Simo Motor Yapambana Kuwunika kwa Dongosolo Loyang'anira Zachilengedwe, Ubwino ndi Ukhondo ndi Chitetezo Pantchito
Mtundu wa zinthu zonyamula katundu umagwira ntchito yofunika kwambiri pakugwira ntchito bwino kwa zinthu zonyamula katundu komanso moyo wake. Kusankha zinthu kumakhudza zinthu monga mphamvu yonyamula katundu, kukangana, kukana kuwonongeka ndi kukana dzimbiri. Pali mitundu yosiyanasiyana ya zinthu zonyamula katundu zomwe zilipo, iliyonse ili ndi makhalidwe ake apadera komanso ntchito zake. M'nkhaniyi, tifufuza mitundu yosiyanasiyana ya zinthu zonyamula katundu, makhalidwe awo, ndi ntchito zomwe zikuyenera kwambiri.
1. Ma beringi achitsulo
Mabeya achitsulo, otchedwanso Maberamu Opanda Chilema, ndi imodzi mwa mitundu yodziwika bwino ya ma bearing. Nthawi zambiri amapangidwa ndi zinthu monga bronze, brass, ndi chitsulo. Mwachitsanzo, ma bearing a bronze amadziwika kuti ndi okhwima kwambiri komanso amatha kupirira katundu wolemera. Ma bearing a bronze ali ndi kukana dzimbiri bwino ndipo ndi oyenera kugwiritsidwa ntchito pamene ma bearing amatha kukhudzidwa ndi chinyezi kapena mankhwala. Ma bearing achitsulo amadziwika kuti ndi amphamvu komanso okhazikika, zomwe zimapangitsa kuti akhale abwino kwambiri pa ntchito zolemera.
Ma bearing apulasitiki akutchuka kwambiri chifukwa cha mphamvu zawo zopepuka, zosagwira dzimbiri komanso zodzipaka zokha. Nthawi zambiri amapangidwa kuchokera ku zipangizo monga polytetrafluoroethylene (PTFE), nayiloni, ndi acetal. Ma bearing a PTFE amadziwika kuti ndi otsika kukangana komanso kukana mankhwala, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pamene ma bearing achitsulo achikhalidwe angalephere. Ma bearing a nayiloni ali ndi kukana kwabwino kwa kuwonongeka ndipo nthawi zambiri amagwiritsidwa ntchito poika zinthu zopepuka. Ma bearing a acetal ndi opirira kwambiri ku chinyezi ndi mankhwala, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito m'malo ovuta.
3. Maberiyani a Ceramic
Ma bearing a Ceramic amadziwika ndi kuuma kwawo kwakukulu, kukana kuvala, komanso kukana dzimbiri. Nthawi zambiri amapangidwa kuchokera ku zinthu monga silicon nitride ndi zirconium oxide. Ma bearing a silicon nitride ali ndi kuuma kwabwino kwambiri komanso kukana kutentha kwambiri, zomwe zimapangitsa kuti akhale abwino kwambiri pakugwiritsa ntchito mwachangu komanso kutentha kwambiri. Ma bearing a Zirconia amadziwika ndi mphamvu zawo zapamwamba komanso kutchinjiriza kutentha, zomwe zimapangitsa kuti akhale oyenera kugwiritsidwa ntchito pomwe ma bearing achitsulo achikhalidwe angalephere.
4. Ma fanizo ophatikizika
Maberiyani opangidwa ndi zinthu zosiyanasiyana, nthawi zambiri amakhala achitsulo kapena pulasitiki olimbikitsidwa ndi ulusi monga graphite, carbon kapena aramid. Maberiyani awa amapereka zinthu zosiyanasiyana monga mphamvu yayikulu, kupsinjika kochepa komanso kukana kuvala bwino. Maberiyani opangidwa ndi zinthu zosiyanasiyana nthawi zambiri amagwiritsidwa ntchito pamene maberiyani achitsulo kapena pulasitiki achikhalidwe angalephere, monga katundu wambiri kapena malo otentha kwambiri.
5. Ma bereji osakanizidwa a Ceramic
Maberiyani a Ceramic hybrid amaphatikiza mphamvu ndi kulimba kwa chitsulo ndi kukana kuwonongeka ndi kukangana kochepa kwa ceramic. Maberiyani awa nthawi zambiri amakhala ndi mipira ya ceramic ndi mpikisano wachitsulo. Amapereka magwiridwe antchito abwino kwambiri pa liwiro lalikulu, kutentha kwambiri komanso malo owononga. Maberiyani a Ceramic hybrid amagwiritsidwa ntchito kwambiri m'mafakitale monga ma motor amagetsi, ma transmission a magalimoto ndi makina amafakitale.
Mwachidule, mtundu wa zinthu zogwirira ntchito umagwira ntchito yofunika kwambiri pakugwira ntchito bwino kwa zinthu zogwirira ntchito komanso kudalirika. Kusankha zinthu kuyenera kutengera mphamvu yonyamula katundu, kukangana, kukana kuwonongeka, kukana dzimbiri ndi zina. Pali mitundu yosiyanasiyana ya zinthu zogwirira ntchito zomwe zilipo, choncho ndikofunikira kusankha zinthu zoyenera pa ntchito iliyonse kuti zitsimikizire kuti zikugwira ntchito bwino komanso nthawi yayitali yogwirira ntchito. Kaya ndi zitsulo, ma pulasitiki, ma ceramic bearing, ma composite bearing kapena ma ceramic hybrid bearing, mtundu uliwonse wa zinthu umapereka zinthu zapadera komanso zabwino pa ntchito zosiyanasiyana. Pomvetsetsa makhalidwe a mtundu uliwonse wa zinthu zogwirira ntchito, mainjiniya ndi opanga amatha kupanga zisankho zodziwa bwino za zinthu zabwino kwambiri pazofunikira zawo zogwirira ntchito.
