Ukukhethwa kwe-bearing clearance kanye nokucushwa kuyingxenye ebaluleke kakhulu yokwakhiwa kwezimoto, futhi isisombululo esikhethiwe ngaphandle kokwazi ukusebenza kwe-bearing kungenzeka sibe umklamo ohlulekile.Izimo zokusebenza ezihlukene zinezidingo ezihlukene zamabheringi.

Inhloso yokufaka i-lubrication ukuhlukanisa into egoqayo kanye ne-rolling surface ngefilimu encane yamafutha, futhi kwakhiwe ifilimu yamafutha okugcoba afanayo endaweni egoqayo ngesikhathi sokusebenza, ngaleyo ndlela kuncishiswe ukungqubuzana kwangaphakathi kwe-bearing kanye nokugqokwa kwento ngayinye, ukuvimbela sintering.Ukugcoba okuhle kuyisimo esidingekayo ukuze i-bearing isebenze.Ukuhlaziywa kwezimbangela zomonakalo wokuzala kukhombisa ukuthi cishe amaphesenti angama-40 omonakalo wokuthwala uhlobene nokugcotshwa okungekuhle.Izindlela zokugcoba zihlukaniswe zibe ukuthambisa kwamafutha kanye nokugcotshwa kwamafutha.

Ukugcoba kwamafutha kunenzuzo yokuthi akudingi ukugcwaliswa isikhathi eside ngemva kokugcwalisa ngamafutha kanye, futhi isakhiwo sokubeka uphawu silula, ngakho sisetshenziswa kabanzi.Igrisi isithambisi esiqinile esakhiwe ngamafutha okugcoba njengamafutha ayisisekelo futhi ahlanganiswe ne-thickener eqinile ene-lipophilicity eqinile.Ukuze uthuthukise ezinye izici, izithasiselo ezihlukahlukene nazo zengezwa.Ukugcotshwa kukawoyela, ngokuvamile okuhlanganisa ukugcotshwa kukawoyela ojikelezayo, ukuthambisa kwejethi, nokuthambisa inkungu kawoyela.Amafutha okugcoba ama-bearings ngokuvamile asekelwe kumafutha amaminerali acwengekile anokuqina okuhle kwe-oxidation nokumelana nokugqwala, namandla aphezulu efilimu kawoyela, kodwa amafutha ahlukahlukene okwenziwa avame ukusetshenziswa.

Ukuhlelwa kwezingxenye ezijikelezayo zenjini (njenge-shaft eyinhloko) ngokuvamile idinga ukusekelwa amasethi amabili ama-bearings, futhi ingxenye ejikelezayo ibekwe nge-radially kanye ne-axially ngokuhlobene nengxenye engashintshi yomshini (njenge-bearing. isihlalo).Kuye ngezimo zesicelo, ezifana nomthwalo, ukunemba okujikelezayo okudingekayo kanye nezidingo zezindleko, amalungiselelo okuthwala angahlanganisa lokhu okulandelayo: Ukuthwala amalungiselelo aneziphetho ezingaguquki nezintantayo Amalungiselelo okuthwala alungiswe kusengaphambili (amiswe kuzo zombili iziphetho) ” “Floating” ukucushwa kokuthwala okuhle ( izinhlangothi zombili ziyantanta)

I-fixed end bearing isetshenziselwa ukusekelwa kwe-radial ekugcineni kwe-shaft kanye nokubeka i-axial ezindaweni ezimbili ngesikhathi esisodwa.Ngakho-ke, i-bearing end bearing kufanele ilungiswe ku-shaft kanye nezindlu ezithwala ngesikhathi esifanayo.Amabherethi afanele ukusetshenziswa ekugcineni okungaguquki ama-radial bearings akwazi ukumelana nemithwalo ehlanganisiwe, njengama-deep groove ball bearings, imigqa ephindwe kabili noma ama-angular othintana nawo womugqa owodwa, ama-self-aligning ball bearings, ama-spherical and roller bearings noma ama-roller ama-tapered ahambisanayo. .sub bear.Ama-radial bearings akwazi ukuthwala kuphela imithwalo emsulwa ye-radial, njengama-roller cylindrical roller aqinile anendandatho eyodwa engenazimbambo, nezinye izinhlobo zamabheringi (njengama-deep groove ball bearings, ama-ball contact bearing anamaphuzu amane noma ama-thrust bearings amabili) njll.) futhi ingasetshenziswa ekugcineni lapho isetshenziswa ngamaqembu.Kulokhu kumiswa, enye i-areying isetshenziselwa kuphela ukuma kwe-axial ezinhlangothini ezimbili, futhi izinga elithile lenkululeko ye-radial kufanele lishiywe esihlalweni esiphethe (okungukuthi, imvume kufanele igcinwe nesihlalo esinesihlalo).

I-axial end bearing isetshenziselwa kuphela ukusekelwa kwe-radial komunye umkhawulo we-shaft, futhi i-shaft kufanele ivunyelwe ukuba ne-axial displacement ethile, ukuze kungabikho amandla okubambisana phakathi kwama-bearings.Isibonelo, lapho ukuthwala kunwebeka ngenxa yokushisa, i-axial displacement ingaba Ezinye izinhlobo zamabheringi zisetshenziswa ngaphakathi.I-axial displacement ingenzeka phakathi kwelinye lamasongo kanye nengxenye axhumeke kuyo, okungcono phakathi kwendandatho yangaphandle kanye ne-bore yezindlu.
