I-Planetary Roller Screw(uhlobo olujwayelekile) iwumshini wokudlulisa ohlanganisa ukunyakaza kwe-helical kanye nokunyakaza kweplanethi ukuguqula ukunyakaza kwesikulufu sibe yi-screwukunyakaza komugqakwemantongomane. I-Planetary Roller Screws inezici zomthamo oqinile wokuthwala umthwalo, ukuqina okuphezulu, ukunemba okuphezulu, ukumelana nokugqokwa, ukumelana nokushaqeka nempilo ende, njll., ezisetshenziswa kakhulu ezimbonini nezokuvikela nezempi:
Ukwakhiwa:Izikulufu ze-roller zeplanethi zakhiwe ikakhulukaziizikulufu, ama-roller, amantongomane, iringi yangaphakathi yegiya, ikheji nendandatho enwebekayo yokugcina;
Imodi yokunyakaza:izikulufu ze-roller zeplanethi emsebenzini, isikulufu sivame ukusetshenziswa njengokufakwa kwamandla, kuphela eduze kwe-eksisi yaso yokujikeleza; i-nut ivame ukuxhunyaniswa nomthwalo, kuphela eduze kwe-axis yayo yokunyakaza; i-roller enatini kanye nokunyakaza kweplanethi phakathi kwesikulufu kanye nokugudluzwa kwe-axial kwentongomane okuhlobene ne-zero, kanye nenati kanye nokunyakaza ku-axial direction.
Nge-screw roller yeplanethi ezimbonini ezihlukahlukene ziqhubeka nokujula, izimo zokusetshenziswa kwayo nazo ziza kakhulu, ukuze zivumelane nezimo ezihlukahlukene zohlelo lokusebenza kanye nezimo zokufaka, isakhiwo sefomu sibuye sithuthuke njalo. Izikulufu ezijwayelekile, ezijikelezayo, ezibuyela emuva, ezihlukile nezinye zeplanethi zisetshenziswa kabanzi:
(1) Uhlobo olujwayelekile: Ngokuvamile, isikulufu siyilungu elisebenzayo futhi inathi liyilungu eliphumayo. Ingakwazi ukufeza ukushaywa okukhulu, okufanelekile ezindaweni ezinokhahlo, umthwalo omkhulu, isivinini esikhulu nezinye izikhathi, ikakhulukazi ezisetshenziselwa amathuluzi omshini wokunemba, amarobhothi, imishini yezempi kanye nezinye izinkambu, okwamanje uhlobo olusetshenziswa kakhulu;
(2) Uhlobo oluhlanekezelwe: isimo salo sesakhiwo sifana nohlobo olujwayelekile, umehluko ukuthi ayinayo indandatho yegiya yangaphakathi, amazinyo aqondile emikhawulweni yomibili ye-screw mesh namagiya kuzo zombili iziphetho zerola, futhi inati njengengxenye esebenzayo, ubude bayo bukhulu kakhulu kunohlobo olujwayelekile. Ngokuvamile, i-nut of theisikulufu se-rola yeplanethi ehlanekezelweyilungu elisebenzayo, isikulufu siyilungu eliphumayo, futhi akukho ukususwa kwe-axial okuhlobene phakathi kwerola nesikulufu, esisetshenziselwa kakhulu imithwalo emincane nephakathi nendawo, imivimbo emincane kanye nezimo zohlelo lokusebenza ezinesivinini esikhulu, kanye nenani elikhulu kunawo wonke. inzuzo ukuthi i-nati yayo ingasetshenziswa njenge-motor rotor ukufeza umklamo odidiyelwe we-motor kanye nesikulufu ukuze kwakhiwe i-compact one-piece electro-mechanical actuator;
(3) Uhlobo olujikelezayo kabusha: Uma kuqhathaniswa nohlobo olujwayelekile, ikhipha iringi yegiya yangaphakathi bese yengeza isakhiwo se-cam, umsebenzi wayo ofana nowokubuyisela isikulufu sebhola, ukuze wenze irola libuyele endaweni yokuqala ngemva kokuzungezisa. kumantongomane isonto elilodwa. Izici zesakhiwo se-isikulufa se-roller yeplanethiukwandisa inani lezintambo ezihilelekile ekuhlanganyeleni, ngakho-ke inokuqina okuphezulu nomthamo omkhulu womthwalo, futhi isetshenziswa kakhulu ezinhlelweni ezidinga ukuqina okuphezulu, umthamo omkhulu womthwalo, kanye nokunemba okuphezulu, okufana nemishini yezokwelapha, amathuluzi okusebenza ngokunemba, neminye imikhakha. . Okubi ukuthi isakhiwo sayo sendandatho ye-cam sizokhiqiza umthelela wokudlidliza, kunenkinga yomsindo;
(4) Uhlobo oluhlukile: Uma kuqhathaniswa nohlobo olujwayelekile, iringi yegiya yangaphakathi iyasuswa futhi ayikho ingxenye yegiya kurola. Izici zesakhiwo sesikulufu esihlukile se-planeetary roller zenza kube nokwenzeka ukuthola umthofu omncane, ofanele izinhlelo zokusebenza ezinezilinganiso ezinkulu zokudlulisela kanye nomthamo ophezulu wokuthwala umthwalo. Kodwa-ke, phakathi nokunyakaza kwayo, izintambo zizokhiqiza into e-sliding, ejwayele ukugqoka ngaphansi kwemithwalo esindayo, okuholela ekulahlekelweni kokunemba, ukunciphisa ukwethembeka nezinye izinkinga.
Isikulufu serola esihlanekezelwe ku-actuator yomugqa
Ukungena kwesikulufu seplanethi yeplanethi kulindeleke ukuthi kukhuphuke, kuthathelwe indawo ingxenye yenkundla yezikulufu zebhola kanye nokudluliswa kwe-hydraulic:
(1) Uma kuqhathaniswa nokudluliswa kwezikulufu zebhola, izikulufu ze-roller zeplanethi zinokuthwala okunamandla, zingasetshenziswa ezimweni eziyinkimbinkimbi nezinzima zokusebenza, impilo ende kanye nezinye izinzuzo, kulindeleke ukuthi zisetshenziswe emkhakheni wamathuluzi omshini, ugesi wamarobhothi. amasilinda nezinye izimo;
(2) Ngokusekelwe esakhiweni sokudlulisa ukunemba kwesikulufa seplanethi yerola, ukuze kunqotshwe ukuguquguquka kwemvelo kwe-hydraulic okujwayelekile kwemvelo, ukwethembeka okuphansi, ukusetshenziswa kokunakekelwa okungeyikho kanye nokunye ukushiyeka, kulindeleke ukuthi kuthathelwe indawo ingxenye yomshini wokudluliswa kwe-hydraulic yesehlakalo.
