Kodi mafakitale ogwiritsira ntchito mitundu yeniyeni ya mabearing ndi ati?
Ma bearings a mitundu yosiyanasiyana amagwiritsidwa ntchito kwambiri m'magawo osiyanasiyana amafakitale chifukwa cha mawonekedwe awo komanso kusiyana kwa magwiridwe antchito. Fotokozani momwe amagwiritsidwira ntchito nthawi zambiri pamodzi ndi magulu a mitundu:
- mlatho wozama Maberamu a Mpira
- mitundu yaying'ono (monga 606):
Ma spindle a zipangizo zapakhomo, ma rotor ang'onoang'ono a injini, zida zolondola.
- Mndandanda wamba (monga 6000, 6002):
Jenereta ya galimoto, pampu yamadzi, zida zamagetsi (chobowolera chamagetsi, chopukusira cha Angle).
- mitundu yayikulu ya mphete yamkati (monga 6204, 6304):
Mafani a mafakitale, lamba wonyamulira chozunguliras, ma gearbox a makina a zaulimi.
- ma bereji ozungulira opindika
- mitundu yaying'ono ndi yapakatikati (monga 30205):
Mawilo agalimoto, magiya opatsira magiya, ma spindles a zida zamakina.
- kukula kwa arge (monga 30310):
Makina omangira (gudumu la track worker), shaft yayikulu ya mine crusher, differential ya lori lolemera.
3. Mabeya ozungulira a cylindrical (NN/NU series)
- NN3020K (mizere iwiri):
Chopondera cha chida cha makina, chozungulira cha mota chothamanga kwambiri, khosi lozungulira bwino la mphero.
- Mndandanda wa TSOPANO:
Thandizo lalikulu la stator ya mota, bokosi la axle yoyendera njanji .
Malamulo akuluakulu ogawa mafakitale:
1. Makampani a magalimoto (omwe ali ndi 43%)
Ma Hub bearing (ma tapered roller bearing), ma generator bearing (ma deep groove ball bearing), ma gearbox bearing (ma angler contact ball bearing)
2. Mphamvu ndi mafakitale olemera
Shaft yaikulu ya turbine ya mphepo (ma bereji odziyendetsa okha), chipangizo chamagetsi cha kutentha (ma bereji ozungulira a cylindrical)
3. Zipangizo zapamwamba kwambiri
Shaft yayikulu ya injini ya ndege (mabearing a mpira wa ceramic), gearbox ya sitima yothamanga kwambiri (mabearing olondola kwambiri).
Malangizo osankha: Ma bearing a mtundu womwewo angagwiritsidwe ntchito m'njira zosiyanasiyana chifukwa cha ma grade awo olondola (P5/P4). Mwachitsanzo, ma spindles a zida zamakina amafunika ma bearing olondola a P4 grade kapena kupitirira apo. Ma bearing amphamvu a mphepo amafunika kapangidwe kapadera kotsutsana ndi dzimbiri komanso moyo wautumiki . Kuti mudziwe magawo enaake a chitsanzo, chonde onani buku laukadaulo la wopanga.
Zofunikira zazikulu pakugwira ntchito kwa bere zimasiyana kwambiri m'mafakitale osiyanasiyana, makamaka kuyang'ana kwambiri miyeso monga kulondola, liwiro lozungulira, mphamvu yonyamula katundu, komanso kusinthasintha kwa chilengedwe.
Makampani a magalimoto
1. Mabearing a injini atsopano oyendetsera mphamvu: Ayenera kukhala ndi liwiro lalikulu (dm•n value ≥ 70,000 mm·r/min), kukana kutentha kwambiri (> 150℃), komanso kukana kugwedezeka kwa ma frequency ambiri. Zipangizozo ziyenera kukhala zokhazikika kwambiri, ndipo makina odzola mafuta ayenera kusintha kuti agwirizane ndi zovuta zogwirira ntchito za injini.
1. Mabeyala a injini achikhalidwe: Mabeyala a tensioner pulley ndi idler pulley ayenera kukhala olimba kwambiri komanso opanda phokoso kuti akwaniritse zofunikira zotumizira bwino motsatira njira yosungira mphamvu ya injini.
- Chotengera cha Hub: Ma bereki ozungulira okhala ndi tapered amafunika kupirira katundu wovuta mbali zonse ziwiri pamene akukwaniritsa zofunikira za kapangidwe kopepuka komanso ka nthawi yayitali (monga makilomita opitilira 1 miliyoni).
Ndege
1. Malire olondola: Kulekerera kwa mabearing a injini ya aero kuyenera kukhala ≤0.005 millimeters (5 microns), ndipo mitundu yankhondo imafunikiranso kulondola kwa 0.1 microns .
- Kulekerera kwambiri zachilengedwe:
- Ma bearing amlengalenga ayenera kukhala opirira kutentha kwambiri komanso kotsika (-180℃ mpaka 300℃), kuwala kwa dzuwa komanso kukhala ndi mpweya wochepa.
- Konzani vuto la mafuta opaka vacuum pogwiritsa ntchito zipangizo zadothi kapena mafuta opaka perfluoropolyether (PFPE).
- Kudalirika: Kulephera kulephera 20,000 revolutions pa mphindi).
Mphamvu ndi Makampani Olemera
1. Chotengera chachikulu cha shaft cha turbine ya mphepo:
Mabeya odziyendetsa okha amafunika kupirira kusinthasintha kwamphamvu kwa mphamvu ya mphepo ndi nthawi yopatuka, ndipo chophimba chotsutsana ndi dzimbiri chiyenera kupangidwira malo opopera mchere.
Moyo wa kapangidwe > zaka 20, nthawi yokonza ≥ zaka 5 .
2. Zipangizo zamagetsi/zamagetsi amadzi:
Mabeyala ozungulira a cylindrical amakhala ndi matani mazana ambiri ndipo amagwiritsidwa ntchito limodzi ndi makina oziziritsira akunja kuti azitha kulamulira kutentha.
Maginito apadera achitsulo (monga chitsulo cha M50) amasankhidwa m'malo otentha kwambiri.
