Yuav soj ntsuam Pneumatic Roofbolters bearings tom qab kev teeb tsa?

I. Kev soj ntsuam qhov tshwm sim thiab txoj haujlwm
Tom qab kev teeb tsa, ua qhov kev tshuaj ntsuam xyuas ua ntej yam tsis muaj kev cuam tshuam lub tshuab:

1. Tshawb xyuas seb lub ntsej muag kawg ntawm lub ntsej muag yog dej ntws tawm tag nrog lub xub pwg nyom, paub meej tias cov kabmob raug teeb tsa kom raug yam tsis muaj qhov khoob. Kev sim ceev tuaj yeem ua tiav siv txoj kev teeb pom kev zoo: ci lub teeb ntawm qhov sib koom ua ke ntawm cov kabmob thiab lub xub pwg nyom. Yog tias tsis muaj lub teeb pom kev, qhov haum tau txais; yog tias muaj teeb pom kev zoo sib xws, cov kabmob tsis nruj tiv thaiv lub xub pwg nyom thiab yuav tsum tau rov ua dua - nruj.

2. Saib xyuas seb lub sealing ntaus ntawv thiab axial fastening ntaus ntawv raug ntsia kom raug, paub meej tias txoj kev roj lubrication tsis thaiv thiab cov roj lubricating tuaj yeem ntws mus rau hauv cov kabmob.

3. Tshawb xyuas kev cuam tshuam lossis rub tawm ntawm qhov txav mus los thiab chaw nyob ruaj khov, paub meej tias tsis muaj qhov cuam tshuam ntawm qhov chaw thaum lub sijhawm tig.

II. Kev soj ntsuam kev sib hloov
Maj mam tig cov kabmob / spindle ntawm tes, txiav txim los ntawm ob lub ntsiab lus tseem ceeb:

1. Puas yog qhov kev sib hloov yog du thiab yoog raws, tsis muaj kev cuam tshuam, cuam tshuam, lossis tsis muaj suab nrov lossis kev co?

2. Puas yog lub spindle tsis wobble ho los ntawm ib sab mus rau sab, thiab yog rotated nrog uniform quab yuam, qhia tau hais tias lub bearing installation txoj hauj lwm yog ib txwm.

III. Radial Clearance Inspection Tsuas yog ua ntej - cuam tshuam - haum bearings, tag nrho cov pneumatic thauj tog rau nkoj drilling rig bearings yuav tsum tau kuaj radial clearance. Txoj kev tshuaj xyuas txawv rau txawv bearings:

1. Sib sib zog nqus Groove Pob Bearings / Thrust Pob Bearings: Tshawb xyuas los ntawm tes tig. Smooth, saj zawg zog rotation yam tsis muaj kev vibration los yog tseem ceeb lateral sway yog txais, ua raws li phau ntawv kev sib hloov tus qauv.

2. Cylindrical Cov Menyuam / Tus Kheej-Txhim Kho Cov Menyuam Bearings: Siv lub ntsuas ntsuas ntsuas. Ntxig lub ntsuas ntsuas ntawm cov menyuam thiab cov kabmob sib tw, nrog rau qhov tob tob tshaj li ib nrab ntawm cov menyuam ntev. Ib qho kev ntsuas ua raws li tus thawj chaw tsim khoom tus qauv tshem tawm tau txais.

3. Yog tias qhov kev tshem tawm tsis tuaj yeem lees txais: Kho cov kabmob (angular contact ball, tapered roller) tuaj yeem kho lawv qhov kev tshem tawm ncaj qha. Rau cov uas tsis yog - adjustable bearings, yog hais tias qhov clearance yog me me heev, nws qhia tau hais tias ib tug misfit los yog sib dhos yuam kev, yuav tsum tau disassembly thiab reinstallation. Kev tshem tawm ntau dhau kuj yuav tsum tau hloov lossis hloov kho.

IV. Tightness Verification Inspection Rau bearings nrog nruj - haum cuam tshuam haum, qhov nruj ntawm cov kabmob puab nplhaib thiab lub xub pwg nyom yuav tsum raug txheeb xyuas. Dhau li ntawm qhov ntsuas lub teeb, siv lub ntsuas ntsuas qhov xav tau: Siv lub ntsuas ntsuas 0.03mm tuab los ntsuas qhov nruj raws li tag nrho cov ncig ntawm cov kabmob puab lub nplhaib kawg lub ntsej muag. Yog tias nws tsis tuaj yeem muab tso rau ntawm txhua txoj haujlwm, qhov haum tau txais; yog tias nws tuaj yeem tso rau ntawm qee txoj haujlwm, lub installation yog tilted thiab yuav tsum tau kho; Yog hais tias nws tuaj yeem muab tso tau sib npaug thoob plaws, cov kabmob tsis raug ntsia tau zoo thiab yuav tsum tau thov kom nruj nws tiv thaiv lub xub pwg nyom.

V. Thrust Bearing Specific Inspection Pneumatic thauj tog rau nkoj drilling rigs feem ntau siv tiaj tus thrust bearings, uas yuav tsum tau ntxiv perpendicularity kuaj: Kho ib tug dial taw tes rau lub kawg lub ntsej muag ntawm lub tsev, nrog rau qhov taw qhia tawm tsam cov kabmob raceway. Maj mam tig lub bearing thiab saib lub dial pointer pointer. Yog hais tias tus pointer tsis deflect, lub raceway thiab ncej centerline yog perpendicular, thiab lub installation yog tsim nyog; Yog hais tias tus pointer deflects, nws tsis yog perpendicular thiab xav tau kev hloov kho.

Tom qab tag nrho cov kev soj ntsuam dhau lawm, tsis muaj -Load test run tuaj yeem ua tau rau 3-5 feeb. Yog tias tsis pom qhov kub thiab txias nce lossis suab nrov txawv txav, kev siv ib txwm ua tau.
