Kukhala ndi chidziwitso chomwe anthu ayenera kudziwa pa injini ya nthunzi!

 

Ma radial bearing a turbine ya nthunzi amagawidwa m'magulu awiri:mabearing a pad okhazikika ndi mabearing a pad opendekeka.

 

1. Chotengera cha pad chokhazikika

 

Ma bearing a pad okhazikika, ma bearing a cylindrical a mafuta, ma bearing a pad ozungulira, ma wedge a mafuta ambiri ndi ma bearing a masamba a mafuta ambiri (osagwiritsidwa ntchito kwambiri pakadali pano).

 

Chotengera chapadera chozungulira, chokhala ndi magawo apamwamba ndi otsika. Bwalo lakunja la thupi lotengera theka la pansi lili ndi mabuloko atatu osinthira ma radial, ndipo pamwamba pa chotengera cha theka lapamwamba pali chotengera cha radial chosinthira ma radial.

 

Ndi yosinthira mabearing.

 

Chotengera cha elliptical ndi chotengera chodziyimira chokha, chomwe chili ndi ubwino wokhala ndi zigawo zochepa mu kapangidwe kake, ndipo babbitt alloy imathiridwa mwachindunji pamwamba pa chotengera, ndipo pamwamba pa chotengera chamkati chimakonzedwa kukhala mawonekedwe a elliptical.

 

2. Kuweramira pad

 

Ma bearing anayi opendekera, kumbuyo kwa theka lapamwamba la ma pad awiriwa, ali ndi ma springs pamalo otulutsira mafuta motsatira chiwongolero, kotero kuti ma pad azikhala ndi nthawi yokankhira ku rotor kumbuyo uku, kuletsa mbali yolowera mafuta ya pad ndi shaft journal kuti isatseke chizolowezi choipa, komanso nthawi yomweyo kukonza malo otsetsereka kumbali yolowera mafuta ya pamwamba pa matailosi, kuti mafuta odzola azitha kulowa bwino pamwamba pa matailosi.

 

Gawo lapamwamba ndi lozungulira, ndipo theka lapansi limapangidwa ndi ma bearing awiri a tilt pad, kukhazikika kwa ma bearing a kapangidwe kameneka ndi kolimba kuposa kwa ma bearing a cylindrical, ndipo mphamvu yobearing ndi yayikulu kuposa ya ma bearing a tilt pad, ndipo ili ndi ubwino wa ma bearing a tilt pad kuti asamawonekere bwino komanso kusasinthasintha bwino pophunzitsa pang'ono.

 

Pakadali pano, mtundu watsopano wa mbali yatsopano ya malo olowera mafuta pamwamba pa matailosi yokhala ndi malo olowera mafuta olowera, mafuta odzola kudzera mu mafuta operekedwa mwachindunji komanso kutulutsa mafuta. Matailosi aliwonse ali ndi malo olowera mafuta, ndipo mafuta odzola amatulutsidwa mwachindunji matailosi akangoyamba kugwira ntchito, omwe amagwiritsa ntchito mphamvu zochepa.

 

Kugawa kwamabearing oponderezedwa

 

1. Mphamvu yolumikizira yozungulira

 

Kapangidwe kameneka kamadziwika ndi ma radial ndi ma thrust bearing omwe amaikidwa m'thupi limodzi, komanso mawonekedwe ozungulira pakati pa thupi lonyamula katundu ndi chikwama chonyamula katundu, kotero kuti bearing imasinthidwa yokha ndi kusintha kwa deflection kwa shaft, kotero kuti pakhale kukhudzana kwabwino pakati pa pamwamba pa pad ndi pamwamba pa thrust plate pa rotor, ndipo kapangidwe kameneka ndi koyenera pa chipangizo chokhala ndi rotor yosinthasintha ndipo axial load si yayikulu kwambiri.

 

Palinso mtundu wa radial thrust combined bearing ya elastic balanced pads, thrust pads imayikidwa pa elastic ring, ndipo elastic ring imapanga elastic deformation ikagwiritsidwa ntchito, kuti ikwaniritse zofunikira kuti pamwamba pa tile iliyonse pakhale bwino ndi thrust plate plane. Kapangidwe kameneka kamagwiritsidwa ntchito m'mayunitsi okhala ndi ma rotor olimba komanso katundu wochepa wa axial.

 

2.Mabearing a Kingsbury

 

Matailosiwo ali ndi chithandizo chofanana ndipo angagwiritsidwe ntchito pa ntchito yowongolera yabwino komanso yoyipa.
