Abstract
The utility model belongs to the technical field of sliding bearings of machinery products and relates to a thrust bearing structure. The thrust bearing structure comprises sector segments, support columns, limiting rings, a thrust ring and screws, and is characterized in that a hole is arranged on the back of each sector segment, grooves are arranged on two sides of each sector segment, each support column is a cylinder with one spherical end, the outer circle of each support column matches with the back hole of each sector segment, each limiting ring is a cylinder with a boss, a countersunk bolt mounting hole is arranged on the end face of the boss, and the thrust ring is a circular ring with bosses and is provided with screw holes and countersunk bolt mounting holes. The thrust bearing structure has the advantage that the sector segments are extremely convenient to mount by means of improving an existing thrust bearing limiting structure.
Description
Technical field
The utility model belongs to the sliding bearing technical field of machinery product, relates in particular to a kind of thrust slide bearing structure.
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 stability tilting-type structure preferably; Usually establish spherical bearing at the back side of fan-shaped tile fragment; Fan-shaped both sides are provided with curve bath, and are provided with stop screw, and are spacing with cooperating each fan-shaped tile fragment of curve bath through screw bosses.Though obvious this thrust-bearing is relatively simple for structure, be difficult for assembling.
Summary of the invention
The utility model is that a kind of thrust slide bearing structure is provided in order to address the above problem.
The scheme of the utility model is achieved in that a kind of thrust slide bearing structure, is made up of fan-shaped tile fragment, bearing post, position limit cycle, thrust circle, screw, it is characterized in that: the said fan-shaped tile fragment back side is provided with the hole, and both sides are provided with groove; Said bearing post is that an end is the cylinder of sphere, and its cylindrical cooperates with hole, the tile fragment back side; Said position limit cycle is the cylinder of band boss, and is provided with the countersunk screw mounting hole at raised head face; Said thrust circle is the annulus of band boss, and is provided with screw and countersunk screw mounting hole.
The beneficial effect of the utility model is: the improvement through to existing thrust slide bearing limit structure makes the installation of tile fragment very convenient.
Description of drawings
Fig. 1 is the structural representation of model utility.
Fig. 2 is the A-A sectional view of model utility.
Among the figure: 1, fan-shaped tile fragment, 2, bearing post, 3, position limit cycle, 4, screw, 5, the thrust circle.
Embodiment
Below in conjunction with accompanying drawing, the technological scheme of the utility model is further described:
Like Fig. 1, shown in Figure 2, fan-shaped tile fragment that bearing post 2 is housed 1 and position limit cycle 3 are placed on the relative position of thrust circle 5, use screw 4 fastening again.Owing to adopted this structure, it is very convenient to make thrust block pad install.
Claims (4)
