Kodi kusiyana pakati pa ma bearing otetezedwa ndi ma bearing wamba ndi kotani?

 

Kupatula makhalidwe ndi miyeso yoyambira yaukadaulo,mabearing otetezedwandipo ma bearing wamba amasiyana kwambiri pa mawonekedwe ndi momwe amagwiritsidwira ntchito. Pansipa pali kusanthula kwa kusiyana pakati pa ma bearing otetezedwa ndi ma bearing wamba.

 

Kodi ndi chiyanichonyamulira chotenthetsera?

 

An chonyamulira chotenthetseraamatanthauza chogwirira chomwe chophimba cha ceramic (alumina) chofanana chimapoperedwa pa mphete yamkati kapena yakunja ya chogwirira chamba wamba pogwiritsa ntchito ukadaulo wa plasma spray, kuphatikiza magwiridwe antchito a insulation mu chogwirira. Kapenanso, ma bearing omwe zinthu zake zozungulira zimapangidwa ndi zinthu za ceramic (ma ceramic balls) alinso ndi mphamvu zotetezera, ndipo mitundu yonse iwiri imaonedwa ngati ma bearing otetezedwa.

 

Mabearing ndi zinthu zofunika kwambiri pamakina amakono. Ntchito yawo yayikulu ndikuthandiza ziwalo zamakina ozungulira, kuchepetsa kukangana panthawi yoyenda, ndikuwonetsetsa kuti kuzungulira kuli kolondola.

 

Kapangidwe ka mabearing wamba nthawi zambiri kamakhala ndi: mphete yakunja (nthawi zambiri yopangidwa ndi chitsulo chonyamula), mphete yamkati (nthawi zambiri yopangidwa ndi chitsulo chonyamula), zinthu zozungulira (mipira kapena ma rollers), ndi msonkhano umodzi wa khola.

 

Malinga ndi mtundu wake, akhoza kugawidwa m'magulu awa: ma bearing a mpira wozama kwambiri, ma bearing a mpira wolumikizana ndi angular, ma bearing a cylindrical roller, ma bearing a self-aligning roller (kapena mpira), ma bearing a tapered roller, ndi ena.

 

Mwa ntchito, ma bearing amapangidwira kuti azithandiza, zomwe zikutanthauza kuti amanyamula shaft, koma izi ndi gawo limodzi chabe la ntchito yawo. Kwenikweni, kuthandizira ma bearing kumatanthauza kuti amatha kuthana ndi katundu wa radial. Amathanso kumveka ngati zipangizo zomwe zimagwiritsidwa ntchito kukonza ma shaft, kuchepetsa kuyenda kwawo pomwe akulola kuzungulira. Kusankhidwa kwa ma bearing a QuckEasy Automation kwalembedwa, zomwe zikutanthauza kuti ma bearing amakonza shaft kotero kuti imatha kuzungulira yokha poyang'anira mayendedwe a axial ndi radial.

 

Ma berea otetezedwaAmamangidwa pa mabearing wamba (omwe ali ndi mainchesi ofanana amkati ndi akunja, mphamvu yonyamula katundu, liwiro, ndi kulemera) koma ali ndi wosanjikiza wa zinthu zotetezera zomwe zimayikidwa pa mphete yamkati kapena yakunja ya bearing, zomwe zimapatsa mphamvu zotetezera. Izi zitha kuletsa mphamvu yoyambitsidwa kuti isawononge mphamvu zamagetsi ku bearing ndikuteteza mafuta, zinthu zozungulira, ndi misewu ya raceways kuti zisawonongeke, motero zimakulitsa moyo wa bearing.

 

Kupatula makhalidwe ogwiritsira ntchito, kusiyana pakati pa ziwirizi kumathanso kusiyanitsidwa ndi mawonekedwe awo.

 

Maberiyani wamba nthawi zambiri amakhala ndi mtundu wachitsulo wa chitsulo chonyamula, pomwe maberiyani otetezedwa amakhala ndi mphete zawo zamkati kapena zakunja zokutidwa ndi chosanjikiza choteteza, zomwe zimapangitsa kuti mitundu ikhale yosiyanasiyana. Kawirikawiri, mphete yamkati kapena yakunja imawoneka yakuda, yoyera, kapena imvi.

 

Kuphatikiza apo, kusiyana kumatha kuzindikirika kuchokera ku suffix ya chitsanzo cha bearing.Chotengera chotetezedwaMa model amaimiridwa mofanana ndi ma model wamba, koma amaphatikizapo ma suffix ena owonjezera.
