Abstract

PURPOSE: To provide effective control on wide rotary-press flutter in low frequency by installation of a flutter protection on the stationary component of the press.
CONSTITUTION: A flutter protection is composed of projections 13, a mild nonferrous metal 14 and a plate spring 15, wherein a plurality of semispherical projections 13 on the upper horizontal plane of a bearing holder 11 supporting a spherical slide bearing 10 beneath a lower shaft 2 and a sponge-like, mild nonferrous metal 14 mounted on the tip of the plate spring 15 installed on the casing 6 is compressd to bring it into contact with the projections. When it subjects a casing 6 to the external force of an earthquake, etc. and causes a rotor 17 to flutter violently in low frequency, a soft metal piece 14 and a projection 13 vibrate and slide each other and the dynamic friction dissipates vibration energy of a bearing support 11 into heat energy, therebt controlling the vibration of the bearing support 11 and preventing the flutter of the rotor 17
