Ceramic yokhala ndi chilolezo chovomerezeka

 

Zojambula za Ceramic amapereka maubwino angapo pazitsulo zachitsulo zachikhalidwe, zomwe zimawapanga kukhala zosankha zodziwika bwino pamagwiritsidwe osiyanasiyana, makamaka omwe amafunikira magwiridwe antchito apamwamba.

 

Zojambula za Ceramiczimabwera mosiyanasiyana, nthawi zambiri zokhala ndi ceramic, ceramic ndi PEEK kapena PTFE makola, ndi ceramic wosakanizidwa. Zophatikiza za ceramic zimakhala ndi zida za ceramic ndi zitsulo zosapanga dzimbiri. Zida za Ceramic zomwe zimagwiritsidwa ntchito pafupipafupi ndi Zirconia (ZrO2) ndi Si3N4 (Silicon Nitride) kapena zimadziwika kuti ndi zitsulo zakuda za ceramic.

 

Muyezo wovomerezeka wa mayendedwe a ceramic ndi wofanana ndi wamba wamba, womwe umagawika kwambiri kukhala chilolezo cha radial ndi chilolezo cha axial. Chilolezo cha radial chimatanthawuza kuchuluka kwa kayendedwe ka mphete ina yokhudzana ndi mphete yokhazikika kuchokera kumalo ena oipitsitsa kupita kumalo ena ovuta kwambiri pamene palibe katundu; Axial clearance imatanthawuza kuchuluka kwa kusuntha kwa mphete ina kuchokera pa malo oipitsitsa kupita kumalo ena okhudzana ndi mphete yokhazikika kuchokera kumalo ena apamwamba kupita kwina pamene palibe katundu.

 

Chilolezo muyezo wa zojambula za ceramicndizofanana ndi zonyamula wamba, ndipo kusankha chilolezo makamaka kumaganizira zinthu zotsatirazi:

 

Chikoka choyenerera: kugwirizana pakati pa mphete yamkati yachitsulo ndi shaft, ndi kugwirizana pakati pa mphete yakunja ndi kuphulika kwa nyumba kudzakhudza kukula kwa chilolezo. Kusokonezeka kwapakati kumapangitsa kuti chilolezocho chichepe, pamene kusiyana kwapakati kumawonjezera chilolezo.

 

Zotsatira za kutentha: Kunyamula kumatulutsa kutentha panthawi yogwira ntchito, zomwe zimapangitsa kuti kutentha kwa mkati kukwere, zomwe zimapangitsa kuti shaft, nyumba ndi ziwalo zoberekera ziwonjezeke, zomwe zimakhudzanso kukula kwa chilolezo.

 

Zotsatira za katundu: Pamene katunduyo akulemedwa, amatulutsa kusintha kwa elasticity, komwe kumakhudza kukula kwa chilolezo.

 

Muyezo wapadera wovomerezeka ukhoza kutsimikiziridwa poyang'ana miyezo yoyenera ya dziko kapena chidziwitso chaukadaulo choperekedwa ndi wopanga. Mwachitsanzo, C0 imasonyeza chilolezo chovomerezeka, ndipo C2, C3, C4, C5, ndi zina zotero, imasonyeza kalasi yachilolezo yomwe ndi yaying'ono kapena yokulirapo kuposa chilolezo chovomerezeka.
