Abstract
The utility model discloses a water lubricating pilot bearing of a vertical turbine. The water lubricating pilot bearing comprises a shaft (4), a bearing support (1), a Cellon shaft sleeve (3) around the periphery of the shaft (4), and a bearing outer sleeve (2) closely adjacent to the Cellon shaft sleeve (3). The Cellon shaft sleeve (3) comprises a plurality of Cellon bearing bushes, wherein two water storing grooves are arranged on the bush surface of each Cellon bearing bush; a bearing clearance (6) between the lower part of the bush surface of each Cellon bearing bush and the shaft (4) ranges from 0.45 mm to 0.55 mm; and the Cellon shaft sleeve (3) is adhesively bonded on the bearing outer sleeve (2) made of a corrosion-proof metal material. According to the utility model, the structures of the existing metal and rubber shaft sleeves are improved, i.e. the Cellon shaft sleeve is utilized to replace the traditional metal and rubber shaft sleeves, so that the service life of the bearing is prolonged, and the non-failure operation time of equipment is prolonged.
Description
Technical field
The utility model relates to a kind of guide bearing of water turbine, and particularly a kind of guide bearing that is applied on the vertical turbine belongs to water turbine accessory technical field.
Background technique
The main shaft guide bearing of domestic present large vertical water turbine machine adopts metal bearing or rubber bush bearing mostly; Metal bearing is because processing and assemble and bad the tile kilning phenomenon often takes place in use, and the rubber bush bearing friction factor is big, bearing capacity is low, it is aging to be prone to, and water turbine is in operation; Rubber bush bearing is more serious to the wearing and tearing of hydraulic turbine main shaft; Even the main shaft axle journal is cracked, and threaten the safe operation of unit, reduce the reliability of system.
The model utility content
The technology of the utility model is dealt with problems and is: the deficiency that overcomes existing technology; Adopt the imperial material of match,, a kind of vertical turbine water lubrication guide bearing is provided through existing structure is improved; Improve the working life of bearing, prolonged the Mean time to failure of equipment.
The technical solution of the utility model is: the vertical turbine water lubrication guide bearing that the utility model provides; Comprise axle, bearing bracket; Also comprise being centered around the imperial axle sleeve of said axial match, and with the imperial axle sleeve of said match next-door neighbour's bearing outside, said match dragon axle sleeve is made up of the some imperial bearing shells of match; The tiling of the every imperial bearing shell of match is provided with the twice aqua storage tank, is provided with the bearing play between its tiling and the said axle.
Preferably, matching the tiling of imperial bearing shell and the bearing play between the said axle is 0.45-0.55mm.
Further, the imperial axle sleeve of said match is made up of 16 imperial bearing shells of match.
Watt back of the body of the every imperial bearing shell of match is formed by the corrosion resistant plate manufacturing, and surface coverage is matched imperial material.
The imperial axle sleeve of said match is bonded on the said bearing outside.
Said bearing outside is installed on the said bearing bracket through bolt.
Said bearing outside adopts the corrosion resistant metal material.
Further, this guide bearing also comprises the bearing lubrication water tank that is installed on the top cover.Preferably, said bearing lubrication water tank is installed on the said top cover through anti-heavy bolt.
The utility model compared with prior art has following advantage:
(1) the vertical turbine water lubrication guide bearing of the utility model; Through the structure of existing metal axle sleeve and rubber axle sleeve is improved, adopt the imperial axle sleeve of match to replace traditional metal axle sleeve and rubber axle sleeve, match imperial axle sleeve and form by the some imperial bearing shells of match; The tiling of the every imperial bearing shell of match is provided with the twice aqua storage tank; Be easy to tiling and set up lubricating water film, match between tiling and the axle of imperial bearing shell and be provided with the bearing play, than existing metal axle sleeve and rubber axle sleeve and spool between the bearing play little; Thereby make lubricated water be difficult for flowing away fast, practiced thrift bearing lubrication water.
(2) the vertical turbine water lubrication guide bearing of the utility model; Through adopting the corrosion resistant metal overcoat; A kind of ternary transcrystallization of liner thermosetting resinous polymer-Sai Long; The match dragon gets into particle or the axle die misalignment also has significant compensating action, has greatly improved the working life of bearing, has prolonged the Mean time to failure of equipment.
