Kubereka kuli ndi gawo lofunikira komanso losasinthika pakupanga kwamakina, komwe kumaphatikizapo kusiyanasiyana kwakukulu, zitha kumveka kuti palibe chotengera, shaft ndi chitsulo chosavuta. Zotsatirazi ndizomwe zimayambira pa mfundo yogwira ntchito ya ma bearings. The anagubuduza kubala anayamba pamaziko a kubala, ntchito mfundo anagubuduza mikangano m'malo kutsetsereka mikangano, zambiri tichipeza mphete ziwiri, gulu la anagubuduza thupi ndi khola wapangidwa amphamvu chilengedwe chonse, standardization, mkulu digiri ya serialization makina maziko. Chifukwa cha mitundu yosiyanasiyana yogwirira ntchito yamakina osiyanasiyana, zofunikira zosiyanasiyana zimayikidwa patsogolo pakugudubuza mayendedwe potengera kuchuluka kwa katundu, kapangidwe kake ndi magwiridwe antchito. Kuti izi zitheke, ma bere ogudubuza amafunikira mitundu yosiyanasiyana. Komabe, mawonekedwe ofunikira kwambiri amapangidwa ndi mphete yamkati, mphete yakunja, thupi lopindika ndi khola - zomwe nthawi zambiri zimatchedwa zidutswa zinayi zazikuluzikulu.
Kutengera chitsanzo
Kwa mayendedwe osindikizidwa, kuphatikiza mafuta ndi mphete yosindikizira (kapena chivundikiro cha fumbi) - chomwe chimadziwikanso kuti zidutswa zisanu ndi chimodzi. Mitundu yosiyanasiyana yonyamula imatchulidwa molingana ndi dzina la thupi logudubuza. Maudindo a zigawo zosiyanasiyana mu mayendedwe ndi: kwa mayendedwe apakati, mphete yamkati nthawi zambiri imafanana kwambiri ndi shaft, ndipo imagwira ntchito ndi shaft, ndipo mphete yakunja nthawi zambiri imakhala yosinthika ndi mpando wonyamula kapena dzenje lamakina, kusewera gawo lothandizira. . Komabe, nthawi zina, palinso mphete yakunja ikuthamanga, mphete yamkati yokhazikika yothandizira kapena mphete yamkati, mphete yakunja ikugwira ntchito nthawi yomweyo.
Pa ma thrust bearings, mphete yonyamulira imagwirizana kwambiri ndi shaft ndipo imasuntha pamodzi, ndi mpando wonyamula kapena bowo lachipolopolo lokhala ndi machesi ndikuthandizira mphete yonyamula. The anagubuduza thupi (mpira zitsulo, wodzigudubuza kapena singano) mu kubereka kawirikawiri mothandizidwa ndi khola wogawana anakonza pakati pa mphete ziwiri kwa anagubuduza kayendedwe, mawonekedwe ake, kukula ndi chiwerengero mwachindunji zimakhudza kubala katundu mphamvu ndi ntchito. Khola silingathe kulekanitsa thupi lozungulira, komanso kuwongolera kuzungulira kwa thupi lozungulira ndikuwongolera magwiridwe antchito amafuta.
Pali mitundu yambiri ya ma bearings ndipo ntchito zawo siziri zofanana, koma mfundo yogwira ntchito ya ma bearings imafotokozedwa pamwambapa.
