Alternatively, the axial direction projected area of the bottom support base 71 is larger than the axial direction projected area of the second damper ring wall 60. Thus, when the second damping ring wall 60 vibrates and sinks to the stroke limit along the axial direction, the first end 11 is abutted against the bottom support base 71, and noise caused by direct collision of the first end 11 with the fixed mounting surface is avoided.
The damping callus on sole still includes bottom connecting cylinder 72, the one end of bottom connecting cylinder 72 with inner edge 61 is connected, the other end of bottom connecting cylinder 72 with bottom supporting bench 71 is connected, just the axial direction projection area of bottom connecting cylinder 72 is less than bottom supporting bench 71's axial direction projection area.
Specifically, the utility model provides a damping callus on sole adopt rubber material integrated into one piece to be holistic flexible member, that is, elastic deformation can take place for the whole homoenergetic of damping callus on the sole, converts vibration energy into deformation potential energy and hot internal energy to supplementary realization noise elimination falls the purpose of making an uproar. Additionally, the utility model provides a damping callus on sole can also adopt nylon material integrated into one piece to be holistic flexible component, perhaps adopts epoxy material integrated into one piece to be holistic flexible component.
Specifically, in order to enhance the mechanical strength of the supporting cylinder 10, that is, the supporting rigidity of the supporting cylinder 10 for the vibrating body, at least one reinforcing ring platform 81 circumferentially disposed on the inner sidewall and/or the outer sidewall of the supporting cylinder 10 is disposed on the supporting cylinder 10. The utility model discloses in the damping callus on sole of embodiment one, the quantity of beaded finish platform 81 is one to this beaded finish platform 81 deviates from the side end face of connector 30 and the terminal surface parallel and level of first end 11, beaded finish platform 81 deviates from the terminal surface butt fixed mounting face simultaneously of side end face and the first end 11 of connector 30, has increased the area of contact between damping callus on the sole and the fixed mounting face, makes the damping callus on the sole can be more stable install on fixed mounting face.
The fastening member inserted into the through hole 1 has a clearance with at least a part of the wall of the through hole 1, that is, the fastening member is in clearance fit with the through hole 1. In this way, when the vibration body is excited by vibration energy generated during operation of the vibration body, the fastening member can perform damping displacement in the gap between the fastening member and the hole wall of the through hole 1 during vibration displacement in the circumferential direction and the radial direction following the vibration body, and then the fastening member transmits the vibration energy to the connecting body 30 in the circumferential direction and the radial direction.
