Li-actuator tsa electromechanical li tla ka mefuta e mengata, 'me mekhoa e tloaelehileng ea ho khanna kelikurufu tse etellang pele, li-ball screws, le li-roller screws. Ha moqapi kapa mosebelisi a batla ho tloha ho hydraulics kapa pneumatics ho ea ho electromechanical motion, li-roller screw actuators hangata ke khetho e ntle ka ho fetisisa. Li fana ka litšobotsi tse tšoanang tsa ts'ebetso ho li-hydraulics (matla a phahameng) le pneumatics (lebelo le phahameng), tsamaisong e fokolang haholo.
A roller screwe nkela sebaka sa libolo tse recirculating ka lirolara tse khoele. Lirolara li hlophisitsoe ka tlhophiso ea lipolanete 'me bobeli ba bona ba bilika ka lilepe tsa bona le ho potoloha linate. le nate.
The roller screw ke mofuta oa screw drive e nkelang libolo tse recirculating ka lirolara tse khoele. Lipheletsong tsa lirolara li na le meno a ho kopanya ka mehele e kentsoeng pheletsong e 'ngoe le e 'ngoe ea linate. Lirolara ka bobeli li bilika lilepe tsa tsona 'me li potoloha linate, ka tlhophiso ea polanete. (Ke ka lebaka leo li-screws tsa roller li boetseng li bitsoang "planetary roller screws".
Geometry ea screw roller e fana ka lintlha tse ngata tsa ho ikopanya ho feta kamoo ho ka khonehang ka abolo screw. Sena se bolela hore li-roller screws hangata li na le matla a holimo a matla le ho tiea ho feta li-screws tsa bolo tse boholo bo lekanang. 'Me likhoele tse ntle (pitch) li fana ka monyetla o phahameng oa mochine, ho bolelang hore torque e fokolang ea ho kenya e ea hlokahala bakeng sa mojaro o fanoeng.
Monyetla oa bohlokoa oa moralo oa li-screws (ka tlase) holim'a li-screws tsa bolo (holimo) ke bokhoni ba ho ba le lintlha tse ngata tsa ho ikopanya sebakeng se le seng.
Kaha lirolara tsa tsona tse jarang moroalo ha li hokahane, li-roller screws ka tloaelo li ka tsamaea ka lebelo le holimo ho feta li-ball screws, tse tlamehang ho sebetsana le matla le mocheso o hlahisoang ke libolo tse thulang tse ling le ka likatiba tsa ho qetela tsa ho potoloha.
Li-screws tse kentsoeng ka rolara
Moralo o sothehileng o sebetsa ka mokhoa o ts'oanang le sekoti se tloaelehileng sa roller, empa nate ha e le hantle e fetoleloa ka hare-ntle. Kahoo, lentsoe "inverted roller screw." Sena se bolela hore li-roller li pota-potile sekoti (ho e-na le linate), 'me screw e kenngoa feela sebakeng seo li-roller li potolohang ho sona. Ka hona, nate e fetoha mokhoa o khethollang bolelele, ka hona, hangata e telele ho feta nate e holim'a sekoti se tloaelehileng sa roller. Ekaba screw kapa nate e ka sebelisoa bakeng sa molamu oa ho sutumetsa, empa lisebelisoa tse ngata tsa actuator li sebelisa screw molemong ona.
Ho hlahisa sekoti se sothehileng ho hlahisa phephetso ea ho theha likhoele tse nepahetseng tsa ka hare bakeng sa linate ka bolelele bo batlang bo lelelele, ho bolelang hore ho sebelisoa mekhoa ea machining. Sephetho ke hore likhoele li bonolo, ka hona, litekanyetso tsa mojaro oa li-screws tse khelohileng li tlase ho feta tsa li-screws tse tloaelehileng. Empa li-screws tse khelohileng li na le molemo oa ho ba compact haholoanyane.
