Stainless steel plate is used as a two-way (or to) and one-way and one-way movable bearing slide bearing lateral ball joints slider. Stainless steel material used ball bearing hinge requirements are as follows: the requirement for materials stainless steel, its chemical composition and mechanical properties shall comply with the relevant provisions of steel ball joint bearing surface shall comply with the requirements of processing seismic unidirectional sliding ball joint bearing, The surface hardness should be hv150-hv200, coastal and sea-crossing bridge with stainless steel ball bearing hinges preferred length immortal steel is generally less than or equal 1500mm, thickness using 2mm, stainless steel plate length greater than 1500mm, thickness using 3mm, ball joints branch seat stainless steel plate may not have stratification, surface defects may not have cracks, bubbles, impurities, scarring and other effects used. 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 a Teflon plate ball bearing hinges used, usually grease lubricated, ball joints bearing current seismic standards provisions adopted 5201-2 grease, while the grease must be tested to ensure that the use of bearing temperature do not dry up within the scope of the slip surface material may not be harmful, ball bearing hinge and has good resistance to ozone, corrosion-resistant and waterproof performance. Its physical and chemical performance indicators should be consistent with the relevant provisions. Important part of the ball joint bearing steel ball bearing hinge member, ball bearing hinge bottom basin seismic ball joints fixed bearing, intermediate bearing plate and the top plate is usually application-mold casting, machining tool path again 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. In the action (or load) maximum angle under the most unfavorable combination 0.02rad, this value should comply with the relevant provisions of the standard or given by the designer. Under the proper use of state poor corner, this value should comply with to have any standards, the general should meet the design requirements. Ball bearing hinge flip when changing variable rotation under load occurs, the variable rotation will cause the rotation of wear, ball bearing hinge will affect the seal durability. Turn the trajectory design range, according to the following formula should be determined according to the design requirements. The actual change in the scope of gray machine design vehicle load caused the number of bearing service life of the vehicle under the design seismic angle difference can move the ball bearing hinge, between the bottom of the basin diameter bearing amount, test and track the actual rotation range correction factor, usually five, rotation trajectory essay, ball bearing hinge foreign test data shown below. Pot bearing rotation constraints, and constraints caused by the rubber sheet caused by seals Huan moving, rubber sheet maximum restraint in accordance with the following provisions. Ball bearing hinge moment the biggest constraint generated, rubber plate diameter, permanent total use, variable-angle effect caused by the restoring moment coefficient at zero rotation; under constant load eccentricity, rubber sheet in case of no moment run test coefficient test device, using two pot bearings with a sliding surface of the test device, using a ball bearing hinge pot bearings with a spherical bearing static testing device. Rubber sheet average pressure, have restored the next moment coefficient rotation Run circumstances. Eccentricity, ball bearing hinge moment there are circumstances under run, no run case, recovery from the coefficient of rotation without profit situation. Ball bearing hinge on the roof at the bottom of the basin with a surface due to the friction generated additional moment should be considered, in order to determine the value of this moment, the bottom and the top surface of the ring basin largest coefficient of friction on ball joints should go 0.2 earthquake bearing | Factory 13833855982 | fixed seismic ball bearing hinge is provided by Hao-engineering rubber.
