Combined ball bearing

Abstract

The invention discloses a combined ball shock insulation support. The combined ball shock insulation support comprises an upper connecting plate, a limiting plate, a positioning plate, a ball cover plate, balls, a ball distance limiting plate, a base plate, reset rubber, a limiting positioning column, a reset positioning bolt, a positioning ball, a positioning ball support, a positioning spring, a movable lever, a movable lever support and the like. An earthquake time fixed layer is formed by the upper connecting plate, the positioning plate and the ball cover plate, an integral is formed by the earthquake time fixed layer and a building, an earthquake time moving layer is formed by the base plate, the movable lever support and the movable lever, an integral is formed by the earthquake time moving layer and the ground, a rolling shock insulation layer is formed by the balls and the ball distance limiting plate, the shock insulation capacity is high, the energy produced by the earthquake can be isolated by the rolling shock insulation layer and is not transmitted to the building, the balls can be isolated through the ball distance limiting plate, and damage of the balls due to friction and extrusion is avoided. The movable lever is pressed on the limiting plate, the tension resisting capacity is greatly improved, and the overall bearing intensity is large. A pencil lead is added into the reset rubber, and therefore the reset performance of the reset rubber is greatly improved.

Description

technical field [0001] The invention belongs to the technical field of vibration isolation and shock absorption of building structures, in particular to a combined ball vibration isolation bearing. Background technique [0002] Earthquake is a natural disaster that has been accompanied by the development of human history. In the early 20th century, humans adopted seismic design methods to resist earthquakes. Earthquake resistance is to resist the earthquake force by thickening the steel bars, increasing the strength of the main body of the building such as beams and columns, but the earthquake force is so strong that it often causes the building to break and collapse from the root as a whole. Practice has shown that the effect of this anti-seismic method is not obvious. Because the root of the building is the first to be damaged by an earthquake in an earthquake-resistant building, people have been inspired, and the base isolation design method was produced in the late 20t...

AI Technical Summary

Problems solved by technology

Although the ball vibration isolation effect is good, its own shortcomings limit its promotion in practical applications. The disadvantages are: poor positioning ability, large displacement, no reset function, no tensile resistance, high friction between balls and easy to be squeezed Broken etc.
