Document Type and Number:
Japanese Patent JP2766835
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To form a unit by efficiently assembling various kinds of structural members to make easier the application into the required areas and to obtain outputs from both ends. SOLUTION: An annular vibration element 1, which is formed of an electrostrictive element or magnetostrictive element polarized in the thickness direction, equally divides the electrode in one surface side into a value x which is 2 or larger and generates a traveling wave force in the circumference direction by making use of expanding or compressing wave in the circumference direction by the application of an AC voltage showing deviation of the phase on the time axis of 2π/x in the circumference direction to each divided electrode, is provided at the lower or higher end of base 30. Moreover, a metal cylinder 6 is arranged on the vibration element 1, the metal cylinder 6 is fixed to the base 30 with a screw lever 8 provided in the vertical direction at the center thereof and the vibration element 1 is held between them as the pre- compression. Rotors 13, 32 are respectively provided on the cylinder 6 and at the vertical surfaces of the base 30. Thereby, the output shafts 16, 33 are supported by the bearings 17, 36 fixed at the upper and lower sides of the cylinders 18, 34 and thereby projected externally in the upper and lower sides of the cylinders 18, 34.
