Gearbox yonyamula: anti-friction pakufalitsa

Gearbox yonyamula (gearbox) - gawo la gearbox ya zida zamagalimoto;kugubuduza kwa mapangidwe amodzi kapena imzake, kumachita ngati zothandizira ma shafts ndi magiya a gearbox.

Kutengera mtundu wake, kuchuluka kwa magiya, njira yotumizira makokedwe pakati pa zinthu ndi kapangidwe kake, kuchokera ku 4 mpaka 12 kapena kupitilira apo amitundu yosiyanasiyana angagwiritsidwe ntchito mu bokosi la gear.Bearings amathetsa mavuto ambiri:

● Kuchita ntchito za chithandizo cha ma shaft onse kapena okha (nthawi zambiri - zothandizira ziwiri za shaft zonse, m'mabokosi ena njira zosavuta kapena zovuta kwambiri - zothandizira imodzi ya shaft yolowera, zothandizira zitatu za shaft yachiwiri, ndi zina zotero) ;
● Kuchita ngati chithandizo cha magiya oyikidwa pa shaft yachiwiri (mu ma gearbox omwe ali ndi zida zogwirizanitsa ndi zida zozungulira zaulere pa shaft yachiwiri);
● Kuchepetsa mphamvu zotsutsana mu shaft ndi zida zothandizira (kuchepetsa kutayika kwa torque potumiza, kuchepetsa kutentha kwa mbali zake).

Kugwiritsiridwa ntchito kwa ma bearings kumatsimikizira kuyika kolondola kwa zigawo zosuntha za gearbox ndikuchepetsa kwambiri mikangano yomwe imabwera pakati pazigawozi.Mkhalidwe ndi mawonekedwe a ma bearings amatsimikizira magwiridwe antchito a gearbox, kuthekera kwake kufalitsa ndikusintha torque, ndikuwonetsetsa kuwongolera kwagalimoto.Choncho, mayendedwe ovala ndi opanda pake ayenera kusinthidwa, ndipo kuti apange chisankho choyenera cha zigawozi, m'pofunika kumvetsetsa mapangidwe awo, mitundu ndi kugwiritsidwa ntchito.

Mitundu, mapangidwe ndi mawonekedwe a ma gearbox

M'magalimoto, thirakitala ndi ma gearbox ena oyendera, mayendedwe oyenda amitundu ingapo amagwiritsidwa ntchito:

● Mipira yolumikizana ya mzere umodzi ndi yolumikizana;
● Mpira wokhala ndi mizere iwiri yolumikizana;
● Zodzigudubuza za mzere umodzi;
● Roller conical mzere umodzi;
● singano yodzigudubuza ya mzere umodzi ndi mizere iwiri.

Uliwonse wa mitundu ya mayendedwe uli ndi mawonekedwe ake komanso magwiridwe antchito mu ma gearbox.

Mipira yozungulira mzere umodzi.Ma bearings odziwika kwambiri omwe angagwiritsidwe ntchito ngati othandizira pazitsulo zonse za gearbox.Mwadongosolo, imakhala ndi mphete ziwiri, pakati pawo pali mzere wa mipira yachitsulo mu olekanitsa.Nthawi zina mipira imakutidwa ndi zitsulo kapena mphete zapulasitiki kuti zisawonongeke.Zonyamula zamtunduwu zimagwira ntchito bwino pamabokosi odzaza pang'ono agalimoto ndi njinga zamoto, koma nthawi zina zimapezekanso pamabokosi onyamula katundu.

Mipira yolumikizana ndi mzere umodzi.Ma bere awa nthawi zambiri amawona ma radial ndi axial katundu, amagwiritsidwa ntchito nthawi zambiri ngati zothandizira kumbuyo kwa ma shafts a pulayimale ndi achiwiri, omwe pakugwira ntchito kwa bokosi la giya amatha kunyamula katundu wotsogozedwa ndi axis (chifukwa chakuyenda kwa ma synchronizer ndi kutsindika kwawo. mu magiya).Mwachidziwitso, cholumikizira cha angular chimakhala chofanana ndi chotengera cha radial, koma mphete zake zimakhala ndi maimidwe omwe amalepheretsa kapangidwe kake kugwa pansi pa katundu wa axial.

Mpira wa mizere iwiri yokhotakhota.Zimbalangondo zamtunduwu zimagonjetsedwa kwambiri ndi katundu wambiri, choncho nthawi zambiri zimagwiritsidwa ntchito ngati chithandizo chakumbuyo kwa shaft yoyamba komanso nthawi zina yapakati.Mwa kapangidwe kake, zotengera zotere ndizofanana ndi mizere ya mzere umodzi, koma zimagwiritsa ntchito mphete zazikulu zokhala ndi kuyimitsa kunja kwa mipira.

Wodzigudubuza mzere umodzi wozungulira.mayendedwe awa akhoza kugwira ntchito pansi pa katundu wapamwamba kuposa mayendedwe a mpira, choncho amagwiritsidwa ntchito ngati zothandizira zitsulo zonse mu gearbox ya zida zamagalimoto - magalimoto, mathirakitala, zipangizo zapadera, makina a ulimi, etc. , koma amagwiritsa ntchito zodzigudubuza monga zinthu zogudubuza - masilinda afupiafupi, pamodzi ndi khola, omangidwa pakati pa mphete zokhala ndi malo amkati athyathyathya.

Roller conical mzere umodzi ndi mizere iwiri.Ma bearings amtunduwu nthawi zambiri amawona zonyamula ma radial ndi axial, pomwe amalimbana ndi katundu wambiri kuposa mayendedwe a mpira.Miyendo yotereyi imagwiritsidwa ntchito nthawi zambiri ngati zothandizira kumbuyo ndi kutsogolo kwazitsulo zonse, zitsulo zokhala ndi mizere iwiri zimagwiritsidwa ntchito kumbuyo kwazitsulo zoyambirira ndi zachiwiri.Mapangidwe a chimbalangondochi amagwiritsa ntchito zodzigudubuza za tapered, zomwe zimayikidwa pakati pa mphete ziwiri zokhala ndi zopindika zamkati.

Roller singano mzere umodzi ndi mizere iwiri.Zimbalangondo zamtunduwu, chifukwa cha kapangidwe kake, zimakhala ndi miyeso yaying'ono yolimbana ndi ma radial - izi zimatheka pogwiritsa ntchito ma roller ang'onoang'ono (singano) ngati matupi ozungulira, ndipo nthawi zina kuwonjezera pakusiya mphete ndi / kapena makola.Nthawi zambiri, zonyamula singano zimagwiritsidwa ntchito ngati zida zothandizira pa shaft yachiwiri, ngati chothandizira chachiwiri cha shaft (pamene chala chake chili kumapeto kwa shaft yolowera), nthawi zambiri ngati kuthandizira kwa shaft.
