Momwe mungasankhire mtundu wonyamula

Posankha mtundu wonyamulira, m'pofunika kumvetsetsa bwino mikhalidwe yomwe chifanizirocho chidzagwiritsire ntchito.

Sankhani njira:

1) Malo oyikamo onyamula amatha kukhalamo mumalo oyikapo amtundu wonyamula chifukwa kulimba ndi kulimba kwa shaft kumayankhidwa popanga dongosolo la shaft, kotero kutalika kwa shaft nthawi zambiri kumatsimikiziridwa poyamba, ndiye kuti, mkati. awiri a bere.

Komabe, mayendedwe ogubuduza amabwera mumitundu yosiyanasiyana yamitundu ndi mitundu, ndipo mtundu woyenera kwambiri wonyamulira uyenera kusankhidwa kuchokera kwa iwo.

 

2) Kukula, mayendedwe ndi chikhalidwe cha katundu wonyamula katundu [kuchuluka kwa katundu kumasonyezedwa ndi katundu woyambira, ndipo mtengo wake uli mu tebulo la kukula kwake] Katundu wonyamulira ndi wosiyana, monga kukula kwake. katundu, kaya pali katundu wa radial okha, kaya katundu wa axial ndi unidirectional kapena bidirectional, mlingo wa kugwedezeka kapena kugwedezeka, etc. Pambuyo poganizira zinthu izi, ndi nthawi yosankha mtundu woyenera kwambiri wonyamula.

 

Nthawi zambiri, kuchuluka kwa ma radial kulemedwa kwa mayendedwe omwe ali ndi mayendedwe omwewo kumawonjezeka motere: mayendedwe a mpira wakuya kwambiri < angular contact ball bearings< cylindrical roller bearings< tapered roller bearings< spherical roller bearings

 

3) Mtundu wa kubera womwe liwiro lake lozungulira limatha kutengera liwiro la makina ozungulira [malire a liwiro la kunyamula amawonetsedwa ndi liwiro la malire, ndipo mtengo wake uli mu tebulo la kukula] Liwiro lomaliza la kunyamula sikuli. amangotengedwa kuchokera ku mtundu wobala, komanso wocheperako kukula kwake, mtundu wa khola, mlingo wolondola, zinthu zolemetsa ndi njira zopangira mafuta, etc., kotero zinthuzi ziyenera kuganiziridwa posankha.

 

Zambiri mwazotsatirazi zimagwiritsidwa ntchito pozungulira kwambiri:

Mipira yakuya yakuya, zimbalangondo za mpira, ma cylindrical roller bearings

 

4) Kulondola kwa kasinthasintha: Mtundu wa kunyamula ndi kulondola kozungulira koyenera kwa makina opangira makina, makina opangira mpweya ndi makina owongolera amafunikira kulondola kwapang'onopang'ono, kuthamanga kwambiri komanso kukangana kochepa motsatana, kotero mayendedwe omwe ali ndi kalasi ya 5 kapena kupitilira apo ayenera kugwiritsidwa ntchito.

 

Ma bearings awa nthawi zambiri amagwiritsidwa ntchito:

Mipira yozama ya groove, zimbalangondo za mpira,ma cylindrical roller bearings

 

5) Mtundu wonyamula womwe kulimba kwake kumakumana ndi kukhazikika komwe kumafunikira pakuboola kwamakina M'zigawo monga ma spindles zida zamakina ndi zida zochepetsera zomaliza zamagalimoto, ndikofunikira kuwongolera kulimba kwa shaft ndi kulimba kwa zonyamula.

 

Mapindikidwe a mayendedwe odzigudubuza ndi ocheperapo kuposa mayendedwe a mpira.

 

Kuyika preload (negative clearance) pamayendedwe kumathandizira kuuma. Njira imeneyi ndi yabwino kwa mayendedwe aang'ono kukhudzana mpira ndi mayendedwe tapered wodzigudubuza.

 

6) Unikani kupendekeka kwachibale pakati pa mphete yamkati ndi mphete yakunja (monga kupatuka kwa shaft chifukwa cha katundu, kusalondola bwino kwa shaft ndi chipolopolo kapena cholakwika choyika), ndikusankha mtundu wa kunyamula zomwe zingagwirizane ndi zomwe zimagwiritsidwa ntchito. Ngati kupendekera kwachibale kwa mphete yamkati ku mphete yakunja ndi yaikulu kwambiri, kunyamula kudzawonongeka chifukwa cha katundu wamkati. Chifukwa chake, mtundu wonyamula womwe ungapirire kupendekeka uku uyenera kusankhidwa.

 

Nthawi zambiri, ngodya yovomerezeka (kapena yozungulira) imachulukitsidwa motere:

Ma cylindrical roller bearings, mayendedwe odzigudubuza, mayendedwe a mpira wakuya (makona okhudzana ndi mpira), zozungulira (mpira)

 

7) Pamene pafupipafupi kusonkhana ndi disassembly monga unsembe ndi disassembly kuyendera nthawi ndi kusonkhana ndi disassembly njira pafupipafupi, ndi bwino kugwiritsa ntchito zitsulo cylindrical wodzigudubuza mayendedwe, mayendedwe odzigudubuza singano ndi tapered wodzigudubuza mayendedwe kuti akhoza kulekanitsidwa ndi mphete yamkati ndi mphete yakunja.

 

Mipira yozungulira ndi zozungulira zozungulira zokhala ndi tapered bore zitha kusonkhanitsidwa mosavuta ndi kupasuka pogwiritsa ntchito zomangira kapena manja ochotsa.
