Embonini yokukhiqiza, amathuluzi omshini ayimishini ebalulekile evumela ukukhiqizwa kwezingxenye nezingxenye ezinembile. Ingxenye ebalulekile yamathuluzi omshini yi-spindle, ethwala ithuluzi lokusika futhi ijikeleze ngesivinini esikhulu ukwenza imisebenzi yomshini. I-spindle kumele ifakwe kuma-bearings angasekela isisindo sayo futhi amelane namandla akhiqizwa ngesikhathi somshini.
Ngokwesiko, ama-ball bearings nama-roller bearings kube yizinhlobo zama-bearings ezisetshenziswa kakhulu kumathuluzi omshini. Kodwa-ke, njengoba isidingo sokunemba nokusebenza okuphezulu sikhula, kuye kwathuthukiswa izinhlobo ezintsha zama-bearings, njenge-gas bearings. Ama-gas bearings angama-non-contact bearings asebenzisa ifilimu encane yegesi, ngokuvamile umoya noma i-nitrogen, ukusekela isici esijikelezayo. Anikeza izinzuzo eziningana ngaphezu kwama-bearings endabuko, njengokungqubuzana okuphansi, ikhono eliphezulu lesivinini, kanye nokunciphisa okungcono.
Enye into esetshenziswe ngempumelelo njengento yokuthwala igesi kumathuluzi omshini yi-granite. Ama-granite gas bearings anezakhiwo eziningana ezihlukile ezenza kube ukukhetha okukhangayo kwezicelo zokusebenza okuphezulu. I-granite iyinto yemvelo eyakhiwe nge-magma epholile, futhi inesakhiwo esihle kakhulu nesilinganayo sokusanhlamvu. Lokhu kuyenza imelane kakhulu nokuguguleka nokuguquka, ngisho nangaphansi kwemithwalo esindayo kanye nesivinini esikhulu.
Ama-bearings egesi e-granite nawo anesilinganiso sokuqina okuphezulu kakhulu kwesisindo, okusho ukuthi angasekela isisindo esikhulu ngokuphambuka okuncane. Lokhu kubaluleke kakhulu kumathuluzi omshini, lapho i-spindle ingaba nesisindo esingamakhilogremu angamakhulu amaningana futhi kumele ifakwe ngokunemba okuphezulu. Ngaphezu kwalokho, i-granite ine-coefficient ephansi kakhulu yokwanda kokushisa, okusho ukuthi cishe ayinakuguquguquka ngenxa yezinguquko ekushiseni. Lokhu kubalulekile kumathuluzi omshini, lapho ukushintshashintsha kwezinga lokushisa kungabangela izinguquko ezinkulu ngobukhulu bezingxenye ezishiswayo.
Umthamo wokuthwala wezinsimbi zegesi zegranite uncike ezintweni eziningana, njengosayizi nesimo sezinsimbi, izimo zokusebenza (isivinini, izinga lokushisa, ingcindezi), kanye nezakhiwo zezinto zegranite. Ngokuvamile, izinsimbi zegesi zegranite zingasekela imithwalo esukela kumaNewton ambalwa kuya kuma-kilo-Newton amaningana, kuye ngobukhulu kanye nomklamo wezinsimbi. Zingasebenza futhi ngesivinini esifinyelela emashumini ezinkulungwane zokujikeleza ngomzuzu, okuphakeme kakhulu kunezinsimbi zebhola noma zeroller zendabuko.
Ekuphetheni, ama-granite gas bearings awubuchwepheshe obuthembisayo bokusetshenziswa ngesivinini esikhulu nangokunembile kumathuluzi omshini. Anikeza izinzuzo eziningana ngaphezu kwama-bearings endabuko, njengokungqubuzana okuphansi, ikhono eliphezulu lesivinini, kanye nokumanzisa okungcono. Umthamo wokuthwala wama-granite gas bearings uncike ezintweni eziningana, kodwa angasekela imithwalo ephezulu futhi asebenze ngesivinini esiphezulu. Ngocwaningo oluqhubekayo kanye nentuthuko, ama-granite gas bearings angaba yingxenye ejwayelekile kumathuluzi omshini wesikhathi esizayo.
