Mabeya a njanji - mawonekedwe a mabeya a gearbox a axle ndi ntchito zake

Ndi chitukuko cha anthu, makampani opanga makina a sitima akupitilizabe kusintha, poyerekeza ndi ukadaulo wopanga ma bearing a sitima ukusinthanso nthawi zonse, momwe ntchito yayikulu ya bearing yozungulira mu gearbox ndikutha kutumiza mphamvu yotulutsa bwino pamene sitima ikuyenda mwachangu, zomwe zikutanthauza kuti iyenera kunyamula katundu wosinthika m'malo ovuta. Mitundu yayikulu ya ma bearing ndi ma bearing ozungulira opendekeka, ma bearing olumikizana anayi ndi ma bearing ozungulira. Makonzedwe a ma bearing amasiyana kutengera kapangidwe ndi momwe bokosi la gear limagwirira ntchito.

 

Mabeya a gearbox a axle

Kugwiritsa ntchito kwakukulu kwa ma bereji a ma gearbox ndi:

Liwiro lalikulu; Yonyamula katundu wambiri; Kugwedezeka ndi kukana kugwedezeka; Kukana kutentha kwambiri.

Kusankha kwa bearing kumatsimikiziridwa malinga ndi kukula kwa gawo loyenera la bokosi la gearbox, poganizira zinthu zomwe zili pamwambapa, ndipo nthawi zambiri zimafuna nthawi yowerengera yopitilira makilomita 2 miliyoni.

 

Kugwiritsa ntchito ma gearbox a axle

1. Ma bereji ozungulira opindika

Maberiyani ozungulira okhala ndi tapered amatha kulekanitsidwa, ndipo gulu lawo lamkati la mphete yozungulira ndi mphete yakunja zimatha kusonkhanitsidwa padera. Kulumikizana kolondola pakati pa zinthu zozungulira ndi msewu wothamanga kumapewa kupsinjika kwa m'mphepete. Maberiyani ozungulira okhala ndi tapered amatha kupirira katundu wautali wa radial ndi axial. Chifukwa maberiyani awa amatha kupirira mphamvu za axial mbali imodzi yokha, amafunika kugwiritsidwa ntchito pophatikiza. Mtundu uwu wa beriyani umagwiritsidwa ntchito m'mabokosi a gearbox ndi mabokosi a axle.

 

2. Kukhudza kolumikizana ndi mfundo zinayi

Ma bearing a mpira wolumikizana ndi mfundo zinayi ndi ma bearing a mpira wolumikizana ndi angular. Amatha kupirira katundu wa axial mbali zonse ziwiri ndipo nthawi zambiri amagwirizanitsidwa ndi ma bearing a cylindrical roller kuti apirire mphamvu za radial, ndi malo olumikizirana a radial. Kapangidwe ka mphete yamkati kamagawanika kamalola kuti ipange mipira yambiri yachitsulo. Ma bearing awa amagwiritsidwa ntchito m'mabokosi a gearbox.

 

3.Mabeya ozungulira a cylindrical

Ma bearing a cylindrical roller bearing a mzere umodzi amagwiritsidwa ntchito kwambiri mu ma bearing a sitima kuposa ma bearing ena chifukwa mphete yamkati imatha kulekanitsidwa ndi gulu lopangidwa ndi mphete yakunja, ma rollers ndi khola, zomwe zimathandiza kwambiri pakuyika, kusokoneza, kukonza ndi kuyang'anira bearing. Ma bearing a cylindrical roller amatha kupirira mphamvu zazikulu za radial, ndipo kulumikizana kolondola pakati pa zinthu zozungulira ndi raceway kumachotsa kupsinjika kwa m'mphepete, ndikuwonjezera kudalirika kwa ntchito zonyamula. Kuphatikiza kwa ma bearing a cylindrical roller bearing a NJ ndi NUP kumatha kupirira mphamvu yokhazikika ya axial. Ma bearing awa amagwiritsidwa ntchito mu ma traction motors, ma gearboxes, ndi ma wheelset hollow shaft drives.

 

4. Ma berea otetezedwa

Pa ntchito zina zoyipa kapena zapadera, shaft bearing ndi motor bearing zitha kuwonongeka chifukwa cha magetsi owonjezera. Ngakhale kuti njira yopangira injini ndi yabwino kwambiri, sizingatheke kupewa kwathunthu kusiyana komwe kungachitike pakati pa rotor ndi stator chifukwa cha asymmetry yamagetsi, kotero mphamvu imadutsa mu bearing ndikupanga closed circuit. Pofuna kupewa zomwe zili pamwambapa, ikani oxide ceramic coating pamwamba pa mphete yakunja ya bearing kuti mutseke magetsi osachepera 1000V, ndikuteteza bearing ku kulephera kwa bearing chifukwa cha kukokoloka kwamagetsi komwe kumachitika chifukwa cha magetsi owonjezera.
