Abstract

PURPOSE:To stabilize the rotation, by providing plural small holes for air flow in the side face of outside circumferential parts of spacers of plural built-up flexible discs which are isolated from one another by plural spacers provided with air paths in the direction of the radius. CONSTITUTION:Spacers 2 and discs 1 between side plates, which are not shown in figure, in both sides are constricted by a guide bolt 4 and are made into one body. Air which has the pressure controlled is flowed into a hollow space 8, which is provided in the center of the laminated material, from the external. Several small holes 9 are provided in the side of outside circumferential parts of spacers 2. Controlled compressed air which is flowed into the hollow space 8 passes through air paths of respective spacers 2 as shown by arrows A and is fed to gasp 10 between discs 1. Even if a pressure difference occurs in each gap 10, air is flowed in the axial direction by small holes 9 as shown by an arrow B, and pressures in respective gaps 10 are equal to one another, and the force to deform discs 1 disappears. Thus, gaps 10 of discs 1 are kept constant to stabilize the rotation.
