Hao-engineering rubber _ Corridor sliding bearings _ sliding 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, ball bearing steel bearing The attendance sheet, lower seat plate longitudinal sliding bearings, spherical steel liner panels middle if the use of steel, steel plate shall comply with the relevant requirements, bearing attendance sheet, Xiazuo board, after all spherical steel liner plate when the use of a steel casting , its chemical composition, mechanical properties and impact toughness after heat treatment shall comply with the relevant requirements, the use of a seat in the workpiece machining, welding technology should meet the relevant requirements, spherical steel liner plate processing Corridor spherical sliding bearings spherical bearing intermediate spherical steel processing contractor if plated drop handle type, not just with the grassroots surface voids, shrinkage cracks, scars, plating thickness not less than 10mm, should meet the requirements, the surface roughness is inevitable, and when the use of a welding package, monumental steel should meet the requirements, and the surface should not be wrinkled, liner and dense grass should be posted, without void phenomenon, and should ensure that the degree of tolerance of the spherical surface contour . Requirements adhesive binder is insoluble and thermal fixity, its quality is relatively stable, bond PTFE sheet and peel strength should not be less than the required just 5km, size and deviation, Teflon plate sliding surface is spherical support an important part of the seat design, but also the key parts of the spherical bearing success. Its main role is to overcome the eccentric load generated from a variety of control and adaptation, the process avoids the use of the arcuate sliding surface of the eccentric distance is too large beyond the safe range, a plane can be used instead of the curved sliding surface, the decision result in the axial The total distance of the eccentric force, should consider the role of internal forces and moments due to the friction generated in the curved sliding surface, and the external is processed horizontal load and bearing needs care requirements, and should also consider the role of lead due to the limit Additional benefits affected. Formula to calculate friction resistance, the friction coefficient can refer to the relevant standards adopted restrictions sliding surface surface separation, separation of the sliding surfaces will cause greater deformation wear, dust sealing measures coupled with the poor, and other causes because of dust into the cause long-term stiffness directly affects the life of the finished bearing slide bearing, the state in the long-term effects can be taken into account when checking the long-term effects in the integrated internal forces believe that may be considered slip showing shaped flexible, and bearing plate rigid state, when the total eccentricity within the core area of ??the projection plane, this time should be to satisfy my requirements, with coefficients of horizontal load, ultimate strength loading design corner, the limit of strong state quarter panel maximum average contact stress.
