In the action (or load) maximum corner under the most unfavorable combination 0.02rad bidirectional slide hinge bearings, this value should comply with the relevant provisions of the standard, or given by the designer. Use the correct angle poor state, this value should comply with to have any standards, the general should meet the design requirements. Variable rotating ball bearing hinge flip appear under changing loads, variable rotation will cause the rotation of the wear, the ball bearing hinge seals will affect durability. Turn the track design range, according to the following formula should be determined in accordance with design requirements. The actual range of gray machine design changes caused by vehicle load, the number of bearing service life of the vehicle is subjected, poor design angle, the amount of the correction factor unidirectional sliding hinge between the end of the basin diameter bearings, test and track the actual rotation range bearing, usually 5, turn track essay, ball bearing hinge test data shown abroad. Turn the pot bearings constraints and constraints caused by the rubber plate seals caused Huan moving, rubber sheet maximum restraint in accordance with the following provisions. Ball bearing hinge moment biggest constraint produced rubber plate diameter, permanent total use, variable angle effect caused by restoring moment coefficient at zero rotation; under constant load eccentricity, rubber sheet in case of no moment-run test factor test set, using two pot bearings with a sliding surface of the test device, using a ball bearing hinge pot bearings and spherical bearing a static test device. Rubber sheet mean pressure, there are restoring moment coefficient is rotated under moist conditions. Eccentricity, ball bearing hinge moment there is under-run case, no-run case, the recovery factor from the rotation without Run circumstances. Ball bearing hinge on the bottom surface of the basin and on the roof of an additional moment due to friction should be considered, in order to determine the value of this moment, the bottom ring and the top surface of the biggest pots of the friction coefficient of 0.2 on the ball joints should go bearings are used in bearing structure with isolation function at the use in ball bearings at the hinge, generally adopt LRB or rubber bearings, namely isolation and damping integral damping rubber bearings. Ball bearing joints such as the use of shock absorbing structure can make the bridge deformation properties and energy absorption increased simultaneously. Can also contribute to multi-span continuous and seamless development. Each ball bearing hinge parts should be kept intact, clean hinge support, at least once every six months, remove oil bearing around, garbage, prevent water, snow, to ensure normal work stand. Rolling bearing rolling surfaces should be regularly painted oil, oiled before, ball bearing hinges should be rolling surface clean. Ball bearing hinge to be rust corrosion. In addition to the hinge axis and the rolling surface, the rest should be made part of the anti-rust paint brush, ball bearing hinge timely tighten bolts steel bearing combination ministries, the support plate smooth and firm. Finished fixed hinge bearing, bearing hinges Henan, where the production hinge support? Hengshui Hao-Hao Tong provided by Hengshui Rubber Company. Hengshui Hao-Engineering Rubber Co.
