Abstract
A three-dimensional guiding apparatus is installed between the ground and a structure for preventing vibrations of the ground from being transmitted to the structure as much as possible. The three-dimensional guiding apparatus has a first curved guiding apparatus (21) mounted on a base (23), a second curved guiding apparatus (22) having a plane of movement which crosses the plane of movement of the first curved guiding apparatus (21), and an intermediate member (24) interconnecting the first curved guiding apparatus (21) and the second curved guiding apparatus (22). Each of the first and second curved guiding apparatus (21, 22) comprises a track rail (1) having a plurality of rolling element rolling grooves, a bearing block (10) having a plurality of rolling element rolling grooves and non-loading rolling element rolling passages, and a number of balls (9) for bearing loads between the rolling element rolling grooves in the track rail (1) and the rolling element rolling grooves in the bearing block (10). The intermediate member (24) has open cylindrical recesses (241, 242) defined respectively in two surfaces thereof, with the bearing blocks (10) being rotatably fitted in the open …
