Using ball bearings should be noted that the problem of 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 can not meet the performance requirements of the seismic GQZ type ball-shaped steel support Block, shear deformation even smaller, even as the use of fixed bearing, spherical bearings must also meet 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 stipulated in the corner of the measured value of the fixed bearing steel ball bearing type GQZ , rubber bearing reinforced concrete bridge greater than or equal to 1/300 of steel bridges greater than or equal to 1/500, and production at the factory 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 the choice of ball bearings, the bridge should be as close to the actual capacity, because PTFE sheet and endless dry plate friction when positive pressure decreases with increasing Great. If the ball bearing gel content is mainly the incorporation of recycled rubber, these indicators it is difficult to pass, so this is one of the elements to ensure product quality to shut trace, with the increasingly fierce market competition, we Like other products damping GQZ steel ball bearing type, the same price war, when the ball bearing long-term goal of the project gone, some manufacturers also used to reduce the amount of plastic containing or by other means to reduce the sales price of rubber bearings, Meanwhile, only the appearance can not see the merits of products, and engineering contractors are often the lowest priced bid again, forcing some manufacturers have come up with various ways to reduce their costs, for the marketplace. In the 1900s, early 1980s, when the ball bearing leverage our marketing, to buy a 0.05 rubber bearings, spherical bearings to buy a 0.08, but when the price of rubber, neoprene more expensive, and natural rubber To lower. In this price due to rising raw material prices and labor costs, make some formal manufacturers in the production of laminated rubber bearings in trouble, in fact, the entire bridge engineering, ball bearings accounted for only 2% of the total amount of bridge ~ 3%, ball bearing procurement unit which pushes prices too low, ball bearing virtually forcing manufacturers to reduce costs. This will greatly reduce bearing life. Reduce the amount of plastic containing substantially equal to the required safety standards to reduce the cost of the degree.
