Abstract
The present invention relates to building field and is a kind of two-sided position limiting friction slipper with great sliding displacement, less HF vibration and adjustable friction coefficient. The slipper includes upper friction sliding part and lower friction sliding part and features that its upper friction sliding part and lower friction sliding part have opposite raised edges and flat middle parts with friction sliding part in between. There are rubber rings outside the upper firction sliding part and lower friction sliding part and round the middle friction sliding part.
Description
The invention belongs to the sliding isolated bearing of building field aspect, but particularly a kind of two-side limit friction slipper of limit levels slippage, and it can reduce the generation of dither.
Known slip support abutment has: adjustable friction slipper as shown in Figure 1, the direct slide friction slipper as shown in Figure 2, vibration controlled frictional slip support abutment as shown in Figure 3, these slip support abutments have advantage, also exist following shortcoming and problem:
1, satisfying under the condition of maximum displacement, the area of each sliding component of bearing is big, has therefore improved the requirement to external object.
2, the direct slide friction slipper, adjustable friction slipper can not the limit levels displacement.
The objective of the invention is: a kind of two-side limit friction slipper is provided, it with the constant condition of external object contact area under, the displacement of slippage is big, but the limit levels displacement can reduce the generation of dither, protects displacement surface for a long time.
Technical scheme of the present invention is: design a kind of two-side limit friction slipper, it comprises frictional slip spare, following frictional slip spare, it is characterized in that: go up frictional slip spare and simultaneously be that outstanding middle part is straight frictional slip face around straight, the one side, following frictional slip spare simultaneously is that outstanding middle part is straight frictional slip face around straight, the one side, between last frictional slip spare and the following frictional slip spare is the intermediate friction sliding component, and the intermediate friction sliding component is dull and stereotyped.
The described frictional slip spare of going up, one side are that outstanding middle part is straight circular frictional slip face around straight, the one side.
Described down frictional slip spare, one side are that outstanding middle part was straight circular frictional slip face around straight, one side was.
Described intermediate friction sliding component, the frictional slip face is straight circular slab up and down.
The present invention and known technology contrast are as follows:
1, when the area that contacts with external object was constant, the displacement of slippage was big.
Because known technology slip support abutment as depicted in figs. 1 and 2, its slippage equals the slippage of frictional slip spare, the slippage of slip support abutment shown in Figure 3 equals the slippage of intermediate friction sliding component, and the both surface friction slip support abutment of the present invention's design, displacement is to go up frictional slip spare displacement and following frictional slip spare displacement sum.This be because last frictional slip spare with contact above the intermediate friction sliding component, last frictional slip spare is with respect to the displacement of intermediate friction sliding component, following frictional slip spare contacts with the intermediate friction sliding component, following frictional slip spare is with respect to the displacement of intermediate friction sliding component.Make frictional slip spare, down frictional slip spare is all with respect to the displacement of intermediate friction sliding component, so produced displacement big when having only last frictional slip spare not have the intermediate friction sliding component with following frictional slip spare.But and in the horizontal movement process limiting displacement amount; In the horizontal movement process, avoid simultaneously the generation of dither.
Because it is outstanding around last frictional slip spare and two opposite faces of following frictional slip spare; but therefore pass through the horizontal displacement of intermediate friction sliding component limit slip; the rubber ring of frictional slip spare and following frictional slip spare in the connection is equipped with in outstanding outside around the upper and lower frictional slip spare; and after intermediate friction sliding component side surface is with rubber ring; can avoid in slipping, producing dither, protect the frictional slip face for a long time.
3, because friction factor is relevant with the size of pressure, pressure increases friction factor and reduces, and utilizes the slippage contact area of adjusting the intermediate friction sliding component, reaches the effect of adjusting friction factor.
4, because frictional slip spare up and down, all be one side for outstanding middle part around straight, the one side be straight circular frictional slip face.So the slippage contact surface is big, the slippage of all directions is identical, and slide surface is not adjusted about not needing, and can be inverted, and production technology is simple, easily standardization, and cost of production is low.
5, intermediate friction sliding component, its face of frictional slip up and down can be straight circular slab, the impact wreckage in the time of can reducing contact, all directions slippage is big.
The present invention will be further described below in conjunction with the embodiment accompanying drawing.
Fig. 1 is the adjustable friction slipper of known technology.
Fig. 2 is the direct slide friction slipper of known technology.
Fig. 3 is the vibration controlled frictional slip support abutment of known technology.
Fig. 4 is the section of structure of embodiment 1 two-side limit friction slipper.
Fig. 5 is the slip state schematic diagram of embodiment 1 two-side limit friction slipper.
Fig. 6 is the inversion figure of embodiment 1 two-side limit friction slipper.
Fig. 7 is the upward view of frictional slip spare on the embodiment 1.
Fig. 8 is the vertical view of 1 time frictional slip spare of embodiment.
Fig. 9 is embodiment 1 an intermediate friction sliding component structural representation.
Among the figure: 1, go up frictional slip spare 2, following frictional slip spare; 3, intermediate friction sliding component; 4, rubber ring; 5, rubber ring.
As shown in the figure, be with rubber ring 4 at intermediate friction sliding component 3 side surfaces, it can reduce edge effect and reduce the generation of creeping, and avoids dither.Last frictional slip spare 1 contacts with intermediate friction sliding component 3 upper surfaces, and following frictional slip spare 2 contacts with intermediate friction sliding component 3 soffits.Be connected with rubber ring 5 on the outer concave edge of giving prominence to around last frictional slip spare 1 and the following frictional slip spare 2, be used to protect the frictional slip face, after the slippage of both surface friction slip support abutment, rubber ring 5 is destroyed.
The both surface friction slip support abutment sliding displacement amount of the present invention's design is big, adjust the size and the size of following frictional slip spare or the size of intermediate friction sliding component that go up frictional slip spare as required, after the manufacturing materials processing or selecting suitable material for use, can reduce edge effect and reduce the generation of creeping.Because the both surface friction slip support abutment is made simple, the product quality assurance that is easy to get helps seriation suitability for industrialized production in batch, helps applying.On the frictional slip face, also can require to increase the frictional slip rete, to adjust friction factor according to difference.
