Abstract
A cooled bearing capable of reducing the temperatures of a bearing and a rotor and prolonging the service life of the bearing and the rotor comprises two semicircular interlocked bearing bodies, the outer rings of the two bearing bodies are respectively provided with circumferentially arranged oil slots, the bearing bodies are respectively provided with a plurality of threaded radial step holes connected with the oil slots, the radial step holes are respectively alternately provided with adjusting screws and through oil screws through threads, the adjusting screws and the through oil screws traverse out of the inner rings of the bearing bodies, and the traversing ends of the through oil screws are provided with oil nozzles; and arc-shaped tilting pads are respectively arranged on the inner rings of the bearing bodies and positioned among the oil nozzles, and the tilting pads are respectively provided with groove holes corresponding to the adjusting screws. The lower portions of the bearing bodies are provided with two cooling holes I. One of the below adjusting screws is a through oil adjusting screw, and cooling holes II are arranged between one end of the tilting pad corresponding to the through oil adjusting screw and the slot holes.
Description
Technical field
The present invention relates to the cooled bearing on a kind of steam turbine.
Background technology
Bearing is the important composition parts of steam turbine, bearing is used for undertaking the weight of rotor and the out-of-balance force of rotation, and determine the radial position of rotor, to keep rotor center of rotation consistent with central cylindrical, thus ensureing that the radial clearance of the stationary parts such as rotor and cylinder, packing, dividing plate is correct.Developing to direction large-scale, efficient along with oil, chemical industry etc. produce, steam parameter and the power grade scope of industrial steam turbine also correspondingly improve, and propose requirements at the higher level hence for bearing.Being continuously increased of Steam Turbine capacity, causes the increase of journal diameter, and after journal diameter increases, axle journal linear velocity increases therewith, and frictional dissipation increases accordingly.After linear velocity reaches certain numerical value, cause bearing and friction rotor to dramatically increase, make bearing and rotor fast temperature raise, sometimes even over the temperature upper limit that bearing and rotor allow, cause the damage of bearing and rotor, shorten the service life of bearing and rotor.
Summary of the invention
The present invention is the existing issue in order to solve above-mentioned existence, it is provided that a kind of cooled bearing reducing bearing and temperature of rotor, extending its service life.
The technical solution of the present invention is:
A kind of cooled bearing, it is characterized in that the bearing body including two semi-circulars and make-up placement, it is provided with oil groove circumferentially two bearing body outer rings, described bearing body is laid with multiple communicating with oil groove and screwed radial direction shoulder hole, described radial direction shoulder hole is mounted alternately with adjustment screw and logical whelk nail respectively through screw thread, described adjustment screw and logical whelk nail pass bearing body inner ring, and described logical whelk nail traversing through end is provided with atomizer；Described bearing body inner ring is respectively equipped with the tilting pad of arc between each atomizer, described tilting pad is respectively equipped with the slotted eye corresponding with adjusting screw.
It is provided with two Cooling Holes I in described bearing body bottom.
One be wherein positioned below adjusts screw and adjusts screw for logical oil, adjusts at the logical oil of correspondence and is provided with Cooling Holes II between tilting pad one end and the described slotted eye of screw.
The invention has the beneficial effects as follows:
When 1, installing, this cooled bearing is enclosed within rotor by tilting pad, enables rotor to drive tilting pad to swing, rotation angled with bearing body, meet particular job situation needs.
2, bearing body outer ring is provided with oil groove circumferentially, and is laid with multiple communicating with oil groove and screwed radial direction shoulder hole on bearing body, and radially shoulder hole is provided with logical whelk nail by screw thread, and logical whelk nail traversing through end is provided with atomizer；Lubricating oil enters the gap between tilting pad and rotor, tilting pad and rotor to play the effect of lubrication, cooling, extends the service life of bearing and rotor through oil groove, radially shoulder hole, logical whelk nail and atomizer successively.
3, bearing body bottom arranges two Cooling Holes I；One be wherein positioned below adjusts screw and adjusts screw for logical oil, adjusts at the logical oil of correspondence and is provided with Cooling Holes II between tilting pad one end and the slotted eye of screw.By lubricating oil, tilting pad and rotor are played the effect of lubrication, cooling further, extends the service life of bearing and rotor.
