Ama-actuators e-electromechanical eza ngezinhlobonhlobo eziningi, ngezindlela ezijwayelekile zokushayelaukuhola izikulufo, Izikulufo zebhola, nezikulufa ze-roller. Lapho umklami noma umsebenzisi efuna ukuguqulwa kusuka kuma-hydraulics noma ama-pneumatics kuya ku-electromechanical motion, ama-roller screw actuators ajwayele ukukhetha okuhle kakhulu. Bahlinzeka ngezimpawu zokusebenza eziqhathanisekayo kuma-hydraulics (amandla aphezulu) nama-pneumatics (ijubane eliphezulu), ohlelweni oluncane oluyinkimbinkimbi.
A isikulufa we-rollerEsikhundleni amabhola aphindaphindwayo ane-rolling roller.I-nati enentambo yangaphakathi efanisa intambo yesikulufa. Ama-roller ahlelwe ku Ukucushwa kweplanethi futhi bobabili bobabili ama-axes abo bese ujikeleza ama-nati.Iziphetho zama-roller zigcwele izindandatho ngakunye kwe-nati ngakunye kwe-nati ngakunye, ukufana ne-axis yesikulufa kanye nati.
Isikulufa se-Roller luhlobo lwe-screw drive ethatha indawo amabhola aphindaphindwayo ngama-roller threaded. Imikhawulo yama-roller ifakwe ku-mesh ngezindandatho ezihlongoziwe ekugcineni ngakunye kwe-nati. Ama-roller womabili athinta izimbazo zawo bese ejikeleza izungeze nati, ekucushweni kweplanethi. (Lokhu yingakho izikulufo ze-roller nazo zibizwa ngokuthi izikulufo zeplanethi roller.)
I-geometry ye-roller screw inikeza amaphuzu amaningi okuxhumana kunalokho okungenzeka ngeisikulufa sebhola. Lokhu kusho ukuthi ama-roller screws ajwayele ukuba namakhono ashukumisayo anamandla okulayisha nokuqina kunezikulufo ezilinganayo zebhola. Futhi imicu emihle (i-pitch) ihlinzeka ngenzuzo ephakeme yemishini, okusho ukuthi i-torque yokufaka ephansi iyadingeka kumthwalo onikezwe.
Inzuzo ebalulekile yokuklama kwama-roller screws (phansi) ngaphezulu kwezikulufo zebhola (phezulu) yikhono lokuqukatha amaphuzu okuxhumana amaningi esikhaleni esifanayo.
Ngoba ama-roller abo abaphethe umthwalo awaxhumana nawo, ama-roller screws ajwayele ukuhamba ngesivinini esiphakeme kunezikulufo zebhola, okudingeka abhekane namandla nokushisa okukhiqizwe amabhola ahlanganiswe nomunye futhi aphetha ama-cap.
Izikulufo ezi-Roller ezingenisiwe
Idizayini ehlanekezelwe isebenza ngomgomo ofanayo nesikulufa esijwayelekile se-roller, kepha nati empeleni iphendulwe ngaphakathi. Ngakho-ke, igama elithi "inverned roller screw." Lokhu kusho ukuthi ama-roller ajikeleza isikulufa (esikhundleni se-nati), futhi isikulufa senziwe gazinga kuphela endaweni lapho ama-rollers amji. Ngakho-ke, in nati iba ngumshini wokunquma ubude, ngakho-ke imvamisa isikhathi eside kune-nati kwi-roller screw ejwayelekile. Kuphakathi isikulufa noma i-nati ingasetshenziselwa induku ye-push, kepha izinhlelo eziningi ze-actuator zisebenzisa isikulufa kule nhloso.
Ukwenziwa kwe-Heller Roller Screw kuveza inselelo yokwakha imicu yangaphakathi eqondile ye-nati ngaphezulu kobude obude, okusho ukuthi kusetshenziswa inhlanganisela yezindlela zemichilo. Umphumela uba ukuthi imicu ithambile, futhi ngenxa yalokho, izilinganiso zomthwalo wezikulungi ze-roller ezingenisiwe ziphansi kunezikulufo ezijwayelekile ze-roller. Kepha izikulufo ezihlanekezelwe zinenzuzo yokuba yinkimbinkimbi kakhulu.
