Description
Technical field
The utility model is a kind of water lubrication two-way working thrust bearing device.
Background technique
The self oiling bearing of water lubricating thrust bearing to be a kind of with water be medium, namely be that oiling agent (water) to be brought between thrust bearing shoe valve and thrust collar and to produce hydrodynamic lubrication moisture film by the thrust collar rotated when bearing runs, thrust bearing shoe valve generally adopts carbon, graphite or the composite material with self-lubricating function to make.In order to reduce the frictional force between thrust collar and thrust bearing shoe valve, the roughness requirements of thrust collar is very high, and needs higher hardness to meet wear-resistant needs.
The third generation large-scale advanced pressurized water reactor nuclear power shielding motor-drive pump is one of nucleus equipment of key in reactor-loop system.Because the direct upset hanging of shielding motor-drive pump is in steam generator lower end, without supporting separately, shielding motor-drive pump rotor is immersed in transported flowing medium high speed and rotates, and the rotor of rotation will produce powerful thrust, and this thrust needs a thrust-bearing to bear.Because rotor weighs tens tons, and the thrust that canned motorpump impeller produces has reached tens tons, comprehensive thrust can reach more than 30 ton, adopt traditional one-way only operation thrust-bearing inevitably to produce thrust vectoring to impact, this impact probably destroys the part of thrust-bearing, causes bearing fault.
In order to solve the thrust vectoring shock problem that this rotor produces, new thrust-bearing adopts the mode of spring pre-tightening to be linked together closely with thrust collar by thrust pad watt, when thrust collar moves up and down with rotor axial power effect generation, spring produces immediately and follows interlock, bearing is run level and smooth, without rigid percussion.
Summary of the invention:
The purpose of this utility model is the water lubrication two-way working thrust bearing device that a kind of satisfied shielding motor-drive pump of design adopts, and making it when meeting canned motorpump stable operation, reducing as far as possible or not producing the new bearing structure device that thrust vectoring causes impact.The technical solution of the utility model is: a kind of water lubrication two-way working thrust bearing device, bearing support (1) is upper and lower symplex structure, wherein preloading spring (2) is arranged in the spring chamber of bearing support (1), and preloading spring (2) is fitted on track plates (3); Lower equilibrium block (4) and upper equilibrium block (6) are circumferentially connected into a loop configuration by roller (5) and are stacked on track plates (3) vertically; Thrust bearing shoe valve (8) is embedded on thrust bearing segment base (7); Thrust bearing segment base (7) is arranged on equilibrium block (6), and side adopts locating stud (9) and bearing support (1) to carry out spacing; Thrust collar (10) is arranged in the middle of bearing support (1), gap is provided with between bearing support (1) and track plates (3), a sleeve (12) is set between bearing support (1), motor bottom (14) is upper and bearing support (1), sleeve (12) are pressed to the bearing chamber of support (11) being tightened to electric machine stand (11) by bolt (13), and the gap between bearing support (1), track plates (3) can be adjusted by the axial length of sleeve (12).
Doubledirection thrust bearing of the present utility model is vertical structure, the utility model is that the thrust-bearing new structure that a pair is connected by equilibrium block is arranged on thrust collar two ends, and by preloading spring, thrust bearing shoe valve is pressed on thrust collar, work under making bearing thrust head two ends be in the load of design needs all the time.The utility model doubledirection thrust bearing is arranged in the support bearing chamber of canned motorpump motor, arranges a regulating sleeve between upper lower thrust-bearing, and bottom by bottom compression axis bearing, and compresses being incorporated on support with bolt.During bearing working, thrust collar is run by the gap of the spring constraint of two ends pretension between track plates and bearing support all the time, reaches the designing requirement of two-way working.
Advantage of the present utility model: thrust bearing shoe valve is pressed on thrust collar by two ends preloading spring by thrust-bearing, the thrust load produced when thrust collar runs is impacted and is absorbed by preloading spring, thus plays protecting against shock ability.Upper and lower equilibrium block is connected into loop configuration by the roller installed between which, when being wherein arranged on the thrust bearing shoe valve surface on upper equilibrium block and exceeding adjacent counterweights, first thrust collar is pressed in higher forces watt, this thrust bearing shoe valve drives lower equilibrium block to be delivered to adjacent upper equilibrium block by the upper equilibrium block that its lower end supports, thus the thrust bearing shoe valve end of compared with that jack-up is adjacent, to reach the new structure making thrust bearing shoe valve mutually balance.

Embodiment
A water lubrication two-way working thrust bearing device as shown in Figure 1, bearing support 1 is upper and lower symplex structure, and wherein preloading spring 2 is arranged in the spring chamber of bearing support 1, and preloading spring 2 is fitted on track plates 3; As shown in Figure 2, lower equilibrium block 4 and upper equilibrium block 6 are circumferentially connected into a loop configuration by roller 5 and are stacked on track plates 3 vertically; As shown in Figure 4, thrust bearing shoe valve 8 is embedded on thrust bearing segment base 7; Thrust bearing segment base 7 is arranged on equilibrium block 6, side adopts locating stud 9 and bearing support 1 to carry out spacing; Thrust collar 10 is arranged in the middle of bearing support 1, gap is provided with between bearing support 1 and track plates 3, a sleeve 12 is set between bearing support 1, motor bottom 14 is by bolt 13 to be tightened on electric machine stand 11 and bearing support 1, sleeve 12 to be pressed to the bearing chamber of support 11, and the gap between bearing support 1, track plates 3 can be adjusted by the axial length of sleeve 12.
As shown in Figure 3, doubledirection thrust bearing is installed in electric machine stand 11 bearing chamber, a sleeve 12 is set between the bearing support 1 of upper and lower doubledirection thrust bearing to regulate the axial clearance of bearing, motor bottom 14 is tightened on electric machine stand 11 by bolt 13 handle, and bearing support 1, sleeve 12 are pressed to support 11 bearing chamber.Gap between bearing support 1, track plates 3 can be adjusted by the axial length of sleeve 12, and namely this gap, place is the play that bearing is commonly called as, thus forms the bidirectional propulsion structure that can follow.
Bearing support of the present utility model is the basis supporting whole bearing load, in order to the installing space that reduces spring, at bearing, it has processed the chamber of mounting spring, restraining spring circumferential movement simultaneously, meet the needs of installing space.In the design of the gap (play) of bearing between spring and track ring flat-plate.During bearing working, when thrust collar active force upwards and when being greater than the prefastening load of spring, upper end spring all compresses by thrust, at this moment upper end spring is equivalent to "Off" state, and lower end thrust bearing shoe valve only works under the prefastening load of spring.When bearing starts, lower end spring all compresses by thrust mainly gravitate, and upper end thrust bearing shoe valve only works under the prefastening load of spring.Along with the increase of thrust collar speed, axle system ties up in preset clearance to lifting force increase axle and moves, and spring is followed under pretightening force effect.Upper and lower equilibrium block is linked together by roller, when thrust pad watt unbalance stress or foozle, this deviation is tilted to regulate by equilibrium block, to ensure that every block thrust pad watt all closely contacts with thrust collar, thus achieves the new thrust bearing of shock-resistant two-way working.
