Nchifukwa chiyani ma bearing a mpira ndi abwino kuposa ma roller bearing?

Mabearing ndi zinthu zofunika kwambiri pa makina ndi zida zambiri chifukwa amachepetsa kukangana ndipo amalola kuyenda bwino kwa ziwalo zozungulira ndi zobwerezabwereza. Pali magulu awiri akuluakulu a mabearing: mabearing a mpira ndi mabearing ozungulira. Amabwera m'mawonekedwe osiyanasiyana, kukula ndi makhalidwe, oyenera kugwiritsidwa ntchito mosiyanasiyana.

Maberiya a mpira amagwiritsa ntchito mipira yodziyimilira yokha ngati zinthu zozungulira, pomwe maberiya a roller amagwiritsa ntchito ma roll a cylindrical, conical kapena spherical. Kusiyana kwakukulu pakati pawo ndi malo olumikizirana pakati pa zinthu zozungulira ndi mphete. Maberiya a mpira ndi malo olumikizirana, zomwe zikutanthauza kuti malo olumikizirana ndi ochepa kwambiri. Maberiya a roller ali ndi mzere wolumikizirana, zomwe zikutanthauza kuti malo olumikizirana ndi akulu.

Malo olumikizirana amakhudza magwiridwe antchito a mabearing ndi magwiridwe antchito. Mabearing a mpira ali ndi kukangana kochepa komanso kukana, zomwe zikutanthauza kuti amatha kugwira ntchito pa liwiro lalikulu komanso kutentha kochepa. Mabearing a roller ali ndi mphamvu yayikulu yonyamula katundu komanso kukana kugwedezeka, zomwe zikutanthauza kuti amatha kupirira kugwedezeka kolemera komanso kwakukulu.

Chifukwa chake, ma bearing a mpira ndi abwino kuposa ma roller bearing pazinthu zina, monga:

• Liwiro: Ma bearing a mpira amatha kukhala ndi liwiro lozungulira kwambiri kuposa ma bearing a roller chifukwa amakhala ndi kukangana kochepa komanso kusakhala ndi mphamvu zambiri.

• Phokoso: Ma bearing a mpira sapanga phokoso lochepa komanso kugwedezeka pang'ono kuposa ma bearing a roller chifukwa mayendedwe awo ndi osalala komanso olondola kwambiri.

• Kulemera: Ma bearing a mpira ndi opepuka kuposa ma roller bearing chifukwa ma bearing a mpira ali ndi zinthu zochepa komanso zazing'ono zozungulira.

• Mtengo: Ma bearing a mpira ndi otsika mtengo kuposa ma roller bearing chifukwa kapangidwe kake ndi kapangidwe kake ndi kosavuta komanso kofanana.

Komabe, ma bearing a mpira nthawi zambiri samakhala abwino kuposa ma bearing a roller. Ma bearing a roller ali ndi zabwino zake, monga:

• Kukweza: Ma roller bearing amatha kuthana ndi katundu wolemera kwambiri wa radial ndi axial kuposa ma ball bearing chifukwa ali ndi malo olumikizirana akuluakulu komanso kugawa bwino katundu.

• Kuuma: Ma roller bearing ndi olimba komanso okhazikika kuposa ma ball bearing chifukwa amasinthasintha ndikupotoza pang'ono akamalemera.

• Kulinganiza: Ma roller bearing amatha kulola kusokonekera ndi kupatuka kwa shaft ndi housing chifukwa ali ndi mawonekedwe odzilinganiza okha.

Mwachidule, ma bearing a mpira ndi ma roller bearing ali ndi ubwino ndi kuipa kosiyana, ndipo kusankha bearing kumadalira zofunikira ndi mikhalidwe yeniyeni ya ntchitoyo.
