PURPOSE: A bridge bearing using a spherical bearing is provided to stably deliver a horizontal force by surface-contacting a pin and an anchor ring in the generation of a rotation displacement. CONSTITUTION: A bridge bearing using a spherical bearing comprises a center plate (100), a rotary disk (200), an anchor ring (300), a pin (400), a bearing set (500), a space ring (600), and a split ring (700). The center plate is equipped on the bottom surface of a top plate (1). The bottom side of the center plate comprises an accommodating groove (120). The rotary disk is equipped on the bottom surface of a middle plate to accommodate the rotary motion of the middle plate. The anchor ring is equipped on the bottom surface of the rotary disk and is fixed to a bridge post by the bottom part. The pin penetrates the rotary disk. The top and bottom sides of the pin are separately inserted into the accommodating groove of the middle plate and the anchor ring. The bearing set is equipped in the accommodating groove of the middle plate to support the rotation of the middle plate. The bearing set comprises a convex spherical bearing (520) and a concave spherical bearing (540). The space ring is equipped in the bottom part of the concave spherical bearing to support the concave spherical bearing. The split ring is equipped between the rotary disk and the anchor ring to flatly support the rotary disk. |
