Spherical bearing comprises upper bracket plate 1, middle seat board 3, lower seat board 5, plane tetrafluoro plate 2, sphere tetrafluoro plate 4 and side direction block 6; Plane tetrafluoro plate 2 is located between upper bracket plate 1 and middle support plate 3, and the friction factor between itself and upper bracket plate 1, middle seat board 3 is all very little, thereby can realize the horizontal slip of bearing; Sphere tetrafluoro plate 4 is located between middle support plate 3 and lower seat board 5, and the friction system between itself and middle support plate 3 and lower seat board 5 is also all very little, thereby realizes being free to slide and rotating of bearing; Lower seat board 5 is fixed in the high-damping rubber base that is positioned at bottom, relatively transfixion; Side direction block 6 is arranged at the outward flange of upper bracket plate 1, and its sagging degree of depth enough touches lower seat board 5, thereby can stop the scope of activities of upper bracket plate 1, limits the over-large displacement of bearing.
High-damping rubber base comprises upper plate 8, lower plate 13, high-damping rubber layer 10, some reinforcement steel plates 11, rubber cover 12, and each is strengthened steel plate and flatly inserts high-damping rubber layer 10 inside, and whole high-damping rubber layer 10 is positioned in the middle of two upper and lower plates; High-damping rubber layer 10, reinforcement steel plate 11, rubber cover 12 are integral by sulfuration process, form column, and rubber cover 12 is positioned at the periphery of whole column, and the high-damping rubber layer 10 of its inside, reinforcement steel plate 11 are had to protective effect; Upper plate 8, lower plate 13 respectively by connecting bolt 9 and high-damping rubber layer Shang Xia 10 both ends of the surface fix.
Together with lower plate 13 is anchored on base-plate 14.
Plane tetrafluoro plate and sphere tetrafluoro plate be pure tetrafluoro plate, fill in tetrafluoro plate or modified ultra-high molecular weight polyethylene plate any.
Preferably, strengthening the steel plate number of plies is 2 ~ 6 layers.
Function of the present utility model and working method:
1, under normal use, be used as freely movable bearing, meet the requirement of normally using: by being free to slide between the spherical bearing upper bracket plate with horizontal slip face and middle support plate, can adapt to the horizontal movement requirement under the normal use of bearing, the corner under the normal use of bearing requires to realize by the shear strain of spherical bearing rotation spherical and high-damping rubber base.
2, under geological process, be used as vibration absorption and isolation support, subtract shock insulation mechanism simple, effect is stable, reliable: under geological process, when the horizontal movement of bearing is greater than the horizontal movement that block limits, high-damp rubber support can continue to occur shear strain power consumption, realize the effect that multiple tracks subtracts shock insulation, utilized the highly energy-consuming characteristic of high-damping rubber material.
The beneficial effects of the utility model are: simple in structure, realize effective combination of spherical bearing and high-damping rubber material, both brought into play the good advantage of the large energy-dissipating property of high-damping rubber material damping, the function such as can utilize again spherical bearing horizontal slip, rotate, automatically reset.The horizontal movement of compound support relies on spherical bearing, and damping energy dissipation relies on high damping material, reaches good damping and isolation effect.
