Yuav kom tswj tau qhov tseeb hauv cov lus tsa suab, lub pob ntsia hlau yuav tsum tau muab khi thiab txhawb nqa ntawm ob qho kawg. Txawm li cas los xij, qhov ruaj khov thiab txhawb nqa xaus ua haujlwm sib txawv.
1. Qhov "Fixed-Supported" Paradigm
Tsau Sab (BK / EK / FK Qauv):Chav tsev no ua tus thawj thauj tog rau nkoj rau cov ntsia hlau, absorbing 100% ntawm axial (thrust) loads thaum tuav xoom-backlash positioning. Sab hauv, cov blocks no muaj ib khub ntawm Angular Contact Ball Bearings nyob rau hauv ib lub ntsej muag - rau -Face (DF) configuration. Qhov kev teeb tsa no yog preloaded tiv thaiv lub kaw lus precision, tsim kom muaj lub thauj tog rau nkoj nruj uas tiv thaiv kev thawb los ntawm ob qho kev qhia.
Txhawb Sab (BF / EF / FF Qauv):Chav tsev no txhawb nqa qhov hnyav radial ntawm cov ntsia hlau los tiv thaiv sagging. Nws muaj qhov sib sib zog nqus Groove Pob Bearing, qhov twg cov ncej yog ruaj khov rau hauv cov haiv neeg sab hauv, tab sis cov haiv neeg sab nrauv yog dawb los swb tom qab hauv vaj tse. Qhov "floating" tsim no tso cai rau cov ntsia hlau nthuav dav lossis cog lus vim kev sib txhuam thermal yam tsis muaj kev ntxhov siab axial, nyo hau, lossis kev coj tus kheej tsis ua haujlwm.
2. Navigating Form Factors
Cov chav txhawb nqa muaj nyob rau hauv peb qhov sib txawv geometries kom haum rau ntau lub tshuab tsim:
- BK / BF (Phillow Block):Industrial workhorse. Qhov hnyav no -lub luag haujlwm, cov duab plaub txuas ncaj qha mus rau lub phaj tiaj tiaj. Zoo tagnrho rau CNC routers thiab kev lag luam automation.
- EK / EF (Compact Block):Tsawg-profile, qhov chaw-txuag tsim. Lub mounting hneev taw yog tus qauv zoo heev los ua kom haum nrog kev sib koom ua ke stepper lub cev muaj zog, ua rau nws nyiam xaiv rau 3D tshuab luam ntawv thiab cov theem compact.
- FK / FF (Flange Mount):Features ib ncig vaj tse nrog ib tug integrated mounting flange. Cov chav no yog tsim los rau bolt ncaj qha mus rau ntsug tshuab phab ntsa lossis bulkheads, es tsis yog lub hauv paus phaj.
