Abstract
The utility model discloses a middle and high speed large capacity hydroelectric set thrust bearing structure, including a bearing block 8, a thrust head 2, a thrust oil groove 12, an oil blocked tube 10, an oil cooler 6, a pillar screw 7 and a thrust bearing bush 14. A mirror plate 5 and the thrust head 2 are arranged individually; an oil resistant rubber strip 3 is arranged at the joint of the thrust oil groove 12 and an oil groove lid 4; an oil stabilization board 15 is arranged in the thrust oil groove 12; a tray 9 is arranged between the pillar screw 7 and the thrust bearing bush 14; an adjustment bolt of the pillar screw 7 is locked by means of a locked plate 11. The utility model has the advantages that the issues of the thrust bearing structure such as oil throwing and oil leakage can be resolved effectively; at the same time, the vibratility of hydroelectric set can be reduced so as to improve the reliability, safety and stability of hydroelectric set.
Description
Technical field
The utility model relates to a kind of dynamo bearing, particularly a kind of high speed large volume hydroelectric generating set thrust bearing structure.
Background technique
Thrust-bearing is one of the most key vitals of hydraulic turbine generator, it is most important to the convenience of the safety reliability of unit operation and Economy and installation and maintenance, the operation practice of domestic water turbine generator group shows: the accident that big-and-middle-sized hydraulic turbine generator causes because of thrust-bearing accounts for 55～70% of unit mechanical accident, bearing gets rid of oil, it is fixed that the greasy dirt that leakage of oil and mist of oil form covers generator, above the rotor coil, can reduce the dielectric strength of coil, hinder the normal heat radiation of winding, and mist of oil is dispersed into the operation factory building also can endanger the healthy of field personnel.
Summary of the invention
The purpose of this utility model promptly is to overcome the shortcoming of prior art, provides a kind of and can overcome the thrust-bearing that hydraulic generator thrust bearing gets rid of oil, leakage of oil and reduces unit, is applicable to high speed large capacity hydroelectric generator group.
Goal of the invention of the present utility model is achieved through the following technical solutions: a kind of high speed large volume hydroelectric generating set thrust bearing structure, comprise thrust metal, thrust collar, thrust bearing oil sump, the retaining oil pipe, oil cooler, pillar screw, thrust bearing shoe, thrust metal is fixed on the upper spider, pillar screw is fixed on the thrust metal, pillar screw is supported thrust bearing shoe, thrust collar is fixed on the generator shaft by ring key, thrust bearing oil sump and retaining oil pipe constitute fuel reserve tank, thrust bearing oil sump covers with oil groove, it is characterized in that runner plate and thrust collar branch are arranged, avoid the mating face corrosion of thrust collar and runner plate, prevent unit axis generation deviation and cause the unit operation vibrations to strengthen, thrust bearing oil sump and oil groove lid commissure are provided with the oil-proof rubber bar, be provided with oil-stabilizing plate in the thrust bearing oil sump, thrust bearing oil sump be provided with outward sealing cover prevent the thrust bearing oil sump leakage of oil and inside and outside get rid of oil.
Be provided with pallet between pillar screw and the thrust bearing shoe, the adjusting bolt of pillar screw locks with lockplate, helps to improve the stability of unit operation.
The material of thrust collar is ZG20SiMn, and the material of runner plate is No. 45 forged steel, and the rigidity of thrust collar and runner plate is strong, produces periodic wavy distortion when avoiding moving and causes the contact corrosion on the mating face of thrust collar and runner plate.
Thrust bearing shoe is a plastic made tile, the plastic made tile friction factor is very little, abrasion loss is very little, the power of attrition is less, do not need the axle insulation, especially the withstand voltage temperature resistant capability of plastic made tile is stronger, there is the tile kilning problem hardly, even can cut off the water supply at cooler and move down, thereby effectively reduce the unit operation fault.
From top narration as can be seen, a kind of high speed large volume hydroelectric generating set thrust bearing structure that the utility model provides, can effectively solve thrust-bearing and get rid of oil, leakage of oil problem, vibratility when reducing unit operation has improved operational reliability, Security and the stability of unit.
