Kodi ukadaulo wa bearing ukusintha bwanji?

M'zaka makumi angapo zapitazi, kapangidwe ka ma bearing kapita patsogolo kwambiri pobweretsa kugwiritsa ntchito zinthu zatsopano, njira zamakono zopaka mafuta komanso kusanthula kwapamwamba kwa makompyuta..

Mabearing amagwiritsidwa ntchito pafupifupi m'makina onse ozungulira. Kuyambira zida zodzitetezera ndi zoyendera ndege mpaka kupanga chakudya ndi zakumwa, kufunikira kwa zinthuzi kukukwera. Chofunika kwambiri, mainjiniya opanga mapulani akufuna mayankho ang'onoang'ono, opepuka komanso olimba kuti akwaniritse ngakhale mayeso oyesa kwambiri a chilengedwe.

 

Sayansi ya zipangizo

Kuchepetsa kukangana ndi gawo lofunika kwambiri pa kafukufuku wa opanga. Zinthu zambiri zimakhudza kukangana monga kulekerera kwa miyeso, kutha kwa pamwamba, kutentha, katundu wogwirira ntchito ndi liwiro. Kupita patsogolo kwakukulu kwachitika mu chitsulo chonyamula zitsulo kwa zaka zambiri. Zitsulo zamakono zonyamula zitsulo zoyera kwambiri zili ndi tinthu tating'onoting'ono tosakhala chitsulo, zomwe zimapangitsa kuti ma bearing a mpira azilimba kwambiri kutopa.

 

Njira zamakono zopangira ndi kuchotsa mpweya wa gasi zimapanga chitsulo chokhala ndi ma oxides ochepa, sulfides ndi mpweya wina wosungunuka pomwe njira zabwino zolimbitsira zimapanga zitsulo zolimba komanso zosatha. Kupita patsogolo kwa makina opangira zinthu kumathandiza opanga ma bearing olondola kukhalabe ndi kulekerera kwabwino mu zigawo za bearing ndikupanga malo olumikizirana opukutidwa bwino, zonse zomwe zimachepetsa kukangana ndikuwonjezera moyo.

 

Zitsulo zatsopano zosapanga dzimbiri za 400-grade (X65Cr13) zapangidwa kuti ziwongolere kuchuluka kwa phokoso la ma bearing komanso zitsulo zambiri za nayitrogeni kuti ziteteze dzimbiri kwambiri. Pamalo omwe amawononga kwambiri kapena kutentha kwambiri, makasitomala tsopano amatha kusankha kuchokera ku mitundu yosiyanasiyana ya ma bearing a 316-grade stainless steel, ma bearing a ceramic full kapena ma bearing apulasitiki opangidwa kuchokera ku acetal resin, PEEK, PVDF kapena PTFE. Pamene kusindikiza kwa 3D kukugwiritsidwa ntchito kwambiri, komanso chifukwa chake kumakhala kotsika mtengo, tikuwona mwayi wowonjezereka wopanga ma bearing retainers osakhazikika pang'ono, chinthu chomwe chidzakhala chothandiza pazosowa zochepa za ma bearing apadera.

 

Kupaka mafuta

 

Kupaka mafuta mwina ndiko kwakopa chidwi chachikulu. Popeza 13% ya kulephera kwa ma bearing kumachitika chifukwa cha zinthu zopaka mafuta, mafuta opaka mafuta ndi gawo lofufuza lomwe likusintha mwachangu, lothandizidwa ndi akatswiri ndi mafakitale. Tsopano pali mafuta ambiri apadera chifukwa cha zinthu zingapo: mitundu yosiyanasiyana ya mafuta opangidwa apamwamba, kusankha kwakukulu kwa zokhuthala zomwe zimagwiritsidwa ntchito popanga mafuta ndi mitundu yambiri ya zowonjezera mafuta kuti apereke, mwachitsanzo, mphamvu zambiri zonyamula katundu kapena kukana dzimbiri kwambiri. Makasitomala amatha kusankha mafuta osefedwa kwambiri okhala ndi phokoso lotsika, mafuta othamanga kwambiri, mafuta opaka kutentha kwambiri, mafuta osalowa madzi komanso osagwira mankhwala, mafuta opaka utsi wambiri ndi mafuta opaka m'chipinda choyera.

 

Kusanthula kwa makompyuta

 

Gawo lina lomwe makampani opanga ma bearing apita patsogolo kwambiri ndi kugwiritsa ntchito pulogalamu yoyeserera ma bearing. Tsopano, magwiridwe antchito a ma bearing, moyo ndi kudalirika zitha kupitilira zomwe zidakwaniritsidwa zaka khumi zapitazo popanda kuchita mayeso okwera mtengo a labotale kapena mayeso akumunda. Kusanthula kwapamwamba komanso kophatikizana kwa ma rolling element bearing kungapereke chidziwitso chosayerekezeka pa magwiridwe antchito a ma bearing, kuthandizira kusankha bwino ma bearing ndikupewa kulephera kwa ma bearing msanga.

 

Njira zamakono zogwiritsira ntchito mphamvu ya kutopa zingathandize kuneneratu molondola za kupsinjika kwa zinthu ndi msewu wa raceway, kukhudzana ndi nthiti, kupsinjika kwa m'mphepete, ndi kudula kwa kukhudzana. Zimalolanso kupotoza kwathunthu kwa dongosolo, kusanthula katundu ndi kusanthula kusalingana kwa mabearing. Izi zipatsa mainjiniya chidziwitso chosintha kapangidwe ka bearing kuti agwirizane bwino ndi kupsinjika komwe kumachitika chifukwa cha kugwiritsa ntchito kwina.

 

Ubwino wina womveka bwino ndi wakuti mapulogalamu oyeserera amatha kuchepetsa nthawi ndi zinthu zomwe zimagwiritsidwa ntchito poyesa. Izi sizimangofulumizitsa njira yopangira komanso zimachepetsa ndalama zomwe zimagwiritsidwa ntchito poyesa.

 

N'zoonekeratu kuti chitukuko chatsopano cha sayansi ya zinthu pamodzi ndi zida zapamwamba zoyeserera ma bearing zidzapatsa mainjiniya chidziwitso chofunikira popanga ndikusankha ma bearing kuti agwire bwino ntchito komanso kulimba, monga gawo la chitsanzo chonse cha dongosolo. Kupitiliza kufufuza ndi chitukuko m'magawo awa kudzakhala kofunikira kwambiri pakuwonetsetsa kuti ma bearing akupitilizabe kupitirira malire m'zaka zikubwerazi.
