Abstract
The utility model belongs to the technical field of sliding bearings of mechanical products and relates to an elastic thrust sliding bearing, which comprises circular tiles, an O-shaped ring, a belleville spring and a support ring, and is characterized in that babbitt metals are casted on the surfaces of the circular tiles, a cylindrical lug boss is arranged on the back surface of each circular tile, an O-shaped ring groove is arranged on the lug boss, the support ring is a combination of two semicircular rings, a plurality of annular shallow grooves are arranged on the surface of the circular ring for limiting the position of the belleville spring, and a hole is arranged in an annular hole and matched with the lug boss on the surface of each tile. The elastic thrust sliding bearing has the advantages that through improvement of the traditional structure, loads of all tiles are uniform by adopting an elastic part, the bearing capacity of the bearing in unit area is enhanced, and the performance of the thrust bearing is greatly improved, thus the service life of the bearing is prolonged.
Description
Technical field
The utility model belongs to the sliding bearing technical field of machinery product, relates in particular to a kind of elastic thrust sliding bearing.
Background technique
Thrust slide bearing is the vitals of rotating machinery units such as steam turbine, gear-box, and it carries the unit load through the dynamic pressure oil film power that forms between tile fragment surface and the unit thrust disc surface.Existing thrust slide bearing generally adopts the back side of fan-shaped tile fragment to establish the tilting-type structure of spherical bearing; Because the thrust-bearing manufacturability of this structure is poor; The conformity of each tile fragment height of processing back is difficult to control, causes the suffered load of each tile fragment inhomogeneous, the aggravation bearing wear; The tile fragment temperature rises, and is bigger to the influence in working life of bearing.
Summary of the invention
The utility model is that a kind of elastic thrust sliding bearing is provided in order to address the above problem.
The scheme of the utility model is achieved in that a kind of elastic thrust sliding bearing; Form by circular tile fragment, O shape circle, butterfly spring and bearing ring; It is characterized in that: said circular tile fragment surface is cast with Babbitt, and the back side is provided with cylinder boss, and establishes O shape ring recess at boss; Said bearing ring is the combination of two semicircular ring, is provided with some annular shallow slots on the annulus surface limiting the butterfly spring position, and is provided with the hole in annular center and cooperates with tile fragment back side boss.
The beneficial effect of the utility model is: through the improvement to existing structure, utilize elastic member to make each tile fragment load even, strengthened the bearing capacity of bearing unit area, greatly improved the performance of thrust-bearing, thereby prolong the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of model utility.
Among the figure: 1, circular tile fragment, 2, O shape circle, 3, butterfly spring, 4, bearing ring.
Embodiment
Below in conjunction with accompanying drawing, the technological scheme of the utility model is further described:
As shown in Figure 1, circular tile fragment 1 and butterfly spring 3 that O shape circle 2 is housed are contained on the bearing ring 4, during work; Because the effect of the elastic force of butterfly spring; Make the suffered load of each tile fragment even, thereby strengthened the bearing capacity of bearing unit area, prolong the working life of bearing.
Claims (2)
1. an elastic thrust sliding bearing is made up of circular tile fragment, O shape circle, butterfly spring and bearing ring, it is characterized in that: said circular tile fragment surface is cast with Babbitt, and the back side is provided with cylinder boss, and establishes O shape ring recess at boss.
2. a kind of elastic thrust sliding bearing as claimed in claim 1; It is characterized in that: said bearing ring is the combination of two semicircular ring; Be provided with some annular shallow slots on the annulus surface limiting the butterfly spring position, and be provided with the hole in annular center and cooperate with tile fragment back side boss.
