1. Qhov "Fixed-Supported" Configuration Strategy
Lub hauv paus ntsiab lus tsim qauv ntawm BK/BF ua ke yog los tsim ib qho Kho -Txhawb nqa kev npaj.
- BK (Tswj):Anchors lub ntsia hlau rau lub cev muaj zog, absorbing tag nrho axial (thrust) loads.
- BF (Supported):Txhawb nqa qhov hnyav radial ntawm cov ntsia hlau tab sis tso cai rau cov ncej kom "float" axially.
Vim li cas ho tsis kho ob qhov kawg?
Thaum lub sijhawm ua haujlwm siab - nrawm, kev sib txhuam ua kom sov, ua rau lub pob hlau ntsia hlau nthuav dav (elongate). Yog tias ob qho tib si xaus tau ruaj khov, qhov kev nthuav dav thermal no yuav tsis muaj qhov twg mus, ua rau cov ntsia hlau hneev (buckle) lossis rhuav tshem cov bearings. BF chav tsev yog tsim tshwj xeeb los tso cai rau qhov kev loj hlob ntawm thermal tsis poob radial stability.
2. BK Series: Sab "Tswj" (Motor End)
BK chav tsev yog qhov tseem ceeb ntawm qhov chaw qhov tseeb. Nws sab hauv tsim yog tsom rau Axial Rigidity.
- Kev xaiv Bearing:Nyob rau hauv tus qauv BK thaiv, koj yuav tsis pom cov pob bearings txheem. Hloov chaw, nws muaj ib khub ntawm Angular Sib cuag Pob Bearings (JIS Series 70xx).
- Qhov kev npaj "DF":Ob lub bearings no yog mounted nyob rau hauv ib tug "Face-to-Face" (DF) configuration.
Vim li cas DF? Qhov kev npaj no tso cai rau lub tsev kom nqus axial thrust loads nyob rau hauv ob qho tib si kev taw qhia (thawb thiab rub). Nws kuj tseem muab tus kheej me ntsis - kho qhov muaj peev xwm los them nyiaj rau cov machining me me hauv qhov chaw mounting.
- Preload:Cov bearings yog preloaded (tightened rau ib leeg) kom tshem tawm sab hauv clearance. Qhov no ua kom ntseeg tau tias thaum lub cev muaj zog thim rov qab, muaj xoom rov qab ntawm qhov chaw txhawb nqa.
- Sealing:Cov ntsaws ruaj ruaj tshwj xeeb raug teeb tsa kom khaws lub Hoobkas - ntim lithium xab npum roj thiab tiv thaiv cov plua plav nkag.
3. BF Series: Sab "Floated" (End)
Chav tsev BF zoo ib yam li sab nraud tab sis ua haujlwm sib txawv kiag li txhua yam ua haujlwm.
Kev xaiv Bearing:Chav tsev BF feem ntau yog tsev ib leeg Deep Groove Pob Bearing (Series 60xx).
Txoj Cai Floating:
- Cov kabmob muaj kev ruaj ntseg rau cov ncej nrog lub nplhaib snap, tab sis nws tsis yog axially clamped nruj nreem nyob rau hauv lub vaj tse ib yam li BK.
- Qhov no tso cai rau cov kabmob (thiab cov ntsia hlau ncej) txav me ntsis axially raws li cov ntsia hlau heats thiab lengthens.
Load tuav:BF chav tsev tsuas yog tsim los tswj cov radial loads (txhawb qhov hnyav ntawm cov ntsia hlau thiab tiv thaiv nplawm). Nws yuav siv xoom thrust load.
4. Compact & Standardized Geometry
BK / BF series tau tsim los daws cov teeb meem ntawm kev tsim vaj tsev tsim khoom.
- Tsawg Profile:Cov duab plaub tsim tso cai rau kev txhawb nqa ncaj qha mus rau lub tshuab puag yam tsis tas yuav tsum muaj cov ncej siab.
- Siv Edges:Lub hauv paus thiab sab ntawm cov blocks yog hauv av los ua qhov chaw siv. Qhov no tso cai rau cov neeg tsim khoom siv lub ntsuas ntsuas tawm tsam sab ntawm BK thaiv kom ntseeg tau tias nws zoo sib xws rau cov kab ntawv qhia.
