Vertical roller bearings
First, the introduction of products
The roller bearing is composed of a vertical top plate, bottom plate, roller base, rubber board, skateboard, Bush, shaft, rocker, upper and lower plate, fixed plate and other components. It has large displacement, large angle, and the tensile properties of the vertical function, suitable for cross the river, cross the Canyon, cross sea bridge project.
Two, product features
1 the rubber plate in the base of the base is in a three phase constraint state, the energy absorption of the rubber, the energy dissipation function is fully played, and has the advantages of large bearing capacity, shock absorption, and obvious isolation effect;
2) the combination of slide and the lower seat board is used, which has good performance in vertical tension, to overcome the negative moment of beam end portion of the stress occurs, the mechanical model of force in accordance with the actual beam under the;
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 the use of large displacement (800mm), large angle (0.04rad), to meet the needs of large displacement, large angle bridge;
5) bearings using cylindrical rolling friction force transmission line structure, model structure, sliding in the main direction of displacement and flexible, can meet the needs of large displacement. At the same time can be load in different directions of beam uniformly vertical transfer to the pier, the level of force is converted into a horizontal scroll displacement, reduces the size of the force bearing level is. The ideal mechanical stress model.
Three, product application
Series of vertical roller ball bearing to strictly enforce the technical conditions of People's Republic of China 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 ". The bridge standard development component products and related industry standards.
Our company through the independent research and development of SZ4000/1250KN roller shaft vertical bearing. Related specifications of the ball type bearing has been successfully applied to the river bridge and other large and medium-sized domestic bridge engineering.
