Definitions

  • the rotation speed of the spindle shaft directly affects the number of twists applied to the yarn, the rotation speed of the drive motor must be accurately maintained at a desired value during twisting in order to obtain high-quality twisted yarns.
  • a large number of drive motors must be individually inspected for quality in order to prevent the quality of twisted yarns from varying for each spindle.
  • the motor is actually rotationally driven to measure the intensity of magnetic fields, a voltage value, and a current value.
  • a power line for supplying power to the motor is wired in a support table and the spindle shaft, and if this wiring is located below a lubricant supply port, a lubricant may spill and attach to the wiring during a lubricant supply, adversely affecting the wiring.
  • the spindle shaft 1 extends downward from the rotating disc 6, and the drive motor M for rotationally driving the spindle shaft 1 is coaxially provided on the extension of the shaft. That is, while the spindle shaft 1 is installed, the drive motor M is directly provided on part of the spindle shaft 1, and no couplings for transmitting a rotation torque are used between the two coaxial shafts arranged in the axial direction.
  • the rotating section of the drive motor M is installed so that the lower bearing 17 is located between the lower bearing support member 15 and the small diameter section 11b of the sleeve 11 at its lower end, while the upper bearing 18 is located between the upper bearing support member 16 and the small diameter section 11b of the sleeve 11 at its upper end.
  • the upper and lower caps 19, 20 are installed to constitute the drive motor M in which the stator 14 is located outside the rotor 12 opposite thereto to provide a predetermined rotation torque to the rotor 12.
  • the drive motor M is actually rotationally driven to carry out predetermined quality inspections.
  • the inserted spindle shaft 1 is guided through the tapered hole 11c so as to be accurately positioned on a predetermined center axis (the rotating axis of the drive motor M) and at a predetermined height. This enables the spindle shaft 1 to be rotated stably at a high speed.
  • an air hole 104b in communication with the guide section 115a is formed at the lower end of the spindle shaft 104, and air can be supplied from the lower end of the air hole 104b.
  • the air flows from the center of the guide section 115a toward its outer circumference, so the raw yarn 112a entering the tension hole 147a in the tension device 147 is automatically guided to the outer circumferential end of the guide section 115a of the rotating disc 115.
  • a detection magnet 133 is secured to the spindle shaft 104 under the rotor magnet 132 in order to detect the rotation speed of the spindle shaft 104, and is composed of a plastic magnet that is a permanent magnet having a low magnetic force (weaker than that of the rotor magnet 132).
  • a magnetic sensor 133a is mounted on the motor support section 126 opposite to the detection magnet 133 to detect magnetic fields from the magnet sensor 133 in order to detect the rotation speed of the spindle shaft 104.
  • a lubricant is supplied from the upper lubricant supply port 127c through the lubricant passage 127d to the bearing 127a.
  • the passage outlet 127e is located above the bearing 127a, a lubricant filled in a space 136 inside the upper support member 127 through the passage outlet 127e is reliably supplied to the lower bearing 127a.
  • the wiring port 126e When the wiring port 126e is formed approximately vertically under the lubricant supply port 126c or 127c and if a lubricant spills while being supplied to the lubricant supply port 126c, 127c, the spilled lubricant will inconveniently adhere to the wiring.
  • the wiring port 126e must be at least formed at a position other than one approximately vertically under the lubricant supply port and its neighborhood.
  • the drive motor 160 is configured as a DC brushless motor comprising the rotor magnet 182 secured to the spindle shaft 154 and comprising a permanent magnet having a high magnetic force, the stator coil 181 placed in the outer circumferential section of the rotor magnet 182 and including the iron core 181a, and the motor housing 184 covering the stator coil 181 and the rotor magnet 182.
  • the drive motor 160 is capable of fast rotational driving.
  • a lubricant is supplied from the upper lubricant supply port 177c through the lubricant passage 177d to the bearing 177a from above.
  • a bolt 143 is inserted and screwed in the screw hole 179a in the cap 179 from below.
  • the bolt 143 inserted and screwed in the screw hole 179a abuts on the lower end of the spindle shaft 154.
  • the bolt 143 is further screwed to push the spindle shaft 154 upward, thereby enabling the shaft 154 to be simply removed.
