Bearing capacity of bridge bearing

The standard series, fixed support in all directions and unidirectional movable support non slip direction of the horizontal bearing capacity is not less than the level of 10%. bearing vertical seismic bearing capacity of the bearing capacity of not less than 20%. bearing vertical bearing capacity of the bearing of the rotation angle is not less than 0.02rad. 5201 grease lubrication, friction bearing design activities at room temperature the minimum resistance coefficient 0.03.

Add 5201 grease lubrication, cold type movable bearing design minimum friction coefficient 0.06.

What is the difference between plate rubber bearing and PTFE sliding plate rubber bearings?

PTFE sliding plate rubber bearings and rubber bearing are laminated rubber bearing, the distinction between simple it can be said that the PTFE sliding plate rubber bearings for plate rubber bearing, it can use PTFE plate and stainless steel plate to grease sliding resistance minimum.

Plate type rubber bearings (in fact, should be called ordinary plate type rubber bearing) can be seen as a fixed plate type of rubber bearings, can not be used as a sliding bearing.

The small span simply supported beam, longitudinal displacement due to small, then do not need PTFE sliding plate rubber bearings, normal rubber bearing shear displacement can meet the requirements of large span beam; it needs two kinds of bearing with the use.
