Claims (1)

[Scope of claims for utility model registration] (1) Vertical Z-axis vibrators each fixed to a base;
It is equipped with a horizontal X-axis vibrator and a horizontal Y-axis vibrator, and the vibration table on which the test object is placed is vertically moved by the vertical Z-axis shaker and vertically by the horizontal X-axis shaker. A three-dimensional vibration testing device configured to vibrate in one direction in a horizontal plane and in another direction perpendicular to the one direction by the horizontal Y-axis vibrator, which has rigidity in the longitudinal direction and has vibration resistance. a Z-axis connecting means having flexibility in a direction orthogonal to the longitudinal direction and directly connecting the vertical Z-axis vibration exciter to the bottom surface of a recess formed at the center of the lower surface of the vibration table; an X-axis connecting means that has rigidity in the longitudinal direction and is flexible in a direction perpendicular to the longitudinal direction and directly connects the horizontal X-axis vibrator and one side of the vibration table; a Y-axis connecting means that is flexible in a direction perpendicular to the longitudinal direction and directly connects the horizontal Y-axis vibration exciter to another side surface of the vibration table that is orthogonal to the one side surface; a cylindrical vertical guide member that is fixed upright on a stand and has a hollow portion into which the Z-axis connecting means is loosely inserted concentrically; A cylindrical first guide part to be fitted and a second guide part protruding from the outer periphery of the first guide part.
a horizontal guide member having a guide portion, the second guide portion is slidably fitted in a guide space formed in the vibration table parallel to the upper surface thereof in the horizontal X-axis direction and the horizontal Y-axis direction. A three-dimensional vibration testing device characterized by: (2) A first guide member is provided on the outer circumferential surface of the vertical guide member, which is a sliding surface with the first guide portion of the horizontal guide member.
a second plurality of oil pats are provided on a second guide portion of the horizontal guide member, which is a sliding surface with the guide space of the vibration table, and an oil path formed in the vertical guide member; through which oil is supplied to the first oil pat, and through an oil passage formed across the outer circumferential surface of the vertical guide member and the inner circumferential surface of the first guide part.
The three-dimensional vibration testing device according to claim 1, wherein oil is supplied to the oil pads of the three-dimensional vibration test device.
