Ni ubuhe bwoko butandukanye bw'udupira twa keramike?

 

Ibyuma bya keramikeharimo ibyuma bya zirconia ceramic bearings, ibyuma bya silicon nitride ceramic bearings, na silicon carbide ceramic bearings. Ibikoresho by'ingenzi bikoreshwa muri ibyo bikoresho ni zirconia (ZrO2), silicon nitride (Si3N4), na silicon carbide (SiC), bifite ubukana bwinshi, ubushobozi bwo kwangirika cyane, ubushobozi bwo guhangana n'ubushyuhe bwinshi, ubushobozi bwiza bwo gukora, no kwirinda oxidation.

 

By’umwihariko, imitako ya ceramic ishobora gushyirwa mu byiciro hakurikijwe ibikoresho ku buryo bukurikira:

 

Okiside ya ZirconiumIbyuma bya Ceramic: Impeta zo kuzenguruka n'ibintu bizunguruka bikozwe mu bikoresho bya zirconia (ZrO2) bya ceramic. Ubusanzwe ikiraro gikozwe muri polytetrafluoroethylene (PTFE), ariko ibikoresho byihariye nka nylon y'ikirahure ikoreshwa mu byuma bya plastike 66 (RPA66-25), plastike zidasanzwe za tekiniki (PEEK, PI), icyuma kitagira umugese (AISI SUS316), na brass (Cu) nabyo birashobora gukoreshwa.

 

Silikoni NitrideIbyuma bya Ceramic: Impeta zo guterura n'ibintu bizunguruka bikozwe muri silicon nitride (Si3N4). Ugereranyije na ZrO2 bearing, zifite umuvuduko mwinshi n'ubushobozi bwo gutwara kandi zishobora kwihanganira ubushyuhe bwinshi.

 

Ibyuma bya keramike bya karubide ya silikoni: Impeta zo guterura n'ibintu bizunguruka bikozwe muri karubide ya silikoni (SiC), bifite imiterere myiza nko gukomera cyane, kudashira, gukomera, no kudacika intege.

 

Byongeye kandi, ibyuma bya ceramic bishobora gushyirwa mu byiciro hakurikijwe imiterere ku buryo bukurikira:

 

Ibyuma bya keramike byose: Impeta n'ibintu bizingira byombi bikozwe mu bikoresho bya ceramic. Aka kazu gatanga amahitamo atandukanye, nka polytetrafluoroethylene (PTFE), nylon 66, polyetherimide (PEEK), polyimide (PI), icyuma kitagira umugese, cyangwa aluminiyumu yihariye yo mu kirere.

 

Ibyuma bya keramike bya Hybrid: Impeta zikozwe mu cyuma gifata cyangwa icyuma kitagira umugese, mu gihe ibintu bizingira ari imipira ya keramike. Zifite imiterere myiza nko kuba nkeya, gukomera cyane, kudashira, gukomera, no kudahuzagurika cyane, kandi igihe cyazo cyo gukora kiragabanuka cyane.

 

Ibyuma bya keramikebishobora gushyirwa mu byiciro hakurikijwe porogaramu ku buryo bukurikira:

 

Amapine yihuta cyane: Akoreshwa cyane cyane mu bikoresho byihuta cyane kandi bifite ubuhanga buhanitse. Afite ubushobozi buke bwo guhagarara mu gihe cy'ingufu, imbaraga nyinshi zo gukanda, uburemere bworoheje, kandi ashobora kwihanganira ubushyuhe bwinshi.

 

Ibyuma bipima ubushyuhe bwinshi: Bikoreshwa mu bikoresho bipima ubushyuhe bwinshi, bishobora kwihanganira ubushyuhe bugera kuri 1200°C, kandi bifite ubushobozi bwo kwisiga amavuta.

 

Ibyuma birwanya ingese: Bikoreshwa ahantu hakomeye hasaba kurwanya aside ikomeye, alkali, uruvange rw'ibinyabuzima, cyangwa amazi yo mu nyanja.

 

Ibyuma birwanya ingufu za rukuruzi: Bidakoresha ingufu za rukuruzi, bikoreshwa mu bikoresho bigabanya ingufu za rukuruzi, ibikoresho bitanga ingufu, nibindi, birinda neza ko ibice bigwa cyangwa bigacika.

 

Ibyuma bikingira amashanyarazi: Bifite ubushobozi bwo guhangana n'ibice byabyo, birinda ko ibice bihindagurika kandi bigacika, bikunze gukoreshwa mu bikoresho by'amashanyarazi.

 

Amasafuriya yo mu bwoko bwa Vacuum Bearings: Imiterere myiza yo kwisiga, ikoreshwa ahantu hashyushye cyane.
