Kuyerekeza pakati pa ma bearing a mpira ndi ma roller bearing
Kusiyana kwakukulu pakati pa Kunyamula mpiraMa s ndi ma roller bearings ndi mawonekedwe ndi momwe chinthu chogudubuza chimagwirira ntchito, zomwe zimakhudza mwachindunji magwiridwe antchito awo ndi momwe amagwiritsidwira ntchito.
Kapangidwe ndi mfundo yogwirira ntchito
Kutengera mpira:
Zinthu zozungulira za chogwirira mpira ndi zozungulira ndipo kukhudzana ndi njira zothamangira mpira kumakhala kolumikizana ndi mfundo. Pamene katundu akuwonjezeka, malo olumikizirana amakhala malo ozungulira, zomwe zimapangitsa kuti mabenki a mpira asamavutike kwambiri komanso kutentha pang'ono akamazungulira pa liwiro lalikulu, oyenera zochitika zozungulira mofulumira kwambiri .
Zinthu zozungulira za chogwirira chozungulira zimakhala ndi mawonekedwe ozungulira kapena ozungulira, ndipo kukhudzana ndi misewu ya raceways kumakhudzana ndi mzere. Malo akuluakulu olumikizirana amatha kufalitsa katundu wambiri, motero mphamvu yonyamulira imakhala yokwera, koma kukana kwakukulu kwa kukangana, koyenera kunyamula katundu wolemera koma liwiro lotsika la kuzungulira .
Makhalidwe a magwiridwe antchito
Kutengera mpira:
Ubwino: Kukangana koyambira kochepa, kukangana koyenera kogwira ntchito, kokhoza kupirira katundu wophatikizana wa radial ndi axial, kosakhudzidwa ndi kusokonezeka kwa mafuta, kosavuta kuyamba kutentha kochepa.
Zoyipa: Kukana kugwedezeka bwino, mtunda waukulu wa radial, zomwe zingayambitse kugwedezeka kwakukulu ndi phokoso.
Zotengera za Roller:
Ubwino: Mphamvu yonyamula katundu, kulondola kwambiri pakugwira ntchito, kapangidwe kakang'ono, mtengo wotsika.
Zoyipa: Kukana kugwedezeka bwino, kuchepa kwa nthawi yogwira ntchito pansi pa liwiro lalikulu komanso katundu wolemera, mphete zamkati ndi zakunja, zovuta kuyika .
Zochitika zogwiritsira ntchito
Maberiya a mpira:
Yoyenera kugwiritsa ntchito zomwe zimafuna liwiro lalikulu, katundu wochepa komanso wosavuta kugwiritsa ntchito, monga ma mota, mafani, ndi zina zotero.
Ma bereji ozungulira:
Yoyenera kugwiritsa ntchito makina othamanga pang'ono, magalimoto akuluakulu kapena magalimoto ogundana, monga makina olemera, magalimoto, sitima, ndi zina zotero.
Yomwe ili ndi mphamvu yonyamula katundu wambiri, ma bearing a mpira kapena ma roller bearing？
Ponena za magwiridwe antchito onyamula katundu, pali kusiyana kwakukulu pakati pa ma roller bearings ndi ma ball bearings. Ma roller bearings, okhala ndi kapangidwe kake kolimba kopangidwa ndi mphete zamkati, mphete zakunja, ma roller ndi ma cages, amasonyeza mphamvu yabwino kwambiri yonyamula katundu. Amagwira ntchito bwino kwambiri pansi pa katundu wolemera kwambiri wa radial ndi katundu wopepuka mpaka wapakati wa radial, zomwe zimapangitsa kuti akhale chisankho chabwino kwambiri cha makina ndi zida zolemera komanso zolemera kwambiri, monga makina olemera, makina omanga ndi ma gearbox akuluakulu. Mosiyana ndi zimenezi, ngakhale kuti ma ball bearings ali ndi kapangidwe kosavuta, kolondola kwambiri komanso kocheperako, mphamvu yawo yonyamula katundu ndi yotsika pang'ono ndipo ndi oyenera kwambiri pamikhalidwe yolemera yapakati. Ma ball bearings amaphatikizapo mitundu yosiyanasiyana monga ma deep groove ball bearings, angular contact ball bearings ndi ma ball bearings odziyimira pawokha, iliyonse yoyenera zida zomwe zili ndi liwiro losiyana ndi zofunikira zonyamula katundu. Chifukwa chake, posankha mtundu wa bearings, kuganizira mokwanira kuyenera kupangidwa kutengera momwe katunduyo alili komanso malo ogwiritsira ntchito zida zamakina. Ma roller bearings ndi oyenera kwambiri kupirira ma radial akuluakulu ndi katundu wolemera, pomwe ma ball bearings amachita bwino pansi pa katundu wochepa.
Kodi ubwino ndi kuipa kwa ma roller bearing ndi ma ball bearing ndi kotani?
Ma roller bearing ndi ma ball bearing ali ndi ubwino ndi kuipa kwawo. Ma roller bearing ali ndi malo akuluakulu olumikizirana ndi mipikisano chifukwa zinthu zozungulira zimakhala zozungulira, zomwe zimawathandiza kupirira katundu wolemera kwambiri wa radial. Alinso ndi kukhazikika bwino komanso kulimba panthawi yogwira ntchito mwachangu, koma coefficient yawo ya friction ndi yayikulu. Zinthu zozungulira za ma ball bearing ndi zozungulira, zokhala ndi coefficient yochepa ya friction komanso ntchito yosinthasintha. Ndizoyenera kugwiritsa ntchito zomwe zimafuna kulondola kwambiri komanso kugwira ntchito mwachangu. Komabe, zikagwiritsidwa ntchito molemera, zimatha kuyambitsa kukhudzana kosakhazikika chifukwa cha mphamvu ya centrifugal. Mtundu wa bearing woti musankhe umatengera momwe mukugwiritsira ntchito komanso zomwe mukufuna.
Ndi iti yomwe ili yoyenera kwambiri pa ntchito yothamanga kwambiri, ma roller bearing kapena ma ball bearing?
Ma roller bearing nthawi zambiri amakhala oyenera kwambiri pa ntchito yothamanga kwambiri. Ma roller bearing ali ndi zinthu zozungulira zozungulira, zomwe zimapangitsa kuti malo olumikizirana ndi mipikisano azitha kugwedezeka kwambiri. Amatha kupirira katundu wolemera komanso kukhala olimba komanso okhazikika bwino panthawi yogwira ntchito yothamanga kwambiri. Zinthu zozungulira za ma ball bearing ndi zozungulira. Ngakhale kuti coefficient of friction ndi yaying'ono, panthawi yogwira ntchito yothamanga kwambiri, kukhudzana pakati pa mipira ndi mipikisano kungakhale kosakhazikika chifukwa cha mphamvu ya centrifugal. Zachidziwikire, kusankha komwe mungagwiritse ntchito bere lomwe liyenera kutsimikiziridwa kutengera momwe mukugwiritsira ntchito komanso zomwe mukufuna.
