Mfundo zotsatirazi ziyenera kuganiziridwa posankha mapeto okhazikika a chithandizo cha galimoto (chomwe chimatchedwa kuti mapeto okhazikika): (1) zofunikira zowongolera molondola pazida zoyendetsedwa; (2) chikhalidwe cha katundu woyendetsedwa ndi galimoto; (3) kunyamula kapena kuphatikizika koyenera kuyenera kupirira mphamvu inayake ya axial. Kutengera zinthu zitatu zomwe tafotokozazi, mayendedwe a mpira wa groove nthawi zambiri amagwiritsidwa ntchito ngati chisankho choyamba pamagalimoto okhazikika ang'onoang'ono komanso ang'onoang'ono.ma motors apakati.
Ma bere a mpira wakuya ndi omwe amagwiritsidwa ntchito kwambiri. Pamene mayendedwe a mpira wakuya akagwiritsidwa ntchito, makina opangira ma motor ndi osavuta komanso osavuta kusamalira. Mipira yakuya ya groove imagwiritsidwa ntchito makamaka kunyamula katundu wa radial, koma pamene chiwongoladzanja cha ma radial chiwonjezeke, chimakhala ndi mawonekedwe a makwerero a mpira wa angular ndipo amatha kunyamula katundu wa radial ndi axial; liwiro likakhala lalitali ndipo mayendedwe a mpira wokhotakhota sali oyenera, atha kugwiritsidwanso ntchito kunyamula katundu wa axial. Poyerekeza ndi mitundu ina ya mayendedwe ndi miyeso yofanana ndi miyeso yofanana ndi mayendedwe a mpira wakuya, mtundu uwu wa kubereka uli ndi ubwino wa coefficient otsika ndi kuthamanga kwa malire, koma kuipa kwake ndikuti sikumakhudzidwa komanso sikuyenera kunyamula katundu wolemera.
Pambuyo poyika mpira wakuya wa groove pa shaft, mawonekedwe a radial a shaft kapena nyumba mbali zonse ziwiri akhoza kuchepetsedwa mkati mwa axial clearance range of the bear. Kumbali ya radial, chonyamulira ndi shaft zimatengera kusokoneza, ndipo chonyamula ndi kumapeto kwa chipinda chokhalamo kapena nyumba zimatengera kusokoneza pang'ono. Cholinga chachikulu chosankha kuyenerera uku ndikuwonetsetsa kuti chilolezo chogwira ntchito ndi zero kapena cholakwika pang'ono panthawi yagalimoto, kuti magwiridwe antchito amtunduwu azikhala bwino. Kumayambiriro kwa axial, kukwanira kwa axial kwa malo omwe ali ndi malo ndi magawo okhudzana nawo ayenera kutsimikiziridwa mophatikizana ndi momwe zimakhalira zoyandama. Mphete yamkati yamtundu wamtunduwu imachepetsedwa ndi gawo loyika malire (mapewa) pamtengowo ndi mphete yolumikizira, ndipo mphete yakunja yonyamula imayendetsedwa ndi kulekerera koyenera kwa kunyamula ndi chipinda chonyamula, kutalika kwa kuyimitsidwa kwa zotchingira zamkati ndi zakunja, komanso kutalika kwa chipinda chonyamula.
(1) Pamene mapeto oyandama amasankha chonyamula cholekanitsa ndi mphete zamkati ndi zakunja, mphete zakunja zazitsulo kumbali zonse ziwiri zimagwirizanitsidwa popanda chilolezo cha axial.
(2) Pamene mapeto oyandama amasankha kunyamula kosalekanitsidwa, kutalika kwina kwa axial chilolezo kumasiyidwa pakati pa mphete yakunja ya kunyamula ndi kuyimitsidwa kwa chivundikirocho, ndipo kugwirizana pakati pa mphete yakunja ndi chipinda chonyamula sikuyenera kukhala cholimba kwambiri.
(3) Pamene galimoto ilibe mapeto omveka bwino ndi mapeto oyandama, mayendedwe a mpira wakuya amagwiritsidwa ntchito pamapeto onse awiri, ndipo mgwirizano woyenerera ndi wakuti mphete yakunja ya chiberekero chochepa imatsekedwa ndi chivundikiro chamkati ndipo pali kusiyana pakati pa mphete yakunja ndi chivundikiro chakunja kumbali ya axial; kapena mphete yakunja ya zimbalangondo kumbali zonse ziwiri ikugwirizana popanda chilolezo cha axial pakati pa mphete yakunja ya kunyamula ndi chivundikiro, ndipo pali kusiyana pakati pa mphete yakunja ndi chivundikiro chamkati kumbali ya axial.
Maubale ofananira omwe ali pamwambawa onse ndi maubale omveka bwino omwe amawunikidwa mwaukadaulo. Kukonzekera kokwanira kwenikweni kuyenera kufanana ndi machitidwe ogwiritsira ntchito galimotoyo, kuphatikizapo magawo enieni monga chilolezo, kukana kutentha, kulondola, ndi zina zotero muzosankha zonyamula magalimoto, komanso mgwirizano wofananira wa radial pakati pa chotengera ndi chipinda chonyamula.
Tikumbukenso kuti kusanthula pamwamba yekhamopingasa anaikamo ma motors, pomwe pamakina oyikiratu, kusankha kwa ma bere ndi maubale ofananira kuyenera kukhala ndi zofunikira zenizeni.
