Detailed description of the invention
Below in conjunction with the accompanying drawings the concrete structure of multi-stage friction provided by the utility model pendulum vibration absorption and isolation support is done into one
Step explanation.
As it is shown in figure 1, multi-stage friction provided by the utility model pendulum vibration absorption and isolation support includes upper base plate 1, middle liner plate
2, lower seat board 3, is provided with spherical crown plate 4, is provided with between middle liner plate 2 and lower seat board 3 between upper base plate 1 and middle liner plate 2
Lower spherical crown plate 5, between upper base plate 1 and upper spherical crown plate 4, between upper spherical crown plate 4 and middle liner plate 2, middle liner plate 2 and lower spherical crown plate
Between 5, lower spherical crown plate 5 contact for cambered surface between lower seat board 3, the bottom of upper base plate 1 is provided with and matches with upper spherical crown plate 4
First draw ring 6, the bottom of upper spherical crown plate 4 is provided with the second draw ring 7 matched with middle liner plate 2, and the top of lower spherical crown plate 5 sets
Being equipped with the 3rd draw ring 8 matched with middle liner plate 2, the top of lower seat board 3 is provided with the 4th matched with lower spherical crown plate 5 and draws
Ring 9.
As in figure 2 it is shown, horizontal, second draw ring 7 of the first draw ring 6 and the second draw ring 7 and middle liner plate 2 horizontal, the 3rd
Horizontal, the 3rd draw ring 8 of draw ring 8 and middle liner plate 2 and the 4th draw ring 9 be laterally respectively arranged with fixed plate 10.
Multi-stage friction provided by the utility model pendulum vibration absorption and isolation support, is provided with between upper base plate 1 and middle liner plate 2
Spherical crown plate 4, is provided with lower spherical crown plate 5 between middle liner plate 2 and lower seat board 3, between upper base plate 1 and upper spherical crown plate 4, upper spherical crown plate
Between 4 with middle liner plate 2, between middle liner plate 2 and lower spherical crown plate 5, lower spherical crown plate 5 contact for cambered surface between lower seat board 3, whole
Individual bearing constitutes upper pendulum, interior pendulum and the bottom.When little shake occurs, as it is shown on figure 3, the second draw ring 7 of upper spherical crown plate 4 pulls centre
Liner plate 2 slides on lower spherical crown plate 5, swings and make in middle liner plate 2, until middle liner plate 2 contacts with the 3rd draw ring 8.Central shake
