Hainan ball bearing, Hao-quality conquer the world, damping ball bearings provided by Hao-engineered rubber. Hainan ball bearing, Hao-quality conquer the world, damping ball bearings are Hengshui HaoTong Engineering Rubber Co., Ltd. (www.htgcxj.com) 2014 has been newly upgraded launched using ball bearings Problems, design, design units currently found in some of laminated rubber bearings and bridge and culvert design specifications, industry standard design requirements do not match. Such as flat-size design is very large, but the thickness of thin bearing, spherical bearing checking the projects carried out in accordance with the relevant provisions of the bridge specifications and industry standards, and its compression, rotation performance can not meet the requirements, the more shear deformation small, even as the use of fixed bearing, ball bearing must also meet the requirements before end of the beam angle. Such a ball bearing, in the course of Void and prone to accelerated aging, causing the ball bearing damage early, so, JT / T 4-2004 value specified in the measured bearing angle, rubber bearing reinforced concrete not less than 1/300 of a two-way bridge movable ball bearing, steel bridge greater than or equal to 1/500, and at the time of factory production and production licenses issued, as the content of the test must be carried out. In addition, designers in the selection of laminated rubber bearings, the ball bearing and the bearing capacity of the bridge actually supporting reaction force should be consistent with the general range of about 10 percent of excellence, you can meet your requirements, not the choice of bearing bearer The larger force than necessary bearing capacity of more secure, ball bearings, especially ball bearings, the bridge should be as close to the actual carrying capacity when selecting ball bearings, because PTFE sheet and endlessly when dry plate friction with positive pressure decreases. Almost does not allow this type of ball bearing angle or simply does not allow any corner, paying particular attention to the use of seismic ball bearings, and can use different forms of permanent stress value based on the relationship between common form, carrying capacity and plate width . Such rubber bearings used in a span of more than 6m structure, and can use a certain angle requirements, rubber bearings made of polystyrene foam between the two lateral panels resistance to embed a 5mm thick elastic core blocks, pellets The main role is as follows: (1) a load in the seat center. (2) ball bearings to absorb rotational deformation damping ball bearings to prevent strain transfer to the lower edge of the structure, which can achieve to avoid damage to the cracks and corners. (3) The ball bearing can absorb such a displacement of 2.5mm ball bearings are generally two kinds A and B form, in which A is a slide-type structure, and the structure of the two B-type slider, the upper surface lined with polystyrene foam, such a ball bearing structure and parameters. Bearing a fixed or sliding point of contact when the contact point bearing, ball bearing can absorb the displacement of the contact point and to each of the displacement and rotation, to ensure uniform distribution of the load, such a ball bearing is often used residential and process buildings, parking and appearance of complex structures.
