Hao-card sliding bearings _ seismic sliding ball bearing slide ball bearing _ provided by Hao-engineering rubber. We are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) located at: Hebei Hengshui specializes in: grid bearings, bridge expansion joints, water stop, bridge bearings, rubber bearings, ball bearing steel bearing the thickness of the plane and spherical Teflon plates should not be used in less than 7mm, its back after surface activation treatment should be universal slide ball bearing, mounted and bonded on the base plate, the embedded depth of not less than the thickness of two one half, the deviation from the assembly clearance between the periphery of the groove of the base steel sheet and other requirements of the longitudinal slide ball bearing, the grease lubricant PTFE plate surface disposal storage tank, the arrangement and size. Teflon plate processing flat and curved surface contour deviation deviation, slide ball bearing when the object is smaller than the diameter of the deviation caused, stainless steel plate and stainless steel plate bearing the grassroots Office applications using inert gas welding connection After welding stainless steel plate and not the base steel sheet should be snug. Required thickness stainless steel plate welded structure flatness plane and spherical contour of the maximum deviation of steel bearing steel and machining tolerances should meet the design requirements of the drawings, unlabeled component tolerances, character and location should be based on the requirements, bearing steel castings should be prescribed Zhuge conduct ultrasonic testing, the quality requirements of steel castings for one, does not allow any cracks and honeycomb hollow. Pot rubber bearing force development, the successful solution of the rubber molding method bearing plate hole as bearing function, generally require stand there, such as dead load and live load vertical force supporting the function of the upper structure , and able to adapt to temperature changes, such as to produce concrete shrinkage rotational displacement level displacement function, adapt and produce rotational displacement load bearing function circuit design and support force caused by the live load deflection and torsion beam Block seismic performance and test methods slide ball bearing, through actual testing of Guangzhou-Shenzhen high-speed railway stone quasi-Trond and other projects can be summarized in the following conclusions. By calibration of the load bearing and field tests showed that the formation of the next board in the oil pressure control, the injection of special hydraulic oil from the hydraulic pressure reflect changes in the actual reaction force bearing method is very rational and efficient use, the class bearing force measurement accuracy can reach 1% bracket bearing capacity, due to the superstructure load bearing reaction force size by concrete shrinkage and creep, where the combined effects of the loss of voice and other factors, at some stage for reaction force caused by certain factors can be tested indirectly understand the factors that impact on the structure of the future on the basis of the measured force is expected to mount studies, further research using the bridge bearings to adjust the reaction force structure.
