Abstract
The utility model relates to a bridge bearing long-acting lubricating friction pair, which comprises a spherical cap lining plate (1), a middle steel lining plate (2) under the spherical cap lining plate (1), a four-fluorine plane slide plate (3) positioned on the upper plane of the spherical cap lining plate (1) and a four-fluorine spherical slide plate (4) positioned on the upper spherical surface of the middle steel lining plate (2). The utility model is characterized in that the four-fluorine plane slide plate (3) and the four-fluorine spherical slide plate (4) are provided with a plurality of fat storing dents (5) and oil grooves (7, 8), and the oil grooves on the four-fluorine plane slide plate (3) and the four-fluorine spherical slide plate (4) are communicated and are connected with an oil injection groove (6) of which the outer end opens. The utility model can replenish lubricant in time to achieve long, uniform and high-quality lubricating effect so as to ensure that the supporting seat can slip and rotate flexibly.
Description
Technical field:
The utility model relates to bridge pad, especially a kind of long-acting lubrication friction pair of bridge pad.
Background technology:
Bridge pad is the critical component in the bridge construction.On the one hand, it will bear the load of bridge superstructure, with the seismic load of bridge substructure etc. by passing to superstructure after the bearing decay.On the other hand, it will adapt to bridge construction distortion needs, comprises the sedimentation etc. of linear displacement, angular deflection and the substructure of beam body.In order to guarantee that girder construction exempts from displacement and is obstructed and destroys, the general requirements girder construction is capable of expansion and contraction, rotates flexibly.For this reason, except adopting antifriction material (but cost is than higher), it is efficient ways that the frictional rotation face is adopted the lubricated of necessity.All previous evidence can reduce frictional force more than 50% by adopting lubricant method.
At present, the lubricating system of bridge pad is lubricated for stainless steel-polytetrafluoroethylene (PTFE) friction pair being carried out silicone grease, and this is a kind of mode that generally adopts.Itself has stable chemical property silicone grease, and acid and alkali-resistance salt performance is all relatively good, and the slide surface material is not had corrosiveness.At present, the general method that adopts disposable filling in the structure design, there is certain shortcoming in this method:
One, at present, the hermetically-sealed construction of slide surface is not set in the standard, can't guarantees in the bearing
Sliding agent does not run off, and general sliding agent only works in the friction period of adjustment;
Two, for specific adjustment structure, be in course of adjustment and can cause the minimizing of amounts of lubrication,
Can't guarantee permanent, high-quality lubricant effect.
Abroad, what Switzerland adopted is the tiny lubricated piece splicing construction of polylith, but this structure must adopt total control techniques could guarantee the center to center distance of height and the degree of depth and each slide block of each fritter.Its process technology level requires very high, at present, domesticly also do not reach this level of processing, and the processing cost of this structure is too high.In view of at present domestic level of processing with consider its cost of production.This structure can't extensive use and universal.
Summary of the invention
The utility model is intended at existing bridge pad friction pair plane of rotation, slide surface bleeding of lubricant phenomenon, and stable for guaranteeing sliding agent dosage, lubrication is played in long-acting use better, provides a kind of bridge pad long-acting lubrication friction pair.
For solving the problems of the technologies described above, the technical scheme that the utility model adopted is as follows:
The long-acting lubrication friction pair of a kind of bridge pad, comprise the spherical crown liner plate, the middle steel liner plate of spherical crown liner plate bottom, be positioned at plane on the spherical crown liner plate plane tetrafluoro slide plate, be positioned in the middle of the sphere tetrafluoro slide plate of sphere on the steel liner plate, it is characterized in that: plane tetrafluoro slide plate and sphere tetrafluoro slide plate are provided with some depot fat pittings and oil groove, oil groove on plane tetrafluoro slide plate and the sphere tetrafluoro slide plate communicates, and links to each other with the oiling groove of outer end opening.
The utility model oil groove comprises cannelure and radial slot, and described cannelure and radial slot intersect, and the oil groove on plane tetrafluoro slide plate and the sphere tetrafluoro slide plate links to each other through vertical centre gangway.
The utility model oiling groove is communicated with cannelure.
Steel liner plate in the middle of the utility model oiling groove is positioned at, outer end opening.
The beneficial effects of the utility model show:
One, processing is easy, cost is low;
Two, increase the loaded area of tetrafluoro slide plate, both increased its bearing capacity, saved material again
Material;
Three, supplemental lubrication agent in time, reaching permanent, even, high-quality lubricant effect,
Thereby guarantee the bearing slippage and rotate flexible;
Four, high lubricating effect, easy to operate.
Description of drawings Fig. 1, Fig. 2 have represented the process that oiling and grease flow to for the utility model cross-sectional view Fig. 3, Fig. 4 for the utility model top plan view structural representation Fig. 4 width of cloth figure.
The specific embodiment
The long-acting lubrication friction pair of a kind of bridge pad comprises spherical crown liner plate 1, the middle steel liner plate 2 of spherical crown liner plate 1 bottom, be positioned at plane on the spherical crown liner plate 1 plane tetrafluoro slide plate 3, be positioned in the middle of the sphere tetrafluoro slide plate 4 of sphere on the steel liner plate 2.Plane tetrafluoro slide plate 3 and sphere tetrafluoro slide plate 4 are provided with some depot fat pittings 5 and oil groove, and the oil groove on plane tetrafluoro slide plate 3 and the sphere tetrafluoro slide plate 4 communicates, and link to each other with the oiling groove 6 of outer end opening.Oil groove comprises cannelure 7 and radial slot 8,
Present embodiment adopts the mode in the fan-shaped slide plate split embedding spherical crown liner plate, and cannelure is divided into a circle and the outer ring of circle with slide plate, and 6 radial slots 8 are divided into 6 segments with slide plate 3,4.Described cannelure 7 intersects with radial slot 8, and the oil groove 7,8 on plane tetrafluoro slide plate 3 and the sphere tetrafluoro slide plate 4 links to each other through vertical centre gangway 9.
Operating principle of the present utility model is:
The route that sliding agent is flowed through is: pouring orifice on the middle steel liner plate injects oil groove → inflow spherical crown liner plate oilhole passage of reserving between the sliding agent → oiling groove of flowing through → inflow sphere tetrafluoro slide plate → flow at last oil groove of reserving between the tetrafluoro slide plate of plane.
Sliding agent flow through sphere (being plane of rotation) and plane (being slide surface) form connectivity structure, be diffused in the whole rubbing surface, with reach comprehensively, lubricant effect uniformly.
