parts 5 and contacts with described the second rotatable parts 5, the other end of described the first rotatable parts 3 stretches out described shell 6 and is connected with described installing rack 2, and described elastomeric element 8 is arranged in described cavity.By shell 6 is set, can make damping rotary device form an entirety, the assembly relation between the first rotatable parts 3, the second rotatable parts 5 and elastomeric element 8 is more firm, and performance is more stable, assembles convenient.In the present embodiment, described elastomeric element 8 is stage clip, and described elastomeric element 8 is exerted pressure to described the first rotatable parts 3 so that form spin friction resistance between described the first rotatable parts 3 and described the second rotatable parts 5.One end of described shell 6 and described the second rotatable parts 5 are threaded connection, described shell 6 is provided with screw thread 61, described the second rotatable parts 5 are provided with screw thread 52, and the other end of described shell 6 is provided with end wall 62, and described end wall 62 is provided with the through hole passing for described the first rotatable parts 3.One end contacting with described the second rotatable parts 5 of described the first rotatable parts 3 is provided with tapered portion 31, and described tapered portion 31 is provided with the stress surface of the pressure for bearing described elastomeric element 8, and one end of elastomeric element 8 is resisted against on this stress surface.The tapered portion 31 of described the first rotatable parts 3 is arranged in the cavity that described shell 6 surrounds with described the second rotatable parts 5 and contacts with described the second rotatable parts 5, the other end 32 of described the first rotatable parts 3 stretches out described shell 6 and is connected with described installing rack 2, and described the second rotatable parts
