Abstract
The invention discloses a combined radial sliding bearing with a tilting pad and a fixed pad. The combined radial sliding bearing with the tilting pad and the fixed pad comprises an upper half bearing 1 and a lower half bearing 2, wherein the upper half bearing 1 comprises a fixed pad 3; the lower half bearing 2 comprises a bearing body 9; a tilting pad seat 6 is arranged in the bearing body 9; the tilting pad 5 is arranged on the tilting pad seat 6; the two sides of the tilting pad seat 6 are provided with a tilting pad baffle plate 4 and a tilting pad baffle plate 10 in the axial direction; and when the combined radial sliding bearing works, the tilting pad 5 can swing freely on the spherical point of the bearing body 9 so as to regulate the position of a pad and form an optimal lubricating oil wedge between the bearing surface of the pad and the surface of a shaft journal. The combined radial sliding bearing with the tilting pad and the fixed pad has the advantages of good bearing capacity, high stability, strong adaptability and the like, and can be widely applied to high-speed rotating machines.
Description
Technical field
The present invention relates to a kind of radial sliding bearing, especially a kind of combined radial sliding bearing that is used to support high speed rotor with tilting pad and fixed bush segment.
Background technique
The tilting-pad radial sliding bearing has high stability, thereby is widely used in the various rotating machineries.During the tilting-pad radial bearing working, each tile fragment in the bearing can form a plurality of oil film wedges with the variation of bearing load around its spot wobble around axle journal, and tile fragment has brought the superregulated property of tilting-pad bearing around the swing of its fulcrum just.The tilting-pad radial bearing not only has bigger bearing capacity and lower friction power loss, and can bear the radial load of all directions.In addition, tilting-pad bearing also has advantages such as simple in structure, that maintenance is convenient, tile fragment interchangeability is strong.But the tile fragment that is in tilting-pad radial sliding bearing top is bearing load not, thereby when bearing working, " unloading " phenomenon usually can take place the tile fragment at top, counter-rotating occurs and the tile kilning accident takes place.Therefore, often need to install anti-reverse mechanism in the tilting-pad radial sliding bearing, this has increased the complexity of bearing structure.In addition, because common tilting pad can only when axial deflection takes place rotor, can be close between axle journal and the tile fragment and cause wearing and tearing along radially wobbling, the long-term stability that reduces the working life of bearing and influence rotor-support-foundation system is moved.
Summary of the invention
In order to overcome above-mentioned the deficiencies in the prior art, the invention provides a kind of combined radial sliding bearing with tilting pad and fixed bush segment, this combination bearing not only can be eliminated " unloading " counter-rotating of bearing top tile fragment, avoid the generation of tile kilning accident, can also realize the swing of tilting pad along any direction, it is parallel that tile fragment and axle journal are remained, the wearing and tearing that are close to when avoiding rotor that axial deflection takes place effectively between axle journal and the tile fragment have the advantage that bearing capacity is good, stability is high, adaptivity is strong.
To achieve these goals, the technological scheme that the present invention takes is: a kind of combined radial sliding bearing with tilting pad and fixed bush segment, include a bottom half-bearing 2 going up half bearing 1 and its underpart, last half bearing 1 includes fixed bush segment 3, bottom half-bearing 2 includes bearing support 9, be provided with tilting pad watt seat 6 in the bearing support 9, tilting pad watt seat 6 is provided with tilting pad 5, the both sides of tilting pad watt seat 6 are provided with tilting pad block 4 and tilting pad block 10 at axial direction, prevent that tilting pad watt seat 6 from coming off from bearing support 9.
The bottom of described tilting pad watt seat 6 is provided with liner 7, and liner 7 cooperates with bearing support 9 by bulb straight pin 8.
Described bottom half-bearing 2 includes two tilting pads 5.
Described bulb straight pin 8 is the plane with the abutting end of bearing support 9, with the abutting end of liner 7 be sphere.
The invention has the beneficial effects as follows: on the one hand, the tile fragment at radial bearing top is designed to " unloading " counter-rotating that fixed bush segment 3 can be eliminated this tile fragment, avoid the generation of tile kilning accident, the oil film pressure that forms on the fixed bush segment 3 can also suppress the vibration of axle journal in the vertical direction to a certain extent, and combined radial sliding bearing can keep the tilting-pad radial sliding bearing in all advantages that aspect of performance had; On the other hand, cooperate for the sphere fulcrum between tilting pad 5 and the bearing support 9, tilting pad 5 can be freely swung along any direction, guarantee that fully the supporting plane of tilting pad 5 can adapt to the variation of rotor motion, and all the time with the axle journal keeping parallelism, the wearing and tearing that are close in the time of can avoiding rotor that axial deflection takes place effectively between axle journal and the tile fragment can fully guarantee the long-term stability operation of rotor.
