Title:
ROTARY STRUCTURE
Document Type and Number:
Japanese Patent JP2019052789
Kind Code:
A
Abstract:
To facilitate exchange of a member which is exhausted or consumed in a coupling device.SOLUTION: A rotary structure comprises a furnace body 2, a tire 3, and multiple coupling devices 4 which are arrayed in a circumferential direction of the furnace body 2 and attached to the furnace body 2 and the tire 3. The coupling device 4 includes: a pin mounting part 11 which is provided in the tire 3; a support pin 12 of which the portion closer to a proximal end is held in a movable manner by the pin mounting part 11 and the portion closer to a distal end protrudes insides in a radial direction of the tire 3; a pin receiving member 13 which is mounted to an outer peripheral surface 9a of a peripheral wall 9 of the furnace body 2 and receives a distal end side of the support pin 12; and an energizing part 14 for energizing the support pin 12 in a direction in contact with the pin receiving member 13. When increasing a diameter dimension by thermally expanding the furnace body 2, the increase is absorbed by a change in an insertion amount of the support pin 12 to the pin mounting part 11. Since the support pin 12 is not coupled to any other member, the support pin 12 that is exhausted or consumed can be easily removed and exchanged.SELECTED DRAWING: Figure 4
