Support forces around forever deformed by Globe, can be released bi-directional movable seismic moment spherical hinge bearing, rotating torque has nothing to do with only spherical radius about the steel liner plate and bearing angle size, so the spherical bearing rotating torque Small, the current holder of the spherical ball joint angle can be used as 0.06rad and above, for large angle of bridge bearings. While rotating the pot bearing pot by deforming the rubber sheet need to adapt the beam angle, the ball bearing due to the rotation of the hinge the impact deformation of the rubber rubber plate diameter, thickness and hardness of the seat is rotated by means that, with the changing the seat angle, change the ball bearing hinge moment is the response, and the thickness of the rubber sheet with certain restrictions bidirectional seismic activity ball bearing hinges, rubber plate thickness under conditions restricted, pot bearings The design angle is generally less than 0.02rad, so the pot bearing rotation range of adaptation and flexibility yuan excluding spherical bearing, while the ball bearing hinge to rotate each performance has been, more suited to the occasion with a wide curved bridge and the bridge of use . Spherical bearings do not use rubber bearings under pressure so there is no reason to affect the British rubber aging 碧昂 ball bearing hinge rotation function problems, more suitable for use on low-temperature region bridge engineering. Spherical bearings do not use rubber pressure in accordance with national standards for the performance of spherical bearings do a bit of attention to several aspects of the basic requirements. Lower ball bearing hinge basic performance requirements of the role and then vertical design bearing capacity, ball bearing hinge vertical compressive deformation had to be greater than 1% of the total height of seat. Matters must be special attention before painting before painting the basic surface to be coated must be processed to reach the surface smooth and clean, is the key to ensure the coating quality. Otherwise, due to the substrate surface is not smooth, retained harmful substances, ball bearing hinge will seriously affect the adhesion of the coating slip bi-spherical hinge bearing, so that the coating peeled off prematurely and lose its protective effect. That is carried out prior to painting to perfect surface treatment, to enhance coating adhesion, better play the role of coatings to protect and prolong its life, plays an extremely important role. Ball bearing hinge protective effect is good or bad, it was considered one-third coatings, construction of six points, the extent of the visible surface treatment and fine construction directly affects the protective effect, according to the experiences, the basic surface treatment include the following. General use of organic solvent degreasing degreasing, chemical degreasing, ball bearing hinge electrochemical degreasing and emulsifying cleaning degreasing and other methods. The most commonly used organic solvents and degreasing chemical degreasing. Ball bearing hinge is the use of chemical degreasing grease saponification occurs in alkaline medium were removed by saponification oil, it is also called hot alkaline degreasing method, this oil works best two-way sliding seismic spherical hinge bearings, spherical earthquake Hinge Bearing, Hao-processing provided by Engineering Rubber Co., Ltd.
