Ukuhlanganiswa kwama-bearings ashelelayo
Ama-bearings ashelelayo awuhlobo lwe-bearings olunezakhiwo zokungqubuzana ezishelelayo. Abonakala ngokusebenza okubushelelezi, ukuthembeka, umsindo ophansi, kanye nekhono lokubekezelela imithwalo esindayo kanye nemithwalo ebalulekile yomthelela. Ngokwezinhlobo ezahlukene zesakhiwo, angahlukaniswa ngohlobo oluhlanganisiwe, uhlobo oluhlukanisiwe, kanye nohlobo lwebhulokhi, njll.
1. Ukuhlanganiswa kwama-bearings aslayidayo ahlanganisiwe
Ama-bearings asliding ahlanganisiwe, aziwa kakhulu ngokuthi ama-bushings, ayindlela elula kakhulu yama-bearings asliding. Ahlanganiswa kakhulu ngokucindezela ngaphakathi nangokushaya ngesando. Ezimweni ezikhethekile, kusetshenziswa indlela yokufaka eshisayo. Ama-bushings amaningi enziwe ngethusi noma ngensimbi ephonswe ngensimbi.
Ngesikhathi sokuhlanganiswa, kufanele kuqashelwe. Zingahlanganiswa ngokushaya ngesando sokhuni noma ngesando ngebhlokhi lokhuni. Uma ukubekezelelana kokuphazamiseka kukhulu, kufanele zicindezelwe ngokucindezela. Kungakhathaliseki ukuthi zishayiwe noma zicindezelwe, ukuthambekela kumele kuvinjelwe. Ngemva kokuhlanganiswa, umsele wamafutha kanye nembobo kawoyela kufanele kube sesimweni esidingekayo.
Kuma-bearing aguqukile ngemva kokuhlanganiswa, imigodi yangaphakathi kufanele inqunywe. Kwabancane, ama-reamer angasetshenziswa ukusika; kwabakhulu, kufanele kusetshenziswe ama-scraper. Ngesikhathi esifanayo, naka ukulawula indawo evulekile ne-shaft ngaphakathi kwebanga lokubekezelelana.
Ukuze kuvinjelwe ukuthi isivikelo somshafti singajikelezi ngesikhathi sokusebenza, kufakwa izikhonkwane zokubeka noma izikulufo ezivundlile endaweni yokuxhumana phakathi kwesivikelo somshafti kanye nendlu. Ngenxa yobunzima obuhlukene bomzimba webhokisi nezinto zomshafti, lapho kubholwa, kulula kakhulu ukuthi i-drill bit incike ohlangothini lwezinto ezithambile. Izixazululo yilezi:
* Okokuqala, sebenzisa isampula yokubhoboza umgodi ohlangothini lwezinto eziqinile ngaphambi kokubhoboza
* Okwesibili, sebenzisa i-drill bit emfushane ukuze wandise ukuqina kwe-drill bit ngesikhathi sokubhoboza.
2. Ukuhlanganiswa kwama-split bearings
Ama-split bearings, aziwa nangokuthi ama-split bearings, anesakhiwo esilula futhi kulula ukuwalungisa nokuwahlukanisa. Ama-bearings amabili afakwa kuma-bearings shells, bese kusetshenziswa i-gasket endaweni yokuhlangana ukulungisa igebe elifanele.
*A. Ukuhlanganiswa kwesihlahla esithwalayo kanye nesihlahla Izindlu Zokuthwala
Ukuxhumana phakathi kwamagobolondo angaphezulu nangaphansi okuthwala kanye nembobo yangaphakathi yendlu yokuthwala kumele kube kuhle. Uma ingahlangabezani nezidingo, sebenzisa imbobo yangaphakathi yendlu yokuthwala yegobolondo lokuthwala elinodonga olujiyile njengereferensi yokuklwebha ngemuva kwegobolondo lokuthwala. Ngesikhathi esifanayo, izinyathelo ezimbili kuzo zombili iziphetho zegobolondo lokuthwala kufanele zibe seduze nemikhawulo emibili yendlu yokuthwala. Kumagobolondo okuthwala anodonga oluncane, kuyadingeka kuphela ukwenza i-midplane yegobolondo lokuthwala ibe cishe ngu-0.1mm ngaphezu kwendlu yokuthwala, futhi asikho isidingo sokuyiklwebha.
*B. Izidingo zokubeka indawo
Isihlahla esithwalayo sifakwe endlini yokuthwala futhi asivunyelwe ukuba nanoma yikuphi ukufuduka kungaba nge-radially noma nge-axial. Ngokuvamile, siyamiswa futhi sibekwe yizitebhisi kuzo zombili iziphetho zesihlahla esithwalayo noma ngezikhonkwane zokubeka.
*C. Ukuklwebheka kwamagobolondo okuthwala
Kumagobolondo okuthwala ahlukene, izindawo zokugaya ezihambisanayo zivame ukusetshenziswa. Ngokuvamile, igobolondo lokuthwala liyakhuhlwa kuqala, bese igobolondo lokuthwala eliphezulu liyakhuhlwa. Ukuze kuthuthukiswe ukusebenza kahle, igobolondo lokuthwala kanye nesembozo akudingeki kufakwe lapho kukhuhlwa igobolondo lokuthwala. Lapho iphuzu lokuxhumana legobolondo lokuthwala eliphansi lihlangabezana nezidingo, igobolondo lokuthwala eliphezulu kanye nesembozo esiphezulu kuyacindezelwa kakhulu. Ngesikhathi kukhuhlwa igobolondo lokuthwala eliphezulu, iphuzu lokuxhumana legobolondo lokuthwala eliphansi liyalungiswa ngokwengeziwe. Lapho kukhuhlwa, ukuqina kweshaft kungalungiswa ngokushintsha ubukhulu be-gasket njengoba inani lezikhathi zokukhuhla landa. Lapho Isembozo Sokuthwala iqinisiwe, umgodi ungajikeleza ngokukhululeka ngaphandle kokuvula okusobala, futhi izindawo zokuthintana ziyahlangabezana nezidingo, ukuklwebheka sekuqediwe.
*D. Ukulinganiswa kwesikhala sokuthwala
Usayizi wesikhala sebhereyitha ungalungiswa yi-gasket ephakathi nendawo noma ngokuklwebha ngqo isihlahla sebhereyitha. Isikhala sebhereyitha sivame ukukalwa ngendlela yokucindezela i-lead:
1. Thatha izingxenye eziningana zocingo lomthofu olunobubanzi obukhulu kunesikhala sokuthwala
2. Zibeke ephepheni kanye nasendaweni ephakathi nendawo yokuhlukana
3. Qinisa i-nut ukuze ucindezele kahle indawo ephakathi nendawo yokuhlukana
4. Khulula i-nut bese ususa isembozo sebhereyitha
5. Khipha ngokucophelela ucingo lomthofu oluyisicaba
6. Sebenzisa i-micrometer ukukala ubukhulu besigaba ngasinye
Ngokusekelwe ekujikeni okujwayelekile kwentambo yokudonsa, i-bearing clearance ingaziwa. I-clearance ye-bearing ejwayelekile kufanele ibe ngu-1.5‰-2.5‰ (mm) yobubanzi bomgodi. Uma ububanzi bukhulu, kufanele kuthathwe inani elincane le-clearance. Uma ububanzi bomgodi bungu-60mm, i-breathing clearance kufanele ibe phakathi kuka-0.09 no-0.15mm.
Ukuhlanganiswa kwama-rolling bearings
Ama-rolling bearings anezinzuzo zokungqubuzana okuphansi, ubukhulu obuncane be-axial, ukushintshwa okulula kanye nokugcinwa okulula.
Izidingo zobuchwepheshe zokuhlanganisa:
* Ubuso bokugcina bama-rolling bearings aphawulwe ngamakhodi kufanele bufakwe ohlangothini olubonakalayo ukuze kube lula ukuqinisekiswa ngesikhathi sokufakwa esikhundleni.
* Irediyasi ye-arc esitebhisini sejenali noma umgodi wendlu kufanele ibe ncane kunaleyo esendaweni ehambisanayo kubhereyi.
* Ngemva kokuba i-bearing ihlanganiswe emgodleni nasemgodini wendlu, akufanele kube khona ukugoba.
* Phakathi kwama-bearings amabili ku-axis efanayo, umuntu kumele abangele ukuthi i-shaft inyakaze lapho i-shaft ikhula ngokushisa.
* Lapho kuhlanganiswa ama-rolling bearings, kubalulekile ukuvimbela ngokuqinile ukungcola ukuthi kungangeni kuma-bearings.
* Ngemva kokuhlanganiswa, amabheringi kufanele asebenze ngokuguquguqukayo, akhiqize umsindo ophansi, futhi izinga lokushisa lokusebenza ngokuvamile akufanele lidlule ku-65℃.
