Abstract

The invention discloses a viscous damper. The piston rod and the plug head are driven to slide by an external force, the piston rod drives the rotating disk and the threaded buffer cylinder to rotate, and the threaded buffer cylinder The rotation of the rotating disk is slowed down, and the sliding of the plug head drives the hydraulic oil into the outer storage tank, and pushes the resisting slide to slide, and squeezes the resisting spring during the sliding process, and the resisting spring The resisting sliding plate acts as a reverse thrust to push the hydraulic oil into the buffer chamber, thereby slowing down the sliding of the piston rod and avoiding damage to the damper when it is subjected to a large pulling force.

Description

technical field [0001] The invention relates to the field of viscous dampers, in particular to a viscous damper. Background technique [0002] At present, the damping channel of the viscous damper is generally set on the piston. When the piston moves, the damping medium passes through the damping channel on the piston to generate damping force. The viscous damper uses the interaction between the viscous fluid and the structural components of the damper to generate damping. A speed-dependent structural energy dissipation and shock absorbing device designed and manufactured based on the principle of force. [0003] Because the existing viscous damper usually uses the piston to squeeze the hydraulic oil inside the damper for damping and vibration reduction, because it is a one-way force damping, the piston rod will exert force on the outer shell of the damper when it is under tension, resulting in The piston rod of the damper cannot withstand a large pulling force, which may e...
