I-bearing ayifakwanga kakuhle. Ingxaki imbi kakhulu!
Ukuhlanganiswa kweebheringi ezityibilikayo
Iibheringi ezityibilikayo luhlobo lweebheringi ezineempawu zokungqubana okutyibilikayo. Zibonakaliswa kukusebenza kakuhle, ukuthembeka, ingxolo ephantsi, kunye nokukwazi ukumelana nemithwalo enzima kunye nemithwalo ebalulekileyo yempembelelo. Ngokweefom ezahlukeneyo zesakhiwo, zinokwahlulwa zibe yi-integral type, split type, kunye ne-block type, njl.njl.
1. Ukuhlanganiswa kweebheringi ezityibilikayo ezidibeneyo
Iibheringi ezityibilikayo ezihlanganisiweyo, ezaziwa ngokuba zii-bushings, zezona ndlela zilula kakhulu zeebheringi ezityibilikayo. Zihlanganiswa ngokucinezela ngaphakathi nangokubetha ngehammer. Kwiimeko ezikhethekileyo, kusetyenziswa indlela yokufakela eshushu. Uninzi lwee-bushings zenziwe ngobhedu okanye ngentsimbi ephosiweyo.
Ngexesha lokuhlanganisa, kufuneka kuqatshelwe. Zingahlanganiswa ngokuzibetha ngesando somthi okanye ngesando esinebhloko yomthi. Xa ukunyamezelana kokuphazamiseka kukhulu, kufuneka zicinezelwe nge-press. Nokuba zibethelwe ngaphakathi okanye zicinezelwe ngaphakathi, ukuthambeka kufuneka kuthintelwe. Emva kokuhlanganisa, umngxuma weoyile kunye nomngxuma weoyile kufuneka ube kwindawo efunekayo.
Kwiibheringi eziguquguqukileyo emva kokuhlanganiswa, imingxunya yangaphakathi kufuneka inqunyulwe. Kwiincinci, ii-reamers zingasetyenziselwa ukunqunyulwa; kwezinkulu, kufuneka kusetyenziswe ii-scrapers. Kwangaxeshanye, qaphela ukulawula indawo evulekileyo kunye ne-shaft ngaphakathi koluhlu lokunyamezelana.
Ukuthintela isingxobo se-shaft ukuba singajikelezi ngexesha lokusebenza, kufakwa izikhonkwane zokubeka okanye izikrufu ezinqamlezileyo kumphezulu woqhagamshelwano phakathi kwesingxobo se-shaft kunye ne-housing. Ngenxa yobunzima obahlukeneyo bomzimba webhokisi kunye nezinto zesingxobo se-shaft, xa kugrunjwa, kulula kakhulu ukuba i-drill bit ithambekele kwicala lezinto ezithambileyo. Izisombululo zezi:
* Okokuqala, sebenzisa isampuli yokubhoboza umngxuma kwicala eliqinileyo lezinto ngaphambi kokubhoboza
* Okwesibini, sebenzisa i-drill bit emfutshane ukuze wonyuse ubulukhuni be-drill bit ngexesha lokugrumba.
2. Ukuhlanganiswa kweebheringi eziqhekekileyo
Iibheringi eziqhekekileyo, ezaziwa ngokuba ziibheringi eziqhekekileyo, zinesakhiwo esilula kwaye kulula ukuzilungisa nokuziqhekeza. Iibheringi ezimbini zeebheringi zifakwa kwiibheringi zeebheringi, kwaye kusetyenziswa i-gasket kwindawo edibeneyo ukulungisa umsantsa ofanelekileyo.
*A. Ukuhlanganiswa kwesihlahla esithwalayo kunye Indlu yeebheringi
Ukudibana phakathi kwamaqokobhe angaphezulu nasezantsi eebhereyitha kunye nomngxuma wangaphakathi wendlu yeebhereyitha kufuneka kube kuhle. Ukuba ayihlangabezani neemfuno, sebenzisa umngxuma wangaphakathi wendlu yeebhereyitha yegobolondo leebhereyitha elinodonga olude njengesalathiso sokukrwela umva wegobolondo leebhereyitha. Kwangaxeshanye, amanyathelo amabini kuzo zombini iziphelo zegobolondo leebhereyitha kufuneka abe kufutshane neziphelo ezibini zendlu yeebhereyitha. Kwiigobolondo zeebhereyitha ezinodonga oluncinci, kuyimfuneko kuphela ukwenza i-midplane yegobolondo leebhereyitha ibe malunga ne-0.1mm ngaphezu kwendlu yeebhereyitha, kwaye akukho mfuneko yokuyikrwela.
*B. Iimfuneko zokubeka indawo
Isihlahla sokuthwala sifakwe kwindawo yokuthwala kwaye asivumelekanga ukuba sibe notshintsho nokuba lujikeleze nge-radially okanye nge-axial. Ngokwesiqhelo, simiswa size sibekwe ngamanyathelo kuzo zombini iziphelo zesihlahla sokuthwala okanye ngezikhonkwane zokubeka.
*C. Ukukrwela amaqokobhe okuthwala
Kwiigobolondo zeebheringi eziqhekekileyo, kusetyenziswa iindawo zokusila ezihambelanayo. Ngokwesiqhelo, igobolondo lebheringi liyakhuhlwa kuqala, emva koko igobolondo lebheringi eliphezulu liyakhuhlwa. Ukuphucula ukusebenza kakuhle, igobolondo lebheringi kunye nesigqubuthelo akufuneki zifakwe xa kukhuhlwa igobolondo lebheringi. Xa indawo yokunxibelelana yegobolondo lebheringi elisezantsi ihlangabezana neemfuno, igobolondo lebheringi eliphezulu kunye nesigqubuthelo esingaphezulu zicinezelwe ngokuqinileyo. Ngexesha lokukhuhla igobolondo lebheringi eliphezulu, indawo yokunxibelelana yegobolondo lebheringi elisezantsi iyalungiswa ngakumbi. Xa kukhuhlwa, ukuqina kweshaft kunokulungiswa ngokutshintsha ubukhulu begasket njengoko inani lamaxesha okukhuhla lisanda. Xa Isigqubuthelo sokuthwala iqinisiwe, umngxuma ungajikeleza ngokukhululekileyo ngaphandle kokuvula okucacileyo, kwaye iindawo zokunxibelelana ziyahlangabezana neemfuno, ukukrwela kugqityiwe.
*D. Ukulinganiswa kwesithuba sokuthwala
Ubungakanani bendawo evulekileyo bunokulungiswa yi-gasket esembindini okanye ngokukrwela ngokuthe ngqo isihlahla sendawo evulekileyo. Indawo evulekileyo idla ngokulinganiswa ngendlela yokucinezela i-lead:
1. Thatha amacandelo aliqela entambo yentsimbi enobubanzi obukhulu kunesithuba sebheyari
2. Zibeke kwijenali kunye nomphezulu ophakathi wokwahlukana
3. Qinisa i-nut ukuze ucinezele kakuhle umphezulu ophakathi wokwahlulahlula
4. Khulula i-nut uze ususe isigqubuthelo sebhereyitha
5. Khupha ngononophelo ucingo lwentsimbi olusicaba
6. Sebenzisa i-micrometer ukulinganisa ubukhulu becandelo ngalinye
Ngokusekelwe kubukhulu obuqhelekileyo bentambo yentsimbi ekhokelayo, indawo yokubeka intsimbi ingaziwa. Indawo yokubeka intsimbi ngokubanzi kufuneka ibe yi-1.5‰-2.5‰ (mm) yobubanzi bentsimbi. Xa ububanzi bukhulu, kufuneka kuthathwe ixabiso elincinci lokubeka intsimbi. Ukuba ububanzi bentsimbi buyi-60mm, indawo yokubeka intsimbi kufuneka ibe phakathi kwe-0.09 kunye ne-0.15mm.
Ukuhlanganiswa kweebheringi eziqengqelekayo
Iibheringi eziqengqelekayo zinezibonelelo zokungqubana okuphantsi, ubukhulu obuncinci be-axial, ukutshintshwa okulula kunye nokugcinwa okulula.
Iimfuno zobugcisa zokuhlanganisa:
* Isiphelo seebheringi eziqengqelekayo eziphawulwe ngeekhowudi kufuneka zifakwe kwicala elibonakalayo ukuze kube lula ukuqinisekiswa ngexesha lokutshintshwa.
* Irediyasi ye-arc kwinqanaba lejenali okanye umngxuma wendlu kufuneka ibe ncinci kunaleyo ikwindawo ehambelanayo kwi-bearing.
* Emva kokuba i-bearing idityanisiwe kwi-shaft nakwi-housing hole, akufuneki kubekho i-skew.
* Phakathi kweebheringi ezimbini ezikwi-axis enye, umntu kufuneka abangele ukuba i-shaft ishukume xa i-shaft isanda ngobushushu.
* Xa uhlanganisa iibheringi eziqengqelekayo, kubalulekile ukuthintela ngokungqongqo ukungcola ukuba kungangeni kwiibheringi.
* Emva kokuhlanganiswa, iibheringi mazisebenze ngokuguquguquka, zivelise ingxolo ephantsi, kwaye ubushushu bokusebenza ngokubanzi akufuneki budlule kwi-65℃.
