The invention discloses an elevator vibration reduction device used for elastically supporting an elevator component needing vibration reduction. The elevator vibration reduction device comprises a rigid top plate, a rigid base, a first elastic part and second elastic parts. The rigid top plate is provided with a bottom, a top and a side. The rigid base is in a shell shape with the top opened andis provided with a bottom wall and side walls. The first elastic part is extruded between the bottom of a first rigid part and the bottom wall of the rigid base. The second elastic parts are extrudedbetween the side of the first rigid part and the side walls of the rigid base. Elastic supporting force, in the vertical direction, provided by the elevator vibration reduction device is decreased along with increase of elastic deformation, in the vertical direction, of the elevator vibration reduction device, so that the elevator vibration reduction device has the negative rigidity characteristic. In the elevator vibration reduction device, the dynamic rigidity of the elevator vibration reduction device in the vibration state can be infinitely small, and the vibration reduction effect is improved to the largest extent.

    本发明公开一种电梯减振器,用于弹性支撑需要减振的电梯部件。所述电梯减振器包括:刚性顶板,具有底部、顶部和侧部;刚性基座,呈顶部开放的壳体状,具有底壁和侧壁;第一弹性件,被挤压在所述第一刚性件底部和所述刚性基座的底壁之间;和第二弹性件,被挤压在所述第一弹性件的侧部和所述刚性基座的侧壁之间,所述电梯减振器所能够提供的竖直方向的弹性支撑力随所述电梯减振器在竖直方向上的弹性变形量的增大而减小,使得所述电梯减振器具有负刚度特性。在本发明中,电梯减振器在振动状态下的动刚度可以无穷小,最大限度地提高了减振效果。
