Makhalidwe a , kodi chogwirira cha gawo loonda n'chiyani?

Ma berengi a gawo loondaali ndi gawo lopyapyala kwambiri lonyamula katundu, lomwe limalola kuti zinthu zisamayende bwino komanso zopepuka, komanso limakulitsa ntchito zosiyanasiyana. Malinga ndi njira zawo zosiyanasiyana zotsekera, mabearing a magawo opyapyala nthawi zambiri amagawidwa m'magulu awa: chisindikizo cha rabara-RS, chisindikizo chachitsulo-ZZ, malo osalala, khadi lachitsulo-K, khadi la mkuwa-M, ndi zina zotero.

 

Kuti mupeze mphamvu yochepa ya kukangana, kulimba kwambiri komanso kulondola kozungulira kwabwino kwamabeya okhala ndi makoma owonda, ma bearing opyapyala amagwiritsa ntchito mipira yachitsulo yokhala ndi mainchesi ang'onoang'ono akunja, ndipo kugwiritsa ntchito ma shaft opanda kanthu kumathandiziranso kuti pakhale malo opepuka komanso olumikizira mawaya. Pofuna kuti bearing igwire ntchito yake bwino, pankhani ya mafuta, ma bearing opyapyala nthawi zambiri amagwiritsa ntchito mafuta opaka ndi mafuta, cholinga chake ndikuchepetsa kukangana kwamkati ndi kuwonongeka kwa bearing, kupewa bearing kuti isatenthe kwambiri, komanso kupewa zinthu zakunja kuti zisalowe mu bearing mkati, kapena kupewa dzimbiri ndi dzimbiri, kuti awonjezere moyo wa bearing. Mukagwiritsa ntchito, pamwamba pa contact contact pamwamba pake pamapaka mafuta bwino, zomwe zimawonjezera moyo; M'malo mwake, ngati mafuta ali otsika ndipo makulidwe a mafuta opaka mafuta si abwino, moyo wake udzafupikitsidwa.

 

Kulondola kofunikira pamabearing a mpira woondandi yayitali kwambiri, chifukwa khoma lake ndi lochepa kwambiri, kotero kulemera kwake nakonso kuli kochepa kwambiri, ndipo kukana kugundana ndi kochepa kwambiri, kotero izi ziyenera kusankhidwa malinga ndi malo ogwiritsira ntchito!

 

Mabeya a mpira okhala ndi makoma owondaIli ndi kapangidwe kosavuta ndipo ndi yosavuta kugwiritsa ntchito. Imagwiritsidwa ntchito makamaka kunyamula katundu wa radial, koma pamene kuwala kwa radial kwa bearing kukuwonjezeka, imakhala ndi magwiridwe antchito ena a angular contact ball bearing, ndipo imatha kupirira katundu wophatikizana wa radial ndi axial. Pamene liwiro lozungulira lili lalikulu ndipo siliyenera kugwiritsa ntchito ma thrust ball bearing, ingagwiritsidwenso ntchito kunyamula katundu wa axial wokha. Poyerekeza ndi mitundu ina ya ma bearing ofanana, mtundu uwu wa bearing uli ndi coefficient yaying'ono yokangana komanso malire a liwiro lalikulu. Komabe, siimakhudzidwa ndi kugwedezeka ndipo si yoyenera kunyamula katundu wolemera. Bearing yofanana ya gawo lochepa ndi mtundu wa bearing yokhala ndi m'lifupi ndi makulidwe apadera a cross-section; Kukula komweko kwa cross-section kumatha kufanana ndi ma bearing ambiri osiyanasiyana amkati; Poyerekeza ndi ma bearing wamba, m'lifupi ndi makulidwe amawonjezeka mofanana ndi kuwonjezeka kwa m'mimba mwake wamkati wa bearing, pomwe ma bearing olingana a gawo lochepa amawonjezera m'mimba mwake wamkati ndikusunga kukula kwa cross-sectional kusasinthika.

 

Kuphatikiza kwa kukula kwa magawo asanu ndi anayi (kuyambira 3/16" mpaka 1") ndi kukula kwa mabowo (kuyambira 1" mpaka 40") kwa gawo lochepa la kuberekera magawo kudzapangitsa kuti pakhale ma bearing ambiri "oonda" okhala ndi magawo ang'onoang'ono ndi mabowo akuluakulu. Zipangizo zoonda zoberekera magawo 52100 chrome steel ndi 440C stainless steel zithanso kukhala zopyapyala za chrome. Mitundu yambiri ikhoza kukhala ndi zomatira kapena zophimba fumbi. Pali mitundu itatu yosiyana ya ma bearing a magawo owonda: ma bearing a mpira wozama, ma bearing a mpira wolumikizana ndi angular, ndi ma bearing a mpira wolumikizana ndi mfundo zinayi. Poyerekeza ndi ma bearing okhazikika, ma bearing a magawo owonda amatha kukonza kapangidwe ka makina bwino kwambiri ndikuchepetsa ndalama zonse. Mitundu itatu yomanga iyi, yophatikizidwa ndi ma rollers osiyanasiyana ndi mitundu yosiyanasiyana ya khola, imalola kupanga mitundu yosiyanasiyana ya zinthu zoonda zoberekera magawo kutengera kukula kochepa kwa magawo. Popeza kukula kwa ma shafts owonda sikusintha ndi kukula kwa mkati, zofunikira pa malo oyika zimakhalabe zomwezo, kulemera kokha kumasintha pang'ono ndi kusintha kwa kukula kwa mkati.

 

Makamaka pazida zachipatala, zida zowunikira, zida zowunikira za infrared, maloboti, ndi zina, malo oyika ndi kulemera ndi zinthu zofunika kuziganizira pankhani ya kapangidwe ndi kupanga konse. Nthawi zambiri, ngakhale mtengo wamsika wa ma bearing a thin-section ndi wapamwamba kuposa ma bearing wamba omwe ali ndi kukula kofanana, ma bearing a thin-section amatha kuchepetsa malo oyika ndi kulemera, zomwe zingayambitse kupulumutsa ndalama zambiri pakupanga ndi kugwiritsa ntchito makina.
