Sib sib zog nqus groove pob bearings tsis tuaj yeem dais hnyav axial loads, yog li angular hu rau pob bearings (tseem hu ua thrust bearings) feem ntau yog siv los nrhiav cov bearings hauv ntsug motors. Txawm hais tias ib leeg-kab lossis ob-kab tsim, angular hu rau pob bearings muaj siab axial load nqa peev xwm thiab kev ua haujlwm ceev. Ms. San yuav tham nrog koj txog ntsug lub cev muaj zog bearings hnub no.
Angular contact pob bearing kev faib tawm thiab siv
Angular contact pob bearings muaj nyob rau hauv 7000C (∝=15°), 7000AC (∝=25°) thiab 7000B (∝=40°). Hom kabmob no feem ntau muaj lub nplhaib sab hauv thiab sab nraud uas tsis tuaj yeem sib cais thiab tuaj yeem tiv taus cov radial thiab axial loads nrog rau cov axial loads hauv ib qho kev coj. Lub peev xwm los tiv thaiv axial loads yog txiav txim los ntawm lub kaum sab xis ntawm kev sib cuag. Qhov loj dua qhov kev sib cuag lub kaum sab xis, qhov siab dua qhov muaj peev xwm tiv taus axial loads. Hom kabmob no tuaj yeem txwv qhov kev hloov pauv ntawm axial ntawm lub ncej lossis vaj tsev nyob rau hauv ib qho kev coj.
Ib kab angular hu rau pob bearings yog tsuas yog siv nyob rau hauv lub tshuab cuab tam spindles, high-frequency motors, roj turbines, centrifugal separators, me me tsheb pem hauv ntej log, sib txawv pinion shafts, booster twj, drilling platforms, zaub mov machinery, faib lub taub hau, kho vuam tshuab. , low-noise cooling towers, electromechanical equipment, coating equipment, machine tool slots, arc welding machines, etc. Feem ntau siv bearings rau ntsug motors yog ib-kab angular hu rau pob bearings.
Ib kab angular hu rau pob bearings rau ntsug motors
Cov bearings ntsia nyob rau hauv ntsug motors muaj feem xyuam rau lub hwj chim thiab nruab nrab qhov siab ntawm lub cev muaj zog nws tus kheej. Ntsug motors H280 thiab hauv qab no feem ntau siv sib sib zog nqus groove pob bearings, thaum motors H315 thiab saum toj no siv angular hu bearings. High-precision thiab high-speed bearings feem ntau muaj lub kaum sab xis ntawm 15 degrees. Nyob rau hauv qhov kev txiav txim ntawm axial quab yuam, lub kaum sab xis ntawm kev sib cuag yuav nce.
Thaum siv angular hu rau pob bearings rau ntsug motors, lawv feem ntau ntsia ntawm qhov kawg uas tsis yog-extension kom paub meej tias cov ncej txuas ntxiv kawg cov kabmob tuaj yeem tiv taus lub zog radial. Txawm li cas los xij, muaj cov kev cai nruj heev rau kev teeb tsa ntawm lub kaum sab xis ntawm lub pob bearings, uas yuav tsum xyuas kom meej tias cov kabmob muaj peev xwm tiv taus lub zog qis qis, uas yog, raws li lub ntiajteb txawj nqus kev taw qhia ntawm lub rotor.
Cias muab, yog hais tias lub angular contact pob bearing nyob rau sab saum toj, nws yog tsim nyog los xyuas kom meej tias cov kabmob "hangs" lub rotor; Yog hais tias lub angular contact pob bearing nyob rau hauv qab, nws yog ib qho tsim nyog los xyuas kom meej tias cov kabmob tuaj yeem "txhawb" lub rotor. Txawm li cas los xij, raws li qhov ua tau raws li qhov xav tau ua haujlwm saum toj no, cov txheej txheem sib dhos ntawm lub hau kawg yuav tsum tau txiav txim siab, uas yog, lub zog sab nraud thaum lub sij hawm sib dhos ntawm lub hau kawg yuav tsum ua raws li lub zog axial uas cov kabmob tuaj yeem tiv taus ( lub axial quab yuam uas lub nplhaib puab thiab lub nplhaib sab nraud ntawm lub angular contact pob bearing tuaj yeem tiv tau nyob rau hauv cov lus qhia tawm), txwv tsis pub cov kabmob yuav raug thawb sib nrug.
Raws li cov kev cai saum toj no, thaum lub ncej ntawm lub cav ntsug yog tig mus rau sab saud, lub angular hu bearing yog ntsia rau ntawm qhov tsis-shaft extension kawg, uas tsis tsuas yog ua tau raws li lub axial quab yuam, tab sis kuj ua kom cov txheej txheem sib dhos ntawm lub hau kawg; Thaum lub ncej ntawm lub cev muaj zog yog tig mus rau hauv qab, lub angular contact bearing kuj tau teeb tsa ntawm qhov tsis-ncej txuas ntxiv kawg, tab sis cov kev ntsuas sib xws yuav tsum tau ua thaum sib dhos lub hau kawg kom paub meej tias cov kabmob tsis puas.
