Abstract
The utility model discloses a thrust knuckle bearing used for a bridge stay cable, which comprises an outer ring and an inner ring. The inner surface of the outer ring takes the shape of a bowl; the curvature centers of the circular arcs of the inner ring and the outer ring are located at the outer side of the bearing; a plurality of counter bores are perforated on the outer spherical surface of the inner ring; solid lubricant is arranged in the counter bores; and the inner ring and the outer ring are made of stainless steel. The thrust knuckle bearing is convenient to make, a plurality of counter bores are evenly perforated at certain interval on the outer spherical surface of the inner ring, and solid lubricant is arranged in the counter bores, so the sliding contact surfaces of the inner ring and the outer ring can be lubricated more sufficiently and evenly, thereby reducing the abrasion between the inner ring and the outer ring and improving the service life of the bearing. Both made of stainless steel 4Cr13, the inner ring and the outer ring of the thrust knuckle bearing can ensure the bearing to be free from rust and corrosion when the bearing works under humid water environment for a long time.
Description
Technical field
The utility model relates to a kind of thrust articulated bearing, belongs to technical field of bearings.
Background technique
The drag-line bridge is that girder directly is pulled in a kind of bridge on the bridge tower with many drag-lines, is the tower by pressure-bearing, the rope of tension and hold a kind of structural system that curved beam body combines.Usually be provided with plain radial bearing on the top of drag-line, be provided with thrust articulated bearing owing to will bear the load of bridge floor in the bottom of drag-line.Since drag-line under the effect of non-coplanar force axially and radially all small rotation can occur, so need the inner ring of bearing and the outer ring still can proper functioning under the bigger situation of nonconcentricity.Because bridge belongs to water surface building, the member on the bridge must satisfy not corrosion under the bigger environment of water surface humidity.In order to make thrust articulated bearing have good self-lubricating property, the general employing of prior art is sintered to copper powder on the inner ball surface of outer ring, and then plastics are compound on the copper powder sintering layer, but this scheme only is applicable to less joint shaft bearing, for large-sized joint shaft bearing, adopt this scheme to need main equipment, and complex process, cost is higher.
The model utility content
The purpose of this utility model overcomes above-mentioned the deficiencies in the prior art exactly, provide a kind of easily manufactured, lubrication state is good, the thrust articulated bearing of corrosion-resistant and long service life.
The utility model is achieved by the following technical programs.
A kind of thrust articulated bearing that is used for bridge cable comprises outer ring, inner ring, and the internal surface of described outer ring is bowl-shape, the centre of curvature of described inside and outside circle circular arc is in the bearing outside, wherein, on the outer spherical surface of inner ring, be drilled with several counterbores, in the described counterbore solid lubricant be housed.
Above-mentioned a kind of thrust articulated bearing that is used for bridge cable, wherein, the material of described outer ring and inner ring is a stainless steel.
The utility model is easily manufactured, on the inner ring outer spherical surface, evenly be drilled with several counterbores at regular intervals, solid lubricant is housed in counterbore, thereby can lubricate Internal and external cycle sliding contact surface more full and uniformly, reduced the wearing and tearing between the Internal and external cycle, thereby improved the working life of bearing.The Internal and external cycle material of the utility model thrust articulated bearing is stainless steel 4Cr13, not corrosion in the time of can guaranteeing that bearing is worked for a long time under the bigger aquatic environment of humidity.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Embodiment
The utility model comprises outer ring 1, inner ring 2, and the outer surface of inner ring 2 is an outer spherical surface, and the internal surface of outer ring 1 is an inner ball surface, and the sphere of inside and outside circle is complementary.The endoporus of inner ring 2 matches with drag-line, on the outer spherical surface of inner ring 2, evenly be drilled with several counterbores 3 at regular intervals, and in counterbore 3, solid lubricant is housed, make it can lubricate Internal and external cycle sliding contact surface more full and uniformly, reduced the wearing and tearing between the Internal and external cycle, thereby improved the working life of bearing.The material of outer ring 1 and inner ring 2 is stainless steel 4Cr13, not corrosion when having guaranteed that bearing is worked for a long time under the bigger aquatic environment of humidity.
In addition to the implementation, the utility model can also have other mode of executions, and all employings are equal to the technological scheme of replacement or equivalent transformation formation, all drop in the protection domain of the utility model requirement.
Claims (2)
