Anti-vibration coupling rod for cylindrical vibration damping device and vibration damping coupling rod using the same method of manufacturing a vibration-proof connection rod

摘要

Anti-vibration connecting rod cylinder with a novel structure that can be easily attached to the rod body while ensuring freedom of tuning and durability of vibration-proof characteristics while adopting a structure in which the rod body is attached to the inner shaft member An object of the present invention is to provide a mold vibration isolator, an anti-vibration connecting rod using the same, and a method for manufacturing the anti-vibration connecting rod. The inner shaft member 12 has a structure in which a first connecting member 20 and a second connecting member 22 are overlapped and inserted into a sleeve member 18 to which a main rubber elastic body 16 is fixed. A rod end insertion space 72 is formed between the first and second connecting members 20 and 22 inserted into the rod 18 and is inserted into the rod end insertion space 72 through the rod insertion holes 24 and 46. Is fixed to the first and second connecting members 20 and 22 by a fastening member 90, and the first and second connecting members 20 and 22 are respectively attached to the rod body 74 by the fastening member 90. It was made to abut.
