Description
Technical field
The utility model relates to a kind of rotor, especially a kind of motor that is used for the rotor of air-conditioning fan and uses this rotor.
Background technology
For adjusting indoor temperature, air conditioner all is equipped with the fan to indoor air-supply, send to indoor with the cold or hot-air that air conditioner is produced, a kind of fan structure of existing air conditioner as shown in Figure 1, comprise motor 1, fan blade 2 and bracing frame 3, wherein motor 1 has motor stator 11 and rotor 13, and a columned rotor 12 of holding rotor 13 is arranged in the motor stator 11.One end of fan blade 2 is fixed on the axle of motor 1, and the other end cooperates by axis hole and is connected with bracing frame 3, and is fixed between motor 1 and the bracing frame 3, and motor 1 is fixed in the air-conditioning internal machine with 3 of bracing frames, and fan blade 2 drives rotation by motor 1.
Referring to Fig. 2, motor 1 is made up of motor stator 11, rotor 13, clutch shaft bearing 15, second bearing 16 and end cap 17.One end of the output shaft 14 of rotor 13 is fixed on the motor stator 11 by clutch shaft bearing 15, and the other end passes second bearing 16 and is fixed on the end cap 17.After motor 1 energising, rotation under rotor 13 can drive in the rotating magnetic field that motor stator 11 produces, thus drive output shaft 14 rotations.
It is elongated cylindric that fan blade 2 is, and its end near motor 1 is provided with the axis hole 21 that cooperates with output shaft 14.As seen from Figure 1, after motor 1 assembling finished, an end of output shaft 14 was anchored in the axis hole 21.Certainly, output shaft 14 also can cooperate to wait with axis hole 21 by keyway realizes torque drive, drives the rotation of fan blade 2.
But, because fan blade 2 cooperates meeting because of designing the former of own or processing technology thereby having the gap with 14 of output shafts, understand off-axis in the process that causes fan blade 2 to be rotated, and cause vibration and the formation noise, and, therefore need in air conditioner, reserve certain space because fan blade 2 vibrations can take than large space.Simultaneously, because motor 1 is connected with fan blade 2 by output shaft 14, motor when the fan blade 2 of driving elongate, the problem that can exist output shaft 14 to bend because of transfer torque, under particularly elongated output shaft 14 and the long fan blade situation, these problems are particularly outstanding.
In addition, the said fans assembly process is more loaded down with trivial details.During the assembling fan, clutch shaft bearing need be enclosed within on the output shaft 14, then rotor 13 be put into the rotor 12 of motor stator 11, second bearing 16 is sleeved on the output shaft 14 again, cover end cap 17, last motor 1 is contained in an end of fan blade 2.Because installation step is various, output shaft 14 requires height with the assembly precision of fan blade 2, has limited the raising of fan efficiency of assembling.
Summary of the invention
Main purpose of the present utility model provides a kind of vibration that fan blade when rotation produce and rotor of noise of reducing;
Another purpose of the present utility model provides a kind of rotor of avoiding the bending shaft of rotor;
A purpose more of the present utility model provides the simple motor of a kind of assembly process.
For realizing above-mentioned main purpose, the rotor that the utility model provides comprises rotor body and armature spindle, wherein, armature spindle reaches the end axle that stretches out from the fan blade both ends of the surface by fan blade and constitutes, rotor body is fixed on the end face of fan blade, and rotor body has the stator installation hole that is used to hold motor stator.
By such scheme as seen, the axle that fan blade and both ends of the surface thereof are stretched out is formed armature spindle, and promptly the output shaft of fan blade and rotor forms one, does not need to be connected by axis hole cooperation realization between the output shaft of fan blade and rotor.Therefore, the vibration that takes place in the time of can effectively avoiding the fan blade rotation, and reduce the noise that produces when rotating.And, do not need between the armature spindle of rotor and the fan blade to cooperate and realize being connected by axis hole, effectively alleviated the phenomenon that armature spindle bends when rotated.
A preferred scheme is, rotor body has the magnet of cup-shaped, and magnet surrounds the stator installation hole, and armature spindle is arranged on the axis of magnet.And magnet comprises circular sidewall and the diapire that is fixed on fan blade one end, and diapire is provided with at least one and is used for the through hole that is connected with fan blade, and the part of fan blade end face is embedded in the through hole.
Like this, the magnet of rotor body is fixedlyed connected with fan blade by through hole, and magnet is connected more firm with fan blade, the rotation of drive fan blade better during the rotor body rotation.
For realizing an above-mentioned purpose again, the motor that the utility model provides comprises motor stator and rotor, wherein rotor comprises rotor body and armature spindle, armature spindle reaches the end axle that stretches out from the fan blade both ends of the surface by fan blade and constitutes, rotor body is fixed on the end face of fan blade, and rotor body has a stator installation hole, and at least a portion of motor stator is positioned at the stator installation hole, and the free end of armature spindle is supported on the bracing frame by a bearing.
This shows that rotor body is fixed on an end of fan blade, the output shaft of rotor and fan blade form one, the vibration that produces when avoiding the fan blade rotation, and the generation of minimizing noise.Simultaneously, because fan blade and rotor body form one, during the assembling fan electromotor, only motor stator need be sleeved in the stator installation hole of rotor body, assembly process is simple, can effectively improve the efficiency of assembling of motor.
