Njira Zosankhira Zinthu Zonyamula Zotsetsereka: Kuyerekeza Magwiridwe Antchito ndi Kusanthula Kugwiritsa Ntchito

Mu kapangidwe ndi kusankha kwamabearing otsetsereka, katundu wa zinthuzo umatsimikiza mwachindunji mphamvu ya katundu wawo, nthawi yogwirira ntchito, komanso kukhazikika kwa ntchito. Ma matrices osiyanasiyana achitsulo amasonyeza kusiyana kwakukulu pakulimba, kukana kutentha, kuyanjana ndi kukangana, komanso kuchepetsa PV (kupanikizika x liwiro), zomwe zimafuna kufananiza molondola kutengera momwe ntchito ikuyendera.

 

Ma alloy a babbitt okhala ndi tin (monga B83/B88)

 

Amadziwika kuti ndi osavuta kuyikamo komanso ogwirizana bwino, amayamwa bwino zinyalala ndikulola kufooka pang'ono kwa shaft. Amakhalanso ndi kukana dzimbiri bwino ndipo ndi oyenera kugwiritsidwa ntchito mwachangu komanso mothamanga, molemera, komanso nthawi zambiri. Komabe, mphamvu zawo zochepa komanso chizolowezi chawo chofewa kutentha kwambiri chimachepetsa kugwiritsidwa ntchito kwawo m'malo othamanga kwambiri kapena kutentha kwambiri.

 

Mkuwa wachitsulo (mtundu wamba: ZCuSn10P1)

 

 

Pokhala ndi mphamvu zambiri zamakanika komanso kukana kuwonongeka, ndi yoyenera kugwiritsidwa ntchito nthawi zonse komanso molimbika. Komabe, malo ake olimba amachititsa kuti ntchito yake isagwire bwino ntchito, imafunika kulondola kwambiri, komanso imapezeka m'malo otentha kwambiri panthawi yogwira ntchito koyamba, zomwe zimafuna kukonzedwa mosamala.

 

Ma alloy opangidwa ndi aluminiyamu (monga AlSn20Cu)

 

Kuchuluka kochepa kumathandiza kuti mapangidwe ake akhale opepuka, komanso kumapereka mphamvu yabwino kwambiri yoyendetsera kutentha komanso kukhazikika kwa kutentha kwambiri, zomwe zimapangitsa kuti zikhale zoyenera kwambiri pakugwira ntchito mwachangu, kutentha kwambiri, komanso mosiyanasiyana. Kapangidwe kake kodzipaka mafuta kamakhala bwino kwambiri mu mabearing akuluakulu a injini zamagalimoto, zomwe zimapangitsa kuti akhale ofunikira kwambiri pakupanga injini zamakono zoyaka mkati.

 

Kuyerekeza Magwiridwe Antchito:

 

Kudzera mu kuyesa kuuma, kusanthula kukhazikika kwa kutentha, ndi kuwunika malire a PV, zitha kuwoneka kuti ngakhale babbitt alloy ndi yofewa, imapereka mgwirizano wamphamvu; bronze imapereka mphamvu zabwino kwambiri zonyamula katundu koma imafuna kuyenerera kolondola; ndipo aluminiyamu-tin alloys imapereka ubwino pakupirira liwiro ndi kutentha, zomwe zimapangitsa kuti magwiridwe antchito awo onse akhale oyenera kwambiri pamikhalidwe yogwira ntchito yosinthasintha komanso yovuta.

 

Kusanthula Mlandu Wogwiritsira Ntchito:

Nchifukwa chiyani mabearing a aluminiyamu-tin alloy amagwiritsidwa ntchito kwambiri mu injini zamagalimoto?

Yankho lake lili mu mphamvu zawo zabwino kwambiri zotopa komanso kuthekera kwawo kochotsa kutentha. Injini imayamba ndi kuyima pafupipafupi, limodzi ndi kugwira ntchito mwachangu, zimapangitsa kuti kutentha kusinthe kwambiri. Zipangizo zopangidwa ndi aluminiyamu sizimangochotsa kutentha mwachangu komanso zimasunga mafuta m'malo mwake ofewa panthawi yopuma kwakanthawi kwa filimu yamafuta, kupewa kugwidwa ndi kufooka komanso kudalirika kwambiri.

 

Kusankhidwa kwachogwiriraZipangizo zimafuna kulinganiza pakati pa zinthu zinayi zofunika: mphamvu yonyamula katundu, kuthamanga, kukana kutentha, ndi moyo. Palibe "zinthu zonse". Pokhapokha pochita kuwunika mwadongosolo kutengera momwe ntchito ikuyendera ndi pomwe pangapezeke kulinganiza bwino pakati pa magwiridwe antchito ndi mtengo.
