Abstract
Radial thrust bearing of improved generation relates to a hydroelectric set spare, especially a radial thrust bearing. Including bearing frame, bearing cap, left end lid, pay thrust disc, bearing body, axle bush, thrust tile, main thrust disc, right -hand member lid, wherein from the left hand right side in proper order with the left end lid, pay thrust disc, bearing body, axle bush, thrust tile, main thrust disc, right -hand member and cover the suit on the turbine shaft and install on the bearing frame its characterized in that after the cooling chamber of bearing frame not changing under the former cooler water cold core size state, has reduced cooler inner chamber diameter. Through realizing to bearing body and the some institutional advancements of oily cold and hot exchange that the circulating oil cooling is abundant, the bearing body is the oil return not.
Description
Technical field
The utility model relates to a kind of hydraulic turbine generator assembly, especially a kind of radial-thrust bearing.
Background technique
Existing water turbine radial-thrust bearing due to oil cooling heat exchange part oil pocket and water-cooled core outside dimension difference large, condenser chamber oil inlet and outlet is entered by two ends, and centre goes out, and this design deficiency makes deep fat wherein can not all be cooled in cooling; Oil temperature declines not enough; Again because bearing support support thrust bearing shoe valve, thrust disc position arrange defect, part cold oil is caused directly to reflux through thrust bearing shoe valve, namely there is part cold oil before not arriving bearing shell and axle is cooled, just be back to cooling chamber through thrust bearing shoe valve, can not cool axis body and the abundant fuel feeding of bearing shell part, this part axis body is caused to cool not enough heating, oil temperature high (more than 65 °) when bearing runs, such unit runs for a long time under improper oil temperature operating mode, has a strong impact on radial watt, working life of thrust bearing shoe valve and lubricant oil; Separately because thrust disc diameter is large and bearing (ball) cover axis hole, will shift out axle assembly during maintenance, need to remove bearing cap, could realize, dismounting is very inconvenient, and labor intensity is large and work efficiency is low.
Summary of the invention
The utility model object is: provide a kind of modified model radial-thrust bearing, through realizing recycle oil cooling to bearing support and oil cooling heat exchange part architecture advances fully, bearing support not oil return.
Technical solutions of the utility model are: modified model radial-thrust bearing, comprise bearing support, bearing cap, left end cap, pay thrust disc, bearing support, bearing shell, thrust bearing shoe valve, main thrust dish, right end cap, wherein from left to right successively by left end cap, pay thrust disc, bearing support, bearing shell, thrust bearing shoe valve, main thrust dish, right end cap is sleeved on turbine shaft, after be arranged on bearing support, it is characterized in that: the cooling chamber of bearing support, do not changing under former cooler water-cooled core size state, reduce cooler intracavity diameter, decrease the deep fat backflow space without the contact of cooler heat dissipating pipe, reflux after making deep fat must contact the cooling of cooler heat dissipating pipe, deep fat is imported and exported and is arranged on condenser chamber two ends simultaneously, and deep fat must be refluxed through cooler heat dissipating pipe whole process,
Further described modified model radial-thrust bearing, is characterized in that: right end cap seam changes and is greater than thrust disc diameter to its diameter greatly, and during maintenance, thrust disc can join generator shaft and extracts out in the lump, and dismounting is very convenient, improves work efficiency;
Further described modified model radial-thrust bearing, it is characterized in that: bearing support coordinate with thrust disc position by former open change into closed, namely former thrust disc and thrust bearing shoe valve interface lead directly to oil pocket, change thrust disc and thrust bearing shoe valve interface into just to bearing support fagging face, be more conducive to cold oil and enter radial watt, thrust bearing shoe valve working surface; Increase cold oil fuel delivery, thrust disc gets rid of oil groove to be increased, oil groove extended length; Broaden left and right end cap two road oil-return groove, favourable oil return, leaks outside to prevent fluid;
Further described modified model radial-thrust bearing, is characterized in that: bearing support condenser chamber changes through hole into by former blind hole, and two ends perforate, conveniently processes and installs.
Further described modified model radial-thrust bearing, is characterized in that: bearing cap right-hand member has set up peep hole, conveniently checks fuel feeding and operation conditions on thrust reel.
The utility model beneficial effect is: make turbine shaft and bearing attachment divide abundant cooling, extends radial watt, working life of thrust bearing shoe valve and lubricant oil; No longer because thrust disc is large and bearing (ball) cover axis hole during maintenance, make dismounting very inconvenient, reduce labor strength, improve work efficiency.
Make an explanation further with drawings and the specific embodiments below.
