Angular Sib cuag Pob Bearing

Ib kab angular hu rau pob bearings
Ib kab angular hu rau pob bearings muaj ib lub nplhaib sab nraud, ib lub nplhaib sab hauv, ib kab ntawm cov pob steel thiab lub tawb. Hom kabmob no tuaj yeem dais radial load thiab axial load tib lub sijhawm, thiab tuaj yeem dais axial load, thiab tuaj yeem ua haujlwm ntawm kev kub ceev. Ib kab angular hu rau pob bearings tsuas tuaj yeem tiv taus axial loads hauv ib qho kev taw qhia. Thaum raug rau radial loads, ntxiv axial rog yuav raug ntxias, thiab axial hloov chaw ntawm lub ncej thiab vaj tse tsuas yog txwv nyob rau hauv ib qho kev taw qhia. Txawm hais tias hom kabmob no tsuas tuaj yeem dais axial loads nyob rau hauv ib qho kev taw qhia, nws tuaj yeem ua ke nrog lwm cov kabmob uas bears loads nyob rau hauv qhov opposite direction. Yog tias nws tau nruab rau hauv khub, tib lub ntsej muag kawg ntawm lub nplhaib sab nrauv ntawm ib khub ntawm cov kabmob yog qhov sib txawv rau ib leeg, qhov kawg ntawm lub ntsej muag dav.
thiab lub ntsej muag (rov qab-rau-rov qab DB), thiab qhov kawg ntawm lub ntsej muag nqaim kawg ntawm lub ntsej muag nqaim (lub ntsej muag-rau-lub ntsej muag DF), kom tsis txhob ua rau lub zog axial ntxiv, Tsis tas li ntawd, cov ncej lossis vaj tse tuaj yeem txwv rau kev ua si axial. nyob rau hauv ob txoj kev.

Cov kab sib txuas ntawm cov kabmob ib leeg muaj ntau lub npas tshaj qhov sib sib zog nqus groove pob bearing ntawm tib qhov loj, yog li qhov ntsuas qhov hnyav yog qhov loj tshaj plaws hauv cov kabmob, qhov rigidity kuj muaj zog, thiab kev ua haujlwm ruaj khov. Lub radial clearance tuaj yeem hloov kho los ntawm kev sib nrig sib hloov ntawm lub nplhaib sab hauv thiab sab nrauv, thiab ob peb pawg ntawm cov kabmob tuaj yeem txuas nrog ua ke kom ua rau muaj kev cuam tshuam ua ntej los txhim kho lub zog ntawm lub cev.
Kev siv cov angular hu rau pob bearings tsis tuaj yeem disassembled, thiab nws tus kheej-aligning peev xwm yog heev txwv.
Cov yam ntxwv ntawm cov kabmob no yog tias lub kaum sab xis sib cuag tsis yog xoom, thiab cov qauv kev sib cuag ntawm ib kab angular hu rau pob bearings yog 15 °, 25 °, 30 °, thiab 40 °. Qhov loj ntawm lub kaum sab xis yog txiav txim siab lub zog radial thiab axial quab yuam uas cov kabmob tuaj yeem tiv taus thaum ua haujlwm. Qhov loj dua lub kaum sab xis, qhov ntau dua qhov axial load peev nws tuaj yeem tiv taus. Txawm li cas los xij, qhov me me ntawm lub kaum sab xis, qhov zoo dua rau kev sib hloov ceev.
Ib kab angular hu rau pob bearings tsis muaj qhov kev tshem tawm. Tsuas yog sib dhos angular hu rau pob bearings muaj kev tshem tawm sab hauv. Raws li cov kev xav tau ntawm kev ua haujlwm, muaj ob txoj hauv kev los muab cov kabmob sib dhos: preload (preload) thiab preclearance (preset clearance). Lub sab hauv clearance ntawm preloaded angular hu pob bearings yog xoom los yog tsis zoo. Nws feem ntau yog siv rau ntawm spindle ntawm cov cuab yeej siv tshuab los txhim kho qhov rigidity thiab kev sib hloov qhov tseeb ntawm spindle. Lub clearance (preload) ntawm cov khub angular hu rau pob bearings tau raug kho ua ntej tawm hauv lub Hoobkas, thiab tsis tas yuav tsum tau kho cov neeg siv. Lub ntsiab dav kam rau ua thiab kawg lub ntsej muag protrusion ntawm zoo tib yam ib leeg-kab angular hu rau pob bearings tsuas yog ua raws li cov qib zoo tib yam, thiab tsis tuaj yeem ua khub thiab sib xyaw ua ke ntawm qhov xav tau.
Kev tsim cov universal assembled angular contact ball bearings tuaj yeem sib sau ua ke hauv txhua txoj kev, xws li rov qab-rau-rov qab, ntsej muag-rau-lub ntsej muag lossis hauv series. Muaj ob txoj hauv kev los muab universal txuam bearings: preload (preload) thiab preclearance (preset clearance). Nrog rau kev zam ntawm universal assembled bearings, tus kheej bearings nyob rau hauv lwm yam sib dhos bearings yog interchangeable.
Ob chav kab angular hu rau pob bearings
Kev tsim ntawm ob kab angular hu rau pob bearings yog qhov yooj yim tib yam li ntawm ib kab angular hu rau pob bearings, tab sis tsuas yog siv qhov chaw axial tsawg. Ob chav kab angular hu rau pob bearings tuaj yeem tiv taus radial loads thiab axial loads ua haujlwm hauv ob qho tib si. High rigidity bearing kev npaj muaj thiab tuaj yeem tiv taus lub sijhawm dhau los.
Ib kab angular hu rau pob bearings thiab ua ke angular hu pob bearings
Txhawm rau txhim kho qhov rigidity thiab load-nqa peev xwm ntawm angular hu rau pob bearings, angular hu pob bearings ntawm tib lub specification yog feem ntau sib sau ua ke nyob rau hauv ob chav plaub (QBCQFC, QT) los yog txawm quintuple (PBC, PFC, PT, PBT, PFT) daim ntawv. Rau ob chav angular hu rau pob bearings, txoj kev npaj tau muab faib ua peb hom: rov qab-rau-rov qab (DB), lub ntsej muag-to-face (DF), thiab tandem (DT). Back-to-back angular contact ball bearings yog tsim rau cov kabmob sib cais lossis sib xyaw ua ke radial thiab axial loads, thiab tuaj yeem tiv taus ob txoj kev axial loads. Nws muaj peev xwm dais loj overturning lub sij hawm thiab muaj zog rigidity. Txawv preloads tuaj yeem siv tau raws li kev ua haujlwm. Lub ntsej muag-rau-lub ntsej muag angular hu rau pob bearings yuav raug txo qis lub sijhawm dhau los thiab muab cov txheej txheem qis dua. Qhov zoo dua yog tias nws tsis tshua muaj kev cuam tshuam rau cov kabmob vaj tsev concentricity yuam kev. Angular contact pob bearings tau teem tseg nyob rau hauv series tsuas yog tso cai rau dais axial load loj nyob rau hauv ib qho kev taw qhia. Feem ntau, lub caij nplooj ntoos hlav yog siv los thov preload, thiab tus nqi ntawm radial load uas tuaj yeem txhawb nqa thiab qhov nruj ntawm cov kabmob yog nyob ntawm tus nqi xaiv preload.
