Kuyini ukuvuleka futhi ukuvuleka kukalwa kanjani kwama-rolling bearings?

Ukuhlukaniswa kwe-rolling bearing yinani elikhulu lomsebenzi elibamba indandatho eyodwa endaweni yayo kanti enye ibambe i-radial noma i-axial direction. Umsebenzi omkhulu ohlangothini lwe-radial ubizwa ngokuthi i-radial clearance, kanti umsebenzi omkhulu ohlangothini lwe-axial ubizwa ngokuthi i-axial clearance. Ngokuvamile, lapho i-radial clearance inkulu, i-axial clearance inkulu, futhi okuphambene nalokho. Ngokusho kwesimo se-bearing, i-clearance ingahlukaniswa ngezinhlobo ezintathu ezilandelayo:

I. Imvume yokuqala

Ukususwa kwamahhala ngaphambi kokufakwa kwamabhereyi. Ukususwa kwasekuqaleni kunqunywa ukucutshungulwa nokuhlanganiswa komenzi.

2. Faka indawo yokuvula

Eyaziwa nangokuthi i-fit clearance, i-clearance lapho i-bearing kanye ne-shaft kanye ne-bearing housing sekufakiwe kodwa kungakasebenzi. I-mounting clearance incane kune-clearance yokuqala ngenxa yokuphazamiseka kokufakwa, kungaba ukwandisa indandatho yangaphakathi, ukunciphisa indandatho yangaphandle, noma kokubili.

3. Imvume yokusebenza

Uma ibhereyi isesimweni sokusebenza, izinga lokushisa lendandatho yangaphakathi liyakhuphuka liye phezulu kanye nokwanda kokushisa kuye phezulu, ukuze i-bearing clearance yehle. Ngesikhathi esifanayo, ngenxa yomphumela womthwalo, ukuguquguquka kwe-elastic kwenzeka endaweni yokuxhumana phakathi komzimba ogoqekayo kanye nomgwaqo wokugijima, okwandisa i-bearing clearance. Ukuthi i-bearing clearance yokusebenza inkulu noma incane kune-mounting clearance kuncike emphumeleni ohlangene walezi zici ezimbili.

Amanye ama-rolling bearings awakwazi ukulungiswa noma ukuhlukaniswa. Atholakala ngamamodeli ayisithupha, kusukela ku-0000 kuya ku-5000; Kukhona uhlobo 6000 (ama-angular contact bearings) kanye nohlobo 1000, Uhlobo 2000 kanye nohlobo 3000 olunezimbobo zekhoni eringini yangaphakathi. Indawo yokufaka yalezi zinhlobo zama-rolling bearings, ngemva kokulungiswa, izoba yincane kunendawo yokuqala. Ngaphezu kwalokho, amanye ama-bearings angasuswa, futhi indawo yokugcina ingalungiswa. Kunezinhlobo ezintathu zama-bearings: Uhlobo 7000 (i-tapered roller bearing), uhlobo 8000 (i-thrust ball bearing) kanye nohlobo 9000 (i-thrust roller bearing). Akukho ndawo yokuqala kulezi zinhlobo ezintathu zama-bearings. Kuma-rolling bearings ohlobo 6000 kanye nohlobo 7000, indawo yokugcina i-radial iyancipha kanti indawo yokugcina i-axial nayo iyancipha, futhi okuphambene nalokho, kuyilapho kuma-rolling bearings ohlobo 8000 kanye nohlobo 9000, indawo yokugcina i-axial kuphela ebaluleke kakhulu.

Indawo efanele yokufaka ivumela ukusebenza okuvamile kwebheri eligoqayo. Indawo incane kakhulu, izinga lokushisa lebheri eligoqayo liyakhuphuka, alikwazi ukusebenza kahle, okwenza umzimba ogoqayo ubambeke; Indawo evulekile kakhulu, ukudlidliza kwemishini, umsindo webheri eligoqayo.

Indlela yokuhlola i-radial clearance yile elandelayo:

I. Indlela yokuzwa

1. Ngebheri ejikelezayo ngesandla, ibheri kufanele ibe bushelelezi futhi iguquguquke ngaphandle kokunamathela kanye nokungazwani.

2. Shukumisa indandatho yangaphandle yebheri ngesandla. Ngisho noma isikhala se-radial singama-0.01mm kuphela, ukunyakaza kwe-axial kwephuzu eliphezulu lebheri kungu-0.10-0.15mm. Le ndlela isetshenziselwa amabheri ebhola eliphakathi nendawo elilodwa.

Indlela yokulinganisa

1. Hlola futhi uqinisekise isikhundla esiphezulu somthwalo we-rolling bearing nge-feeler, faka i-feeler phakathi komzimba ogoqayo ongu-180° kanye nendandatho yangaphandle (yangaphakathi), futhi ubukhulu obufanele be-feeler buyi-radial clearance ye-bearing. Le ndlela isetshenziswa kabanzi kuma-self-aligning bearing kanye nama-cylindrical roller bearing.

2, hlola ngesibonakaliso sokudayela, qala usethe isibonakaliso sokudayela sibe yi-zero, bese uphakamisa indandatho yangaphandle yebhere eligoqekayo, ukufundwa kwesibonakaliso sokudayela kuwukucaca kwe-radial kwebhere.

Indlela yokuhlola ye-axial clearance yile elandelayo:

1. Indlela yokuzwa

Hlola i-axial clearance ye-rolling bearing ngomunwe wakho. Le ndlela kufanele isetshenziswe lapho ukuphela kwe-shaft kuveziwe. Uma ukuphela kwe-shaft kuvaliwe noma kungenakuhlolwa ngeminwe ngezinye izizathu, hlola ukuthi i-shaft iyaguquguquka yini ekujikelezeni.

2. Indlela yokulinganisa

(1) Hlola nge-feeler. Indlela yokusebenza iyafana naleyo yokuhlola i-radial clearance nge-feeler, kodwa i-axial clearance kufanele ibe

C = i-lambda/isono (i-beta engu-2)

Lapho c -- ukucaciswa kwe-axial, mm;

-- Ubukhulu begeyiji, mm;

-- I-engela yekhoni yokuthwala, (°).

(2) Hlola ngesibonakaliso sokudayela. Uma i-crowbar isetshenziswa ukuhambisa umgodi ohambayo uye ezindaweni ezimbili ezibucayi, umehluko wokufundwa kwesibonakaliso sokudayela yi-axial clearance yebhereyi. Kodwa-ke, amandla asetshenziswa ku-crowbar akufanele abe makhulu kakhulu, ngaphandle kwalokho igobolondo lizoba nokuguquguquka okunwebekayo, noma ngabe ukuguqulwa kuncane kakhulu, kuzothinta ukunemba kwe-axial clearance elinganisiwe.
