Abstract

The utility model relates to a slope-shaped ring pot type rubber bearing, comprising a top cover, bearing rubber, a slope-shaped ring bottom pot, a rubber sealing ring and a copper sealing ring, wherein a lower convex cylinder on the top cover is embedded into the slope-shaped ring bottom pot; the bearing rubber is arranged in a pot cavity of the slope-shaped ring bottom pot; a pot ring structure of the slope-shaped ring bottom pot is thin at the upper part and thick at the lower part; and the outer side surface of the pot ring of the bottom pot is designed into a conical surface, and the inner side surface thereof is designed into a cylindrical surface. Since the slope-shaped ring pot type rubber bearing adopts the structure and a new forming technique, the cylindrical surface is from machining, simultaneously, the use amount of cast steel for the bottom pot is saved, and the workload of machining is also reduced.

Description

Domatic ring pot rubber bearing

Technical field

The utility model relates to a kind of ring pot rubber bearing, refers in particular to a kind of ring pot rubber bearing that is applicable to bridge and viaduct beam-ends.

Background technology

Basin basin ring all is an equal thickness at the bottom of all pot rubber bearings of bridge use at present, carries out machine behind casting, and machining allowance generally needs 6～8mm.The basin rim bearing is being subjected to be installed on the effect of the radial level pressure that the rubber in the basin produces under the vertical load effect, pressure increases from top to bottom gradually.At the bottom of the pot rubber bearing basin basin ring all be the equal thickness structure as shown in Figure 1.

Therefore, the basin ring adopts equal thickness design shortcoming to be: (1) does not give full play to the supporting capacity of steel; (2) the basin ring outside also needs the machining allowance of 6～8mm, has not only increased the cast steel consumption, has also increased the machine workload, has caused the waste of resource.

The utility model content

The utility model has designed a kind of domatic ring pot rubber bearing, the technical problem of its solution: (1) tradition ring pot rubber bearing fails to give full play to the supporting capacity of steel; (2) tradition ring pot rubber bearing needs more steel and more machine workload.

In order to solve the technical problem of above-mentioned existence, the utility model has adopted following scheme:

A kind of domatic ring pot rubber bearing comprises basin at the bottom of top cover, pressure-bearing rubber, the domatic ring, rubber seal and copper sealing ring; Be arranged in following dome cylinder on the top cover and embed basin at the bottom of the domatic ring, pressure-bearing rubber is installed at the bottom of the domatic ring in the basin pelvic cavity.The basin ring structure of basin is up-thin-low-thick at the bottom of the domatic ring.

The lateral surface of basin is designed to taper seat at the bottom of the domatic ring, and medial surface is designed to the face of cylinder.

Copper sealing ring is placed on the described pressure-bearing rubber end face outer rim; Copper sealing ring closely contacts with the inboard face of cylinder of basin at the bottom of the domatic ring; Top cover is placed in pressure-bearing rubber and above the copper sealing ring, top cover is that face contacts with pressure-bearing rubber and copper sealing ring.

Copper sealing ring is a sheet opening annulus.

Be inlaid with rubber seal in the annular groove of basin basin top surface of ring at the bottom of the domatic ring, the end face of rubber seal contacts with top cover edge of a wing soffit.

This domatic ring pot rubber bearing compared with prior art has following beneficial effect:

(1) basin basin ring was under the effect of pressure-bearing rubber lateral pressure at the bottom of the utility model utilized the domatic ring, and the characteristics that basin ring stress is up-small and down-big are designed to up-thin-low-thick structure with end basin basin ring, meet engineering mechanics more.

(2) the utility model is designed to up-thin-low-thick structure with end basin basin ring, and adopts new casting technique, and basin ring outside slope does not need to carry out machine, and this has not only reduced end basin cast steel consumption, has also reduced the amount of machining and the processing cost of end basin simultaneously.

The specific embodiment

Below in conjunction with Fig. 2-5, the utility model specific embodiment is described in further detail.

Shown in Fig. 2-5, a kind of domatic ring pot rubber bearing, it by top cover 1, pressure-bearing rubber 2, domatic ring at the bottom of basin 3, rubber seal 4 and copper sealing ring 5 constitute.Top cover 1 upper surface is a square planar, and four jiaos have bolt hole, and protruding cylinder is down arranged below the top cover, and the cylinder bottom surface is the plane; Pressure-bearing rubber 2 is cylinder, and upper and lower surface is the plane; Basin 3 basin tops surface of ring are the plane that has annular groove at the bottom of the domatic ring, and the pelvic cavity bottom surface is the plane, and basin ring medial surface is the face of cylinder, and lateral surface is a taper seat, are square planar at the bottom of the basin, and four jiaos have bolt hole; Copper sealing ring 5 is a sheet opening annulus.

Pressure-bearing rubber 2 is installed at the bottom of the domatic ring in basin 3 pelvic cavity, and its side contacts with the 3 inboard faces of cylinder of basin at the bottom of the domatic ring; In pressure-bearing rubber 2 end face outer rims, lay copper sealing ring 5, copper sealing ring 5 closely contacts with the 3 inboard faces of cylinder of basin at the bottom of the domatic ring; Top cover 1 is placed in pressure-bearing rubber 2 and above the copper sealing ring 5, with pressure-bearing rubber 2 and copper sealing ring 5 for face contacts, there is very little gap on the inboard face of cylinder of basin 3 basin rings at the bottom of the following dome cylinder face of cylinder of top cover 1 and the domatic ring; Be inlaid with rubber seal 4 in the annular groove of basin 3 basin tops surface of ring at the bottom of the domatic ring, the end face of rubber seal 4 contacts with top cover 1 edge of a wing soffit.

Operating principle of the present utility model is as follows: the vertical load that acts on domatic ring pot rubber bearing is passed to pressure-bearing rubber 2 by top cover 1, passes to basin 3 at the bottom of the domatic ring by pressure-bearing rubber 2, reaches the basis by basin 3 at the bottom of the domatic ring again.The horizontal loading that acts on domatic ring pot rubber bearing by top cover 1 and domatic ring at the bottom of shearing resistance between the basin 3 reach basin 3 at the bottom of the domatic ring, frictional force and the connecting bolt by basin at the bottom of the domatic ring 3 and basis reaches the basis again.2 rotational deformation of coordinating to be installed on the works on the utility model by its uneven compressive strain of pressure-bearing rubber.
