Ama-Radial spherical plain bearings

Ama-Radial spherical plain bearings ayizingxenye ezibalulekile ezinhlobonhlobo zezinhlelo zokusebenza zezimboni, ezihlinzeka ngokusekela kwe-pivot kumashafu ajikelezayo nezinye izingxenye ezihambayo. Idizayinelwe ukuthwala imithwalo ye-radial, axial noma ehlanganisiwe, lawa ma-bearings asetshenziswa kakhulu emishinini, ezinhlelweni zezimoto kanye nemishini ye-aerospace. Ukuqonda ukuhlukaniswa kwezigaba zama-radial spherical bearings kubalulekile ekukhetheni uhlobo olulungile lohlelo lokusebenza oluthile kanye nokuqinisekisa ukusebenza okuphelele nempilo yesevisi.

Ukuhlukaniswa kwama-radial spherical bearings

Ama-Radial spherical plain bearings angahlukaniswa ngokusekelwe ezintweni ezimbalwa ezibalulekile, okuhlanganisa ukwakheka kwawo, izinto zokwakha kanye nezici zokusebenza. Ngokuqonda lezi zigaba, onjiniyela nezingcweti zokulungisa bangenza izinqumo ezinolwazi lapho bekhetha ama-bearings ezinhlelo zokusebenza ezahlukene.

1. Ukuhlukaniswa kwemiklamo

Ama-Radial spherical plain bearings ayatholakala ngemiklamo ehlukahlukene ukuze ahlangabezane nezidingo ezahlukene zomthwalo nokunyakaza. Imiklamo evame kakhulu ihlanganisa okulandelayo:

- Insimbi kunsimbi: Lawa mabheringi ahlanganisa iringi yangaphakathi enendawo yangaphandle eyi-convex nendandatho yangaphandle enendawo engaphakathi egobile, yomibili eyenziwe ngensimbi eqinile. Zifanele izinhlelo zokusebenza ezinzima futhi zingamelana nemithwalo esindayo ye-radial kanye nokushaqeka.

- Ithusi Lensimbi: Kulo mklamo, indandatho yangaphakathi yenziwe ngensimbi eqinile, kuyilapho indandatho yangaphandle ifakwe ungqimba lwethusi. Lo mklamo unikeza ukumelana okuhle kokugqoka futhi ulungele izinhlelo zokusebenza ezinemithwalo elinganiselayo nokunyakaza kwe-oscillatory.

- Inhlanganisela yensimbi-PTFE: Iringi yangaphakathi yalawa mabheringi yenziwe ngensimbi eqinile futhi iringi yangaphandle ihlanganiswe ne-PTFE (polytetrafluoroethylene) eyinhlanganisela. Zinikeza ukungqubuzana okuphansi, ukusebenza okungenakulungiswa futhi zilungele izinhlelo zokusebenza lapho ukuthambisa kunzima noma kungenzeki.

- Indwangu yensimbi-ye-PTFE: Ngokufanayo nemiklamo eyinhlanganisela, lawa mabheringi anendandatho yangaphakathi eyenziwe ngensimbi eqinile kanye nendandatho yangaphandle elayishwe ngendwangu ye-PTFE. Zinomthamo omkhulu wokuthwala umthwalo futhi zilungele izinhlelo zokusebenza ezinemithwalo esindayo yama-radial kanye nokugcotshwa okulinganiselwe.

2. Ukuhlukaniswa kwezinto ezibonakalayo

Ama-Radial spherical plain bearings ayatholakala ngenhlanganisela yezinto ezihlukahlukene ukuze afanele izimo zokusebenza ezihlukene kanye nezici zemvelo. Ukukhethwa kwezinto kungathinta kakhulu ukusebenza kokuthwala nempilo yesevisi. Izigaba zezinto ezijwayelekile zihlanganisa:

- Insimbi: Amabhereli emiklamo yensimbi-on-steel noma yensimbi-on-bronze enziwa ngensimbi eqinile ukuze aqine futhi aqine. Izinsimbi zensimbi zifanele izicelo ezinemithwalo esindayo nezimo zokusebenza ezinzima.

- I-PTFE (i-polytetrafluoroethylene): Ama-bearings anenhlanganisela ye-PTFE noma ulayini wendwangu we-PTFE anikeza ukungqubuzana okuphansi, izakhiwo zokuzithambisa kanye nokumelana nokubola nokuguga. Lawa ma-bearings alungele izinhlelo zokusebenza ezidinga ukusebenza okunganakekelwa kanye nempilo yesevisi eyandisiwe.

- Ithusi: Ama-bearings anemigqa yethusi anokumelana okuhle nokugqokwa futhi angakwazi ukumelana nemithwalo emaphakathi nokunyakaza kwe-oscillatory. Zifanele izicelo ezidinga umthamo womthwalo olinganiselayo nokumelana nokugqoka.

3. Ukuhlelwa kokusebenza

Ama-Radial spherical plain bearings nawo ahlukaniswa ngokwezimpawu zawo zokusebenza, okuhlanganisa amandla okuthwala umthwalo, amandla okungahambi kahle kanye nebanga lokushisa lokusebenza. Lezi zigaba zokusebenza zisiza ekukhetheni i-abheri efaneleke kakhulu yohlelo lokusebenza oluthile:

- Umthamo wokuthwala umthwalo: Isilinganiso esiphezulu sokuthwala umthwalo we-radial kanye ne-axial wamabheringi sinquma ukufaneleka kwawo kwezinhlelo zokusebenza ezahlukene. Ama-bearings asebenza kahle kakhulu angakwazi ukumelana nemithwalo esindayo kanye nemithwalo yokushaqeka ngaphandle kokwehluleka ngaphambi kwesikhathi.

- Ikhono lokungaqondani kahle: Amanye ama-bearings aklanyelwe ukuthwala ukungaboni ngasolinye phakathi kweshaft nezindlu, okuvumela ukusebenza kahle ngisho nasezinhlelweni ezinokuchezuka kwe-shaft noma ukungahambi kahle.

- I-Operating Temperature Range: Ama-Bearings alinganiselwe amazinga okushisa aphezulu kanye nobuncane bokusebenza, okuqinisekisa ukusebenza okuthembekile ngaphansi kwezimo zokushisa ezeqisayo.

Ukusetshenziswa kwama-radial spherical bearings

Ama-radial spherical plain bearings asetshenziswa kabanzi ezimbonini nasezinsizeni ezahlukahlukene, kufaka phakathi:

- Imishini: Lawa ma-bearings asetshenziswa emishinini ehlukahlukene efana nemishini yezolimo, imishini yokwakha kanye nemishini yezimboni ukusekela ama-shaft ajikelezayo nezingxenye ezihambayo.

- Amasistimu ezimoto: Ama-Radial spherical plain bearings ayizingxenye ezibalulekile ezinhlelweni zokumiswa kwezimoto, ukuxhumana kokuqondisa nezinye izinhlelo zokusebenza zezimoto ezibalulekile.

- Izisetshenziswa ze-Aerospace: Lawa ma-bearings asetshenziswa egiyeni lokuhlala ezindizeni, izinhlelo zokulawula indiza nezinye izinhlelo zokusebenza zasemkhathini lapho ukusebenza okuphezulu nokwethembeka kubalulekile.
