Hao-engineering rubber _ steel hinge bracket _ 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, rubber sheet, bottom basin, foot 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 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, not destroy long steel pots, rubber board will not lose carrying capacity, so grid hinge bearing, ball bearing hinge more for large tonnage bridge support, while the rubber sheet is liquid at a similar functional three-dimensional stress state, rotating flexible to meet the amount requires end portion. According to experience, is about one tenth the thickness of the rubber plate diameter. Stainless steel plate is used as a two-way (or to) and one-way and one-way activity movable bearing slide bearing lateral sliders to use. Stainless steel pot bearings used material requirements are as follows: the requirement for stainless steel materials, chemical composition and mechanical properties which should be consistent with the relevant provisions of the steel surface shall comply with the requirements of the processing, surface hardness should be hv150-hv200, coastal bridges and cross sea ??bridge bearings with stainless steel plates preferred length monumental steel is generally less than or equal 1500mm, thickness using 2mm, stainless steel plate length greater than 1500mm, thickness using 3mm, stainless steel plate shall have layered surface without cracks, bubbles, impurities, scarring and other effects of the use of defects. Stainless steel plate and grass surface after welding plane culverts shall not exceed the maximum deviation of the maximum size of the PTFE plate 0.03%. As the use of Teflon plate bearing activities, often using grease lubrication, at present, the use of standard 5201-2 grease, while the grease must be tested to ensure the seat does not dry up in the temperature range, on the slip surface material may not be harmful, and has good resistance to ozone steel hinge bearings, corrosion-resistant and waterproof performance. Its physical and chemical performance indicators should be consistent with the relevant provisions. Important part of the fixed hinge steel ball bearing hinge support member, bearing bottom pots, plates and bearing on the middle of the roof is usually applied mold casting, machining tool path again to meet the design requirements. But also uses thick steel plate welded case processing, for which the relevant criteria are clearly stated requirements and make provisions.
