Specific embodiment
The present invention will be described in detail With reference to embodiment.
The present invention relates to a kind of segment bolt structures for resisting vibration loads of train stress relaxation, including arch screw bolt 1, pipe
Piece nut 2 and stress relaxation-resistant gasket 3.Arch screw bolt 1 includes arc screw rod 101, and 101 one end of arc screw rod is nut 103, separately
One end is provided with screw thread 102；Section of jurisdiction nut 2 and stress relaxation-resistant gasket 3 are installed on the screw thread portion of arch screw bolt 1, resistance to stress pine
Relaxation gasket 3 is close to section of jurisdiction nut 2 in inside；3 two sides of stress relaxation-resistant gasket is provided with damping tip surface 302, and section of jurisdiction is close in inside
Frictional force is formed, outside is close to section of jurisdiction nut 2 and forms frictional force.Nut 2 center in section of jurisdiction is interior wire hole 202, and outside is outer six rib
201。
Flexible gaskets 4 are provided at the nut 103 of arch screw bolt 1,4 center of flexible gaskets is flexible gasket perforation 402, ring
It is placed on outside arc screw rod 101, is close to nut 103 in inside, section of jurisdiction is close in outside.Flexible gaskets 4 are rubber washer.
