Abstract
The utility model relates to a sliding bearing which includes a bearing seat and an end cover with sealing device which is arranged at the two ends of the bearing seat which is provided with a group of thrust bushing being subject to the axial thrust and radial bushing being subject to the radial force; the thrust bushing (ten blocks for one group) presenting ring-shaped is arranged on a shaft shoulder ring surface of a rotation shaft; the external ring of the thrust bushing is provided with an oil collecting shield, the upper part is provided with an oil leakage mouth where the lubricant flows out after operation; the oil collecting shield is fixedly connected with the radial bushing. The utility model has simple structure and good practical effect, and is mainly applied to forcing lubrication sliding bearing of hydraulic generator group.
Description
Technical field
The utility model relates to a kind of bearing, especially a kind of sliding bearing that is used for the enforced lubricating of hydroelectric power unit.
Background technique
On middle-size and small-size hydroelectric power unit, sliding bearing is very important constituent element, and its stability and Security are directly connected to the runnability of unit.Sliding bearing comprises bearing support, radially bearing shell, thrust bearing shoe, end cap, selflubricating oil supply system etc.Such structure is fit to the less unit of low, the radial and axial duty ratio of rotating speed, the situation that can not bear big load and high speed rotating shaft.In the practical application, axially, radial load is more than 20 tons, 1000 rev/mins of rotating speeds, this kind self-lubricating structure significant discomfort of the prior art is closed this kind requirement.
Summary of the invention
Originally the purpose that is model utility is a kind of simple in structure, stable sliding bearing of design.The technical solution of the utility model is so to realize:
A kind of sliding bearing of enforced lubricating, comprise bearing support (5) and be arranged on the end cap (6) of the band seal arrangement at its two ends, end cap (7), establish the thrust bearing shoe (2) of one group of bearing axial pushing force and the radially bearing shell (3) of bearing radial force in the bearing support (5), thrust bearing shoe (2) and radially bearing shell (3) respectively by low pressure oil inlet pipe (25), high pressure oil inlet pipe (16) carries out independent oil supply to it, between the thrust bearing shoe (2) by spraying fuel feeding each other, thrust bearing shoe is the belt axle that is arranged in for (2) one group 10 on anchor ring, establish oil pooling hood (8) in its outer ring, described oil pooling hood (8) top is provided with the drain tap (18) that the lubricant oil that makes after the work flows out, oil pooling hood (8) is fixedly connected with bearing shell (3) radially, and high pressure oil inlet pipe (16) carries out independent oil supply by oil pipe (4) and the high pressure oilhole (19) that is located on the bearing shell (3) radially to bearing shell (3) radially.
As preferably, radially bearing shell (3) adopts sphere to cooperate with bearing support (5).
The utility model mainly improves lubrication system in the prior art, changes the enforced lubricating system into by original self lubricating system, and this kind is simple in structure, and actual effect is good, has solved the high time operation problem of unstable of big load and rotating speed.
Description of drawings
Accompanying drawing 1 is a kind of structural representation of the present utility model;
Accompanying drawing 3 is a kind of surface structure schematic representation of Fig. 1.
Embodiment
Below in conjunction with accompanying drawing,, the technical solution of the utility model is described in further detail by embodiment.
With reference to the accompanying drawings 1, accompanying drawing 3, the sliding bearing of enforced lubricating, comprise bearing support (5) and be arranged on the end cap (6) of the band seal arrangement at its two ends, end cap (7), establish the thrust bearing shoe (2) of one group of bearing axial pushing force and the radially bearing shell (3) of bearing radial force in the bearing support (5), in conjunction with the accompanying drawings 2, one group 10 thrust bearing shoes (2) of band wearing layer are arranged on the rotating shaft shaft shoulder anchor ring ringwise, establish oil pooling hood (8) in its outer ring, oil pooling hood (8) top is provided with the drain tap (18) that the lubricant oil that makes after the work flows out, oil pooling hood (8) is fixedly connected with bearing shell (3) radially, and the lubricant oil after the work flows out from the drain tap (18) on oil pooling hood (8) top.
The radially bearing shell (3) of band wearing layer adopts sphere to cooperate with bearing support (5).
With reference to the accompanying drawings 1 and accompanying drawing 2, thrust bearing shoe (2) carries out independent oil supply by low pressure oil inlet pipe (25) and low pressure oilhole (19) to it, fuel delivery can be regulated separately, by spraying fuel feeding each other, guarantees evenly cooling of every thrust bearing shoe (2) between the thrust bearing shoe (2).Radially bearing shell (3) forces fuel feeding by high pressure oil inlet pipe (16), oil pipe (4) and the high pressure oilhole (9) that is located on the bearing shell (3) radially to bearing shell (3) radially, and fuel delivery also can be regulated separately.When rotating shaft ran up, the high pressure oil that high pressure oilhole (9) comes out made radially that bearing shell (3) better forms oil film, and its radial load that bears can increase on original basis greatly, satisfied the radially actual requirement of big load.
Claims (2)
1, a kind of sliding bearing of enforced lubricating, comprise bearing support (5) and be arranged on end cap (6), the end cap (7) of the band seal arrangement at its two ends, establish the thrust bearing shoe (2) of one group of bearing axial pushing force and the radially bearing shell (3) of bearing radial force in the bearing support (5), it is characterized in that (2) one groups 10 of described thrust bearing shoes are arranged on the rotating shaft shaft shoulder anchor ring ringwise, establish oil pooling hood (8) in its outer ring, described oil pooling hood (8) top is provided with the drain tap (18) that the lubricant oil that makes after the work flows out, and oil pooling hood (8) is fixedly connected with bearing shell (3) radially.
2, the sliding bearing of a kind of enforced lubricating according to claim 1 is characterized in that described radially bearing shell (3) and bearing support (5) adopt sphere to cooperate.
