1. Ingabe zikhona izidingo zendawo yokufaka nendawo yokufaka?

yebo.Uma kukhona izinto zangaphandle ezifana ne-iron filings, ama-burrs, uthuli, njll. ku-bearing, kuzodala umsindo nokudlidliza ngesikhathi sokusebenza kwe-bearing, futhi kulimaze nomgwaqo womjaho kanye nezinto eziginqikayo.Ngakho-ke, ngaphambi kokufaka i-bearing, kufanele uqinisekise ukuthi indawo yokufaka nendawo yokufaka ihlanzekile.

Okwesibili, ingabe i-bearing kufanele ihlanzwe ngaphambi kokufakwa?

I-bearing surface igcotshwe ngamafutha e-anti-rust, kufanele uyihlanze ngokucophelela ngophethiloli ohlanzekile noma uphalafini, bese usebenzisa amafutha okugcoba ahlanzekile asezingeni eliphezulu noma anesivinini esiphezulu ngaphambi kokufakwa nokusetshenziswa.Umthelela wokuhlanzeka ekuthwaleni ukuphila nomsindo wokudlidliza mkhulu kakhulu.Kodwa sithanda ukukukhumbuza ukuthi: i-bearing evalwe ngokugcwele ayidingi ukuhlanzwa nokufakwa amafutha.

Okwesithathu, indlela yokukhetha amafutha?

Ukugcoba kunethonya elibaluleke kakhulu ekusebenzeni nasekuphileni kwama-bearings.Nasi isingeniso esifushane sezimiso ezijwayelekile zokukhetha amafutha.I-grease yenziwe ngamafutha ayisisekelo, i-thickener kanye nezithasiselo.Ukusebenza kwezinhlobo ezahlukene kanye nemikhiqizo ehlukene yamafutha ohlobo olufanayo kuhluke kakhulu, futhi imikhawulo evumelekile yokujikeleza ihlukile.Qaphela lapho ukhetha.Ukusebenza kwamafutha okugcoba ikakhulukazi kunqunywa uwoyela wesisekelo.Ngokuvamile, i-low-viscosity base base oil ifanele izinga lokushisa eliphansi kanye nesivinini esikhulu, futhi i-high-viscosity base base oil ifanele izinga lokushisa eliphezulu nomthwalo ophezulu.I-thickener nayo ihlobene nokusebenza kokugcoba, futhi ukumelana kwamanzi kwe-thickener kunquma ukumelana kwamanzi kwamafutha.Eqinisweni, amafutha emikhiqizo ehlukene awakwazi ukuxutshwa, futhi ngisho namafutha ane-thickener efanayo azoba nemiphumela emibi komunye nomunye ngenxa yezithako ezahlukene.

Okwesine, lapho ugcoba ama-bearings, ingabe ukugcotshwa kwamafutha amaningi, kungcono?

Kungumbono oyiphutha ovamile ukuthi lapho ugcoba amabherethi, amafutha amaningi aba ngcono.Igrisi eyeqile egumbini elithwalayo lizodala ukunyakaza okukhulu kwamafutha, okuholela ekushiseni okuphezulu kakhulu.Kunconywa ukugcwalisa ukuthwala nge-1/2 kuya ku-1/3 yesikhala sangaphakathi sokuthwala, futhi kufanele kuncishiswe ku-1/3 ngesivinini esikhulu.

Okwesihlanu, ukufaka nokususa kanjani?

Lapho ufaka, ungasando ngokuqondile ubuso besiphetho se-bearing and surface non-stressed.Sebenzisa amabhulokhi okucindezela, imikhono noma amanye amathuluzi okufaka (amathuluzi) ukwenza i-ayirethi igcizelelwe ngokulinganayo, futhi ungafaki ngokusebenzisa amandla okudlulisa ama-elementi aginqikayo.Uma indawo yokukhweza igcotshisiwe, ukufakwa kuzoba bushelelezi.Uma ukuphazamiseka kukukhulu, ukuthwala kufanele kushiswe ku-80 ~ 90 ℃ ku-oyela wamaminerali futhi kufakwe ngokushesha ngangokunokwenzeka, futhi izinga lokushisa likawoyela kufanele lilawulwe ngokuqinile lingeqi i-100 ℃ ukuvimbela umphumela wokushisa ekunciphiseni ubulukhuni nokuthinta. alulame usayizi.Uma kwenzeka ubunzima ekuhlakazeni, kunconywa ukuthi usebenzise ithuluzi le-disassembly ukuze uthele ngokucophelela amafutha ashisayo endandeni yangaphakathi ngenkathi udonsa ngaphandle.Ukushisa kuzokwandisa indandatho yangaphakathi yokuthwala, okwenza kube lula ukuwa.

Okwesithupha, ingabe i-radial clearance ye-bearing incane ngangokunokwenzeka?

Akuwona wonke ama-bearings adinga imvume encane yokusebenza, kufanele ukhethe imvume efanele ngokuya ngemibandela.Esilinganisweni kazwelonke 4604-93, ukucaciswa kwe-radial of rolling bearings kuhlukaniswe ngamaqembu amahlanu - iqembu 2, iqembu 0, iqembu 3, iqembu 4, kanye neqembu 5. yi-standard clearance.Iqembu eliyisisekelo le-radial clearance lifanele izimo zokusebenza ezijwayelekile, izinga lokushisa elivamile kanye nokulingana kokuphazamiseka okuvame ukusetshenziswa;ama-bearings asebenza ngaphansi kwezimo ezikhethekile ezifana nokushisa okuphezulu, isivinini esikhulu, umsindo ophansi kanye nokungqubuzana okuphansi kufanele kukhethe imvume enkulu ye-radial;Ukukhishwa kwe-radial encane kufanele kukhethwe ama-spindles anembile, ama-spindle amathuluzi omshini, njll.;inani elincane lemvume yokusebenza lingagcinwa kuma-roller bearings.Ngaphezu kwalokho, akukho imvume yama-bearings ahlukene;ekugcineni, imvume yokusebenza ngemuva kokufakwa kokuthwala incane kunemvume yasekuqaleni ngaphambi kokufakwa, ngoba ukuthwala kufanele kuthwale umthwalo othile ukuze kujikeleze, futhi ukulingana okuthwala nomthwalo kukhiqizwa.inani le-deformation elastic.
