 several dowels 27 and by each dowel 27 between several fresh air inlets 29 of forming of interval.Wherein outlet housing 24 extends axially and forms an enclosed cavity of both ends open from base portion 22 one, and the sectional area of outlet housing 24 is greater than the sectional area of inlet section 24, and less than the sectional area of base portion 22.Described dowel 27 is radial or arc shape or linearity.
Certainly above-described embodiment only is explanation technical conceive of the present invention and characteristics, and its purpose is to allow the people who is familiar with technique can understand content of the present invention and according to this enforcement, can not limit protection scope of the present invention with this.The all Spirit Essence of main technical schemes is done according to the present invention equivalent transformation or modification all should be encompassed within protection scope of the present invention.
