  • DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS
  • [0018]
    Preferred embodiments in accordance with the present invention will now be described with reference to the accompanying drawings.
  • [0019]
    Referring to FIGS. 1 and 2, a first embodiment in accordance with the present invention generally comprises a base 1, a metal axle tube 2, and a rotor 3.
  • [0020]
    The base 1 may be a conventional casing for motors or heat-dissipating fans. In this preferred embodiment, the base 1 may further comprises a fixed balancing sheet 11 made of a magnetically conductive material for mutual attraction with a permanent magnet 33 of the rotor 3.
  • [0021]
    The metal axle tube 2 is made of a magnetically conductive material and has an end fixed to the base 1. A conventional stator bobbin 12 is mounted to the other end of the metal axle tube 2. In addition, the other end of the metal axle tube 2 may have a flange 20 formed thereon for preventing disengagement of the stator bobbin 12. Mounted in the metal axle tube 2 are a first holding member 21, a second holding member 22, a supporting member 23, and a fixing member 24 that can be secured to an inner periphery of the metal axle tube 2 by any fixing means. The first holding member 21 is tightly engaged with the inner periphery of the metal axle tube 2 by force-fitting. The second holding member 23 and the supporting member 23 may also be tightly engaged with the inner periphery of the metal axle tube 2 by force-fitting, and the second holding member 22 and the supporting member 23 sandwiches the fixing member 24, which is a simple method for mounting these members.
  • [0022]
    Each of the first holding member 21 and the second holding member 22 has a hole 211, 221 through which a shaft 31 of the rotor 3 extends. Preferably, the shaft 31 has a minimum contact area with the first holding member 21 and the second holding member 22. As illustrated in FIG. 2, an inner flange 212 is formed on an inner periphery defining the hole 211 of the first holding member 21 and an inner flange 222 is formed on an inner periphery defining the hole 221 of the second holding member 22.
  • [0023]
    The supporting member 23 comprises a supporting portion 230 that may be a closed bottom side of the supporting member 23. Alternatively, as illustrated in FIGS. 1 and 2, the supporting member 23 has a hole 231 and a supporting plate 232 for covering the hole 231. A distal end of the shaft 31 of the rotor 3 rests on the supporting portion 230 or the supporting plate 232. The fixing member 24 may be a conventional retaining ring and is fixed in the metal axle tube 2 at an appropriate location. In addition, the fixing member 24 comprises a hole 241, a periphery defining the hole 241 being deformable to allow easy passage of the shaft 31 of the rotor 3.
  • [0024]
    The shaft 31 is mounted to a central portion of the rotor 3. The shaft 31 extends through the hole 211 of the first holding member 2, the hole 221 of the second holding member 22, and the hole 241 of the fixing member 24 with the distal end of the shaft 31 resting on the supporting portion 230 or the supporting plate 23 of the supporting member 23. In addition, the shaft 31 has a retaining groove 32 for securely receiving the periphery defining the hole 241 of the fixing member 24 to thereby prevent disengagement of the rotor 3. The shaft 31 and the inner flanges 212 and 222 of the first and second holding members 21 and 22 have a minimum gap or a slight contact therebetween, best shown in FIG. 3. A permanent magnet 33 is mounted to the rotor 3 for induction with the stator bobbin 12 and for attraction with the balancing sheet 11.
  • [0025]
    [0025]FIG. 4 illustrates a second embodiment of the present invention, wherein the first holding member and the second holding member are integrally formed to form a single holding member 25 having a hole 251 through which the shaft 31 extends. Two inner flanges 252 are formed on an inner periphery defining the hole 251 and the shaft 31 have a minimum gap or a slight contact therebetween. In addition, the inner flanges 252 have an appropriate space therebetween. Preferably, the inner flanges 252 are respectively formed on two ends of the inner periphery defining the hole 251. Thus, the holding member 25 may have the smallest contact area with the shaft 31. In addition, a central axis of the shaft 31 has the smallest deviation from a central axis of the axle tube 20 when the shaft 31 is not turned. And rotation of the shaft 31 becomes stable immediately after it is turned.
  • [0026]
    [0026]FIG. 5 illustrates a third embodiment of the present invention, wherein the only one holding member 22 is mounted in the metal axle tube 2. The holding member 22 has a hole 221 through which the shaft 31 extends. An inner flange 222 is formed on an inner periphery defining the hole 221. The inner flange 222 and the shaft 31 have a minimum gap or a slight contact therebetween. An end of the shaft 31 is mounted to a central bulge 34 of the rotor 3. The central bulge 34 of the rotor 3 has a diameter slightly smaller than an inner diameter of the metal axle tube 2 such that the central bulge 34 and the inner periphery of the metal axle tube 2 have a minimum gap or a slight contact therebetween. Thus, the central bulge 34 of the rotor 3 also provides a holding function and cooperates with the holding member 22 to rotatably hold the shaft 31 such that the central axis of the shaft 31 has the smallest deviation from the central axis of the axle tube 20 when the shaft 31 is not turned.
  • [0027]
    [0027]FIG. 6 illustrates a fourth embodiment of the present invention, wherein only one holding member 22 is mounted in the metal axle tube 2. The holding member 22 has a hole 221 through which the shaft 31 extends. An inner flange 222 is formed on an inner periphery defining the hole 221. The inner flange 222 and the shaft 31 have a minimum gap or a slight contact therebetween. An auxiliary holding member 35 made of rubber or plastic material is mounted around the shaft 31. As illustrated in FIG. 6, the shaft 31 may include an annular groove for securely receiving the auxiliary holding member 35. The auxiliary holding member 35 has a diameter slightly smaller than an inner diameter of the metal axle tube 2 such that the auxiliary holding member 35 and the inner periphery of the metal axle tube 2 have a minimum gap or a slight contact therebetween. Thus, the auxiliary holding member 35 also provides a holding function and cooperates with the holding member 22 to rotatably hold the shaft 31 such that the central axis of the shaft 31 has the smallest deviation from the central axis of the axle tube 20 when the shaft 31 is not turned.
  • [0028]
    [0028]FIG. 7 illustrates a fifth embodiment of the invention, wherein two auxiliary holding members 35 a and 35 b made of rubber or plastic material are mounted around the shaft 31. The auxiliary holding members 35 a and 35 b are securely mounted around the shaft 31. Each auxiliary holding member 35 a, 35 b has a diameter slightly smaller than an inner diameter of the metal axle tube 2 such that the auxiliary holding members 35 a and 35 b and the inner periphery of the metal axle tube 2 have a minimum gap or a slight contact therebetween. Thus, the auxiliary holding members 35 together provide a holding function for rotatably holding the shaft 31 such that the central axis of the shaft 31 has the smallest deviation from the central axis of the axle tube 20 when the shaft 31 is not turned.
  • [0029]
    By means of provision of the supporting structure for a rotor in accordance with the present invention, the shaft 31 of the rotor 3 is merely supported by the supporting portion 230 or the supporting plate 232 of the supporting member 23 at the distal end thereof. In addition, the shaft 31 and the inner periphery of the metal axle tube 2 have a minimum gap or a slight contact therebetween by means of provision of the auxiliary holding member(s) 35 or the central bulge 34. Alternatively, the two holding members 21 and 22 and the shaft 31 have a minimum gap or a slight contact therebetween such that the central axis of the shaft 31 has the smallest deviation from the central axis of the axle tube 20 when the shaft 31 is not turned. And rotation of the shaft 31 becomes stable immediately after it is turned. Accordingly, the rotational friction and rotational noise of the shaft 31 can be reduced to the least condition. Furthermore, the rotor 3 can be processed and manufactured easily and the assembling procedure of the rotor 3 is simple, thereby reducing the manufacture cost.
  • [0030]
