1. Izidingo zama-bearings anemba ezingxenyeni ezifanayo

Njengoba ukunemba kokunemba kwebheringi ngokwayo kungaphakathi kwe-1 μm, kuyadingeka ukuthi kube nokunemba okuphezulu kobukhulu kanye nokunemba komumo nezingxenye zayo ezihambisanayo (i-shaft, isihlalo esiphethe, ikhava yokugcina, indandatho egcinayo, njll.), ikakhulukazi ukunemba kokukhwelana. indawo engaphezulu kufanele ilawulwe ezingeni elifanayo ne-bearing. Lokhu kubalulekile futhi akunakwa kalula.

Kufanele futhi kuqashelwe ukuthi uma izingxenye ezihambisanayo zebhering enembayo zingahlangabezani nezidingo ezingenhla, ukunemba okunembayo kuvame ukuba nephutha elikhulu ngokuphindwe kaningi kunokuqala ngemuva kokufakwa, noma izikhathi ezingaphezu kweziyi-10 iphutha, futhi akuyona into enembayo nhlobo.Isizathu siwukuthi umshini wokufanisa Iphutha lezingxenye ngokuvamile alimane libekwe phezulu phezu kwephutha lokuthwala, kodwa lingezwe ngemva kokukhuliswa ukuphindaphinda okuhlukene.

2. Ukufakwa kwama-bearings anembayo

Ukuze uqinisekise ukuthi ukuthwala akukhiqizi ukuguqulwa ngokweqile ngemuva kokufakwa, kufanele kwenziwe:

(1) Ukuyindilinga kwe-shaft kanye nembobo yesihlalo kanye nokuma kwehlombe kufanele kudingekile ngokuhambisana nokunemba okuhambisanayo kwe- bear.

(2) Kudingeka ukubala ngokunembile ukuthikamezeka kwefasili ezungezayo kanye nokulingana okufanelekile kwe-ferrule engashintshi.

Ukuphazamiseka kwe-ferrule ejikelezayo kufanele kube kuncane ngangokunokwenzeka.Uma nje umthelela wokwanda okushisayo kumazinga okushisa okusebenza kanye nomthelela wamandla e-centrifugal ngesivinini esiphezulu, ngeke kubangele ukukhasa noma ukushelela kwendawo elingana kahle.Ngokuhambisana nobukhulu bomthwalo wokusebenza kanye nobukhulu bokuthwala, indandatho engaguquki ikhetha ukulingana okuncane kakhulu kwemvume noma ukulingana kokuphazamiseka.Ukuxega kakhulu noma okuminyene kakhulu akusizi ekugcineni umumo wangempela nonembile.

(3) Uma i-bearing isebenza ngaphansi kwezimo zejubane eliphezulu futhi izinga lokushisa liphezulu, kufanele kuqashelwe ngokukhethekile ukulingana kweringi ezungezayo ukuthi ingaxege kakhulu ukuze kuvinjwe ukundindindizela kwe-eccentric, kanye nokulingana kweringi engaguquki ukuvimbela izikhala. kungenzeki.Ikhubaza ngaphansi komthwalo futhi ijabulise ukudlidliza.

(4) Umbandela wokwamukela ukulingana okuncane kokuphazamiseka kwendandatho engaguquki ukuthi izinhlangothi zombili zendawo ehambisanayo zinokunemba komumo ophezulu kanye namahholo amancane, ngaphandle kwalokho kuzokwenza ukufakwa kube nzima futhi ukuqaqa kube nzima kakhulu.Ngaphezu kwalokho, ithonya lokwelulwa okushisayo kwe-spindle lidinga ukucatshangelwa .

(5) Ishafti eyinhloko esebenzisa ipheya yamabhere angama-angular axhunywe kabili ebhola ngokuvamile inomthwalo omncane.Uma ukuphazamiseka kokulingana kukukhulu kakhulu, ukulayisha kuqala kwe-axial kwangaphakathi kuzoba kukhulu kakhulu, kubangele imiphumela emibi.I-shaft eyinhloko esebenzisa ama-double-row short cylindrical roller bearings kanye ne-shaft eyinhloko yama-roller bearings anemithwalo emikhulu, ngakho-ke ukuphazamiseka okufanelekile nakho kukhulu kakhulu.

3. Izindlela Zokuthuthukisa Ukunemba Kwangempela Okufanayo

Ukuze kuthuthukiswe ukunemba kwangempela okufanayo kokufakwa kwebheringi, kuyadingeka ukusebenzisa izindlela zokulinganisa namathuluzi okulinganisa angawohloki i-bearing ukuze kwenziwe ukulinganisa okunembile kobukhulu bobuso obuhambisanayo bembobo engaphakathi kanye nendingilizi yangaphandle yebheringi, futhi ukukalwa kwe-diameter yangaphakathi kanye nobubanzi bangaphandle kungenziwa Zonke izinto ziyalinganiswa, futhi idatha elinganisiwe ihlaziywa ngokugcwele, ngokusekelwe kulokho, izilinganiso zezingxenye zokufaka ezithwala i-shaft kanye nembobo yesihlalo zifaniswa ngokunembile.Uma empeleni ukala izilinganiso ezihambisanayo kanye nokubunjwa kwejometri ye-shaft kanye nembobo yesihlalo, kufanele kwenziwe ngaphansi kwezimo zokushisa ezifanayo njengalapho kulinganiswa ukuthwala.

Ukuze uqinisekise umphumela ophezulu wokufanisa wangempela, ukugoqa kwe-shaft kanye nembobo yezindlu ehambisana nendawo yokuthwala kufanele kube kuncane ngangokunokwenzeka.

Lapho wenza lezi zilinganiso ezingenhla, amasethi amabili amamaki angabonisa isiqondiso sokuphambuka okukhulu kufanele enziwe kumbuthano wangaphandle kanye nomgodi ongaphakathi we-bearing, nasezindaweni ezihambisanayo ze-shaft kanye nembobo yesihlalo, nhlangothi zombili zivale. ku-chamfer yomhlangano, ukuze Emhlanganweni wangempela, ukuchezuka okuphezulu kwamaqembu amabili ahambisanayo kuqondiswe ohlangothini olufanayo, ukuze ngemva komhlangano, ukuphambuka kwamaqembu amabili kususwe kancane.

Inhloso yokwenza amasethi amabili amamaki wokuma ukuthi isinxephezelo sokuchezuka singacatshangwa ngokuningiliziwe, ukuze ukunemba kokuzungezisa okuhambisanayo kweziphetho ezimbili zokusekela kuthuthukiswe, kanye nephutha le-coaxiality lembobo yesihlalo phakathi kwezisekelo ezimbili kanye. amajenali e-shaft kuzo zombili iziphetho atholakala kancane.qeda.Ukusebenzisa izinyathelo zokuqinisa indawo endaweni yokukhwelana, njenge-sandblasting, ukusebenzisa ipulaki enembayo enobubanzi obuthe ukukhudlwana ukuxhuma imbobo engaphakathi kanye, njll., kungasiza ekuthuthukiseni ukunemba kokukhwelana.
