Multiplate type damper with adjustable braking force employed viscous fluid

Abstract

Abstract PURPOSE:To make the rotational braking force of a damper adjustable by changing the pressure applied to the polyisobutylene or the like which is used as the elastic fluid for a rotational multiplate type damper. CONSTITUTION:A rotational multiplate type damper is constituted by placing alternately in the vertical direction through a movable shaft 2 a movable plate 6 which is rotatable together with the movable shaft 2, and a stationary plate 7, which does not follow the rotation, as well as keeping an elastic fluid A of polyisobutylene or the like in a casing 1. A hydraulic pressure adjustment screw 8 to apply pressure to the elastic fluid A is then screwed into the casing 1. If the screw 8 is screwed in, the density of the elastic fluid A becomes high, the elastic shearing resistance between the movable plate 6 and the stationary plate 7 increases and the rotational braking force of the movable shaft 2 becomes strong. If the screw 8 is unscrewed, the rotational braking force of the movable shaft 2 becomes weak.
