MULTI-DEGREE-OF-FREEDOM SPHERICAL BEARING

摘要

PROBLEM TO BE SOLVED: To provide a multi-degree-of-freedom spherical bearing capable of adjusting angle of object to be retained, absorbing difference of distance and providing sufficient stiffness.;SOLUTION: The multi-degree-of-freedom spherical bearings 10, 18 are provided with a first member 11 having a concave spherical surface 23 formed inside thereof, an oscillating device 200 including a center sphere 12 of which outer circumference is oscillatably supported by the concave spherical surface 23 of the first member 11 for attaching a panel 30, a second member 22 in a fixed side, and a moving device 250 arranged between the first member 11 and a second member 22 and supporting the oscillating device 200 movably along a direction on X-Y plane crossing a center axis CL of the oscillating device 200.;COPYRIGHT: (C)2008,JPO&INPIT
