Ama-actuator e-electromechanical aza ngezinhlobo eziningi, kunezindlela zokushayela ezivamileizikulufo zokuhola, izikulufu zebhola, nezikulufu zamarola. Uma umklami noma umsebenzisi efuna ukushintsha ukusuka ku-hydraulics noma i-pneumatics ukuya ekunyakazeni kwe-electromechanical, ama-roller screw actuators ngokuvamile ayinketho engcono kakhulu. Banikeza izici zokusebenza eziqhathanisekayo kuma-hydraulics (amandla aphezulu) kanye ne-pneumatics (isivinini esikhulu), ohlelweni oluyinkimbinkimbi kancane.
A i-roller screwishintsha amabhola ajikelezayo ngamarola anentambo.Inadi linentambo yangaphakathi efana nentambo yesikulufu. Amarola ahlelwe ngo-a ukumiswa kweplanethi futhi womabili azungeza izimbazo zawo futhi azungeza inathi.Iziphetho zamarola zinamazinyo ukuze zihlangane nezindandatho ezigayelwe ekugcineni kwentongomane, okuqinisekisa ukuthi amarola ahlala ekuqondaneni okuphelele, ngokuhambisana ne-eksisi yesikulufu. kanye namantongomane.
I-roller screw uhlobo lwe-screw drive ethatha indawo yamabhola ajikelezayo ngamarola anentambo. Iziphetho zama-roller zinamazinyo ukuze zibe nezikhala ezinamagiya ekugcineni kwenati. Amarola womabili azungeza izimbazo zawo futhi azungeza inathi, ekucushweni kweplanethi. (Yingakho izikulufu ze-roller nazo zibizwa ngokuthi izikulufu ze-roller zeplanethi.)
Ijiyomethri yesikulufu serola inikeza amaphuzu okuxhumana amaningi kakhulu kunangendlela okungenzeka ngayo nge-isikulufu sebhola. Lokhu kusho ukuthi izikulufu zamarola ngokuvamile zinamandla okulayisha ashukumisayo aphezulu kanye nokuqina kunezikulufu zebhola ezinosayizi ofanayo. Futhi imicu emihle (iphimbo) ihlinzeka ngenzuzo ephezulu yomshini, okusho ukuthi itorque encane yokufaka iyadingeka kumthwalo onikeziwe.
Inzuzo yedizayini eyinhloko yezikulufi zamarola (phansi) phezu kwezikulufu zebhola (phezulu) yikhono lokuqukatha izindawo eziningi zokuxhumana endaweni efanayo.
Ngenxa yokuthi amarola azo athwala imithwalo awaxhumani, izikulufu zamarola ngokuvamile zingahamba ngesivinini esiphezulu kunezikulufu zebhola, okumele zibhekane namandla nokushisa okukhiqizwa amabhola angqubuzanayo kanye namakepisi okugcina aphinde azungeza.
Izikulufu zamarola ahlanekezelwe
Idizayini ehlanekezelwe isebenza ngomgomo ofanayo njengesikulufu esijwayelekile serola, kodwa inathi liguqulelwa ngaphakathi-ngaphandle. Ngakho-ke, igama elithi "inverted roller screw." Lokhu kusho ukuthi ama-roller azungeza isikulufu (esikhundleni se-nati), futhi isikulufu sifakwa kuphela endaweni lapho amarola azungeza khona. Ngakho-ke, inathi liba yindlela yokunquma ubude, ngakho-ke lide kakhulu kunenadi eliku-screw roller evamile. Kungaba isikulufu noma inathi lingasetshenziselwa i-push rod, kodwa izinhlelo zokusebenza eziningi ze-actuator zisebenzisa isikulufu ngale njongo.
Ukwenziwa kwesikulufu esihlanekezelwe serola kuletha inselele yokudala imicu yangaphakathi enembe kakhulu yamantongomane ngobude obude ngokuqhathaniswa, okusho ukuthi inhlanganisela yezindlela zomshini ziyasetshenziswa. Umphumela uba ukuthi izintambo zithambile, ngakho-ke, izilinganiso zomthwalo wezikulufu ezihlanekezelwe ziphansi kunezikulufu ezijwayelekile zamarola. Kodwa izikulufu ezihlanekezelwe zinenzuzo yokuba ziminyene kakhulu.
