Ma bereji ozungulira ozungulira

Chozungulira chozungulira Maberamu Opanda Chilema Ndi zigawo zofunika kwambiri m'mafakitale osiyanasiyana, zomwe zimathandiza pozungulira ma shaft ozungulira ndi ziwalo zina zosuntha. Ma bearing awa, omwe adapangidwa kuti azinyamula katundu wozungulira, wozungulira kapena wophatikizana, amagwiritsidwa ntchito kwambiri mumakina, makina amagalimoto ndi zida zam'mlengalenga. Kumvetsetsa magulu a ma bearing ozungulira a radial ndikofunikira posankha mtundu woyenera wa ntchito inayake ndikuwonetsetsa kuti magwiridwe antchito abwino komanso moyo wautumiki.

Kugawa ma radial spherical bearing

Ma bearing ozungulira ozungulira amatha kugawidwa m'magulu kutengera zinthu zingapo zofunika, kuphatikizapo kapangidwe kake, zipangizo zake, ndi mawonekedwe ake. Pomvetsetsa magulu awa, mainjiniya ndi akatswiri okonza amatha kupanga zisankho zolondola posankha ma bearing a ntchito zosiyanasiyana.

1. Kugawa mapangidwe

Ma radial spherical plain bearing amapezeka m'mapangidwe osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana zonyamula katundu ndi mayendedwe. Mapangidwe odziwika kwambiri ndi awa:

- Chitsulo pa chitsulo: Ma bearing awa ali ndi mphete yamkati yokhala ndi pamwamba pakunja kozungulira ndi mphete yakunja yokhala ndi pamwamba pamkati kozungulira, zonse zopangidwa ndi chitsulo cholimba. Ndizoyenera kugwiritsidwa ntchito molemera ndipo zimatha kupirira katundu wolemera wa radial ndi shock.

- Chitsulo cha Bronze: Mu kapangidwe kameneka, mphete yamkati imapangidwa ndi chitsulo cholimba, pomwe mphete yakunja ili ndi wosanjikiza wa bronze. Kapangidwe kameneka kamapereka kukana kwabwino kwa kuwonongeka ndipo ndi koyenera kugwiritsidwa ntchito ndi katundu wochepa komanso mayendedwe ozungulira.

- Chitsulo-PTFE composite: Mphete yamkati ya mabearing awa imapangidwa ndi chitsulo cholimba ndipo mphete yakunja ili ndi PTFE (polytetrafluoroethylene) composite. Amapereka kukanda kochepa, ntchito yosakonza ndipo ndi oyenera kugwiritsidwa ntchito pamene mafuta ndi ovuta kapena osagwira ntchito.

- Nsalu ya Chitsulo-PTFE: Mofanana ndi mapangidwe ophatikizika, ma bearing awa ali ndi mphete yamkati yopangidwa ndi chitsulo cholimba ndi mphete yakunja yokhala ndi nsalu ya PTFE. Ali ndi mphamvu zambiri zonyamulira katundu ndipo ndi oyenera kugwiritsidwa ntchito ndi katundu wolemera wa radial komanso mafuta ochepa.

2. Kugawa zinthu

Ma bearing ozungulira ozungulira amapezeka m'mitundu yosiyanasiyana ya zinthu kuti agwirizane ndi mikhalidwe yosiyanasiyana yogwirira ntchito komanso zinthu zachilengedwe. Kusankha zinthu kungakhudze kwambiri magwiridwe antchito a bearing ndi moyo wautumiki. Magulu odziwika bwino a zinthu ndi awa:

- Chitsulo: Maberiyamu opangidwa ndi chitsulo kapena mkuwa amapangidwa ndi chitsulo cholimba kuti akhale olimba komanso olimba.Zitsulo Zopangira Ma Bearing ndi oyenera kugwiritsa ntchito zinthu zolemera komanso zovuta pa ntchito.

- PTFE (polytetrafluoroethylene): Mabearing okhala ndi PTFE composite kapena PTFE fabric lining amapereka mphamvu zochepa zodzipaka mafuta, zodzipaka mafuta okha komanso zotsutsana ndi dzimbiri ndi kuwonongeka. Mabearing awa ndi abwino kwambiri pa ntchito zomwe zimafuna kuti zisamakonzedwe komanso nthawi yayitali yogwira ntchito.

- Bronze: Ma bearing okhala ndi mkuwa ali ndi kukana kutopa bwino ndipo amatha kupirira kutopa pang'ono komanso mayendedwe ozungulira. Ndi oyenera kugwiritsidwa ntchito omwe amafunikira mphamvu yokwanira yonyamula katundu komanso kukana kutopa.

3. Kugawa magwiridwe antchito

Ma bearing ozungulira ozungulira amagawidwanso m'magulu malinga ndi mawonekedwe awo ogwirira ntchito, kuphatikiza mphamvu yonyamula katundu, kuthekera kolakwika kwa kusinthasintha ndi kutentha komwe kumagwiritsidwa ntchito. Magulu a magwiridwe antchito awa amathandiza kusankha bearing yoyenera kwambiri pa ntchito inayake:

- Kutha kunyamula katundu: Kutha kunyamula katundu wozungulira komanso wozungulira kumatsimikiza kuti ndi koyenera kugwiritsidwa ntchito m'njira zosiyanasiyana. Mabearing ogwira ntchito bwino amatha kupirira katundu wolemera komanso katundu wogwedezeka popanda kulephera msanga.

- Kutha Kusakhazikika: Ma bearing ena amapangidwira kuti azitha kukhazikika pakati pa shaft ndi nyumba, zomwe zimathandiza kuti ntchito iyende bwino ngakhale mutakhala ndi vuto la kupotoka kapena kusakhazikika.

- Kuchuluka kwa Kutentha kwa Ntchito: Mabearing amayesedwa kutentha kwakukulu komanso kocheperako kogwira ntchito, zomwe zimawonetsetsa kuti magwiridwe antchito ndi odalirika pansi pa kutentha kwambiri.

Kugwiritsa ntchito ma radial spherical bearing

Ma radial spherical plain bearing amagwiritsidwa ntchito kwambiri m'mafakitale ndi zida zosiyanasiyana, kuphatikizapo:

- Makina: Maberiyani awa amagwiritsidwa ntchito mumakina osiyanasiyana monga zida zaulimi, makina omangira ndi makina amafakitale kuti athandizire ma shaft ozungulira ndi zida zosuntha.

- Makina a magalimoto: Ma radial spherical plain bearing ndi zinthu zofunika kwambiri mu makina oimika magalimoto, ma steering linkages ndi ntchito zina zofunika kwambiri zamagalimoto.

- Zipangizo Zamlengalenga: Maberiyani awa amagwiritsidwa ntchito pa zida zotera ndege, machitidwe owongolera ndege ndi ntchito zina zamlengalenga komwe magwiridwe antchito ndi kudalirika ndizofunikira kwambiri.

Chimatha kupirira katundu wozungulira ndi katundu waung'ono wa axial mbali iliyonse.

(8) GE... Mtundu wa DS: Mphete yakunja ili ndi mbedza yolumikizirana ndi mbedza yolowetsa. Yokhayo ndi ma bearing akuluakulu. Imatha kupirira katundu wozungulira ndi katundu waung'ono wa axial mbali iliyonse (mbali imodzi ya mbedza yolumikizirana singathe kupirira katundu wozungulira).

Mwachidule, kugawa ma radial spherical bearing ndikofunikira kwambiri kuti timvetsetse kapangidwe kake, zipangizo zake, ndi makhalidwe ake. Poganizira magulu awa, mainjiniya ndi akatswiri okonza zinthu amatha kusankha bearing yoyenera kwambiri pa ntchito inayake, kuonetsetsa kuti ikugwira ntchito bwino, ikukhala nthawi yayitali komanso yodalirika. Kaya imathandizira katundu wolemera m'makina amafakitale kapena kupereka ntchito yosalala m'magalimoto ndi m'mlengalenga, ma radial spherical bearing amagwira ntchito yofunika kwambiri pa ntchito zosiyanasiyana, zomwe zimapangitsa kuti ikhale yofunika kwambiri paukadaulo ndi ukadaulo.
