Iibheringi eziqengqelekayo ezahlukeneyo zineempawu ezahlukeneyo kwaye zifanelekile kwiimeko ezahlukeneyo zokusetyenziswa kwezixhobo ezahlukeneyo zomatshini. Abasebenzi abakhethiweyo kufuneka bakhethe imodeli efanelekileyo yokuthwala abavelisi abahlukeneyo kunye neentlobo ezininzi zokuthwala.
1. Khetha imodeli yokuthwala ngokwendawo kunye nesikhundla sesixhobo somatshini esithathwe yibheringi:
Ngokuqhelekileyo sisebenzisa ibholaiibheringikwiishafu ezincinci, kunye neebheringi zeerola zeeshafu ezinkulu. Ukuba ububanzi bebheringi bulinganiselwe, sisebenzisa ngokubanzi iibheringi zeenaliti, iibheringi zebhola ezikhanyayo okanye iibheringi; xa ukuthwala kunqunyelwe kwi-axial inxalenye yesixhobo, uchungechunge oluncinci okanye oluncinci lweebhola zebhola okanye ii-roller bearings.
2. Khetha imodeli yokuthwala ngokomthwalo. Umthwalo kufuneka ube yeyona nto ibalulekileyo ekufuneka iqwalaselwe xa ukhetha iibheringi:
Iibheringi ze-roller ziyakwazi ukumelana nemithwalo emikhulu, ngelixa iibhola zebhola zincinci. Iibheringi ezenziwe ngentsimbi ye-carburized ziyakwazi ukumelana nokutshitshiswa kunye nemithwalo ye-vibration. Xa kufuneka imithwalo ye-radial emsulwa, sinokukhetha iibheringi zebhola eziphoswayo, iibheringi ze-cylindrical roller okanye iibheringi zeenaliti. Xa umthwalo we-axial uncinci, sinokukhetha i-thrust ball bear; xa umthwalo we-axial umkhulu kakhulu, i-thrust roller bear isetyenziswa ngokubanzi. Xa ukuthwala kuthwala zombini imithwalo ye-axial kunye ne-radial, ngokuqhelekileyo sisebenzisa ii-angular zoqhagamshelwano zebhola okanye ii-roller bearings tapered.
3. Ngokweempawu zokuzilungelelanisa zokuthwala, khetha imodeli yokuthwala:
Xa i-axis ye-shaft ingafani ne-axis yesihlalo sokuthwala, okanye kulula ukugoba okanye ukugotywa phantsi koxinzelelo, ibhola elizilungelelanisayo okanye i-self-aligning roller ephethe umsebenzi obalaseleyo wokuzilungelelanisa, kwaye ukuthwala ibhola yangaphandle kungakhethwa. Olu hlobo lokuthwala lunokuqinisekisa umsebenzi oqhelekileyo xa i-shaft ijika okanye igobile. I-pros and cons of the bearing's self-aligning function inxulumene nokungabikho kwe-axiality enokwenzeka. Ixabiso elikhulu, ngcono ukusebenza kokuzilungelelanisa.
4. ngokobunzima bokuthwala, khetha imodeli yokuthwala:
I-deformation elastic of rollingiibheringiAyinkulu kwaye inokungahoywa kuninzi lwezixhobo zoomatshini, kodwa kwezinye izixhobo zoomatshini, ezinje ngeespindle zesixhobo somatshini, ukuthwala ukuqina ngumba ophambili.
Ngokuqhelekileyo sisebenzisa iibheringi ze-cylindrical roller okanye iibheringi ze-tapered roller zesixhobo somatshini. Ngenxa yokuba ezi ntlobo zimbini zeebheringi zezoqhagamshelwano lwamanqaku xa uphantsi komthwalo, ukuqina akunamandla.
Ukongeza, iibheringi ezahlukeneyo zinokusebenzisa ukulayisha kwangaphambili ukunyusa ukuqina kokuthwala. Okufana neebheringi zebhola zoqhagamshelwano kunye ne-tapered roller bearings, ukwenzela ukuba kuphuculwe ukuqina kwenkxaso, i-axial force ethile idla ngokudibaniswa kwangaphambili ngexesha lendibano ukubenza babambene. Igxininiswe ngakumbi apha: amandla okulayisha kwangaphambili akanakuba mkhulu kakhulu. Ngaphandle koko, ukungqubuzana kokuthwala kunokunyuka, ukunyuka kweqondo lokushisa kuya kwanda, kwaye ubomi benkonzo yokuthwala buya kuba sengozini.
5. ngokwesantya sokuthwala, khetha imodeli yokuthwala:
Ngokuqhelekileyo, ii-angular contact bearings kunye ne-cylindrical roller bearings zifanelekile ukusetyenziswa kwiindawo zokusebenzela ezihamba ngesantya esiphezulu; iibheringi tapered roller zingasetyenziswa kwiindawo zokusebenza ezinesantya esiphantsi. Iibheringi zebhola ezithrust zinesantya esisezantsi kwaye zifanelekile kuphela kwiindawo ezinezantya ezisezantsi.
Kuhlobo olufanayo lokuthwala, inkcazo encinci, iphezulu isantya esivumelekileyo sokujikeleza. Xa ukhetha imodeli yokuthwala, nikela ingqalelo kwisantya sangempela esingaphantsi kwesantya somda.
