Specific implementation mode
In order to make those skilled in the art more fully understand technical scheme of the present invention, below in conjunction with the accompanying drawings and by specific
Embodiment is come the technical solution that further illustrates the present invention.
Embodiment one
As shown in Figure 1, a kind of roller washing machine using direct driving motor is present embodiments provided, when motor can be prevented long
Between operate caused by noise is big, vibration is big problem, while determinant problem not easy to remove can also be solved.Wherein, including it is interior
Cylinder, outer barrel 1 and motor, outer barrel rear wall are equipped with the axle sleeve 2 passed through for inner cylinder drive shaft, and motor stator 3 is set in the outer of axle sleeve 2
It is fixedly mounted on outer barrel rear wall in week, which is characterized in that the inner edge of the motor stator 3 and the non-contact setting in 2 periphery of axle sleeve.
Wherein, positioning snap ring 4, the positioning are provided between 2 periphery of the inner edge of motor stator 3 and axle sleeve in the present embodiment
Snap ring 4 is arranged in the gap formed between axle sleeve 2 and stator 3.Meanwhile axially setting is fluted along it for the positioning snap ring 4
5, as Figure 2-3, and the groove 5 is circumferentially distributed on the side wall of the positioning snap ring 4.Motor positions card in non-operating
Ring 4 is unlikely to deform, and can be accurately positioned motor stator；After motor operates, axle sleeve 2 and positioning snap ring 4 are heated, wherein positioning card
The heated rear elasticity of ring 4 increases, and absorbs the deformation that axle sleeve 2 generates by groove 5, after realizing reduction 2 temperature distortion of axle sleeve
Influence to the stator 3 and 8 gap of rotor of motor, and then the noise generated and vibration are reduced, and keep stator hotter in axle sleeve
When it is easily disassembled.
The material of positioning snap ring 4 described above is plastics, i.e. HD-PE materials.The groove 5 is trapezium structure simultaneously.It will
Groove is set as trapezium structure, deformation effect that axle sleeve generates is absorbed for other structures more preferably, while trapezium structure
4 structure of positioning snap ring can be enable minimal to use material, also make positioning snap ring 4 lighter with annular spread.
Positioning snap ring 4 provided in this embodiment can absorb the deformation of axle sleeve 2 after axle sleeve 2 is heated, not interfere with electricity
Gap between machine stator 3 and rotor 8 effectively prevents the increase of noise and vibration, simultaneously because between stator 3 and rotor 8
Gap variation it is small or unchanged, stator 3 can be made more easy in disassembly process, without wait for axle sleeve 2 cooling after
It dismantles again, further saves the maintenance time of motor.
Embodiment two
As shown in figure 4, a kind of roller washing machine using direct driving motor is present embodiments provided, when motor can be prevented long
Between operate caused by noise is big, vibration is big problem, while determinant problem not easy to remove can also be solved.Wherein, including it is interior
Cylinder, outer barrel 1 and motor, outer barrel rear wall are equipped with the axle sleeve 2 passed through for inner cylinder drive shaft, and motor stator 3 is set in the outer of axle sleeve 2
It is fixedly mounted on outer barrel rear wall in week, which is characterized in that the inner edge of the motor stator 3 and the non-contact setting in 2 periphery of axle sleeve.
As shown in Figure 5,6, the inner edge of the motor stator 3 and the non-contact setting in 2 periphery of axle sleeve, and the inner edge of the motor stator 3 with
It is provided with gap between 2 periphery of axle sleeve, the first installation positioning surface 6, the first installation positioning surface 6 are provided on the stator 3
With 1 joint of the outer barrel, the second installation positioning surface 7 and the second peace with 3 joint of the stator are provided on the outer barrel 1
Set plane 7.
Wherein, it is circular orientation face that the first installation positioning surface 6 described above installs positioning surface 7 with described second, and institute
It is taper surface to state the first installation positioning surface 6 and install positioning surface 7 with described second.And it is described first installation positioning surface 6 with it is described
Angle between the cross section and horizontal plane of second installation positioning surface 7 is 10 °.
Although the outer diameter that axle sleeve 2 stretches into one end in the stator 3 of motor is less than 3 internal diameter of stator, determinant can be solved and turned
Noise caused by gap changes between son vibrates greatly, but this kind of set-up mode also results in the positioning between stator and outer barrel
Inaccurately；And the angle installed the first installation positioning surface 6 and second between the cross section and horizontal plane of positioning surface 7 is set as
10 °, the first installation positioning surface 6 and second can be made to install and contact and be more bonded between positioning surface 7, make gap between the two into
One step reduces, and then can realize being accurately positioned between motor stator and outer barrel 2, and can solve that determinant is not easy to remove to ask
Topic.
