Umuheto ni ubwoko bw'umuheto, bivuga ubwoko bw'umuheto ukoreshwa n'umuheto wa radiator ikonjeshwa n'umwuka.
Mu buhanga mu by'ubukanishi, hari ubwoko bwinshi bwa bearing, ariko hari ubwoko buke gusa bukoreshwa mu bikoresho bya radiator: ibyuma bikoresha sliding friction, umupira ukoresha friction rolling, n'uruvange rw'ubwoko bubiri bwa bearing. Mu myaka ya vuba aha, inganda zikomeye za radiator zashyizeho ikoranabuhanga rishya ku byuma bikoresha bearing, nka magnetic bearing, water wave bearing, magnetic core bearing, na hinge bearing. . Radiator zisanzwe zikonjeshwa n'umwuka zikoresha cyane cyane bearing zirimo amavuta na bearing ball.
Amavuta yo guteka akoresha amavuta ni amabati yo guteka akoresha uburyo bwo gukurura. Amavuta yo guteka akoreshwa nk'amavuta yo kwisiga n'uburyo bwo kugabanya imbaraga. Mu ikoreshwa rya mbere, urusaku rw'imikorere ruba ruto kandi ikiguzi cyo kuyakora nacyo kiri hasi. Ariko, ubwo bwoko bw'amabati burasharira cyane, kandi ubuzima bwabwo buri inyuma cyane y'amabati yo guteka. Byongeye kandi, niba ubwo bwoko bw'amabati bukoreshejwe igihe kirekire, bitewe n'impamvu y'amabati yo guteka (ntibishoboka gukoresha amavuta yo guteka ku bikoresho bya radiateri ya mudasobwa, muri rusange ni amavuta asanzwe yo guteka ku mpapuro), amavuta yo guteka azagenda ahindagurika buhoro buhoro, kandi ivumbi naryo rizinjira muri ayo mabati, bigatuma umufana agenda buhoro, urusaku rukiyongera n'ibindi bibazo. Mu bihe bikomeye, ubushyuhe buterwa no kwangirika kw'amabati butera guhindagurika gukomeye. Ibi nibigaragara, fungura amavuta yo guteka kugira ngo wongere lisansi, cyangwa ugomba kuyakuraho hanyuma ugure umufana mushya.
Umupira uhindura uburyo bwo gukururana kw'umupira, ugakoresha gukururana guhindagurika, bigabanya neza uburyo bwo gukururana hagati y'ubuso bw'umupira, bikanoza neza ubuzima bw'umupira ushyushye, bityo bikongera igihe cyo gukora cya radiator. Ingorane ni uko inzira irushaho kugorana, bigatuma ikiguzi cyiyongera kandi urusaku rw'akazi rukazamuka.
