Bearings yog ib feem ntawm ib qho kev sib tw rolling bearing nrog ib lossis ob peb txoj kev sib tw. Taag kawg bearings siv radial bearings muaj peev xwm nqa tau ua ke (radial thiab axial) loads. Cov bearings muaj xws li: sib sib zog nqus groove pob bearings, ob kab los yog khub ib kab angular hu rau pob bearings, self-aligning pob bearings, spherical roller bearings, matched tapered menyuam bearings, NUP hom cylindrical menyuam bearings los yog nrog HJ lub kaum sab xis NJ hom cylindrical cov menyuam bearings .
Tsis tas li ntawd, kev npaj cov kabmob ntawm qhov kawg tuaj yeem muaj kev sib xyaw ntawm ob lub kabmob:
1. Radial bearings uas tsuas muaj peev xwm dais radial loads, xws li cylindrical roller bearings nrog ib lub nplhaib tsis muaj tav.
2. Bearings uas muab axial positioning, xws li sib sib zog nqus groove pob bearings, plaub-point contact pob bearings los yog bidirectional thrust bearings.
Bearings siv rau axial positioning yuav tsum tsis txhob siv rau radial positioning, thiab feem ntau muaj ib tug me me radial clearance thaum ntsia ntawm lub rooj zaum bearing.
Cov tuam txhab lag luam ceeb toom: Muaj ob txoj hauv kev los ua kom haum rau cov thermal hloov ntawm cov kabmob ntab ntab. Thawj qhov uas yuav tsum tau ua yog siv cov kabmob uas tsuas yog lees txais radial loads thiab tso cai rau kev hloov pauv axial tshwm sim hauv cov kabmob. Cov kabmob no muaj xws li: CARB toroidal cov menyuam bearings, koob rau cov menyuam bearings thiab ib tug cylindrical menyuam bearing tsis muaj tav. Lwm txoj hauv kev yog siv cov kabmob radial nrog ib qho me me radial clearance thaum mounted ntawm lub tsev kom lub nplhaib sab nraud tuaj yeem txav tau yooj yim axially.
1. Xauv txiv ntoo txoj hauv kev:
Thaum lub nplhaib sab hauv ntawm cov kabmob uas muaj kev cuam tshuam haum raug teeb tsa, ib sab ntawm lub nplhaib puab feem ntau yog muab tso rau ntawm lub xub pwg nyom ntawm tus ncej, thiab sab nraud feem ntau yog kho nrog lub ntsuas phoo (KMT lossis KMTA series). Bearings nrog tapered bores yog mounted ncaj qha rau tapered cov ntaub ntawv, feem ntau ruaj rau lub ncej nrog ib tug locknut.
2. Spacer positioning method:
Nws yog qhov yooj yim los siv spacers lossis spacers nruab nrab ntawm cov kabmob rings lossis nruab nrab ntawm cov kabmob thiab cov khoom nyob ib sab, es tsis txhob siv cov ncej lossis lub xub pwg nyom. Nyob rau hauv cov ntaub ntawv no, qhov ntev thiab daim ntawv tolerances kuj siv rau ib feem.
3. Positioning ntawm stepped bushing:
Lwm txoj kev ntawm bearing axial positioning yog siv stepped bushings. Qhov zoo tshaj plaws rau kev tswj hwm kev coj tus kheej, cov bushings no muaj tsawg dua thiab muaj qhov tseeb dua li cov xov locknuts. Stepped bushings feem ntau yog siv nyob rau hauv high-speed spindles rau cov pa locking pab kiag li lawm tsis muaj txaus txaus.
4. Tsau kawg cap positioning txoj kev:
Thaum lub Wafangdian bearing ntsia nrog ib qho kev cuam tshuam haum bearing lub nplhaib sab nraud, feem ntau yog ib sab ntawm lub nplhaib sab nraud yog tiv thaiv lub xub pwg ntawm lub rooj zaum bearing, thiab sab nraud yog tsau nrog lub hau kawg. Lub hau kawg ruaj khov thiab nws cov ntsia hlau teeb tsis zoo cuam tshuam rau kev coj tus kheej thiab kev ua haujlwm hauv qee kis. Yog hais tias cov phab ntsa thickness ntawm lub vaj tse thiab cov ntsia hlau qhov me me dhau, los yog yog hais tias cov screws yog nruj nruj heev, lub nplhaib sab nrauv raceway yuav deformed. Lub teeb ISO loj tshaj plaws series, series 19, muaj kev cuam tshuam rau hom kev puas tsuaj ntau dua li series 10 lossis hnyav dua.
