Pot rubber bearing

1, pot rubber bearing, structure and performance:

Pot rubber bearing is used by the elastic rubber piece inside the pelvic cavity, semi-closed steel under three to stress is the nature of the fluid characteristics, to achieve the rotation of the upper bridge, at the same time rely on the middle plate of the F4 plate and top plate of stainless steel plate for low coefficient of friction between the horizontal displacement of the upper structure, make the bearing on the shear bear completely by the rubber, no longer and indirect effect on the bottom of the steel on the slip between basin and F4 plate and stainless steel. From the perspective of the data of experiment, the rubber is in a state of three to the constraints of the compressive modulus of elasticity of 50000 kg/cm2, than no lateral restraint of compressive elastic modulus increases nearly 20 times, thus bearing capacity greatly improved, to solve the limitation of plate rubber bearing capacity, can meet the needs of large bearing reaction force, large horizontal displacement and Angle of requirements.

Bearing performance:

(1), design of the vertical bearing capacity of this series of bearing capacity of bearing design level 33 points, namely, 0.4, 0.5, 0.6, 0. 8, 1, 1.5, 2, 2, 3, 5, 3.5, 4, 5, 6, 7, 8, 9, 10, 15, 17.5, 12.5, 20, 22, 5, 25, 27.5, 30, 40, 45, 35, 37.5, 32.5, 50, 55 and 60 mn.

(2), horizontal bearing capacity: fixed support level in each direction and a one-way bearing the sliding direction of horizontal bearing capacity are not less than 10% of the vertical bearing capacity of the bearing. Suspension type fixed support and suspension type one-way activities support the sliding direction of horizontal bearing capacity are not less than 20% of the vertical bearing capacity of the bearing.

(3), the coefficient of friction: after 5201 silicon grease lubrication, normal temperature type activities bearing friction coefficient is not more than 0.030; After add 5201 silicon grease lubrication, cold type activities bearing friction coefficient is greater than 0.060.

(4), support to: support allows the Angle of not less than o. O2rad.

(5) seismic bearing displacement and displacement one-way activity, transverse and 3 mm, longitudinal displacement are shown in table 1.
