PURPOSE: A vibration compensator is provided to easily perform an overlapping angle control work of a mass by simplify configuration for adjusting an overlapping angle of the mass in order to adjust an amplitude of exciting force and to precisely control controlling force of a mass. CONSTITUTION: A vibration compensator comprises a casing(10), a first and a second rotation unit, and a driving unit. The first and second rotation units comprise a first and a second rotary shaft(21,31), arc-shaped first and second fixed mass(22,32), and arc-shaped first and second variable masses(23,33). The first and second shafts rotate in opposite directions from each other. The first and second fixed masses are fixed to the first and second rotation shafts and comprise a plurality of bolt fastening holes(22a,32a) in an edge. The first and second variable masses are rotatably installed at the first and the second rotary shafts and comprise a plurality of the bolt fastening holes in the edge. The driving unit is installed in the outside of the casing and rotates the first rotation unit at a determined speed. |
