VIBRATION DAMPING APPARATUS CAPABLE OF CONTROLLING THREE SHAFT DIRECTIONS, WHICH CAN REDUCE VIBRATION OF VARIOUS DIRECTIONS WITH ONE VIBRATION DAMPING APPARATUS

摘要

PURPOSE: A vibration damping apparatus capable of controlling three shaft directions is provided to reduce vibration flexibly corresponding to vibration property of various directions because a rotary shaft of an eccentric mass body can be changed.;CONSTITUTION: A vibration damping apparatus capable of controlling three shaft directions comprises a main body(5), rotary shafts(6), and driving units(8). The main body is connected to a structure including a vibration source. The main body is coupled to an output terminal of a rotation driving unit(9) and moves the rotary shafts having an eccentric mass body(7). The rotation driving unit has a driving shaft(10) crossing with the rotary shafts at right angle. The rotary shafts are installed in the main body and have the eccentric mass bodies. The driving units rotate the rotary shafts.;COPYRIGHT KIPO 2012
