Hao-engineering rubber, movable hinge bearing, Zhoushan hinge support 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, spherical steel ball bearing hinge structure bearing, ball bearing hinge-way (or to) the one-way bearing activities movable bearing drink from the roof (including the roof and stainless steel slide), PTFE slide, middle plate, seal rubber plate bottom pots, anchor bolts and other components of the dust cover, jelly direction along the one-way bearing activities also each have a guide dog, from the roof fixed bearing, seals rolling pin hinge, rubber sheet, bottom pots, anchor bolts and other components of the dust cover. Bottom basin, usually cast steel or steel plate welded steel pots (but welded steel bearing basin approach is generally limited by) the end of the basin is mainly used to constrain the deformation of the rubber sheet. Pot ring thickness, according to the measured pressure rubber sheet formula calculated according to the posterior wall of tact. The thickness of the basin, should be determined according to local bearing strength of the pelvic floor. Rubber sheet, rubber plate used to transfer reaction force elastic hinge bearings, rubber sheets are sealed in the spray tank, out of the three-dimensional stress state, therefore, the bearing capacity of up to improve, as long as the steel pan is not damaged, rubber sheet will not lose carrying capacity, so more suitable for large ball bearing hinge tonnage bridge bearings, while the rubber sheet is liquid at a similar functional three-dimensional stress state, rotating flexible to meet the needs of the end portion of the amount . According to experience, is about one tenth the thickness of the rubber plate diameter. Vertical deformation is usually determined by the test method, load distribution component generated to determine the load distribution generated when the component diffusion angle of 45 degrees and a maximum of 60 degrees, combined with the sliding member, consider the combined effects of activities hinged bearing Block, the basic structure and design of geometric parameters pot bearing checking, rubber sheet, the compressive stress resulting rubber sheet rubber sheet can be used to determine the diameter determined by the following formula; design vertical force, rubber sheet resistance design value of the movable hinge bearing, compressive strength value rubber sheet to take domestic standards prescribed allowable stress values ??25mpa, material partial factor, the recommended value of 1.3, the diameter of the rubber sheet, rubber sheet thickness dimension should be considered in a constant, live produced under the influence of a combination of loads caused by the deflection angle of the total, equal to 15% of its value is greater than the thickness of the rubber sheet, the basic assumption steel bottom basin designed bottom pot bearing basin, should now rarely used by welded, usually turning the whole cast molding. Design stress of the end of the basin, under the combined effect of the basic, any vehicle surface should not exceed the yield strength of the steel bottom basin set of parameters, if shown, bottom basin design has the following basic assumptions. Calculation model should include a bottom basin, fittings and installation of equipment required boundary conditions. Static characteristics assumed to have the rubber sheet under pressure. At the level of the applied force, the pressure on the top or bottom of the basin between the director of the ring and the plate is assumed to generate a parabolic distribution on half of the circumference, and its value is taken as the average of 1.5 times. When using the ring and the bottom end of the basin basin separate guardianship calculated minimum thickness of 12mm spray
