Girder steel ball bearings _ _ Hao-engineered rubber damping steel ball bearings provided by the steel beam Hengshui HaoTong Engineering Rubber Co., Ltd .. Girder steel ball bearings _ _ Hao-engineered rubber damping steel beam steel ball bearings are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) this year launched a new upgrade, the above picture is only for reference, please call Phone or pictures on this page, for the latest information, contact: Liu. Ball bearings are usually divided into non-stiffening stiffening bearing two kinds of drink holder. Only one non-stiffening rubber bearing, at the level of force, although the level of rubber bearings to meet the needs of shear deformation, but bearing in vertical loads tend to produce vertical deformation. At this point, the ball bearings due to constraints is relatively small, and because the incompressibility of rubber, ball bearing deformation only sideways expansion, there will be a large rubber oil drum at a large convex pull in around it stretch deformation, resulting in stress aging. Such ball bearing on our roads and bridges is not recommended. In order to withstand large vertical loads can also meet the needs of horizontal displacement, the bridges are generally used stiffened laminated rubber bearings, ball bearings stiffening stiffening material can be steel, fiberglass, cotton, nylon cloth, single Our bridge stiffening material used for steel, other materials are not recommended, since as a stiffening plate rubber under vertical loads, steel embedded rubber sheet rubber between will limit the expansion of the convex side drum, vertical deformation is reduced accordingly, thus greatly improved vertical stiffness rubber bearings. At this time, the ball bearing vertical deformation of the total deformation will be the sum of each thin rubber sheet. Some manufacturers products are exported to foreign countries, mechanical properties testing requirements for foreigners saw our detection equipment, are reflected too far behind, so this standard rubber bearings are also made, using computer controlled test equipment should be capable of automatically and continuously smooth ball bearing steel truss girder load, unload, automatically collect test data, automatically drawing stress-strain curve and print test structures. Ball bearings so you can minimize human interference during operation, to improve detection accuracy, even if the current detection unit does not have to cover some of the testing methods, but the standard also suggested that if the project have such testing equipment girder ball steel bearings, ball bearings detection unit may send a corresponding detection methods of testing personnel qualification certificates to the factory supervision and inspection, this approach abroad is also permitted. Ball bearings and detection units should try to improve and update detection equipment to ensure the correctness of the serious type of law enforcement, the newly revised industry standard steel ball bearing steel girder detection structure, on the mechanical properties of the test methods and procedures loading, unloading speed, computational methods, experimental discipline etc made it clear that hope detection units, engineering expression of self-checking test results according to uniform regulations. Thus everyone a very clear, the ball bearing to old standards have requested Corridor steel ball bearing steel beams, but the units are not unified, the results are given some hard to look at it to understand. The ball bearing on the mechanical properties of the test requirements supplement the two, one is the rubber bearing shear bond test, an aging mount shear-type test, which is judged good or bad performance ball bearings Important indicators.
