Gearbox bearing: anti-friction phetisong

Gearbox bearing (gearbox bear) - karolo ea lebokose la lisebelisoa tsa likoloi;ho roala ha moralo o mong kapa o mong, ho sebetsa joalo ka litšehetso tsa li-shafts le likere tsa gearbox.

Ho latela mofuta oa eona, palo ea likere, mokhoa oa ho fetisa torque lipakeng tsa likarolo le moralo, ho tloha ho 4 ho isa ho 12 kapa ho feta li-bearings tsa mefuta e fapaneng li ka sebelisoa ka lebokoseng la gear.Li-bearings li rarolla mathata a 'maloa:

● Ho etsa mesebetsi ea ts'ehetso bakeng sa li-shaft tsohle kapa feela (maemong a mangata - litšehetso tse peli bakeng sa li-shaft tsohle, ka har'a mabokose a mang merero e bonolo kapa e rarahaneng haholoanyane - tšehetso e le 'ngoe bakeng sa shaft ea ho kenya, litšehetso tse tharo bakeng sa shaft ea bobeli, joalo-joalo) ;
● Ho sebetsa e le setšehetso sa li-gear tse kentsoeng mokokotlong oa bobeli (ka har'a li-gearbox tse nang le li-gear tse kopantsoeng le li-gear tse pota-potileng mahala holim'a shaft ea bobeli);
● Ho fokotseha ha matla a khohlano ka har'a shaft le lisebelisoa tsa lisebelisoa (ho fokotseha ha tahlehelo ea torque phetisong, ho fokotsa mocheso oa likarolo tsa eona).

Tšebeliso ea li-bearings e tiisa ho kenngoa ka nepo ha likarolo tse tsamaeang tsa lebokose la li-gear le ho fokotsa haholo matla a khohlano a hlahang pakeng tsa likarolo tsena.Boemo le litšoaneleho tsa li-bearings li khetholla ts'ebetso ea lebokose la li-gear, bokhoni ba eona ba ho fetisa le ho fetola torque, 'me ka kakaretso ho netefatsa taolo ea koloi.Ka hona, li-bearings tse tsofetseng le tse nang le sekoli li tlameha ho nkeloa sebaka, 'me e le ho etsa khetho e nepahetseng ea likarolo tsena, hoa hlokahala ho utloisisa moralo oa tsona, mefuta le tšebeliso ea tsona.

Mefuta, moralo le litšobotsi tsa li-gearbox bearings

Ka likoloing, terekere le li-gearbox tse ling tsa lipalangoang, ho sebelisoa li-bearings tse tloaelehileng tsa mefuta e mengata e meholo:

● Mola o le mong oa libolo tsa ho kopana tsa radial le angular;
● Khokahano ea lithako tse peli tsa bolo;
● Lirolara tse nang le mola o le mong;
● Roller conical mola o le mong;
● Nalete ea rolara-mola o le mong le mola o habeli.

E 'ngoe le e' ngoe ea mefuta ea li-bearings e na le litšobotsi tsa eona le ho sebetsa ka har'a li-gearbox.

Libolo tsa radial tsa mola o le mong.Li-bearings tse tloaelehileng haholo tse ka sebelisoang e le litšehetso bakeng sa li-shafts tsohle tsa gearbox.Ka mokhoa o hlophisitsoeng, e na le mehele e 'meli, pakeng tsa eona ho na le mola oa libolo tsa tšepe ka har'a karohano.Ka linako tse ling libolo li koaheloa ka mehele ea tšepe kapa ea polasetiki ho thibela tahlehelo ea lubrication.Li-bearings tsa mofuta ona li sebetsa hantle ka ho fetisisa mabokoseng a likoloi le a lithuthuthu a batlang a laetsoe habobebe, empa ka linako tse ling a boetse a fumanoa litšeng tse ling tsa mabokose a thepa.

Mola o le mong oa libolo tse khokahanyo.Li-bearings tsena hangata li bona meroalo ea radial le axial, hangata e sebelisoa e le litšehetso tse ka morao tsa li-shafts tsa mantlha le tsa bobeli, tseo nakong ea ts'ebetso ea lebokose la li-gear li ka tsamaisoang ke meroalo e lebisitsoeng haufi le axis (ka lebaka la motsamao oa li-synchronizer le khatiso ea tsona. ka likeereng).Ka mokhoa o hlophisitsoeng, ho kopana ha li-angular ho tšoana le ho bea ha radial, empa mehele ea eona e na le litopo tse thibelang hore mohaho o se ke oa oa tlas'a meroalo ea axial.

Ho sututsa angular ka mela e 'meli.Li-bearings tsa mofuta ona li hanyetsana haholo le meroalo e phahameng, kahoo hangata li sebelisoa e le tšehetso e ka morao bakeng sa shaft e ka sehloohong le ka linako tse ling e bohareng.Ka moralo, li-bearings tse joalo li tšoana le li-bearings tsa mela e le 'ngoe, empa li sebelisa mehele e pharaletseng e nang le litopo tsa ka ntle bakeng sa libolo.

Roller ea mola o le mong oa radial.li-bearings tsena li ka sebetsa tlas'a meroalo e phahameng ho feta li-ball bearings, kahoo li sebelisoa e le litšehetso bakeng sa li-shafts tsohle ka lebokoseng la lisebelisoa tsa likoloi - literaka, literekere, lisebelisoa tse khethehileng, mechine ea temo, joalo-joalo. , empa li sebelisa lirolara e le lintho tse roala-hang - li-cylinders tse khutšoane, hammoho le lesaka, tse kentsoeng lipakeng tsa mehele e nang le bokaholimo bo sephara bo kahare.

Roller conical-mola o le mong le mela e habeli.Li-bearings tsa mofuta ona hangata li lemoha meroalo ea radial le axial, ha li ntse li hanyetsa meroalo e phahameng ho feta li-ball bear.Li-bearings tse joalo li sebelisoa hangata e le litšehetso tse ka morao le tse ka pele tsa li-shafts tsohle, li-bearings tse nang le mela e 'meli li sebelisoa ka morao ho li-shafts tsa mathomo le tsa bobeli.Moralo oa ho beha sena o sebelisa li-rollers tse tapered, tse kentsoeng lipakeng tsa mehele e 'meli e nang le bokaholimo ba ka hare ba beveled.

Nale ea rolara-mola o le mong le mola o habeli.Li-bearings tsa mofuta ona, ka lebaka la moralo oa tsona, li na le litekanyo tse nyenyane tse nang le khanyetso e phahameng ea meroalo ea mahlaseli - sena se finyelloa ka ho sebelisa li-roller tse nyenyane tse bophara (li-nale) e le 'mele oa ho potoloha,' me ka linako tse ling ho phaella ka ho lahla mehele le / kapa li-cages.Ka tloaelo, li-bearings tsa nale li sebelisoa e le litšehetso tsa lisebelisoa mokokotlong oa bobeli, joalo ka ts'ehetso ea shaft ea bobeli (ha monoana oa eona o le qetellong ea molamu oa ho kenya letsoho), hangata joalo ka litšehetso tsa countershaft.
