Njengamanje, indandatho yokubulala isetshenziswa kabanzi emikhakheni eminingi.Kodwa abantu abaningi abazi ukuthi bangakhetha kanjani usayizi olungile wendandatho yokushuba.Njengochwepheshei-slewing bearumkhiqizi, thina,I-XZWD Slewing Bearing Co., Ltd, namuhla sizokwethula ngokuningiliziwe indlela yokubalai-slewing bearosayizi.
1.Ijika lomthamo wokuthwala we-slewing bear
Uhlobo ngalunye lwei-slewing bearamasampula omkhiqizo anejika lomthamo ohambisanayo wokuthwala umthwalo, futhi igrafu ingasiza umsebenzisi ukuthi akhethei-slewing bearokwandulelayo.
Kunezinhlobo ezimbili zejika, eyodwa iyijika elimile (①line), umthwalo omkhulu lowoi-slewing bearingabekezelela uma imile.Enye ijika lomkhawulo wokulayisha ibhawudi (8.8, 10.9, 12.9), kunqunywa uma ubude bendawo yebhawodi buphindwe izikhathi ezingu-5 njengobubanzi bebhawodi okuwuphawu, futhi ukulayisha kuqala kungu-70% womkhawulo wesivuno sento yebhawodi.
- 2.Indlela yokubala yokukhetha ibhere yokugwaza
1) Inqubo yokukhetha
Qinisekisa ukuthi umthamo omkhulu we-i-slewing bearingakwazi ukusekela lapho ihlala imile (i-axial load Fa, i-radial load Fr, isikhashana esigingqikayo M).Setha umthwalo omkhulu njengenani lesilinganiso esimile.Inani lesilinganiso esimile kufanele licabangele ubukhulu bomthwalo obukhona esimisweni, okufanele siphethe umthwalo owengeziwe nomthwalo wokuhlola.
Qinisekisa ukuthi i-static security coefficient fs ngokohlobo lwenjini eyinhloko(isimo sohlelo lokusebenza), inani layo lenombolo bheka ithebula 1.
Khetha kuqala uhlobo lwei-slewing bear, qiniseka ukuthi indlela yokubala yomthwalo wereferensi omile u-Fa no-M.
Bala Fa kanye M
Ijika lomkhawulo wokulayisha omile lihambisana nohlobo olukhethiwe lwei-slewing bearphakathi kwamasampula, bese umaka (Faˊ，M ˊ)
Hlola ukuthi iphoyinti lokuxhumanisa (Faˊ，M ˊ) lingaphansi kwejika lomkhawulo omile
Ihlola ukubalwa komthamo wokuthwala ibhawodi (bona lesi sigaba 5.2.4)
2) thayipha ukukhetha ku-static
Indlela yokubala yomthwalo wereferensi omile u-Fa 'no-M'
Indlela I(a=60°)
Isibalo sokukhetha somugqa owodwa webhola lokuthintana lamaphuzu amanei-slewing bearinqubo nge-engeli yokweseka umthwalo ongu-45° no-60° ngokulandelana .
Izindlela I (a = 60 °)
Fa′=(Fa+5.046×Fr)×fs
M′=M×fs
Indlela II(a=45°)
Fa′=(1.225×Fa+2.676×Fr)×fs
M′=1.225×M×fs
Kufomula: Fa '-i-slewing beari-equivalent center axial force (104 N )
M'-i-slewing bearisikhathi esilinganayo sokugumbuqela (N. m)
fs—isici sokuphepha ezimeni zokusebenza ezimile zosekelo lokubulala (bona ithebula 1)
Bese uthola amaphuzu amabili angenhla ejikeni, elinye lawo lingaphansi kwejika.
Uhlobo lwerowu eliwela umugqa owodwa
Fa′=(Fa+2.05×Fr)×fs
M′=M×fs
Uhlobo lwebhola elinemigqa emibili
Isibalo sokukhetha sebhola ledayamitha ehlukene enemigqa emibilii-slewing bear,uma Fr<=10%Fa,ushintsho lwe-engeli yokucindezela ngaphakathi komzila womjaho kumele kubalwe,sicela usithinte mayelana nesibalo sakho.
Fa'= Fa×fs
M′=M×fs
Uhlobo lwerowu lemigqa emithathu
Uma ukhetha irola enemigqa emithathui-slewing bear, bala kuphela ukusebenzisana komthwalo we-axial raceway kanye nesikhathi sokugingqika.
Fa'= Fa×fs
M′=M×fs
2) Ukukhetha okunamandla
Sicela uxhumane nomnyango wethu wezobuchwepheshe ukuze usebenzise ukusebenza okuqhubekayo, ukujikeleza kwesivinini esikhulu nezinye izinhlelo zokusebenza zempilo yesevisi yokusekelwa okujikelezayo.
3) Ihlola ukubalwa komthamo wokuthwala webhawodi
Umthwalo omkhulu (akukho static security factor fs) usetshenziselwa ukulayisha ukusekela okujikelezayo.Hlola ukuthi ingabe umthwalo ungaphansi kwejika lomthwalo olinganiselwe wamabhawudi ebanga adingekayo;
Uma umthamo wokuthwala ibhawudi unganele, singakhethai-slewing bearfuthi noma uthinte umnyango wethu wezobuchwepheshe.
Ifektri ingahlinzeka ngolwazi ngokuya ngesampula yomkhiqizo, isebenzisa ijika lomthamo we-static bearing, ngokuya ngendlela yokubala yohlobo lwe-rotary bearing yokukhetha kokuqala.i-slewing bear, kanye nobuchwepheshe nenkampani yami ukuze siqinisekise.Ingaphinde inikeze ulwazi mayelana ne-rotary bear enkampanini yethu, lapho uqhubeka nokukhetha umklamo wenkampani yami, ngicela ucele 《ithebula lepharamitha elithwala i-rotary 》(kuhlanganise nesijobelelo A nesijobelelo B kuthebula lepharamitha), bese ugcwalisa in, ukuze sikwazi ukuletha kuwe ngokushesha ngangokunokwenzeka uhlelo olunembile lokukhetha oluhambisanayo lwezomnotho nokusebenzayo.
