Description

A kind of hyperboloid tilting bush supporting structure
Technical field
The utility model relates to a kind of tilting bush sliding bearing, especially relates to a kind of tilting bush supporting structure of tilting bush sliding bearing.
Background technique
Oil whip problem when tilting bush sliding bearing operates for the rotor high-speed solving sliding supported condition, in tilting bush sliding bearing, the flexible swing of tile fragment can solve the effective measures of oil whip just, but the flexibility of tile fragment swing and stability also need emphasis to consider.Existing tilting bush supporting structure shown in Fig. 1,2, the end face of tilting bush 1 is provided with circular arc boss, and bearing cap 2 is provided with the annular groove corresponding with circular arc boss, and tilting bush 1 coordinates spacing by circular arc boss and bearing cap 2 annular groove.Meanwhile, bearing support 4 processes screw hole, also spacing to tilting bush 1 by screw 3.There is following problem in this tilting bush supporting structure: 1) the tilting bush 1 watt back of the body belongs to point cantact with bearing support endoporus, and the tilting bush 1 watt back of the body is high with the hardness requirement of bearing support; 2) stability that coordinates with bearing support of tilting bush is not high.
Summary of the invention
In order to solve the problems of the technologies described above, the utility model provides a kind of can make tilting bush flexible swinging and the high tilting bush supporting structure of stability.
The technical solution adopted in the utility model is: comprise tilting bush, bearing support and pin, the two ends of described bearing support are separately installed with a bearing cap, described tilting bush is arranged in bearing support inner chamber, the both ends of the surface of tilting bush is respectively equipped with a pin, and two pins are coaxial; Corresponding to the pin on tilting bush end face, the bearing cap at bearing support two ends is respectively equipped with pin-and-hole, pin is arranged in the pin-and-hole on bearing cap; Described bearing support endoporus sidewall is provided with annular groove, and the cross section of groove is curved; Corresponding to annular groove, a watt back for tilting bush is provided with projection, and protruding cross section is curved.
In above-mentioned hyperboloid tilting bush supporting structure, the two ends of described tilting bush are respectively equipped with pin hole, and two pin holes are coaxial; Two pins are arranged in two pin holes respectively, pin and pin hole transition fit.
In above-mentioned hyperboloid tilting bush supporting structure, on described bearing cap, the diameter of pin-and-hole is greater than the diameter of the pin at tilting bush two ends.
Compared with prior art, the beneficial effects of the utility model are: 1) the utility model is spacing by pin radial direction, pin hole on bearing cap is greater than the diameter of pin, tilting bush can swing flexibly, the projection of tilting bush of the present utility model watt back coordinates with the annular groove cambered surface of bearing support endoporus, and stability is high; 2) a tilting bush of the present utility model watt back of the body is contacted by cambered surface with between bearing support endoporus, and the hardness requirement of the tilting bush watt back of the body and bearing support is lower.
Accompanying drawing explanation
Fig. 1 is the plan view of existing tilting bush supporting structure.
Fig. 2 is A-A sectional view in Fig. 1.
Fig. 3 is plan view of the present utility model.
Fig. 4 is B-B sectional view in Fig. 3.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
As shown in Figure 3,4, the utility model comprises tilting bush 1, two bearing caps 2, pin 5 and bearing suppories 4, and two described bearing caps 2 are arranged on the two ends of bearing support 4; Described tilting bush 1 is arranged in the endoporus of bearing support 4, and the two ends of tilting bush 1 are respectively equipped with pin hole, and two pin holes are coaxial, and being respectively equipped with pin 5 in two pin holes, is transition fit between pin 5 and pin hole.Corresponding to the pin 5 at tilting bush 1 two ends, described bearing cap 2 is provided with pin-and-hole 21, and pin 5 is arranged in pin-and-hole 21, and the diameter of pin-and-hole 21 is greater than the diameter of pin 5.The endoporus sidewall of described bearing support 4 is provided with annular groove 41, and the cross section of annular groove 41 is curved, and corresponding to annular groove 41, a watt back for tilting bush 1 is provided with protruding 11, and the cross section of protruding 11 is curved.Protruding 11 contact with the annular groove 41 of bearing support 4 endoporus.
The projection 11 of watt back of tilting bush 1 of the present utility model contacts with the annular groove 41 of bearing support 4 endoporus, tilting bush 1 is arranged in the pin-and-hole 21 on bearing cap 2 radial spacing by pin 5, and the diameter of pin-and-hole 21 is greater than the diameter of pin 5, tilting bush 1 of the present utility model can be swung flexibly.The utility model needs Machining Arc face 41 on bearing support 4 endoporus, and this is more easy to operate than watt back Machining Arc face at tilting bush 1, and the projection 11 of tilting bush 1 watt of back coordinates with the annular groove cambered surface of bearing support 4, and operation stability is high.
