Abstract
The invention provides a tilting pad supporting structure. The tilting pad supporting structure comprises a tilting pad, two bearing covers, pin bolts and a bearing body, wherein the tilting pad is mounted in an inner hole of the bearing body; an arc surface protruding towards the center of the bearing body is arranged in the inner hole of the bearing body; a pad back of the tilting pad contacts with the arc surface of the inner hole of the bearing body; the two bearing covers are mounted at two ends of the bearing body; two pin bolt holes are respectively formed in two ends of the tilting pad and are connected with the bearing covers at two ends of the bearing body through the pin bolts. The tilting pad supporting structure has the advantages that the machining is simple, and the tilting pad is flexible to swing.
Description
Technical field
The present invention relates to a kind of watt sliding bearing that inclines, especially relate to a kind of watt supporting structure of inclining of watt sliding bearing that inclines.
Background technique
Oil whip problem when watt sliding bearing that can incline turns round for solving the rotor high-speed of sliding supported condition, the flexibility that can incline watt has a great impact the performance of bearing, so in Tilting Pad bearing, be all provided with corresponding structure so that tile fragment can axially can done the swing of several angle.Fig. 1 is the conventional watt supporting structure of inclining, and watt 1 the end face of can inclining is provided with circular arc boss, and bearing cap 2 is provided with the annular groove corresponding with circular arc boss, can incline to watt 1 by circular arc boss and bearing cap 2 annular grooves, coordinating spacing.Meanwhile, on bearing support 4, process screw hole, also watt 1 spacing to inclining by screw 3.There is following problem in this watt supporting structure of inclining: watt 1 watt of back of the body arc surface difficulty of processing that 1) can incline is larger; 2) bearing support 4 mounting screw 3 machining accuracies are high, and its center line requires to be positioned at the center of bearing support, in practical operation, reach this requirement more difficult, the deflection that becomes after easily causing screw 3 to be installed, can incline watt 1 flexible swinging of final impact, even making to incline watt 1 cannot swing; 3) watt 1 circular arc boss amount of finish that can incline is large, and processing is inconvenient.
Summary of the invention
In order to solve the problems of the technologies described above, the invention provides a kind of watt watt supporting structure of inclining that is easy to processing and flexible swinging of inclining.
The technical solution used in the present invention is: comprise can incline watt, two bearing caps, pin and bearing suppories, described incline watt be arranged in bearing support endoporus, in described bearing support endoporus, be provided with the protruding arc surface to bearing support center, watt back of the body that can incline watt contacts with the arc surface of bearing support endoporus, two described bearing caps are arranged on the two ends of bearing support, the two ends that can incline watt are respectively equipped with a pin hole, and two pin holes are connected with the bearing cap at bearing support two ends by pin respectively.
Above-mentioned inclines in watt supporting structure, and described bearing support endoporus is arc surface type.
Above-mentioned inclines in watt supporting structure, and the pin hole at the described watt two ends of inclining excessively coordinates with pin.
Above-mentioned inclines in watt supporting structure, and the pin hole diameter being connected with pin on described bearing cap is greater than the diameter of pin.
Above-mentioned inclines in watt supporting structure, and the described watt back of the body inclining watt is V-shaped.
Compared with prior art, the invention has the beneficial effects as follows: 1) Machining Arc face above bearing support endoporus of the present invention, than easy to operate in watt watt back Machining Arc face of can inclining; And watt watt back of the body that can incline do not need to process cambered surface, watt processing that makes to incline is simple; 2) of the present invention incline watt radially spacing by straight pin, flexible swinging, easy to process; 3) the present invention's watt stop screw for watt back of the body that can incline in watt supporting structure that do not have to incline, watt back of the body that can incline watt is processed into V-type, and watt flexibility that makes to incline has obtained greatly improving.
