Abstract
The present invention relates to an anti-shock spherical steel supporting seat mainly composed of an upper cover, a middle core, a base and a sealing ring and characterized in that a convex rabbet A and a concave rabbet B are arranged at the upper part of the base 4 along a flanged edge; the concave rabbet B is arranged in the corresponding position of the upper cover 1 and the convex rabbet A of the base 4. The upper cover is engaged with the concave rabbet and the convex rabbet of the base, which causes the base to be locked with the upper cover; while in strong shock, the present invention can not result in beam fall or frame fall, which avoids the generation of serious consequence. Two annular ash storage slots C are arranged on the upper end surface and the lower end surface of the sealing ring 2, which reduces the compression cross section of the sealing ring, lowers compressive rigidity, increases dustproof rings, enhances sealing effect, has little possibility of dust enter, lowers abrasion and extends the service life of the supporting seat.
Description
The present invention relates to a kind of ball shaped steel bearing, be applicable to the bearing of railway bridge, road bridge, kind large space structure.
Existing ball shaped steel bearing such as hair are reined in the ball shaped steel bearing that (Maurer) company produces, and it is mainly placed by the overlap joint of the sealing ring between loam cake, SMIS, base and loam cake and the base and forms.Therefore, it can only bear pressure, so be scattered easily when earthquake, causes beam or the frame that falls, and produces serious earthquake.Because the sealing ring section is a rectangular cross section, when bearing rotated, excessive because of rigidity, decrement was little, influenced bearing and freely rotated, and caused sealing effectiveness poor in addition.
The present invention constitutes like this: on base top, radially be provided with protruding tongue and groove and recessed tongue and groove along flange; The protruding tongue and groove opposite position of loam cake and base is established recessed tongue and groove.Sealing ring is provided with the storage ash-pit, reduces compressing area, reduces pressurized rigidity.
The beneficial effect that the present invention is compared with prior art had is: because the junction of base and loam cake is provided with protruding tongue and groove and recessed tongue and groove, during use, base and loam cake are pinned, during macroseism, can not cause the beam or the frame that falls, avoid producing serious consequence.Because sealing ring is provided with the storage ash-pit, reduced sealing ring pressurized cross section in addition, reduced compressional stiffness, increased the dustproof number of turns, improved sealing effectiveness, dust is difficult for entering, and has reduced abrasion, increases bearing application life.

The profile of Fig. 6 sealing ring
With the accompanying drawing is that the invention will be further described for embodiment:
Shock-proof ball shaped steel bearing (Fig. 1) mainly is made up of loam cake 1, sealing ring 2, SMIS 3, base 4.
On the top of base 4, along protruding tongue and groove A of radially being provided with of flange and recessed tongue and groove B (Fig. 4,5); Along loam cake 1 bottom flange radially, establish recessed tongue and groove B and protruding tongue and groove A (Fig. 2,3) with the protruding tongue and groove A and the recessed tongue and groove B opposite position of base 4.α is recessed tongue and groove angle, and β is the angle of protruding tongue and groove; α is slightly larger than β.Because the setting of protruding tongue and groove and recessed tongue and groove, the ball shaped steel bearing after the assembling can be pinned.When guaranteeing macroseism, top rack or bridge beam body are unlikely to come off.Simultaneously, all right universal rotation is rotated flexibly.
On upper and lower two end faces of sealing ring 2, establish two annular storage ash-pit C (Fig. 6), constitute three layers of disjunctor rubber seal, increased sealing effectiveness greatly; Simultaneously, reduced the width of individual pen, the rotary resistance of bearing is reduced greatly, rotated more flexible.
During assembling, SMIS 3 and sealing ring 2 place on the base 4, and the recessed tongue and groove B with on the protruding tongue and groove A aligning base 4 of loam cake detains, and rotation (alpha+beta)/2 angle is about to loam cake 1 and base 4 pins, and plays the anti-falling stop beam action of antidetonation.
Claims (2)
1. shock-proof ball shaped steel bearing, it mainly is made up of loam cake, SMIS, base and sealing ring, it is characterized in that: the top in base (4) radially is provided with protruding tongue and groove (A) and recessed tongue and groove (B) along flange; Loam cake (1) is established recessed tongue and groove (B) with protruding tongue and groove (A) opposite position of bottom (4).
