Definitions

  • the air roll unit when the air roll unit is in operation, if the air supply to the air bearing is shut off due to a failure or an excessive impact is applied to the roll, the air bearing and the shaft come into contact with each other and the shaft is damaged. Sometimes. Depending on the degree of damage, the shaft must be replaced. In particular, when the roll and the shaft are integrally formed, when replacing the shaft, the roll must also be replaced at the same time, which increases the cost.
  • an air roll unit 1 includes a roll 2 having a shaft 21, a cylindrical collar 3 attached to the shaft 21, and an air bearing 4 that supports the collar 3 in a non-contact manner.
  • a thrust plate 5 that restricts the movement of the air bearing 4 in the thrust direction
  • a detent plate 6 that prevents the collar 3 from rotating relative to the shaft 21, and a housing 7 that holds the air bearing 4. .
  • the air bearing 4 is attached to the collar 3 so that the flange 43 and the flange 32 of the collar 3 face each other.
  • the collar 3 can be supported in the radial direction without contact (specifically, a compressed air layer L1 for a radial bearing described later between the outer peripheral surface 35 of the collar 3 and the inner peripheral surface 44 of the air bearing 4). 9)
  • the inner diameter r5 of the air bearing 4 is set to be larger than the outer diameter r3 of the collar 3 by twice the thickness of the radial air compression compressed air layer L1.
  • FIG. 8A is a front view of the housing 7, and FIG. 8B is a cross-sectional view taken along the line FF of FIG. 8A.
