Ma Radial spherical plain bearings

Ma radial spherical plain bearings ndi gawo lofunikira pamafakitale osiyanasiyana, kupereka chithandizo cha pivot pamiyendo yozungulira ndi magawo ena osuntha. Amapangidwa kuti azinyamula katundu wa radial, axial kapena kuphatikiza, zonyamula izi zimagwiritsidwa ntchito kwambiri pamakina, makina amagalimoto ndi zida zamlengalenga. Kumvetsetsa kagayidwe ka ma radial spherical bearings ndikofunikira kuti musankhe mtundu wolondola wa pulogalamu inayake ndikuwonetsetsa kuti magwiridwe antchito ndi moyo wabwinobwino.

Gulu la ma radial spherical bearings

Ma Radial spherical plain bearings amatha kugawidwa kutengera zinthu zingapo zofunika, kuphatikiza kapangidwe kake, zida ndi magwiridwe antchito. Pomvetsetsa maguluwa, mainjiniya ndi akatswiri okonza zinthu amatha kupanga zisankho zodziwika bwino posankha ma bearing a ntchito zosiyanasiyana.

1. Gulu la mapangidwe

Ma Radial spherical plain bearings amapezeka m'mapangidwe osiyanasiyana kuti akwaniritse zofunikira zosiyanasiyana komanso zoyenda. Mapangidwe odziwika kwambiri ndi awa:

- Chitsulo pazitsulo: Ma bere awa amakhala ndi mphete yamkati yokhala ndi mawonekedwe owoneka bwino komanso mphete yakunja yokhala ndi chitsulo chopindika, zonse zopangidwa ndi chitsulo cholimba. Iwo ndi oyenera ntchito zolemetsa ndipo amatha kupirira zolemetsa zolemetsa komanso zowopsa.

- Mkuwa wachitsulo: Pamapangidwe awa, mphete yamkati imapangidwa ndi chitsulo cholimba, pamene mphete yakunja imakhala ndi mkuwa. Kapangidwe kameneka kamapereka kukana kwabwino kovala ndipo ndi koyenera kugwiritsa ntchito zolemetsa zolimbitsa thupi komanso kuyenda kwa oscillatory.

- Chitsulo-PTFE chophatikizika: Mphete yamkati ya zitsulozi imapangidwa ndi chitsulo cholimba ndipo mphete yakunja imakhala ndi PTFE (polytetrafluoroethylene) yopangidwa. Amapereka kukangana kochepa, kopanda kukonza ndipo ndi koyenera kugwiritsa ntchito komwe kuthira kumakhala kovuta kapena kosatheka.

- Nsalu za Steel-PTFE: Zofanana ndi mapangidwe ophatikizika, ma bere awa ali ndi mphete yamkati yopangidwa ndi chitsulo cholimba komanso mphete yakunja yokhala ndi nsalu ya PTFE. Ali ndi katundu wonyamula katundu wambiri ndipo ndi oyenera kugwiritsa ntchito zolemetsa zolemetsa komanso mafuta ochepa.

2. Gulu lazinthu

Ma Radial spherical plain bearings amapezeka mumitundu yosiyanasiyana kuti agwirizane ndi magwiridwe antchito komanso zachilengedwe. Kusankhidwa kwa zinthu kungakhudze kwambiri kubereka komanso moyo wautumiki. Magulu azinthu zodziwika bwino ndi awa:

- Chitsulo: Ma bearings muzitsulo-pa-zitsulo kapena zitsulo-pa-bronze mapangidwe amapangidwa kuchokera ku zitsulo zolimba kuti zikhale zolimba komanso zolimba. Zonyamula zitsulo ndizoyenera kugwiritsa ntchito zolemetsa zolemetsa komanso zovuta zogwirira ntchito.

- PTFE (polytetrafluoroethylene): Ma bearings okhala ndi PTFE composite kapena PTFE nsalu zomangira zimapereka mikangano yotsika, zodzitchinjiriza zokha komanso kukana dzimbiri ndi kuvala. Ma bearings awa ndi abwino kwa mapulogalamu omwe amafunikira ntchito yopanda kukonzanso komanso moyo wautali wautumiki.

- Bronze: Ma bere okhala ndi mkuwa ali ndi kukana kovala bwino ndipo amatha kupirira katundu wocheperako komanso mayendedwe ozungulira. Iwo ndi oyenera ntchito amafuna moyenera katundu mphamvu ndi kuvala kukana.

3. Gulu la magwiridwe antchito

Ma Radial spherical plain bearings amagawidwanso molingana ndi momwe amagwirira ntchito, kuphatikiza mphamvu yonyamula katundu, kuthekera kolakwika komanso kutentha kwa magwiridwe antchito. Magulu a magwiridwe antchitowa amathandizira pakusankha koyenera kwambiri kwa pulogalamu inayake:

- Mphamvu yonyamula katundu: Kuchuluka kwa ma radial ndi axial katundu wonyamula katundu kumatsimikizira kuyenerera kwawo kugwiritsa ntchito zosiyanasiyana. Miyendo yogwira ntchito kwambiri imatha kupirira katundu wolemetsa komanso kugwedezeka popanda kulephera msanga.

- Kuthekera Kolakwika: Ma bereti ena amapangidwa kuti agwirizane molakwika pakati pa shaft ndi nyumba, kulola kugwira ntchito bwino ngakhale pamapulogalamu omwe amapatuka kapena kusanja bwino.

- Operating Temperature Range: Bearings amavotera kutentha kwakukulu komanso kochepa kwambiri, kuonetsetsa kuti ntchito yodalirika ikugwira ntchito pansi pa kutentha kwambiri.

Kugwiritsa ntchito ma radial spherical bearings

Ma Radial spherical plain bearings amagwiritsidwa ntchito kwambiri m'mafakitale ndi zida zosiyanasiyana, kuphatikiza:

- Makina: Ma bere awa amagwiritsidwa ntchito pamakina osiyanasiyana monga zida zaulimi, makina omanga ndi makina am'mafakitale kuti athandizire ma shaft ozungulira ndi magawo osuntha.

- Makina amagalimoto: Ma Radial spherical plain bearings ndi gawo lofunikira pamakina oyimitsa magalimoto, maulalo owongolera ndi zina zofunika kwambiri zamagalimoto.

- Zipangizo Zam'mlengalenga: Ma bere awa amagwiritsidwa ntchito pazida zoikira ndege, makina owongolera ndege ndi zida zina zakuthambo pomwe magwiridwe antchito apamwamba komanso kudalirika ndikofunikira.

Imatha kupirira katundu wa radial ndi katundu wochepa wa axial mbali iliyonse.

(8) GE... DS mtundu: Mphete yakunja ili ndi poyambira komanso poyambira mafuta. Zochepa ku ma bearings akuluakulu. Ikhoza kupirira katundu wa radial ndi katundu wochepa wa axial kumbali zonse (mbali imodzi ya groove ya msonkhano sungathe kupirira katundu wa axial).

Mwachidule, kugawidwa kwa ma radial spherical bearings ndikofunikira kuti timvetsetse kapangidwe kawo, zida ndi magwiridwe antchito. Poganizira zamaguluwa, mainjiniya ndi akatswiri okonza zinthu amatha kusankha zoyenera kwambiri pakugwiritsa ntchito inayake, kuwonetsetsa kuti magwiridwe antchito abwino, kukhala ndi moyo wautali komanso kudalirika. Kaya amathandizira katundu wolemetsa wamakina am'mafakitale kapena kupereka magwiridwe antchito bwino pamagalimoto am'mlengalenga ndi ndege, ma radial spherical bearings amatenga gawo lofunikira pamagwiritsidwe osiyanasiyana, kuwapangitsa kukhala ofunikira muukadaulo ndiukadaulo. s gawo.
