Uma kukhulunywa ngezinhlobo zama-bearings, wonke umuntu angasho ukuthi yiziphi izinhlobo zama-bearings ezisetshenziselwa?Namuhla, ake sikuthathe ukwazi izici zama-bearings ahlukahlukene kanye nezinkambu zabo zokufaka isicelo.
Ama-bearings ahlukaniswe abe ama-radial bearings kanye nama-thrust bearings ngokuya ngesiqondiso sokuthwala noma i-angle yokuxhumana okuzisholo.
Ngokusho kohlobo lwe-element rolling, ihlukaniswe ibe yi-ball bear kanye ne-roller bear.
Ingahlukaniswa ibe yi-self-aligning bearing kanye ne-non self-aligning bearing (i-rigid bear) ngokuya ngokuthi ingaba iyaziqondanisa yini.
Ngokuya ngenani lamakholomu wento egoqayo, ihlukaniswe yaba ukubethela komugqa owodwa, ukubethela kwemigqa ekabili kanye nokuveza imigqa eminingi.
Ngokuya ngokuthi izingxenye zingahlukaniswa yini, zihlukaniswe zibe ama-bearings ahlukene kanye nama-bearings angahlukaniseki.
Ngaphezu kwalokho, kunezigaba ngokuya ngokuma kwesakhiwo nosayizi.
1. Ibhola lokuxhumana eliyi-angular
Kukhona ama-engeli okuxhumana phakathi kwe-ferrule nebhola.Ama-engeli okuxhumana ajwayelekile ngu-15 °, 30 ° no-40 °.Uma i-engeli yokuxhumana inkulu, umthamo womthwalo we-axial mkhulu.Uma i-engeli yokuxhumana ibancane, iba ngcono kakhulu ekujikelezeni kwesivinini esikhulu.Ukuthwala komugqa owodwa kungamelana nomthwalo we-radial kanye nomthwalo we-axial unidirectional.Amabhola amabili omugqa owodwa angama-angular amabhola, ahlanganiswe ngokwesakhiwo ngemuva, abelane ngendandatho yangaphakathi nendandatho yangaphandle, futhi angakwazi ukumelana nomthwalo we-radial kanye nomthwalo we-axial okabili.
Ibhola lokuxhumana eliyi-angular
Injongo eyinhloko:
Umugqa owodwa: ithuluzi lokuphotha lomshini, i-high-frequency motor, i-gas turbine, isihlukanisi esiyi-centrifugal, isondo lemoto encane yangaphambili, i-pinion shaft ehlukile.
Umugqa ophindwe kabili: iphampu kawoyela, i-root blower, i-compressor yomoya, ukuhanjiswa okuhlukahlukene, iphampu yomjovo kaphethiloli, imishini yokuphrinta.
2. Ukuziqondanisa ngokwakho ibhola eliphethe
Amabhola ensimbi anomugqa okabili, umzila womjaho wendandatho yangaphandle ungowohlobo lwangaphakathi oluyindilinga, ngakho-ke ingakwazi ukulungisa ngokuzenzakalela ukungaboni ngasolinye kwe-eksisi okubangelwa ukuchezuka noma ukungagxili kwe-shaft noma indlu.I-tapered hole bearing ingafakwa kalula ku-shaft ngokusebenzisa izinsimbi, ikakhulukazi ezithwala umthwalo we-radial.
Ukuthwala ibhola
Ukusetshenziswa okuyinhloko: imishini yokwenza ukhuni, umshini wokuhambisa umshini wendwangu, i-self-aligning beararing enesihlalo.
3. Ukuziqondanisa ngokwakho i-roller bearing
Lolu hlobo lokuthwala lufakwe amarola ayindilinga phakathi kweringi yangaphandle yomjaho oyindilinga kanye nendandatho yangaphakathi yomjaho ophindwe kabili.Ngokwezinhlaka ezihlukene zangaphakathi, ihlukaniswe yaba izinhlobo ezine: i-R, i-Rh, i-RHA ne-Sr. ngoba isikhungo se-arc somzila womjaho wangaphandle siyahambisana nesikhungo sokuthwala, sinokusebenza okuphakathi, ngakho-ke ingakwazi ukulungisa ngokuzenzakalelayo ukungahambi kahle kwe-axis okubangelwa ukuchezuka noma ukungahambi kahle kwe-shaft noma igobolondo langaphandle, futhi ingathwala umthwalo we-radial kanye nomthwalo we-axial we-bidirectional
I-Spherical Roller Bearings
Izinhlelo zokusebenza eziyinhloko: imishini yephepha, i-reducer, i-axle yemoto yesitimela, isihlalo se-rolling mill roller, i-crusher, isikrini esidlidlizayo, imishini yokunyathelisa, imishini yokwenza ukhuni, izinciphisi ezihlukahlukene zezimboni, i-self-aligning bear bear nesihlalo.
4. I-Trust self-aligning roller bear
Kulolu hlobo lokuthwala, ama-rollers ayindilinga ahlelwe ngokugobile.Ngenxa yokuthi indawo yomjaho yomjaho iyindilinga futhi inokusebenza okumaphakathi, i-shaft ingavunyelwa ukuthi ibe nokuthambekela okuningana.Umthamo womthwalo we-axial mkhulu kakhulu.Ingakwazi ukuthwala imithwalo eminingi ye-radial ngenkathi ithwele umthwalo we-axial.Ukugcoba uwoyela kuvame ukusetshenziswa ngesikhathi sokusetshenziswa.
i-thrust self-aligning roller bear
Izinhlelo zokusebenza eziyinhloko: i-hydraulic generator, i-motor mpo, i-propeller shaft yemikhumbi, isinciphisi sokugoqa isikulufu sokugaya insimbi, i-tower crane, i-coal mill, i-extruder kanye nomshini wokwakha.
5. I-roller ene-tapered
Lolu hlobo lokuthwala lufakwe i-roller ene-cone, eqondiswa i-flange enkulu yendandatho yangaphakathi.Ekwakhiweni, i-apex yendawo yomjaho wendandatho engaphakathi, indawo yomjaho eyindandatho yangaphandle kanye nezindawo eziyikhothane zendawo eginqikayo ziyaphambana endaweni yomugqa ophakathi nendawo.Ukuthwala umugqa owodwa kungathwala umthwalo we-radial kanye nomthwalo we-axial wendlela eyodwa, futhi ukuthwala imigqa emibili kungathwala umthwalo we-radial kanye nomthwalo we-axial wendlela-mbili, ofanele ukuthwala umthwalo osindayo kanye nomthwalo womthelela.
I-roller ene-tapered
Izinhlelo zokusebenza eziyinhloko: Imoto: isondo langaphambili, isondo elingemuva, ukudluliselwa, umugqa we-pinion ohlukile.Ithuluzi lokuphotha lomshini, imishini yokwakha, imishini emikhulu yezolimo, isinciphisi segiya lemoto kaloliwe, intamo yokugaya eginqikayo nesinciphisi.
6. Ibhola le-groove elijulile
Ngokwesakhiwo, iringi ngayinye yebhola le-deep groove inomzila womjaho oqhubekayo onengxenye ephambanayo cishe ingxenye eyodwa kwezintathu yomjikelezo webhola oyindilinga yenkabazwe.I-deep groove ball bearing isetshenziselwa ikakhulukazi ukuthwala umthwalo we-radial, kodwa futhi ingathwala umthwalo othile we-axial.
Lapho ukucaciswa kwe-radial kwe-bearing kukhuphuka, kunempahla ye-angular contact ball bearing futhi ingathwala umthwalo we-axial oshintshanayo ngezindlela ezimbili.Uma kuqhathaniswa nezinye izinhlobo zamabhere ezinobukhulu obufanayo, lolu hlobo lokuthwala lune-coefficient encane yokungqubuzana, isivinini somkhawulo ophezulu kanye nokunemba okuphezulu.Iwuhlobo oluthandwayo olukhethwa abasebenzisi.
Ibhola le-deep groove
Ukusetshenziswa okuyinhloko: imoto, ugandaganda, ithuluzi lomshini, injini, iphampu yamanzi, imishini yezolimo, imishini yendwangu, njll.
7. I-Trust ball bear
Yakhiwe indandatho yomjaho emise okwe-washer enomgwaqo womjaho, ibhola kanye nomhlangano wekheji.Indandatho yomjaho ehambisana ne-shaft ibizwa ngokuthi indandatho ye-shaft, futhi indandatho yomjaho ehambisana nendlu ibizwa ngokuthi indandatho yokuhlala.I-average enezinhlangothi ezimbili ilingana neringi emaphakathi ne-shaft eyimfihlo.Ukuthwala kwendlela eyodwa kungathwala umthwalo we-axial wendlela eyodwa, futhi ukuthwala kwezindlela ezimbili kungathwala umthwalo we-axial wezindlela ezimbili (futhi awukwazi ukuthwala umthwalo we-radial).
I-thrust ball bear
Ukusetshenziswa okuyinhloko: iphinikhodi yokuqondisa imoto, ithuluzi lokuphotha lomshini.
8. I-Trust roller bear
I-thrust roller bear isetshenziselwa ukuthwala i-shaft enomthwalo we-axial njengomthwalo oyinhloko, futhi umthwalo we-longitudinal akufanele udlule u-55% womthwalo we-axial.Uma kuqhathaniswa namanye ama-thrust roller bearings, lolu hlobo lokuthwala lune-coefficient ephansi yokungqubuzana, isivinini esiphezulu sokuzungeza kanye nekhono lokuziqondanisa.Irola ye-29000 bear iyi-asymmetric spherical roller, enganciphisa ukushelela okuhlobene kwenduku kanye nomjaho womjaho emsebenzini.Ngaphezu kwalokho, i-roller yinde futhi inkulu ububanzi, inenani elikhulu lama-roller kanye nomthamo omkhulu womthwalo.Ivamise ukugcotshwa ngamafutha, futhi amafutha angasetshenziselwa izimo ezinejubane eliphansi ngazinye.
I-Trust roller bear
Ukusetshenziswa okuyinhloko: i-hydraulic generator, i-crane hook.
9. I-Cylindrical roller bearing
I-roller ye-cylindrical roller bear ngokuvamile iqondiswa imiphetho emibili yeringi yokuthwala.Irola yekheji kanye nendandatho yomhlahlandlela kwakha umhlangano, ongahlukaniswa kwenye indandatho yokuthwala.Kungokuthwala okuhlukanisekayo.
Ukuthwala kulula ukufaka nokuhlakaza, ikakhulukazi uma izindandatho zangaphakathi nangaphandle zidingeka ukuba zibe ukuphazamiseka okuhambisana ne-shaft nezindlu.Lolu hlobo lokuthwala ngokuvamile lusetshenziselwa ukuthwala umthwalo we-radial.Umugqa owodwa kuphela onamasongi angaphakathi nangaphandle anemiphetho ebambayo ongathwala i-axial encane enganyakazi noma umthwalo omkhulu we-axial wezikhawu.
I-Cylindrical roller bearing
Izinhlelo zokusebenza eziyinhloko: amamotho amakhulu, ama-spindle amathuluzi omshini, amabhokisi e-axle, ama-crankshafts enjini ye-diesel, izimoto, amabhokisi okuguqula, njll.
