Abstract
The utility model relates to a smooth fan without noise. The smooth fan without noise which is composed of a stator assembly and an integral fan rotor assembly is proposed to provide a fan with the advantages of convenient manufacture and good performance. The stator assembly is composed of a stator seat, a stator and a stator winding, the stator base is provided with a cavity which can contain the stator and the integral inner fan rotor assembly, the stator is a ring which is formed by welding after folding two groups of half ring silicon steel sheet with the coil slot on the inner circumference and winding and embedding the stator winding, and the stator is arranged on the stator base. The integral fan rotor assembly is an integral which is composed of a spindle, a rotor and fan blades, one end of the spindle is arranged in the central through hole of the stator base, the other end is connected with the fan blades and the rotor through the central part of the fan blades to form an integral.
Description
The utility model belongs to ventilation equipment, particularly a kind of steady noiselessness fan.
Existing fan is made up of field frame assembly and assembly type fan propeller assembly usually, field frame assembly has stator seat, stator and stator winding, stator seat has the cavity that holds stator, the hollow shaft head that has the band central through hole in the central authorities of cavity, stator is formed by stacking by annular silicon steel sheet, have the coil groove week in it, stator winding and is installed on the stator seat with stator in the coil groove that is embedded in stator; Assembly type fan propeller assembly is made up of axle, rotor and fans, one end of axle has the axle spindle nose, rotor has the centre bore that allows axle to pass, and the one end has center reaming that the axle spindle nose is installed and the spindle nose (shown in annex 1) that fans is installed.Because stator is formed by stacking by annular silicon steel sheet, when the embedding stator winding, not only construction is inconvenient, speed is slow, and the broken string consume is high, and assembly type fan propeller assembly not only makes rotor, and the connectivity robustness between axle and the fans is poor, and very easily cause rotor, nonconcentricity between axle and the fans, thus shaking degree and noise increase when fans is rotated, and influence the useful life of fan.
The purpose of this utility model provides that a kind of stator winding is convenient around embedding, speed is fast, quality good, the steady noiselessness fan of fans stability of rotation noiselessness, fan long service life.
The utility model is made up of field frame assembly and integrated fan rotor assembly, field frame assembly is made up of stator seat, stator and stator winding, stator seat has the cavity that holds stator and integrated fan rotor assembly, has the hollow shaft head of band central through hole in the central authorities of cavity; Stator is for have the semi-ring silicon steel sheet annular superimposed and that be welded of coil groove in week behind the embedding stator winding in two groups, be installed on the stator seat, the integrated fan rotor assembly is the integral body that axle, rotor and fans constitute, one end of axle is loaded in the central through hole of stator seat, and its other end is linked to be integral body through the central part of fans and fans and rotor.
Because the utility model is made up of field frame assembly and integrated fan rotor assembly, field frame assembly is made up of stator seat, stator and stator winding, stator seat agree have the cavity that holds stator and integral type interior wing rotor assembly, has the hollow shaft head of band central through hole in the central authorities of cavity; Stator is the semi-ring silicon steel sheet annular superimposed and that be welded behind the embedding stator winding that has the coil groove in last two groups week, and be installed on the stator seat, the integrated fan rotor assembly is the integral body that axle, rotor and fans constitute, one end of axle is loaded in the central through hole of stator seat, and its other end is linked to be integral body through the central part of fans and fans and rotor.Make stator winding around embedding is convenient, speed is fast, quality is high, the integrated fan rotor assembly, not only avoided the nonconcentricity between axle, rotor and the fans, reduce when fans is rotated and rock and noise, improved the useful life of fan, thereby reached the purpose of this utility model.
Fig. 1 is the utility model decomposition texture schematic isometric.
Fig. 2 is the utility model structural representation profile.
Below in conjunction with accompanying drawing the utility model is further elaborated.
The utility model is made up of field frame assembly 1 and integrated fan rotor assembly 2, field frame assembly 1 is made up of stator seat 11, stator 12 and stator winding 13, stator seat 11 has the cavity 111 that holds stator 12 and integrated fan rotor assembly 2, has the hollow shaft head 113 of band central through hole 112 in the central authorities of cavity 111; Stator 12 is for have semi-ring silicon steel sheet 121 annulars superimposed and that be welded of coil groove 1211 in week behind the embedding stator winding in two groups, and be installed on the stator seat 11 through connecting bolt 122, the integral body of integrated fan rotor assembly 2 for constituting by axle 21, rotor 22 and fans 23, one end 211 of axle 21 is installed in the mesopore through hole 112 of stator seat 11, its other end has axle spindle nose 212, the outer surface 2121 of axle spindle nose 212 is smooth surface or the rough surface that has axial teeth groove or smooth, coarse alternate surface; Rotor 22 has the centre bore 221 that allows axle 21 to pass, has the center reaming 223 of holding axle spindle nose 212 at one end 222, end face at 222 ends has depression 224, surfaces externally and internally 225,226 at 222 ends is to have the rough surface of axial teeth groove or the rough surface of annular groove, and axle 21, rotor 22 and fans 23 constitute whole at the axle spindle nose 212 of axle 21 and 222 ends of rotor 22.
