Abstract
The utility model belongs to the technical field of sliding bearings of mechanical products, and relates to a thrust sliding bearing, which comprises a fan-shaped tile, a limit ring and a support column, and is characterized in that a cylindrical lug boss and an installing screw hole are arranged on the back surface of the fan-shaped tile, the limit ring is a circular ring provided with an installing counter bore in the end face, an inner holes is matched with the cylindrical lug boss on the back surface of the fan-shaped tile, the support column is a cylinder with a spherical surface on one end face, and the excircle of the support column is matched with the inner hole of the limit ring. The thrust sliding bearing has the beneficial effects that through an improvement of the traditional structure, processing errors and assembling errors of all parts are more easily regulated, precision is improved, and 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 thrust slide bearing.
Background technique
Thrust slide bearing is widely used in 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 is made up of the fan-shaped tile fragment of some dribbling surface bearing posts usually; Be connected with bearing post through being provided with at the tile fragment back side with the hole of bearing post transition fit; When therefore it uses, because the machining error and the assembly error of tile fragment and spherical bearing post make the difficult height that reaches unanimity of each tile fragment assembly; Cause the tile fragment wearing and tearing inhomogeneous, influence its working life.
Summary of the invention
The utility model is that a kind of thrust slide bearing 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, is made up of fan-shaped tile fragment, position limit cycle and bearing post, it is characterized in that: the said fan-shaped tile fragment back side is provided with cylinder boss and screw is installed; Said position limit cycle is that end face is provided with the annulus that counterbore is installed, and endoporus cooperates with segmental pad back of the body cylinder boss; Said bearing post one end face is a sphere, the cylinder that cylindrical and position limit cycle endoporus match.
The beneficial effect of the utility model is: through the improvement to existing structure, make the machining error of each parts and assembly error be prone to adjustment, improve precision, prolong the working life of bearing.
Description of drawings
Fig. 1 is the structural representation of model utility.
Among the figure: 1, tile fragment, 2, position limit cycle, 3, bearing post, 4, bolt.
Embodiment
Below in conjunction with accompanying drawing, the technological scheme of the utility model is further described:
As shown in Figure 1, position limit cycle 2 is contained on the tile fragment 1 through bolt 4, reinstalls bearing post 3, therefore behind the height of thickness that detects each tile fragment 1 and bearing post 3, can improve the precision of thrust slide bearing through the grinding to tile fragment back side cylinder boss.
Claims (3)
