Posankha bere, muyenera kuganizira zingapo zofunika.Mfundo yoyamba yofunika kuiganizira ndi katundu amene katunduyo anganyamule.Pali mitundu iwiri ya katundu.
-Axial load: yofanana ndi axis of rotation
-Radial load: perpendicular to axis of rotation
Mtundu uliwonse wa mayendedwe amapangidwa kuti azithandizira katundu wa axial kapena ma radial.Zonyamulira zina zimatha kunyamula mitundu yonse iwiri ya katundu: timazitcha kuti zophatikizana.Mwachitsanzo, ngati katundu wanu akuyenera kunyamula katundu wophatikizidwa, tikukulimbikitsani kuti musankhe chonyamula chodzigudubuza.Ngati mukusowa chonyamulira chomwe chimatha kupirira ma radial okwera kwambiri, tikupangira kuti mukhale ndi cylindrical roller bear.Kumbali ina, ngati mayendedwe anu akufunika kunyamula katundu wopepuka, chonyamulira mpira chikhoza kukhala chokwanira, chifukwa ma fani awa nthawi zambiri amakhala otchipa.
Liwiro la kasinthasintha ndi chinthu chinanso choyenera kuganizira.Ma fani ena amatha kupirira kuthamanga kwambiri.Choncho, mayendedwe cylindrical wodzigudubuza ndi singano wodzigudubuza mayendedwe ndi osayenera ndi apamwamba rotational liwiro poyerekeza mayendedwe popanda osayenera.Komabe, nthawi zina kuthamanga kwambiri kumabwera chifukwa cha katundu.
Muyeneranso kuganizira zopatuka zomwe zingatheke;mayendedwe ena sali oyenera izi, mwachitsanzo mizere iwiri ya mpira.Chifukwa chake, chidwi chiyenera kuperekedwa pakumanga kwa mayendedwe: ma bere otsekeka ndi ma mayendedwe ozungulira amatha kusanja bwino.Tikukulimbikitsani kuti mugwiritse ntchito mayendedwe odzigwirizanitsa nokha kuti musinthe, kuti mukonze zolakwika zomwe zimachitika chifukwa chopindika kapena kukwera kwa shaft.
Apanso, zikhalidwe zogwirira ntchito ndizofunikira kwambiri posankha njira yoyenera.Choncho, m'pofunika kusanthula malo ogwirira ntchito omwe chiberekero chidzagwira ntchito.Mapiritsi anu akhoza kukhala okhudzidwa ndi zowononga zosiyanasiyana.Ntchito zina zimatha kuyambitsa kusokonezeka kwa phokoso, kugwedezeka ndi/kapena kugwedezeka.Chifukwa chake, mayendedwe anu akuyenera kupirira zododometsa izi mbali imodzi osayambitsa zovuta zina.
Mfundo ina yofunika kuiganizira ndiyo kubala moyo.Zinthu zosiyanasiyana, monga kuthamanga kapena kugwiritsa ntchito mobwerezabwereza, zingakhudze moyo wobereka.
Kusankha makina osindikizira ndikofunikira kuti muwonetsetse kuti zonyamula zanu zimagwira ntchito moyenera komanso kwa nthawi yayitali;Choncho, nkofunika kuonetsetsa kuti mayendedwe nthawi zonse amatetezedwa bwino ku zonyansa zilizonse ndi zinthu zakunja monga fumbi, madzi, madzi owononga kapena mafuta ogwiritsidwa ntchito.Kusankha uku kumadalira mtundu wamafuta, momwe chilengedwe chimakhalira (ndiponso pamtundu wa kuipitsidwa), kuthamanga kwamadzimadzi ndi liwiro.
Kuti ndikupatseni poyambira bwino, kuthamanga kwamadzi ndizomwe zimafunikira pakusankha makina osindikizira.Ngati kuthamanga kuli kokwanira (mwachitsanzo mumitundu ya 2-3 bar), chisindikizo chamakina ndi chabwino.Apo ayi, chisankhocho chidzagwirizana mwachindunji ndi mtundu wa mafuta, mafuta kapena mafuta.Mwachitsanzo, pakupaka mafuta, njira zodziwika bwino ndi izi: ma deflectors kapena gaskets, makina opangidwa ndi makina kapena opapatiza okhala ndi grooves;pankhani ya mafuta odzola, makina osindikizira amakhala nthawi zambiri
pamodzi ndi grooves kuti kuchira mafuta.
Mikhalidwe yogwiritsiridwa ntchito idzakhudzanso kusankha kwanu, makamaka pomanga ma beya.Kulingalira kuyeneranso kuganiziridwa pakuumirira ndi kulondola komwe kumafunikira pamene chonyamulira chikugwiritsidwa ntchito.Nthawi zina, preload ingagwiritsidwe ntchito pa msonkhano wonyamula kuti uwonjezere kuuma kwake.Komanso, preload adzakhala ndi zotsatira zabwino pa kubala moyo ndi dongosolo phokoso milingo.Chonde dziwani kuti ngati musankha preload (radial kapena axial), muyenera kudziwa kuuma kwa magawo onse kudzera mu mapulogalamu kapena kuyesa.
Pakati pazosankha zanu, muyeneranso kuganizira zazinthu zoyenera zonyamula.Zovala zimatha kupangidwa ndi chitsulo, pulasitiki kapena ceramic.Zonyamula zimadalira ntchito yomwe ikufuna.Tikukulimbikitsani kuti musankhe chonyamula chomwe sichimamva kupsinjika.Komabe, zinthu zomwe zingagwiritsidwe ntchito zimakhudza mtengo wa bere.
