Waa maxay warshadaha codsiga ee noocyada gaarka ah ee xeedhada?
Bearings-ka moodooyinka kala duwan ayaa si weyn loogu isticmaalaa qaybaha warshadaha kala duwan sababtoo ah astaamaha qaab-dhismeedkooda iyo kala duwanaanshaha waxqabadka. Sharax xaaladaha codsigooda caadiga ah iyadoo lagu darayo kala-soocidda moodeelka:
- god qoto dheer Kubbadaha Kubadda
- moodooyinka yaryar (sida 606):
Bundle-yada qalabka guriga, rotor-yada matoorada yaryar, qalabka saxda ah .
- Taxanaha caadiga ah (sida 6000, 6002):
Matoor baabuur, bamka biyaha, qalabka korontada (qol koronto, mishiinka shiididda xagasha).
- moodooyinka faraantiga gudaha ee ballaaran (sida 6204, 6304):
Taageerayaasha warshadaha, suunka gudbiyaha roogagas, sanduuqyada gearbox-ka ee mashiinnada beeraha.
- Biirta duuban ee la duubay
- Moodooyin yaryar iyo kuwa dhexdhexaadka ah (sida 30205):
Giraangiraha baabuurta, geerka gudbinta, iyo ul-wareegyada qalabka mashiinka.
- cabbirrada waaweyn (sida 30310):
Mashiinnada dhismaha (taayirrada raadadka qoda), usha ugu weyn ee burburiyaha macdanta, kala duwanaanshaha baabuurta culus.
3. Biiriyeyaasha duubista siligga ah (taxanaha NN/NU)
- NN3020K (tiir laba jibbaaran):
Lug-lugeedka qalabka mashiinka, rotor-ka matoorka xawaaraha sare leh, qoorta duubista saxda ah ee .
- Taxanaha NOW:
Taageero weyn oo ah stator-ka matoorka, sanduuqa axalka gaadiidka tareenka .
Xeerarka aasaasiga ah ee qaybinta warshadaha:
1. Warshadaha baabuurta (oo ka kooban 43%)
Biiriyeyaasha Hub (biiriyeyaasha duuban ee wareegsan), biiriyeyaasha matoorka (biiriyeyaasha kubbadda jeexdinta qoto dheer), biiriyeyaasha gearbox (biiriyeyaasha kubbadda taabashada xagasha)
2. Tamarta iyo warshadaha culus
Usha ugu weyn ee marawaxadaha dabaysha (boodhadhka duubista is-waafajinta), cutubka korontada kulaylka (boodhadhka duubista silindrical)
3. Qalabka heerka sare ah
Usha ugu weyn ee matoorka diyaaradaha (boodhadhka kubbadda dhoobada ah), sanduuqa sanduuqa tareenka xawaaraha sare leh (boodhadhka saxda ah ee xawaaraha sare leh).
Talada xulashada: Bearings-ka isku qaabka ah ayaa lagu dabaqi karaa xaalado kala duwan sababtoo ah darajooyinkooda saxda ah (P5/P4). Tusaale ahaan, bearings-ka qalabka mashiinka waxay u baahan yihiin bearings-ka saxda ah ee heerka P4 ama ka sareeya . Bearings-ka awoodda dabaysha waxay u baahan yihiin naqshad gaar ah oo ka hortagga daxalka iyo cimriga adeegga . Wixii cabbirro gaar ah oo ku saabsan moodeelka, fadlan tixraac buug-gacmeedka farsamada ee soo saaraha.
Shuruudaha aasaasiga ah ee waxqabadka raritaanka si weyn ayay ugu kala duwan yihiin warshadaha kala duwan, inta badan waxay diiradda saaraan cabbirrada sida saxnaanta, xawaaraha wareegga, awoodda rarka, iyo la qabsiga deegaanka.
Warshadaha baabuurta
1. Biirta cusub ee matoorka wadista tamarta: Waxaa looga baahan yahay inay lahaadaan xawaare ugu badan (qiimaha dm•n ≥ 70,000 mm·r/daqiiqo), iska caabin heerkul sare (> 150℃), iyo iska caabin gariir oo soo noqnoqota. Agabku wuxuu u baahan yahay inuu lahaado xasillooni sare, nidaamka saliidayntana wuxuu u baahan yahay inuu la qabsado xaaladaha shaqada ee adag ee matoorka .
1. Biirayaasha matoorka ee dhaqanka: Biirayaasha jiidista iyo kuwa jiidista ee aan shaqaynayn waxay u baahan yihiin inay yeeshaan adkeysi sare iyo buuq yar si ay u daboolaan shuruudaha gudbinta hufan ee isbeddelka ilaalinta tamarta matoorka.
- Bearing-ka Hub: Bearing-yada rogo ee wareegsan waxay u baahan yihiin inay u adkeystaan culeyska saameynta laba geesoodka ah iyagoo buuxinaya shuruudaha naqshadeynta fudud iyo cimriga dheer (sida in ka badan 1 milyan oo kiiloomitir).
Hawada Sare
1. Xadka saxda ah: Dulqaadka biinanka matoorka hawada waa inuu ahaadaa ≤0.005 milimitir (5 microns), moodooyinka militariguna xitaa waxay u baahan yihiin saxnaan 0.1 microns.
- Dulqaad xad dhaaf ah oo deegaan:
- Biirta booska waa inay u adkaysataa heerkulka sare iyo kan hoose (-180℃ ilaa 300℃), shucaaca, isla markaana ay leedahay hoos u dhac gaas.
- Xalli dhibaatada saliidaynta faakuumka adigoo isticmaalaya walxaha dhoobada ah ama saliidaha perfluoropolyether (PFPE).
- Kalsoonida: Suurtagalnimada guuldarada 20,000 wareeg daqiiqaddii).
Tamarta iyo Warshadaha Culus
1. Marawaxadaha dabaysha ee usha ugu weyn:
Biiriyeyaasha is-waafajinta ee is-waafajiya waxay u baahan yihiin inay u adkeystaan isbeddelka culeyska dabaysha ee xooggan iyo daqiiqadaha leexashada, dahaarka ka hortagga daxalkana waa in loogu talagalay deegaannada buufinta milixda.
Cimriga naqshadaynta > 20 sano, wareegga dayactirka ≥5 sano .
2. Qalabka korontada/korontada biyaha:
Biirta wareega ee silindrical-ka ah waxay siddaa culaysyo radial ah oo boqolaal tan ah waxaana loo isticmaalaa iyadoo lala kaashanayo nidaamka qaboojinta dibadda si loo xakameeyo kor u kaca heerkulka.
Darajooyinka birta gaarka ah (sida birta M50) ayaa loo xushay aagagga heerkulka sare leh .
