Abstract
The utility model belongs to sliding bearing technical field, particularly relate to a kind of thrust slide bearing, be made up of some fan-shaped tile fragments, it is characterized in that: described fan-shaped tile fragment end face is provided with toroidal cavity, and make the tile fragment end face in groove lower than the outer tile fragment end face 0.02mm of groove, groove floor is provided with hole, and hole set by a side plane of this hole and tile fragment is communicated, and the aperture of described side plane institute apertured is provided with connecting thread.Its beneficial effect is: by adopting such scheme, not only efficiently reducing impact when high-pressure oil chamber normally uses bearing, and improving its top lifting performance.
Description
Technical field
The utility model belongs to sliding bearing technical field, particularly relates to a kind of thrust slide bearing.
Background technique
As everyone knows; the bearing capacity of thrust slide bearing; depend primarily on runner plate to move on its thrust face produced oil-film force; but because unit is when starting shooting and shut down; the motion speed of runner plate is lower, cannot form enough oil-film forces, thus causes bearing damage; therefore, usually high pressure oil jack-up function need be provided with at thrust bearing surface.Existing method is: by high pressure oil being introduced the grease chamber set by bearing surface, thus jack-up runner plate, described grease chamber is circular flat bottom outlet.But due to the setting of circular grease chamber, the usability tools such as the bearing capacity of bearing when normal operation are had a certain impact, therefore, how to guarantee its high pressure oil jack-up ability, and not affect bearing usability be that we need the problem of solution badly.
Summary of the invention
The utility model provides a kind of thrust slide bearing.
Scheme of the present utility model is achieved in that a kind of thrust slide bearing, be made up of some fan-shaped tile fragments, it is characterized in that: described fan-shaped tile fragment end face is provided with toroidal cavity, and make the tile fragment end face in groove lower than the outer tile fragment end face 0.02mm of groove, groove floor is provided with hole, and hole set by a side plane of this hole and tile fragment is communicated, the aperture of described side plane institute apertured is provided with connecting thread.
The beneficial effects of the utility model are: by adopting such scheme, not only efficiently reducing impact when high-pressure oil chamber normally uses bearing, and improving its top lifting performance.
Accompanying drawing explanation
Fig. 1 is structural drawing of the present utility model.
Fig. 2 is the A-A sectional view of Fig. 1.
In figure: 1, tapped hole, 2, oil inlet hole, 3, annular groove.
Embodiment
Below in conjunction with accompanying drawing, the technical solution of the utility model is further described:
As Fig. 1, shown in Fig. 2, thrust slide bearing is made up of some fan-shaped tile fragments, described tile fragment end face is provided with annular groove 3, groove floor is provided with oil inlet hole 2, and communicates, during work with tapped hole 1 set by tile fragment side, high pressure oil by oil inlet hole 2, enters the function that annular groove 3 carries out jack-up runner plate from tapped hole 1.Because the tile fragment end face in groove 3 is lower than the outer tile fragment end face 0.02mm of groove, when high pressure oil enters, oil-filled rapidly, add the bearing capacity of high-pressure oil chamber; When normally running, and between runner plate, form thrust oil film.Meanwhile, due to the setting of annular groove 3, fluid small volume needed for it, under high pressure carrying, reduces fluid volume compression amount, improves its top lifting load-carrying properties.
