Izikrufu zerolazijongwa ngokubanzi kuyilo oluqhelekileyo lweplanethi, kodwa kukho iinguqulelo ezininzi, kubandakanywa umahluko, ukujikeleza, kunye neenguqulelo eziguqulweyo. Uyilo ngalunye lubonelela ngeenzuzo ezizodwa ngokubhekiselele kwizakhono zokusebenza (umthamo womthwalo, i-torque, kunye nokubeka indawo), kodwa inzuzo ephambili ye-screw roller inverted yikhono layo lokudityaniswa ngokulula kwii-activators kunye nezinye ii-subassemblies.
Khumbula loo mgangathoizikrufu zerola(ekwaziwa ngokuba zizikrufu zeplanethi yerola) sebenzisa iirola ezinemisonto ezinamazinyo ekupheleni kwerola ukubandakanya iringi yegiya kwisiphelo ngasinye sendongomane. Kwi-screws roller inverted, imisebenzi ye-screw kunye ne-nut iyatshintshwa okanye iguqulwe. I-nut ingumbhobho ene-ID ene-threaded endaweni yokuba ibe yinde ngokwaneleyo ukulungiselela i-roller kunye ne-mating gear rings, ubude bokuhamba kwe-nut. Kwaye i-screw shaft-kunokuba ithungwe ngobude bayo bonke-ithungelwe nje ixesha elide ngokwaneleyo ukuba lilingane nobude berola.
IguqulweRngaphezuluSabasebenzi
Ngeisikrufu eso esijijekileyo, ubude be-nut bumisela i-stroke, kwaye inxalenye ye-threaded ye-screw ide kuphela njenge-roller.
Ngoko xa i-screw shaft ijikeleza, endaweni ye-nut kunye ne-roller eguqulela ngobude be-screw, ii-roller zihlala zimile kwi-screw (oko kukuthi, ii-roller kunye ne-nut azihambi ngobude be-screw). Ngokuchasene noko, ukuguqula i-screw shaft kubangela ukuba ii-roller kunye ne-screw ziguqulele ngobude be-nut. Kungenjalo, isikrufu serola esijikiweyo singasetyenziselwa ukuqhuba i-nut kunye nokugcina isikrufu (kunye neerola) simile.
Ngenxa yokuba iringi yegiya eqhele ukuhlala ekupheleni kwe nut ngoku isekupheleni kwenxalenye ephothiweyo yesikrufu, idiameter ye nut inokwenziwa ibe ncinci kancinane kunaleyo yeplanethi enobungakanani obulinganayo.i-roller screw. Ngelixa ukwenza iintambo ngaphakathi kumzimba omde we nut kunokuba nzima, izikrufu zerola eziguquliweyo zifuna iiqalo ezimbalwa kunezikrufu eziqhelekileyo zeplanethi yerola, oku kuthetha ukuba banokusebenzisa imisonto emikhulu, ethi yona ibonelele ngomthwalo oPhezulu kunoyilo oluqhelekileyo.
Izikrufu zerola eziguquliweyo zilungele ii-actuator zesitayile se-pushrod, apho i-pushrod iye yanda kwaye irhoxa kwizindlu ze-actuator. Kwaye ngenxa yokuba inxalenye enkulu ye-screw shaft ayifundwanga (kuphela inxalenye apho i-roller ikhona), i-shaft ingenziwa ngokwezifiso ukuze ihambelane noyilo lwe-actuator kunye neemfuno zesicelo. Uyilo olujijelweyo lukwenza kube lula kubavelisi be-actuator ukufaka umazibuthe kwii-roller screwnut kwaye uyisebenzise njengerotor yendibano edibeneyo yesikrufu semoto.
