PURPOSE:To check any vibration transfer at a resonance point as well as to improve the extent of vibro-isolability at a high-frequency area by sealing a magnetic fluid in a cylinder, attaching a permanent magnet to a piston, and installing an AC magnetic field generating coil circumscribed to the cylinder. CONSTITUTION:A damper gear is made up of combining a piston 1 and a cylinder 2 together. The cylinder 2 consists of a nonmagnetic material, and a magnetic fluid 12 is filled up in the inner part, while the piston 1 has a permanent magnet 3. In the cylinder 2, an AC magnetic field generating coil is set up after being circumscribed to it. The damper gear is combined with a spring element 4 in parallel and connected to an interval between an exciting source 6 and a damped body 5. Thus, any vibration transfer at a resonance point is checked, and vibro-isolability at a high-frequency area is largely improvable. |
