dual-spherical shock isolation bearings
First, the introduction of products
Double spherical ball bearing isolation is composed of top plate, bottom plate, double spherical body, concave spherical liner, wear plate, flat wear plate, polyurethane damping block, shear ring and other components. It has large displacement, large angle characteristics, bearings from ambient temperature limit, wide application range.
Two, product features
1, the upper and lower seat plate working face is concave spherical surface, and the hard chromium plating technology is adopted, which has high wear resistance and low friction coefficient, and improves the performance of the support;
2) the combined use of the double spherical body and the wear-resistant plate of the spherical surface makes it have good performance of rotating friction;
3) wear resistant plate using modified ultra-high molecular weight polyethylene, to meet the needs of the large carrying capacity also has a good wear resistance;
4) can be designed according to the requirements of large displacement, large angle (0.04rad), to meet the needs of large displacement, large angle bridge, the bearing is not limited by the use of environmental temperature, wide range of application;
5) polyurethane damping block to make the bearings have a good isolation performance;
6. The application of the sliding friction pair with the support of the double spherical surface, the vertical lifting of the horizontal movement of the bearing in the earthquake condition, the kinetic energy is converted to potential energy, to consume the earthquake energy.
7) after the earthquake bearing under the effect of gravity, have a good ability to reset, bearing and beam body from damage, bearing no need to replace.
Three, product application
Double spherical ball bearing isolation technology condition of People's Republic of China strict implementation of national standard GB/T 17955-2009< ball bearing ", also referring to the European Committee for Standardization Technical Committee CEN/TC 167 August 1993 promulgated draft structure support standard seventh" ball type and column type teflon bearings "and second" slide ", the British standard BS 5400< steel bridge, concrete bridge and bridge combined with the provisions of article ninth >" bridge bearings ".
Our company through the independent research and development of production of SQZ (9000 ~ 57500) KN double spherical base isolation bearings. The successful application of Hong Kong Macao Bridge, Xinjin River Bridge and other domestic large and medium-sized bridge projects.
