Ibhereyi ayifakwanga kahle. Inkinga inkulu kakhulu!
Abasebenzisi bahlala bekhononda ngokuphila kwenkonzo yama-bearings, kodwa ama-80% ama-bearings ahluleka ngaphambi kwesikhathi ngenxa yokufakwa okungalungile. Ukufakwa kahle kwama-bearings akugcini nje ngokwandisa impilo yawo yenkonzo futhi kunciphise izindleko, kodwa futhi kuthuthukisa kakhulu ukusebenza kahle kokukhiqiza.
Njengoba kwaziwa kahle, ama-bearings ngokwawo ayizingxenye ezisetshenziselwa ukusekela kanye nezingxenye ezisetshenziselwa ukusekela ukujikeleza kuma-shafts. Ama-bearings angahlukaniswa ngezakhiwo zawo zokungqubuzana abe ama-bearings ashelelayo nama-rolling bearings. Ngokuya kwesiqondiso somthwalo athwele, kukhona ama-radial bearings, Ukuthwala Okugxililes, kanye nama-radial thrust bearings, njll.
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. Angahlanganiswa ngokushaya ngesando sokhuni noma ngesando ngebhlokhi lokhuni. Uma ukubekezelelana kokuphazamiseka kukhulu, kufanele acindezelwe ngokucindezela. Kungakhathaliseki ukuthi kushayiwe noma kucindezelwe ngaphakathi, ukuthambekela kumele kuvinjelwe. Ngemva kokuhlanganiswa, umsele wamafutha kanye nembobo yamafutha 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 efanelekile ne-shaft ngaphakathi kwebanga lokubekezelela. Ukuvimbela i-shaft sleeve ukuthi ingajikelezi ngesikhathi sokusebenza, kufakwa amaphini okubeka noma izikulufo ezivundlile endaweni yokuxhumana phakathi kwe-shaft sleeve kanye ne-housing. Ngenxa yobunzima obuhlukile bomzimba webhokisi nezinto ze-shaft sleeve, lapho kubholwa, kulula kakhulu ukuthi i-drill bit incike ohlangothini lwezinto ezithambile. Izixazululo yilezi: okokuqala, sebenzisa i-punch yesampula ukushaya imbobo ohlangothini lwezinto eziqinile ngaphambi kokubholwa; okwesibili, sebenzisa i-drill bit emfushane ukwandisa ukuqina kwe-drill bit ngesikhathi sokubholwa.
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.
● Ukuhlanganiswa kwesihlahla esithwalayo kanye 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.
● 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.
● Ukuklwebha amagobolondo 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 kucindezelwa 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 zokukhuhlwa landa. Lapho isembozo sokuthwala siqinisiwe, ishaft ingajikeleza ngokukhululeka ngaphandle kokuphuma okusobala, futhi amaphuzu okuxhumana ahlangabezana nezidingo, ukukhuhlwa kuyaqedwa.
● Ukulinganiswa kwemvume yokuthwala
Usayizi wesikhala sebheri ungalungiswa yi-gasket esendizeni ephakathi noma ngokuklwebha ngqo isihlahla sebheri. Isikhala sebheri ngokuvamile silinganiswa ngendlela yokucindezela i-lead. Thatha izingxenye eziningana zentambo ye-lead enobubanzi obukhulu kunesikhala sebheri bese uzibeka ku-jenali kanye nendawo ephakathi nendawo yokuhlukana. Bese uqinisa i-nut ukuze ucindezele kahle indawo ephakathi nendawo yokuhlukana, ukhulule i-nut, ususe isembozo sebheri, bese ukhipha ngokucophelela intambo ye-lead eyisicaba. Sebenzisa i-micrometer ukukala ubukhulu besigaba ngasinye esithathiwe. Ngokusekelwe ekujikeni okumaphakathi kwentambo ye-lead, i-clearance yebheri ingaziwa. I-clearance yebheri evamile kufanele ibe ngu-1.5‰-2.5‰ (mm) yobubanzi be-shaft. Uma ububanzi bukhulu, kufanele kuthathwe inani elincane le-clearance. Uma ububanzi be-shaft bungu-60mm, i-cover yebheri 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 zokuhlanganiswa
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.
Uma uhlanganisa 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℃.
