Planetary Roller Screw(tus qauv hom) yog ib qho kev sib kis mechanism uas sib txuas lus helical thiab planetary motion los hloov cov lus tsa suab ntawm cov ntsia hlau rau hauvlinear zogntawm txiv ntoo.Planetary Cov Menyuam Screws muaj cov yam ntxwv ntawm cov khoom muaj peev xwm nqa tau, siab rigidity, siab precision, hnav tsis kam, poob siab tsis kam thiab lub neej ntev, thiab lwm yam, uas tau siv dav hauv kev lag luam thiab kev tiv thaiv thiab kev ua tub rog:
Kev sib xyaw:planetary roller screws feem ntau yog tsim los ntawmntsia hlau, rollers, ceev, internal iav nplhaib, tawb thiab elastic retaining nplhaib;
Mod zog:planetary roller screws hauv kev ua haujlwm, cov ntsia hlau feem ntau yog siv los ua lub zog nkag, tsuas yog nyob ib ncig ntawm nws tus kheej axis ntawm kev sib hloov;txiv ntseej yog feem ntau txuas nrog lub load, tsuas yog raws nws tus kheej axis ntawm txav;cov menyuam hauv cov txiv ntoo thiab lub ntiaj teb txav ntawm cov ntsia hlau thiab cov axial txav ntawm cov txiv ntoo txheeb ze rau xoom, thiab cov txiv ntoo ua ke nrog kev txav mus rau hauv axial kev taw qhia.
Nrog lub ntiaj teb cov menyuam ntsia hlau nyob rau hauv ntau yam kev lag luam txuas ntxiv mus tob, nws daim ntawv thov scenarios kuj tuaj ntau thiab ntau dua, txhawm rau hloov mus rau qhov sib txawv ntawm daim ntawv thov ib puag ncig thiab kev teeb tsa, cov qauv ntawm daim ntawv kuj tseem nyob hauv kev txhim kho tas li.Standard, cyclic, thim rov qab, sib txawv thiab lwm yam planetary roller screws yog siv ntau dua:
(1) Hom qauv: Feem ntau, cov ntsia hlau yog cov tswv cuab nquag thiab cov txiv ntoo yog cov tswv cuab tso tawm.Nws tuaj yeem ua tiav cov hlab ntsha loj, haum rau qhov hnyav ib puag ncig, kev thauj khoom siab, kev kub ceev thiab lwm lub sijhawm, feem ntau yog siv hauv cov cuab yeej siv tshuab precision, neeg hlau, cov cuab yeej siv tub rog thiab lwm yam, tam sim no yog hom siv dav tshaj plaws;
(2) Inverted hom: nws cov qauv qauv zoo ib yam li hom qauv, qhov txawv yog tias nws tsis muaj lub nplhaib sab hauv, cov hniav ncaj ntawm ob qho kawg ntawm cov ntsia hlau mesh nrog lub zog ntawm ob qho kawg ntawm cov menyuam, thiab cov txiv ntoo raws li qhov nquag nquag, qhov ntev ntawm qhov loj dua li ntawm hom qauv.Feem ntau hais lus, lub txiv ntoo ntawm lubinverted planetary menyuam ntsia hlauyog cov tswvcuab nquag, cov ntsia hlau yog cov tswvcuab tso tawm, thiab tsis muaj qhov sib txawv axial hloov chaw ntawm cov menyuam thiab cov ntsia hlau, uas yog tsuas yog siv rau cov khoom me me thiab nruab nrab, me me strokes thiab high-speed daim ntawv thov scenarios, thiab nws qhov loj tshaj. qhov zoo dua yog tias nws cov txiv ntseej tuaj yeem siv los ua lub cev muaj zog rotor kom ua tiav kev sib xyaw tsim ntawm lub cev muaj zog thiab cov ntsia hlau los ua ib qho kev cog lus ib-thooj electro-mechanical actuator;
(3) Recirculating hom: Piv nrog rau hom qauv, nws tshem tawm lub nplhaib iav sab hauv thiab ntxiv cov qauv cam nplhaib, nws txoj haujlwm zoo ib yam li lub pob ntsia hlau rov qab, txhawm rau ua kom cov menyuam rov qab mus rau qhov chaw pib tom qab tig. nyob rau hauv txiv ntseej rau ib lub lim tiam.Cov yam ntxwv ntawm lub structuralrecirculating planetary menyuam ntsia hlaunce tus naj npawb ntawm cov xov sib koom ua ke, yog li nws muaj kev nruj nruj thiab muaj peev xwm thauj khoom loj, thiab feem ntau yog siv rau hauv cov ntawv thov uas yuav tsum muaj kev nruj nruj, muaj peev xwm thauj khoom siab, thiab siab precision, xws li cov cuab yeej kho mob, cov cuab yeej kho qhov muag, thiab lwm yam. .Qhov tsis zoo yog tias nws cov qauv cam nplhaib yuav tsim kev co, muaj teeb meem suab nrov;
(4) Hom sib txawv: Piv nrog rau hom qauv, lub nplhaib iav sab hauv raug tshem tawm thiab tsis muaj iav ntu ntawm cov menyuam.Cov yam ntxwv ntawm kev sib txawv planetary roller ntsia hlau ua rau nws tuaj yeem tau txais cov hlau lead me me, uas yog tsim rau cov ntawv thov nrog qhov sib kis loj dua thiab muaj peev xwm nqa tau ntau dua.Txawm li cas los xij, thaum nws txav mus, cov xov yuav tsim cov zawv zawg tshwm sim, uas yog nquag hnav hauv qhov hnyav, ua rau poob ntawm qhov tseeb, txo kev ntseeg siab thiab lwm yam teeb meem.
Ib tug inverted cov menyuam ntsia hlau nyob rau hauv ib tug linear actuator
Planetary roller ntsia hlau nkag mus yuav tsum tau nce, hloov ib feem ntawm lub teb ntawm pob screws thiab hydraulic kis:
(1) Piv nrog rau kev sib kis ntawm cov pob ntsia hlau, lub ntiaj teb cov menyuam screws muaj lub peev xwm nqa tau zoo dua, tuaj yeem siv rau hauv kev ua haujlwm nyuaj thiab hnyav, lub neej ntev thiab lwm yam zoo, yuav tsum tau siv rau hauv kev siv tshuab, tshuab hluav taws xob. cylinders thiab lwm yam xwm txheej;
(2) Raws li lub planetary roller ntsia hlau precision kis qauv, kom kov yeej cov tsoos hydraulic kis tau tus mob nyob rau hauv ib puag ncig adaptability, tsis tshua muaj kev cia siab, siv tsis zoo tu thiab lwm yam shortcomings, yuav tsum tau hloov ib feem ntawm scene hydraulic kis tau tus mob.
