Sliding bearing is an important part of the design of spherical bearings, spherical plain is also crucial to the success of the site holder. Its main role is to overcome the eccentricity distance under various loads and control adaptation, during use to avoid the arcuate sliding surface of the eccentric distance is too large beyond the safe range, the arcuate sliding surface can be used instead of the plane, the decision result in the axial direction The total distance of the eccentric force should consider the role of internal forces and moments due to the friction generated at the curved sliding surface, sliding bearings and external horizontal load is processed and forwarded bearing needs requirements, and should be considered due to the limit Additional benefits resulting from the impact of the role. Calculating friction resistance type, sliding bearing friction coefficient can refer to the relevant standards adopted by the sliding surface surface separation constraints, the sliding surface of the separation will cause greater wear deformation, dust sealing measures coupled with the bad, sliding bearings will caused by dust, etc. should be cause long-term stiffness directly affects bearing service life, the state in the long-term effects can be taken into account when checking the long-term effects of internal forces under the combined effect of the view that the sliding bearings can be considered to form an elastic slip showing rather rigid bearing plate, slide bearings when the total eccentricity in the core area of ??the projection plane, this time should be to satisfy my demands, finished with a coefficient of horizontal load-way ball bearing slide, ultimate strength design corner filling , a quarter plate limit the maximum average contact stress under strong state. Sliding bearing concrete corner hinges may occur alternately positive and negative to double measure, even so, do not usually lose their security while finished bidirectional ball bearing slide, if the concrete is completely cracked neck hinges finished seismic ball type sliding bearings, single action can alternately closed down corner ball bearing slide, slide the hinge bearings can withstand all loads. According to reference, concrete hinge design method can be divided into one-way and two-way rotation of the rotary joint bearing hinge support analysis and calculation, the original concrete information on the calculation method described below hinge, unidirectional rotating hinge bearing concrete, concrete hinged neck area is calculated and judged OK. The maximum design load sliding bearings under constant load angle corner dead load calculation does not exceed the maximum compressive strength of concrete standard value 1.5n maximum design load and dead load ratio of sliding bearing, corner often happens, calculation of the coefficient, hinge-section the length of the short side.
