Seismic steel ball bearings (bearings flat, curved seat, rocker shaft bearings and roller bearings): force transmission through the bearing steel contact surface, bearing displacement primarily through steel and steel rolling to implementation. PTFE sliding bearings: the holder by Teflon and stainless steel (or chrome-plated steel) plane (or surface) sliding displacement to meet the needs of bearing; rubber bearings (laminated rubber bearing , pot rubber bearing, PTFE laminated rubber bearing): The bearing force transmission through the rubber sheet to achieve. Teflon bearing plate by sliding displacement or rubber shear deformation to achieve. Rubber bearing angle by deformation or compression slide surface is achieved. Is a high stress bearing structural components. Concentrated load on the member acting on a small area through the cradle. Roller bearing reaction force through the rollers in contact with the rolling plane power transmission line section, power transmission line produce significant stress concentration, thus requiring the contact surface can withstand the high contact stresses. The reaction force transfer laminated rubber bearing, rubber bearing basin, PTFE laminated rubber bearings and ball bearings and other bearings, by plane (or surface) surface contact power transmission SJGZ seismic spherical steel bearing, smooth power transmission does not occur out of Ali necking route, so it is a reasonable way to transfer power. Seismic steel ball bearing steel ball bearing seismic performance is set viscous dampers on both sides of ordinary laminated rubber bearing activities, and when using a ball bearing steel bearing normal temperature bridge beam displacement due to temperature change bit slow, viscous dampers almost no resistance to displacement, and in the earthquake, viscous dampers in the role of rapid earthquake forces, hardly displaced, will have a significant displacement of the seismic resistance TGQZ steel ball bearings In this case the bridge bearing activities into a fixed bearing, so that all the piers of the bridge to bear the full force of the earthquake, achieve the purpose of shock absorption. Viscous damper damping medium, usually using ultra-high viscosity silicone oil, to prevent leakage. Seismic steel ball bearings in general by the cylinder, piston and damping materials, the piston in the cylinder reciprocating do JQGZ-II seismic steel ball bearings, have adequate holes on the piston, cylinder built with viscous material. Structure under the action of earthquake seismic force and viscous dampers work together with the structure of import rod force, pushing the piston movement of the piston on both sides of the damping material produces a pressure difference, the damping medium through the orifice, resulting damping force, to energy dissipation purposes. The internal structure of the damper varies, the speed index is generally between 0.1 to 1.0. Also damping force also with the piston area, the orifice size and length, cheer frequency, temperature, and other factors related to the damping material category. Viscous dampers and PTFE sliding bearing combination is also a common relief isolators.
