I-bearing ayifakwanga kakuhle. Ingxaki imbi kakhulu!
Abasebenzisi bahlala bekhalaza ngobomi benkonzo yeebheringi, kodwa i-80% yeebheringi iyasilela ngaphambi kwexesha ngenxa yokufakelwa okungafanelekanga. Ukufakelwa ngokuchanekileyo kweebheringi akunakunyusa ubomi benkonzo yazo kuphela kwaye kunciphise iindleko, kodwa kukwaphucula kakhulu ukusebenza kakuhle kwemveliso.
Njengoko kwaziwa kakuhle, iibheringi ngokwazo zizinto ezisetyenziselwa inkxaso kunye neendawo ezisetyenziselwa ukuxhasa ukujikeleza kwiishafts. Iibheringi zinokuhlulwa ngokweempawu zazo zokungqubana zibe ziibheringi ezityibilikayo kunye neebheringi eziqengqelekayo. Ngokwendlela umthwalo eziwuthwele ngayo, kukho iibheringi zeradial, Ukuthwala iThrouthis, kunye neebheringi ze-radial thrust, njl.
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 ezislayidayo ezidibeneyo
Iibheringi ezityibilikayo ezidityanisiweyo, ezaziwa ngokuba zii-bushings, zezona ndlela zilula zeebheringi ezityibilikayo. Zihlanganiswa ngokucinezela ngaphakathi nangokubetha ngehammer. Kwiimeko ezikhethekileyo, kusetyenziswa indlela yokufaka eshushu. Uninzi lwee-bushings zenziwe nge-copper okanye ngentsimbi ephosiweyo. Ngexesha lokuhlanganisa, kufuneka kuthathwe unonophelo. Zingadityaniswa ngokubethela ngehammer yomthi okanye ngehammer ngebhloko yomthi. Xa ukunyamezelana kokuphazamiseka kukhulu, kufuneka zicinezelwe ngaphakathi ngokucinezela. Nokuba zibethelelwe 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. Kwizincinci, ii-reamers zingasetyenziselwa ukunqunyulwa; kwezinkulu, kufuneka kusetyenziswe ii-scrapers. Kwangaxeshanye, qaphela ukulawula indawo evulekileyo kunye ne-shaft ngaphakathi koluhlu lokunyamezela. Ukuthintela i-shaft sleeve ukuba ingajikelezi ngexesha lokusebenza, kufakwa ii-positioning pins okanye ii-cross-seam screws kumphezulu woqhagamshelwano phakathi kwe-shaft sleeve kunye ne-housing. Ngenxa yobunzima obahlukeneyo bomzimba webhokisi kunye nezinto ze-shaft sleeve, xa kugqojozwa, kulula kakhulu ukuba i-drill bit ithambekele kwicala lezinto ezithambileyo. Izisombululo zezi: okokuqala, sebenzisa i-sample punch ukugqobhoza umngxuma kwicala lezinto eziqinileyo ngaphambi kokugqobhoza; okwesibini, sebenzisa i-short bit ukwandisa ukuqina kwe-drill bit ngexesha lokugqobhoza.
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.
● 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.
● 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.
● 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 sebheringi siqinisiwe, ishaft inokujikeleza ngokukhululekileyo ngaphandle kokuphuma okucacileyo, kwaye iindawo zokunxibelelana ziyahlangabezana neemfuno, ukukhuhla kugqityiwe.
● Ukulinganiswa kwesithuba sokuthwala
Ubungakanani bendawo yokubeka intsimbi bunokulungiswa yi-gasket esembindini okanye ngokukrwela ngokuthe ngqo i-bearing bush. Indawo yokubeka intsimbi idla ngokulinganiswa ngendlela yokucinezela i-lead. Thatha amacandelo aliqela e-lead wire anobubanzi obukhulu kune-bearing clearance uze uwabeke kwi-jenali kunye nomphezulu ophakathi wokubeka intsimbi. Emva koko qinisa i-nut ukuze ucinezele umphezulu ophakathi wokubeka intsimbi ngokuqinileyo, vula i-nut, susa isigqubuthelo se-bearing, kwaye ukhuphe ngononophelo i-lead wire ethe tyaba. Sebenzisa i-micrometer ukulinganisa ubukhulu becandelo ngalinye elithathiweyo. Ngokusekelwe kubukhulu obuphakathi be-lead wire, indawo yokubeka intsimbi ingaziwa. Indawo yokubeka intsimbi ngokubanzi kufuneka ibe yi-1.5‰-2.5‰ (mm) yobubanzi be-shaft. Xa ububanzi bukhulu, kufuneka kuthathwe ixabiso elincinci lokubeka intsimbi. Ukuba ububanzi be-shaft 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 ibhereji ihlanganiswe kwi-shaft nakwindawo yokuhlala, akufuneki kubekho 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℃.
