Embodiment
In order to describe structure of the present invention and characteristics in detail, enumerate the relevant position of each member of several preferred embodiments and conjunction with figs. explanation the present invention below.
As shown in Figure 3, motor is equipped with a central siphon 34 on a shell block 1, central siphon 34 can be by shell block 1 one elongation moulding, also can make up and be fixed on the shell block 1, and central siphon 34 peripheries are nested with stator seat 2, and inside then is provided with bearing 32, and the central shaft 41 of rotor 4 can be worn and pull in the rotation of bearing 32 central authorities, and central shaft 41 1 ends are top 421, have the less annular groove of external diameter 42 near top 421 distolateral.
Utilize the characteristic of first and second clasp 45,46 unlike materials, first clasp 45 can be central shaft 41 a good supporting locating effect is provided, drop to avoid rotor 4 to get loose, 46 of second clasps can be central shaft 41 cushioning effect are provided, and produce noise to avoid the motor rotation.
As shown in Figure 4, be another embodiment of the present invention, it is three clasps of configuration between bearing 32 and top heart lid 17, are respectively first clasp 45, second clasp 46 and the 3rd clasp 47, and first, second and third clasp 45,46,47 is also buckled and held annular groove 42 places of being fixed in central shaft 41.
Wherein, first clasp 45 is a metal material, and second and third clasp 46,47 is a non-metallic material, and second and third clasp 46,47 lays respectively at the upper and lower position of first clasp 45, is the kenel of pressing from both sides first clasp 45 of pulling.
Second and third clasp 46,47 can adopt macromolecular material or its composite material, and the rigidity of first clasp 45 is bigger than second and third clasp 46,47, and the button hole internal diameter of first and third clasp 45,47 must be more than or equal to the button hole internal diameter of second clasp 46.
Thus, first clasp 45 can be central shaft 41 a good supporting locating effect is provided, and drops to avoid rotor 4 to get loose, and 46,47 of second and third clasps can provide cushioning effect between bearing 32 and central shaft 41, produces noise to avoid the motor rotation.
Adopt above-mentioned design, the present invention not only can thoroughly solve the Rotation Noise problem of motor, can prevent the rotor beat again and get loose, and promotes the stability of motor running, the real initiative that belongs in the middle of like product.
The above only is preferred embodiment of the present invention, uses the equivalent structure variation that specification of the present invention, claims or accompanying drawing are done such as, all should be included in the claim of the present invention.
