Papiso ea li-rolling bearings le plain bearings

Bakeng sa tshebediso yadibering, thepa ea likhohlano ea li-bearings tse ntseng li phahama li ka aroloa ka li-bearings le li-sliding bearings, re ka khetha mefuta e fapaneng ea ho jara ho latela litlhoko tse khethehileng tsa tšebeliso, li-bearings le li-sliding bearings li na le litšobotsi tse fapaneng tsa tšebeliso,

Likarolo tse ka sehloohong tsali-bearingske:

1. Ho fokotsa likhohlano tse nyane (ho amana le ho thella ho se nang metsi), ho qala ka mokhoa o bonolo;

2. E ka jara meroalo ea radial le axial ka nako e le 'ngoe, e nolofatsa sebopeho se tšehetsang;

3. Tlhaloso ea mahlaseli e nyenyane, 'me tumello e ka boela ea felisoa ka mokhoa oa ho jarisa pele, kahoo ho nepahala ha potoloho ho phahame;

4. Ho fapanyetsana hantle le tlhokomelo e bonolo.

 

Likarolo tse ka sehloohong tsalibering tse hlakilengke:

1. Mosebetsi o tsitsitseng mme ha o na lerata;

2. Ho nepahala ho potoloha ho phahameng;

3. Ho lahleheloa ke likhohlano tse nyane nakong ea lubrication ea mokelikeli;

4. Boholo ba radial bo bonyenyane;

5. Matla a ho jara a phahameng.

 

Melemo le mefokolo ea li-bearings ke life ha li bapisoa le li-bearings tse thotang? Tlhahlobo e tjena:

 

Ha ho bapisoa le li-bearings tse hlakileng, li-rolling bearings li na le melemo e latelang:

1. Coefficient ea likhohlano ea li-rolling bearings e nyane ho feta ea li-sliding bearings, 'me katleho ea phetisetso e phahame. Ka kakaretso, coefficient ea khohlano ea li-bearings tse thellang ke 0.08-0.12, athe coefficient ea khohlano ea li-rolling bearings ke 0.001-0.005 feela;

2. Li-rolling bearings li hlophisitsoe, li hlophisitsoe ka mokhoa o tloaelehileng le tse akaretsang, tse loketseng ho hlahisa le ho fana ka bongata, 'me li bonolo haholo ho li sebelisa le ho li boloka;

3. Li-rolling bearings li entsoe ka tšepe e nang le tšepe 'me li tlas'a phekolo ea mocheso, kahoo li-bearings ha li na thepa e phahameng ea mechine le bophelo bo bolelele ba tšebeletso, empa hape li ka boloka litšepe tse theko e boima tse se nang ferrous tse sebelisoang ha ho etsoa li-bearings tse thellang;

4. Tlhaloso ea ka hare ea ho roala e nyenyane haholo, 'me ho nepahala ha machining ea karolo e' ngoe le e 'ngoe ho phahame, kahoo ho nepahala ha ho matha ho phahame. Ka nako e ts'oanang, ho thatafala ha bethe ho ka eketsoa ka ho kenya pele. Sena se bohlokoa haholo bakeng sa mechini e nepahetseng;

5. Li-bearings tse ling li ka jara mojaro oa radial le axial load ka nako e le 'ngoe, kahoo sebopeho sa ho beleha se ka nolofalloa;

6. Ka lebaka la ts'ebetso e phahameng ea phetisetso le mocheso o tlase oa mocheso oa li-rolling bearings, tšebeliso ea oli e tlotsang e ka fokotsoa, ​​​​'me ho tlotsa le ho lokisa ho bonolo haholoanyane;

7. Li-rolling bearings li ka sebelisoa habonolo ho uranium ka tsela leha e le efe ea sebaka.

 

 

Leha ho le joalo, ntho e 'ngoe le e' ngoe e arotsoe ka likarolo tse peli, 'me li-rolling bearings li boetse li na le mefokolo e itseng, tse ka sehloohong ke tsena:

1. Boima ba ho roala li-bearings bo nyane haholo ho feta ba li-sliding bearings tsa molumo o tšoanang, ka hona, boholo ba radial ba li-rolling bearings bo boholo. Ka hona, ketsahalong ea ho jara mojaro o moholo le ketsahalo e hlokang boholo bo nyane ba radial le sebopeho se kopaneng (joalo ka enjene e tukang ka hare ho crankshaft bearing), li-sliding bearings li sebelisoa haholo;

2. Ho sisinyeha le lerata la li-rolling bearings li kholo, haholo-holo nakong ea morao-rao ea tšebeliso, ka hona, ha litlhoko tse nepahetseng li phahame haholo 'me ho thothomela ha ho lumelloe, ho thata ho ba le li-bearings tse nang le bokhoni,' me phello ea li-sliding bearings ke. ka kakaretso molemo;

3. Li-rolling bearings li ameha ka ho khetheha ho lihlopha tse tsoang linaheng tse ling tse kang li-chips tsa tšepe, 'me hang ha lintho tse tsoang linaheng tse ling li kena ka har'a li-bearings, li tla hlahisa ho sisinyeha ho hoholo ha nakoana le lerata, le tla baka tšenyo ea pele. Ho phaella moo, li-rolling bearings li boetse li ka hlaseloa ke tšenyo ea pele ka lebaka la ho kenngoa ha tšepe. Esita le haeba tšenyo ea pele e sa etsahale, ho na le moeli oa bophelo ba li-bearings. Ka bokhutšoanyane, li-bearings li na le bophelo bo khuts'oane ba ts'ebeletso ho feta li-bearings tse hlakileng.

 

Ha ho bapisoa le li-bearings le li-sliding bearings, e 'ngoe le e' ngoe e na le melemo le melemo ea eona, 'me e' ngoe le e 'ngoe e na le ketsahalo e itseng e sebetsang, ka hona, tse peli ha li khone ho nkela sebaka ka ho feletseng,' me e 'ngoe le e' ngoe e tsoela pele ka tsela e itseng ebe e atolosa tšimo ea eona. Leha ho le joalo, ka lebaka la melemo e hlahelletseng ea li-rolling bearings, ho na le tšekamelo ea hore batho ba liehang ho fihla ba atlehe. Hajoale, li-rolling bearings li se li fetohile mofuta o ka sehloohong oa ts'ehetso ea mochini, 'me li sebelisoa haholo le ho feta.
