Definitions

  • the mass for balancing is added or removed at a position near the node of the rotation member in the predetermined resonance mode in which bending occurs at the rotation member. Due to this, when the rotation member vibrates in the predetermined resonance mode, the mass added or removed is not greatly displaced, and therefore it is possible to prevent or lessen the increase of the centrifugal force due to the mass. As a result, it is possible to prevent or lessen the increase in vibration due to the mass for balancing in the resonance mode in which bending occurs at the rotation member.
  • FIG. 3 is a graph showing the relationship between the rotation speed of the bobbin holder 9 and vibration.
  • a first resonance mode hereinafter, referred to as a "primary resonance mode”
  • a second resonance mode hereinafter, referred to as a “secondary resonance mode”
  • a third resonance mode hereinafter, referred to as a "tertiary resonance mode”
  • fourth and subsequent resonance modes will occur as the rotation speed further increases.
  • the bobbin holding portion 20 In the tertiary resonance mode, as shown in FIG. 4(c) , the bobbin holding portion 20 is bent and displaced. That is, the bobbin holding portion 20 behaves as a flexible rotor. Because of this, in the tertiary resonance mode, the weights added at the both-end positions P1 and P2 are displaced in a direction different from the cases in which the bobbin holding portion 20 behaves as a rigid rotor (see FIG. 4(a) and FIG. 4(b) , in the primary and secondary resonance modes). This disrupts the balance that has been achieved in the states of FIG. 4(a) and FIG. 4(b) , and further increases the vibration in the tertiary resonance mode, disadvantageously.
  • the vibration in the tertiary resonance mode is originally larger than that in the primary and secondary resonance modes. If such large vibration is further increased by the effect by the weights for balancing, the peak in the tertiary resonance mode shown in FIG. 3 is further heightened, which makes it difficult to increase the winding speed r.
  • step S4 unbalance correcting step in the present invention.
  • a weight 27 having an appropriate mass is attached into each of one or more threaded hole portions 26 out of the plurality of threaded hole portions 26 arranged in the circumferential direction.
  • the one or more threaded hole portions 26 are determined based on the measurement result of the amount of unbalance.
  • the balancing process is completed. It is preferable to check whether the amount of unbalance is less than the tolerance in the balancing machine after the balancing process is completed.
  • the correction speed p is lower than the rotation speed c at which the tertiary resonance mode occurs. Unbalance is reducible regardless of whether the correction speed is low or high, as long as an appropriate balancing method is used. However, when the correction speed is high, balancing using the balancing machine is difficult, and therefore in-place balancing is needed. In this case, the balancing process is laborious. Thus, setting the correction speed to a relatively low speed as described above makes the balancing process less laborious.
  • the bobbin holder 9 has the primary resonance mode (or the secondary resonance mode) in which bending occurs at the shaft supporting portion 22 when the bobbin holding portion 20 is rotated at the speed a (or b) which is lower than the rotation speed c of the tertiary resonance mode in which bending occurs at the bobbin holding portion 20; and the correction speed p is closer to the rotation speed a (or b) at which the primary resonance mode (or the secondary resonance mode) occurs than the rotation speed c at which the tertiary resonance mode occurs.
  • the bobbin holder 9 has the two resonance modes (the primary and secondary resonance modes) in which bending occurs at the shaft supporting portion 22 at the rotation speeds a and b, respectively, which are lower than the rotation speed c.
  • the correction speed p is between the rotation speed a at which the primary resonance mode occurs and the rotation speed b at which secondary resonance mode occurs.
  • the work of unbalance correction is performed at the speed p close to both the rotation speeds a and b of the primary and secondary resonance modes in each of which bending occurs at the shaft supporting portion 22. This makes it possible to reduce vibration well in the primary and secondary resonance modes.
  • the correction positions at which unbalance correction is made are the positions of the nodes N1 and N2.
  • the correction positions do not have to be exactly the same as the positions of the nodes N1 and N2. It is possible to reduce the vibration in the tertiary resonance mode as long as the correction positions are close to the nodes N1 and N2, respectively.
  • the length of the bobbin holding portion 20 in the axial direction is L.
  • the effect of reducing the vibration in the tertiary resonance mode is sufficiently provided when unbalance correction is made at a correction position within an axial distance range of L/10, the range being defined by taking each node N1, N2 as the midpoint of the range, as shown in FIG. 2 .
  • the two nodes N1 and N2 are generated at the bobbin holding portion 20 in the tertiary resonance mode, and unbalance correction is made at the positions of the positions of the two nodes N1 and N2 (in two planes).
  • a vibration test is performed to obtain the positions of the nodes N1 and N2 of the bobbin holding portion 20.
  • vibration analysis using a computer model may be performed instead of performing the vibration test.
