Introduction of bridge spherical bearing:
Ball bearing is a bearing plate, the bearing plate, ball core, ptfe board (F4, spherical four fluorine board) and the rubber ring basin of a special type of bearing products.Tub it will support the middle plate and rubber ball core and instead of spherical four fluorine board named, because LQZ ball bearing basin of the middle plate and bottom also correspondingly into a sphere, reduced the coefficient of friction.

The plane displacement by the bearing plate and plate for sliding between the four fluorine.In setting guide groove on the bearing plate on or guide ring to support the restriction of unidirectional and multidirectional displacement, can be made into spherical one-way active support, support and fixed support garment.Through ball core and spherical sliding between four fluorine board to meet the needs of the bearing Angle.

Features of bridge spherical bearing:
Ball bearing force, reliable and flexible rotation, not only have GPZ bearing capacity big pot rubber bearing, the characteristics of great seat to move, and can better adapt to the need of large Angle, compared with the ordinary Pot Bearing has the following advantages:
1, steel ball bearings with spherical force, there will be no force of necking phenomenon, the effect on concrete reaction was homogeneous;
2, ball bearing by spherical teflon plate of the sliding bearing of the rotation process, rotational torque is small, and rotational torque and pedestal only spherical radius and friction coefficient of ptfe plate, has nothing to do with bearing Angle size, especially suitable for large Angle requirement, design Angle can reach 0.05 rad.
3, LQZ ball bearings to the same rotation speed, is suitable for wide bridge, curved bridge;
4, this kind of bearing products without rubber pressure, there is no rubber aging effect on the properties of bearing rotation, especially suitable for low temperature regions.

The characteristics of the spherical bearing:
Ball type rubber bearing is reliable in force, to turn the consistent performance, not only have the pot rubber bearing the characteristics of the bearing capacity big, horizontal displacement, and can meet the needs of the large Angle, is suitable for wide bridge, curved bridge.Due to the pressure parts do not use the rubber parts, there is no rubber low temperature brittleness, etc, therefore particularly suitable for low temperature area.This series of standards as: GB/T17955-2009 Bridges ball bearing.

Ball bearing installation method and matters needing attention:
1, when my company production of ball bearing in the factory, has been the support level, and screw down the connecting bolt, in order to prevent the spherical bearing rotation occurred during the installation process and capsized.We can design according to user needs the preset Angle and displacement, but the construction unit shall be made before ordering the preset Angle and displacement demands, by the manufacturer in advance to adjust when it is assembled.
2, bridge construction units installed in front can be out of the box, and check the packing list, including spare parts list, the copy of inspection report, ball bearing product certificate and bearing installation maintenance conditions.When unpacking the case, the construction unit shall not be any rotating joint bolt, and shall not be arbitrarily remove bearing.
3, for ball bearing in the installation, the installation height should meet the design requirements, to ensure that in the plane of the bearing and is flat and level.Corners of ball bearing supporting surface elevation difference shall not be greater than 2 mm.
4, bridge maintenance unit bridge bearings for strict inspection regularly every year, removal of dust and debris near spherical bearing, and cotton silk carefully wipe dust on the surface of the stainless steel, to ensure that can be used.

Ball bearing technology performance:
1, LQZ ball bearing according to reaction (hard) to the bearing capacity can be divided into 29 level (kN) : 1500200 0250 0300 0350 0400 0500 0600 0700 0800 0900 0100 00125 00150 00175 00200 00225 00250 00275 00300 00325 00350 00375 00400 00450 00500 00375 00600, 00.
2, the ball bearing design Angle is divided into 5 levels: 0.02, 0.03, 0.04, 0.05, and 0.06 rad.
3, ball bearing displacement: two-way activity bearing with one-way bearing the main displacement direction of displacement is divided into 6 level (mm) : 50, plus or minus + 100, + 150, + 200, + 250, + 300, two-way activity horizontal displacement of support for + 40 mm, one-way activity bearing transverse displacement limit of + / - 3 mm. The displacement quantity may be adjusted according to actual needs.
4, design of ball bearing friction coefficient under the condition of the teflon plate with silicon grease lubrication, stress is about 30 mpa, the values are as follows: under normal temperature (25 ºC ~ + 60 ºC) 0.03;Low temperature 40 ºC ~ + 40 ºC (-) 0.05
5, LQZ ball bearings can withstand the horizontal force: longitudinal movable support (ZX) cross the bridge to the horizontal force for counteracting force of 10%;Fixed support (GD) 10% of the horizontal force for counteracting force.
