Finished movable hinge support professional manufacturers | steel movable hinge support telephone | movable 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, ball bearing steel bearing press force limit state and serviceability limit state design striving to ensure that there is sufficient stability against sliding, ball joints when using seat anchor system usually pot bearings to ensure its stability, and stability of the bearing friction alone, should be the ultimate limit state checking its 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. The minimum displacement ball bearing hinge strength design, turn volume, turn the pot bearing has its certain range, national standards limiting the pot bearings have the largest turn angle, the ball bearing hinges are currently mostly The initial provision shall not be greater than steel movable hinge bracket telephone, single European standard of not more than 0.03rad, permanent variable relationship corner corner, the ball bearing hinge corner worth here permanently mounted front seat after operations caused corner, it can be said to produce a constant load angle, and live load operations generate relations between the corner. Design maximum angle, initial angle, the maximum angle variable load generated by the smallest corner of variable loads generated. Ball bearing hinge design, generally 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. Ball joints and horizontal bearing ball bearing hinge bearing non-slip direction shall not be less than 10% of the vertical bearing capacity, seismic bearing horizontal bearing capacity of not less than 20% of the vertical bearing capacity, and can withstand not less than vertical on 20% of the carrying capacity to uplift. Ball bearing hinge not applicable temperature range, bearing materials used in physical and mechanical properties of PTFE sheet, PTFE sheet PTFE sheet bearing use, should be used fresh pure material molded displacement of 50mm Seismic movable hinge bracket, you can not use cutting boards, you should not use recycled materials, embossed sheet material back, look at the average particle size of poly tetrafluoroethylene sheet material shall not be greater than 50mm, molded PTFE pressure should not be less than 30mpa physical and mechanical properties of ethylene board. Monumental steel ball bearing hinges used, the use of materials such as technical conditions are met adjustable ball bearing hinge movable hinge bearings, tension and compression drink holder designed for use on the bridge of the basin earthquake zone seismic rubber bearings, spherical shock Supports and LRB and other movable hinge bracket to order, these are almost always the patented product, it can be expected soon will be valid for use on bridge engineering, while monitoring the quality of bridge engineering work also continue to strengthen, the experimental study of the dynamic performance of ball bearing hinges are also emerging to make bridge bearings better meet the needs of highway bridge construction.
