Pali zinthu zingapo posankha mtundu wodzigudubuza

Kunyamula monga gawo lalikulu la zida zamakina, pogwira ntchito kumagwira ntchito yofunika kwambiri, kotero ife pakusankha mtundu wodzigudubuza ndi mfundo yofunika kwambiri,Mtengo wa CWLangakuuzeni momwe tingapezere bwino mtundu woyenera kwambiri wa kubala posankha mtundu wa kupiringa, kudzera muzinthu izi kusankha mtundu wa kupiringa.

 

Kusankha mtundu woyenera wakugudubuza kubereka, onani zinthu zazikulu izi:

1. Katundu mikhalidwe

Kukula, mayendedwe ndi chikhalidwe cha katundu pa chonyamulira ndi maziko aakulu kusankha kubala mtundu. Ngati katunduyo ndi wochepa komanso wokhazikika, mayendedwe a mpira ndi osankha; Pamene katunduyo ndi waukulu ndipo pali chikoka, ndi bwino kusankha mayendedwe odzigudubuza; Ngati chonyamuliracho chimangotengera kuchuluka kwa ma radial, sankhani mpira wokhala ndi ma radial contact kapena cylindrical roller bear; Pamene katundu wa axial yekha walandiridwa, choponderetsa chiyenera kusankhidwa; Pamene kunyamula kumayikidwa pazitsulo zonse za radial ndi axial, ma bereti okhudzana ndi angular amasankhidwa. Kukula kwa axial katundu, ndikokulirapo koyenera kolumikizana kuyenera kusankhidwa, ndipo ngati kuli kofunikira, kuphatikiza kwa ma radial ndi thrust bear kungasankhidwe. Tiyenera kuzindikira kuti mayendedwe oponderezedwa sangathe kupirira katundu wa radial, ndipo ma cylindrical roller bearings sangathe kupirira katundu wa axial.

 

2. Liwiro la kunyamula

Ngati kukula kwake ndi kulondola kwa kunyamula kuli kofanana, kuthamanga kwakukulu kwa mpira kumakhala kopambana kuposa kunyamula kwa roller, kotero pamene liwiro liri lalitali ndipo kulondola kozungulira kumafunika kukhala apamwamba, mpirawo uyenera kusankhidwa. .

 

Ma thrust bearingskukhala ndi ma liwiro otsika oletsa. Liwiro logwira ntchito likakhala lalitali ndipo katundu wa axial sakhala wamkulu, mayendedwe a mpira ozungulira kapena mayendedwe a mpira wakuya angagwiritsidwe ntchito. Kwa mayendedwe othamanga kwambiri, kuti muchepetse mphamvu ya centrifugal yogwiritsidwa ntchito ndi zinthu zogubuduza panjira yakunja ya mphete, ndikofunikira kusankha ma bere okhala ndi mainchesi ang'onoang'ono akunja ndi mainchesi ozungulira. Kawirikawiri, ziyenera kutsimikiziridwa kuti kubereka kumagwira ntchito pansi pa liwiro la malire. Ngati liwiro logwira ntchito likuposa liwiro la malire, zofunikira zimatha kukumana ndi kuonjezera mlingo wa kulekerera kwa kubereka ndikuwonjezera moyenerera chilolezo chake cha radial.

 

3. Kudzigwirizanitsa ntchito

Mbali yochepetsera pakati pa axis ya mkati ndi kunja kwa mphete iyenera kuyang'aniridwa mkati mwa mtengo wa malire, mwinamwake katundu wowonjezera wa kunyamula adzawonjezeka ndipo moyo wake wautumiki udzachepetsedwa. Kwa dongosolo la shaft lomwe lili ndi kuuma kovutirapo kapena kuyika kosakwanira bwino, njira yopatuka pakati pa olamulira amkati ndi akunja a mphete ndi yayikulu, ndipo m'pofunika kusankha chotengera chokhazikika. Mongazodzikongoletsera za mpira(kalasi 1), zodzikongoletsera zodzigudubuza (kalasi 2), etc.

 

4. Malo ovomerezeka

Pamene kukula kwa axial kuli kochepa, ndi bwino kusankha mayendedwe opapatiza kapena owonjezera. Pamene kukula kwa radial kuli kochepa, ndibwino kuti musankhe kubereka ndi zinthu zazing'ono zogudubuza. Ngati kukula kwa radial kuli kochepa ndipo katundu wa radial ndi wamkulu,singano wodzigudubuza mayendedweakhoza kusankhidwa.

 

5. Kusonkhana ndi kusintha ntchito

Mphete zamkati ndi zakunja zatapered wodzigudubuza mayendedwe(Kalasi 3) ndima cylindrical roller bearings(Kalasi N) ikhoza kulekanitsidwa, kupangitsa kukhala kosavuta kusonkhanitsa ndi kusokoneza.

 

6. Chuma

Pankhani yokwaniritsa zofunikira zogwiritsira ntchito, zotengera zotsika mtengo ziyenera kusankhidwa momwe zingathere. Nthawi zambiri, mtengo wa mayendedwe a mpira ndi wotsika kuposa wa mayendedwe odzigudubuza. Kukwera kwa kalasi yolondola ya bearing, kumakwera mtengo wake.

Ngati palibe zofunikira zapadera, mayendedwe olondola wamba ayenera kusankhidwa momwe angathere, ndipo pokhapokha ngati pali zofunikira zapamwamba za kulondola kwa kasinthasintha, mayendedwe apamwamba ayenera kusankhidwa.

 

Kugudubuza kunyamula ndi chinthu chodziwika bwino cha makina, mitundu yake yopukutira nayonso ndi yambiri, mitundu yosiyanasiyana ya ntchito ndi yotakata, koma titha kusankha chonyamulira choyenera kwambiri malinga ndi mikhalidwe ndi zofunikira, kuti tipititse patsogolo bwino. ntchito yopangira zida zamakina.
