Hao-engineering rubber, universal ball bearing hinges, Xining ball bearing hinge is 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 Supports commonly used with neoprene rubber sheet, natural rubber and EPDM rubber as a raw material, and prohibited the use of recycled rubber vulcanization process coriander live, the ball bearing type hinge bearing in normal use neoprene rubber sheet, cold type bearing rubber sheet made of natural rubber or EPDM rubber. Rubber sheet rubber with physical and mechanical properties. Teflon plate in ball joints just to commercial use of the seat, but also the need for strict use of Teflon sheet requirements, provisions should be eye-pure material molded, cutting boards should not be used in the relevant standard, Do not use more recycled materials, back chat embossed sheet, Teflon fill an average particle size of the raw material is greater than 50, the pressure should go to the top molding tetrafluoroethylene dollars depending on the type of raw materials, in general, should not be less than 30mpa universal ball bearing hinges, physical memory performance PTFE molded plate. Pot bearings with PTFE board design should allow pressure to 0mpa. Fabricated Teflon bearing plate and embedded in the gap between the slots according to their diameter size control in 0.5-1.0mm PTFE sheet surface should be smooth, not allowed to have a crack, dress, layered, does not allow impact damage and other mechanical defects, do not allow any entrained impurities. Meanwhile, the sliding surface of the Teflon grease board a plane should not stored fat storage tank and the size is not specified. By striving for the ultimate limit state and serviceability limit state design to ensure there is sufficient stability against sliding, usually basin using anchoring system to ensure its stability HX bearing lateral sliding ball joint bearing, while relying on friction stability ball bearing hinge bearing, the bearing capacity limit state should be checking their stability against sliding. Between the features and the safety factor is generally used for checking steel plate and friction coefficient, there is a reasonable amount of displacement of the surplus, the surplus amount, whichever rotating hinge great. Slide the surplus amount of vertical and horizontal is 20mm, maximum sliding direction, horizontal 20mm, this provision only for displacement ability to design, can not be used to calculate the stresses. Minimum displacement strength design, turn volume, turn the pot bearing has its certain range, national standards limiting the pot bearing rotation angle has the largest, most currently prescribed should be no more than a single European standard provisions may not be greater than 0.03rad, permanent relationship variable angle corner, where the corner is worth a permanent installation operations after the initial angle caused by the former holder, it can be said corner dead load, live load and operations generated between the corner relationship. Design maximum angle, initial angle, the maximum angle variable load generated ZX longitudinal sliding ball joint bearing, variable load generated by the smallest corner. Bearings are generally designed to be controlled by the following conditions. In the role of the most unfavorable combinations of maximum angle, this value should comply with the standards prescribed or given by design.
