Ii-actuator ze-electromechanical ziza kwiindidi ezininzi, kunye neendlela eziqhelekileyo zokuqhubaizikrufu zokukhokela, izikrufu zebhola, kunye nezikrufu zerola. Xa umyili okanye umsebenzisi efuna ukutshintsha ukusuka kwi-hydraulics okanye i-pneumatics ukuya kwintshukumo ye-electromechanical, i-roller screw actuators idla ngokuba lolona khetho lungcono. Banikezela ngeempawu zokusebenza ezifaniswayo kwi-hydraulics (amandla aphezulu) kunye ne-pneumatics (isantya esiphezulu), kwinkqubo enzima kakhulu.
A i-roller screwithatha indawo yeebhola ezijikelezayo ngeerola ezinemisonto.Intongomane inomsonto wangaphakathi ohambelana nomsonto wesikrufu. Iirola zicwangciswe kwi-a uqwalaselo lweplanethi kwaye bobabini bajikelezisa amazembe abo kunye ne-orbit ejikeleze i-nut.Iziphelo ze-roller zinamazinyo ukuze zibe ne-mesh kunye namakhonkco alungelelanisiweyo ekupheleni kwe-nut, ukuqinisekisa ukuba ii-roller zihlala kulungelelaniso olugqibeleleyo, ngokuhambelana ne-axis ye-screw. kunye namantongomane.
I-roller screw luhlobo lwe-screw drive oluthatha indawo yeebhola ezijikelezayo kunye ne-threaded rollers. Iziphelo ze-roller zi-toothed kwi-mesh kunye namakhonkco alungelelanisiweyo kwinqanaba ngalinye le nut. Iirola zombini zijikeleza kwii-axes zazo kwaye zijikeleze i-nut, kubume beplanethi. (Kungenxa yoko le nto izikrufu zerola zikwabizwa ngokuba zizikrufu zerola zeplanethi.)
Ijiyometri ye-roller screw ibonelela ngokubonakalayo ngakumbi amanqaku oqhagamshelwano kunokuba kunokwenzeka ngeibhola screw. Oku kuthetha ukuba izikrufu eziqengqelekayo zinomthamo ophezulu oguqukayo womthwalo kunye nobungqongqo kunezikrufu zebhola ezinobungakanani obufanayo. Kwaye imisonto emihle (i-pitch) ibonelela ngenzuzo ephezulu yomatshini, oku kuthetha ukuba i-torque encinci iyafuneka kumthwalo onikiweyo.
Inzuzo yoyilo oluphambili lwe-screws ye-roller (ezantsi) phezu kwe-screws yebhola (phezulu) kukukwazi ukuquka amanqaku amaninzi oqhagamshelwano kwindawo enye.
Ngenxa yokuba iirola zazo ezithwele imithwalo aziqhagamshelani, izikrufu eziqengqelekayo zinokuhamba ngesantya esiphezulu kunezikrufu zebhola, ekufuneka zijongane namandla kunye nobushushu obuveliswa ziibhola ezingqubana enye nenye kunye ne-recirculation end caps.
Izikrufu zerola eziguqulweyo
Uyilo olujijelweyo lusebenza kumgaqo ofanayo nesikrufu esiqhelekileyo sokuqengqeleka, kodwa indongomane ijikwa ngaphakathi-ngaphandle. Ke, igama elithi "inverted roller screw." Oku kuthetha ukuba i-roller ijikeleza i-screw (endaweni ye-nut), kwaye i-screw ifakwe kuphela kwindawo apho ii-roller zijikeleza khona. I-nut, ke ngoko, iba yindlela yokumisela ubude, ngoko ke iqhelekile kunentongomane kwisikrufu esiqhelekileyo sokuqengqeleka. Nokuba i-screw okanye i-nut ingasetyenziselwa intonga yokutyhala, kodwa uninzi lwezicelo ze-actuator zisebenzisa isikrufu ngale njongo.
Ukwenziwa kwesikrufu esijijekileyo sinikezela ngomngeni wokudala imisonto echanekileyo yangaphakathi yentongomane kubude obude, nto leyo ethetha ukuba kusetyenziswa indibaniselwano yeendlela zomatshini. Isiphumo kukuba iintambo zithambile, kwaye ngoko ke, ukulinganiswa komthwalo we-screws ye-roller inverted iphantsi kunezikhonkwane eziqhelekileyo. Kodwa izikrufu ezijijekileyo zinenzuzo yokuba zixinene ngakumbi.
