Electromechanical actuators inouya mumhando dzakawanda, ine akajairika madhiraivha maitiro arilead screws, screws dzebhora, nemaroller screws. Kana mugadziri kana mushandisi achida kushandura kubva ku hydraulics kana pneumatics kuenda ku electromechanical motion, roller screw actuators kazhinji ndiyo yakanakisa sarudzo. Vanopa maitiro akafanana ekuita kune hydraulics (yakakwirira simba) uye pneumatics (yakanyanya kumhanya), mune isina kuoma sisitimu.
A roller screwinotsiva mabhora anodzokororwa ane threaded rollers.Nzungu ine shinda yemukati inofanana neshinda yescrew. Ma rollers akarongwa mu a magadzirirwo epuraneti uye ese ari maviri anotenderera pamatemo adzo uye anotenderera achitenderedza nati. Migumo yema rollers ane mazino kuti mesh negiya mhete pamucheto wega wega nati, kuve nechokwadi chekuti ma roller anoramba ari mugwara rakakwana, anoenderana neaxis ye screw. uye nut.
A roller screw imhando ye screw drive inotsiva mabhora anotenderedzwa ane threaded rollers. Mheto dzema rollers dzinoiswa mazino kuti dziite mesh ne geared mhete pamucheto wega wega we nut. Iwo ma roller ese ari maviri anotenderera pamasanhu avo uye anotenderera achitenderedza nati, mukugadzirisa kwepuraneti. (Ndosaka ma roller screws anonziwo mapuraneti roller screws.)
Iyo geometry yeroller screw inopa zvakanyanya kuwanda mapoinzi kupfuura anogoneka neabhora sikuruu. Izvi zvinoreva kuti ma roller screws anowanzo kuve nepamusoro pesimba rekutakura zvinhu uye kusimba pane zvakafanana saizi yebhora screws. Uye tambo dzakanaka (pitch) inopa yakakwira mechaniki mukana, zvichireva kuti shoma yekuisa torque inodiwa kune wakapihwa mutoro.
Iyo yakakosha dhizaini mukana we roller screws (pazasi) pamusoro pebhora screws (pamusoro) kugona kuve neakawanda mapoinzi ekusangana munzvimbo imwechete.
Nekuda kwekuti ma roller avo anotakura mitoro haabatane, ma roller screws anowanzo famba nekumhanya kwakakwira kupfuura bhora remasikiru, ayo anofanirwa kutarisana nemasimba uye kupisa kunokonzerwa nemabhora ari kudhumhana uye nemakepisi ekupedzisira.
Inverted roller screws
Iyo inverted dhizaini inoshanda pamusimboti mumwechete seyakajairwa roller screw, asi nati inoshandurwa mukati-kunze. Saka, izwi rekuti "inverted roller screw." Izvi zvinoreva kuti ma rollers anotenderera akatenderedza screw (panzvimbo ye nut), uye screw inosungirirwa chete munzvimbo iyo ma rollers anotenderera. Iyo nati, saka, inova iyo yekumisikidza kureba, saka inowanzorebesa kupfuura nati pane yakajairwa roller screw. Ingave screw kana nati inogona kushandiswa kutsvimbo yekusundidzira, asi akawanda actuator maapplication anoshandisa screw nechikonzero ichi.
Kugadzira siruu yakapindirwa kunopa dambudziko rekugadzira shinda dzemukati chaidzo dzenati neurefu hwakareba, zvinoreva kuti musanganiswa wemitoo yekugadzira unoshandiswa. Mhedzisiro yacho ndeyekuti tambo dzakapfava, uye nekudaro, miyero yekuremerwa yeinverted roller screws yakaderera pane yeyakajairwa roller screws. Asi inverted screws ine bhenefiti yekuve yakawanda compact.
