Title:
VIBRATION RESTRAINING DEVICE OF GEAR
Document Type and Number:
Japanese Patent JP2008223798
Kind Code:
A
Abstract:
To provide a vibration restraining device capable of sufficiently coping even with large vibromotive force, and superior in durability.
This vibration restraining device restrains vibration caused by transmitting torque between these gears by rotating by mutually meshing a driving gear 1 with a driven gear 2. A piezoelectric element unit 3 arranging electrodes 8a and 8b on both obverse-reverse surfaces and generating voltage in response to stress, is arranged in an annular ring shape on at least one side surface in at least any one gear of the driving gear 1 and the driven gear 2, and a circuit 9 is arranged for reducing an electric potential difference in these piezoelectric element units 3.
