AI Technical Summary
Under extreme conditions, the fasteners between the vacuum chamber and the cladding module of a tokamak device may not be able to maintain a stable preload, leading to loosening of the connection structure and affecting the stability of the device.
A fastening assembly for a tokamak device includes a first connecting sleeve, a second connecting sleeve, a third connecting sleeve, a connecting bolt, a fixing block, and a locking block. The locking block and the connecting bolt are circumferentially fixed by means of a contact portion and abutment groove structure between the locking block and the connecting bolt to prevent the connecting bolt from rotating around the central axis and to prevent loosening.
It effectively prevents the connecting bolts from loosening, ensures the stability of the connection structure between the vacuum chamber and the cladding, and adapts to thermal cycling and vibration loads under extreme working conditions.
