PURPOSE:To make it possible to install a reciprocating machine having a reciprocating motion element even on a high-storied floor, by providing an anti-motion element, which moves in the reverse direction with respect to a reciprocating element, to a vibration isolator of the reciprocating machine. CONSTITUTION:When a high-speed crank press 11 operates in order to move a slide 15 up and down, vibration occurs because of this operation. However, since a weight 18 is moved up and down in the reverse direction with respect to the slide 15 via a chain 17, the vibration energy accompanying the vertical motion of the slide 15 and that accompanying the vertical motion of the weight 18 cancel each other, the vibration can be prevented. In addition, since the main body 14 of the high-speed crank press 11 is installed on a fixed floor 12 via an air spring 13, vibration isolation by the air spring 13 is also carried out. As a result, installation of the vibration isolator on a high-storied floor such as the second or third floor, which has been considered impossible so far, becomes possible. |
