Li-turntable bearings

Sebaka sa ho sebetsa sa rotary se sebelisoang hangata ho lisebelisoa tsa mochini oa CNC se kenyelletsa indexing workbench le CNC rotary workbench.

Tafole ea rotary ea CNC e ka sebelisoa ho fihlela motsamao oa phepelo ea selikalikoe. Ntle le ho hlokomela motsamao oa phepelo ea selikalikoe, tafole ea rotary ea CNC (e bitsoang turntable CNC) le eona e ka phethela motsamao oa indexing.

Tafole ea rotary e sebelisoa haholo mecheng e fapaneng ea ho sila ea CNC, mechini e tenang, li-lathe tse fapaneng tse otlolohileng, ho sila le lisebelisoa tse ling tsa mochini. Ntle le tlhokahalo ea hore tafole ea rotary e ka jara boima ba mosebetsi oa matsoho hantle, ho boetse hoa hlokahala ho netefatsa ho nepahala ha eona ho potoloha tlas'a mojaro.

The turntable bearing, e le karolo ea mantlha ea turntable, ha e hloke feela ho ba le matla a mangata a boima, empa hape e na le ho nepahala ho phahameng ho potoloha, bokhoni bo phahameng ba ho thibela ho phethola, le bokhoni bo phahameng ba lebelo nakong ea ts'ebetso ea turntable.

Ka moralo oalitafole tsa rotary, mefuta e sebelisoang haholo ea li-bearings e arotsoe ka mefuta e latelang:

Li-ball bearings:cylindrical rolara libere

Li-bearings tsa thrust ball li ka mamella matla a itseng a axial, kahoo ho beleha ho sebelisoa haholo-holo ho jara boima ba workpiece;Li-cylindrical rolara dibering, ka lehlakoreng le leng, li sebelisoa haholo-holo bakeng sa boemo ba mahlaseli le ho mamella matla a mahlaseli a ka ntle (joaloka matla a ho khaola, matla a ho sila, joalo-joalo). Mofuta ona oa moralo o sebelisoa haholo ebile o batla o le theko e tlase. Hobane bolo ea "thrust" ke "point-contact bear", matla a eona a axial a fokotsehile, 'me e sebelisoa haholo litafoleng tsa rotary tsa lisebelisoa tse nyane kapa tse mahareng. Ho feta moo, lubrication ea thrustballs le eona e thata le ho feta.

Lithako tsa Hydrostatic:Precision cylindrical rolara libere

Hydrostatic bearing ke mofuta oa ho thella o itšetlehileng ka phepelo ea kantle ea oli ea khatello mme e theha filimi ea oli e jereng moroalo oa hydrostatic ho fihlela ho tlotsa metsi. The hydrostatic bearing e lula e sebetsa tlas'a lubrication ea metsi ho tloha qalong ho ea ho emisa, kahoo ha ho na ho apara, bophelo bo bolelele ba tšebeletso le matla a tlaase a qalang; Ntle le moo, mofuta ona oa ho jara o boetse o na le melemo ea ho nepahala ha potoloho e phahameng, ho tiea ha filimi e kholo ea oli, 'me ho ka hatella ho sisinyeha ha filimi ea oli. Li-bearings tse nepahetseng tsa li-cylindrical roller li na le matla a matle a radial, 'me ka lebaka la tšebeliso ea li-bearings tse nepahetseng, ho nepahala ho potoloha ha tafole ea rotary le hona ho ka tiisoa hantle. Litafole tsa rotary tse sebelisang moqapi ona li ka mamella matla a axial a phahameng haholo, a mang a boima ba lithane tse fetang 200 'me a na le bophara ba ho fetoha ho feta 10 metres. Leha ho le joalo, mofuta ona oa moralo o boetse o na le mefokolo e itseng, hobane sehlahisoa sa hydrostatic se tlameha ho ba le sistimi e khethehileng ea phepelo ea oli ho fana ka oli ea khatello, tlhokomelo e rarahane le ho feta, 'me litšenyehelo li batla li phahame.

Lirolara tse tšetseng

Tšebeliso ea li-roller bearings holim'a li-turntables le eona e batla e tloaelehile. Li-roller bearings tse tšekaletseng li khetholloa ke litsela tse peli tsa lebelo ho bering, mela e 'meli ea li-roller tse hlophisitsoeng. Ha ho bapisoa le metsoako ea li-radial centering bearing ea setso,dibering rolara tse tsheletsengli kopane, li kopane 'me li nolofatsa moralo oa tafole, kahoo li fokotsa litšenyehelo tsa turntable.

Ho phaella moo, ka lebaka la ho jara pele ho optimized, li-bearings li na le tekanyo e phahameng ea ho satalla, e leng se tiisang ho tiea le ho nepahala ha turntable. Ka lebaka la moralo oa mela e 'meli ea li-roller tse tšetsoeng, nako e atlehang ea ho beleha e ka eketseha haholo, e le hore li-bearings tsena li be le khanyetso e phahameng ea nako ea ho phethola. Ho na le mefuta e 'meli ea li-roller bearings tse peli: ea pele ke cylindrical crossed roller bearings,' me ea bobeli ke li-bearings tse pota-potiloeng. Ka kakaretso, libering rolara cylindrical tšela ba theko e tlase ho feta tapered crossed rolara dibering le a loketse bakeng sa dikopo turntable ka lebelo batlang le tlaase; Thepa ea rolara e tšekaletseng e nka moralo o hloekileng oa roller e tapered, kahoo mofuta ona oa ho beha o na le:

• Ho nepahala ho phahameng ho matha

• Bokhoni ba lebelo le phahameng

• Ho fokotsa bolelele ba shaft le litšenyehelo tsa machining, phapang e fokolang ea geometry ka lebaka la ho atolosoa ha mocheso

• Sekhahla sa nylon, nako e tlaase ea inertia, torque e tlaase e qalang, ho bonolo ho laola indexing ea angular

• Optimized preload, ho satalla ho phahameng le ho phalla ho tlase

• Ho kopana le linear, ho satalla ho phahameng, ho nepahala ho phahameng ho tataisang opereishene ea rolara

• tšepe ea carburized e fana ka ts'ebetso e babatsehang ea ho hanyetsa le ho hanyetsa ho apara holimo

• E bonolo empa e tlotse hantle

Ha o kenya li-bearings, moreki o hloka feela ho kenya li-bearings tse tšetsoeng ho ea ho boleng bo khothalelitsoeng, ho fapana le ho ba le ts'ebetso e rarahaneng ea ho hlophisoa joalo ka li-hydrostatic bearings. Li-roller bearings li bonolo ho kenya le ho le bonolo ho fetola foromo ea pele ea ho kenya kapa mokhoa oa tlhokomelo. Li-roller bearings li loketse mefuta eohle ea mechini e tenang e otlolohileng kapa e otlolohileng, hammoho le lits'ebetso tse joalo ka liloala tse otlolohileng, mochini o thibang o otlolohileng le metjhini e meholo ea ho sila.

Joalo ka karolo ea mantlha ea "spindle le turntable" ea sesebelisoa sa mochini, ho beleha ho bapala karolo ea bohlokoa ts'ebetsong ea ts'ebetso ea mochini. E le hore re khone ho khetha boholo bo nepahetseng le mofuta oa ho beleha, re lokela ho nahana ka maemo a fapaneng a ts'ebetso, joalo ka lebelo la ho matha, lubrication, mofuta o ntseng o phahama, ho satalla ha spindle, ho nepahala le litlhoko tse ling. Mabapi le ho jara ka boeona, ke feela ka ho utloisisa ka botlalo likarolo tsa eona tsa moralo le melemo le melemo e hlahisoang ke hore re ka hlahisa ts'ebetso e ntle ka ho fetisisa ea ho beha.
