Foreword
The standard reference European standards EN1337-7 bearing structures - Volume VII "spherical and cylindrical surface of polytetrafluoroethylene (PTFE) seat"
(2001), EN1337-2 bearing structures - Volume II "sliding member" (2003) and AASHTO-LRFD "Highway Bridge Design Regulations
Fan "(2004) and other standards.
This standard replaces GB/T 17955-2000 "ball bearings technical conditions." This standard and GB/T 17955-2000 main difference compared to
Differences are as follows.
--- Bearing design bearing capacity is increased from the original maximum 30000kN 60000kN (see 3.3.1);
--- Increase the one-way bearing activities lateral displacement limit regulations (see 3.3.2);
--- Adjust the bearing angle classification (see 3.3.3);
--- Polytetrafluoroethylene sheet improves the performance requirements (see 4.2.1);
--- Improving the surface roughness of stainless steel, an increase in severe corrosive environment of the bridge with a stainless steel plate material requirements (see
4.2.3);
--- Increasing the convex spherical ball cap liner handle the technical requirements (see 4.2.5);
--- Increasing the overall plate PTFE plate and split the block number of requirements, increase the size of the deviation request (see 4.3.1.1);
--- Adjust the surface contour tolerance PTFE molded plate surface flatness tolerances and surface (see 4.3.1.3);
--- Increasing the spherical bearing surface coating protection requirements (see 4.5.1);
--- Complement ball bearing assembly requirements (see 4.6);
--- Proposed overall bearing vertical bearing capacity of the test should be carried out, the level of capacity, coefficient of friction and rotational behavior test (see 5.2.3);
--- Complement ball bearing installation conservation requirements (see Chapter 8);
--- Increasing the bearing capacity of bearing vertical and horizontal bearing capacity test method (see Appendix A and Appendix B).
