Membrane structure bearing _ _ Hao-engineered rubber membrane structure unidirectional sliding ball bearings provided by the Engineering Rubber Co., Ltd. Hengshui HaoTong. Membrane structure bearing _ _ Hao-engineered rubber membrane structure unidirectional slide ball bearing is Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) launched this new upgrade, the above picture is only for reference, please call this page or contact phone picture on to obtain the latest information, contact: Liu. Some manufacturers products are exported to foreign countries, mechanical properties testing requirements for foreigners saw our testing equipment, were too far behind to reflect a one-way membrane structure slide ball bearing, rubber bearing so this standard also proposed, test equipment should adopt computer control, can automatically and continuously smooth loading, unloading, automatic collection of test data, automatic 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 also raised the standard two-way slide ball bearing membrane structure, if it works have such testing equipment, ball bearings detection unit may send a corresponding detection methods of testing personnel qualification certificates to the factory supervision and testing, this method in foreign countries are allowed. 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 detection structure, on the mechanical properties of test methods, procedures membrane structure supports, loading, unloading speed, computational methods, experimental discipline etc made clear that fixed ball bearing type membrane structure, hoping detection units, engineering expression of self-checking test results according to uniform regulations. Thus everyone a very clear, the ball bearing to old standards is also required, but not all units unity, given the results of some hard to look 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. Make the choice of ball bearings except possibly transmitted vertical and horizontal reaction force, but also to adapt to deformation along the bridge and the transverse direction. Meanwhile, the choice of ball bearings should be made due to the superstructure longitudinal and transverse beam displacement and angular distortion arising from unfettered as possible due to temperature changes and other bridges, ball bearing load deflection, as a bridge bearing design The basic factor conditions, there is a reaction force (vertical force, horizontal force, a negative reaction force), in addition to seismic forces, such as ball bearings and other steel deck bridge small proportion of dead load, at a high sound insulation to avoid continuous sill points, sometimes due to wind loads produce maximum horizontal reaction force, but also sometimes due to temperature changes the level of reaction force generated by friction ball bearing rubber bearings to determine the cross-section. Displacement and the connection conditions of the three, ball bearings following items are described as the county should pay particular attention. Shrinkage and creep of concrete, prestressed members so elastic deformation caused by stretching and rotation of the beam
