Rolling steel bearing manufacture

Rolling bearings are divided into several types
The following are common ones
If there are other structures, they can be customized according to the drawing

Design of rolling bearing: rolling bearing is a common bearing form for long-span bridges and truss corridor bridges
It is usually connected by two small-diameter roller shafts in parallel
The number of roller shafts depends on the reaction force of the support
According to the line contact stress and the required diameter of a single roller shaft, an arc bearing is added on the top of a group of roller shafts so that the beam end can rotate freely, The stiffness of the support bottom under the roller shaft is based on the flatness of the support bottom plate

And it can resist well when the earthquake comes
During the earthquake, rigid seismic measures and flexible vibration reduction measures act at the same time to resist the huge earthquake input energy, which can not only ensure the reasonable relative displacement of the upper and lower structures of the bridge, reduce the amplification factor of seismic force, but also maintain the unity of the structure
The bearing can resist earthquakes of 8-11 degrees, and has good seismic and vibration reduction effect on engineering structures in high intensity earthquake areas, especially in direct earthquake areas
Performance characteristics of rolling bearing
Rolling bearing is a targeted rolling bearing, which can be designed according to the needs of users
It has the following advantages:
Maintenance free & mdash& mdash; Due to the inherent characteristics of the shaft sleeve material, there is no need to add oil during operation and maintenance for life;
High bearing capacity & mdash& mdash; Because it is mi contact, its bearing capacity is stronger than that of tapered small roller bearing;
Low friction coefficient & mdash& mdash; Because there is graphite in the material of the shaft sleeve, it has the function of self lubrication, and its friction coefficient is small;
 
High temperature resistance & mdash& mdash; Because its lubrication is not lubricating oil, the higher the inherent characteristic temperature of the material, the smaller the friction coefficient Our company produces rolling bearings
The function of rolling bearing is to release horizontal constraints, which is mainly used to release the horizontal thrust of the structure, including the thrust generated by temperature stress and structural arch effect
