Rack uye Pinion actuator
Chii chinonzi Rack uye Pinion actuator?
Rack-uye-pinion pneumatic actuators, anonziwo mashoma ekutenderera masilinda, ma rotary actuators anoshandiswa kutenderedza, kuvhura, kuvhara, kusanganisa, kutenderedza, kuisa chinzvimbo, kutungamira uye mamwe akawanda mabasa emuchina anosanganisira kutenderera kwakaganhurirwa.Aya ma actuators anowanzo shandiswa kuita otomatiki yekota-turn mavharuvhu, senge bhora kana butterfly mavharuvhu.
Pneumatic rack-uye-pinion actuatorsshandura simba remhepo yakadzvanyirirwa uchishandisa silinda yepneumatic kuenda kune inotenderera inotenderera.Iyo yakachena, yakaoma, uye yakagadziriswa gasi inodiwa neiyi actuator inopiwa kuburikidza nepakati compressed air station, iyo inowanzo tsigira huwandu hwepneumatic zvishandiso mu process system.
Mamiriro makuru eRack uye Pinion actuator
Mukuenzanisa nemagetsi avo emagetsi counter parts,Rack uye pinion actuators kazhinji dzinogara kwenguva refu, dzinokodzera zvirinani kunharaunda dzine njodzi uye dzinodhura.Uye zvakare, ivo vanowanzoda kushoma kugadzirisa uye kupa yakakwira torque mukuenzanisa nehukuru hwavo.
Tekinoroji yehunyanzvi hweRack uye Pinion actuator
Single rack vs. dual rack dhizaini
Rack-and-pinion actuators inopa huwandu hwakakura hwe torque uye kutenderera zvichienzaniswa nedzimwe nzira dzekushandura mutsara simba kune inotenderera torque.Iyo ine yakakwira mechaniki kunyatsoshanda uye torques avanokwanisa kuburitsa kubva kune akati wandei maNm kusvika kune akawanda zviuru zveNm.
Nekudaro, imwe inogona kudzoka kumashure kweiyo rack-uye-pinion dhizaini ndeye backlash.Kudzokera shure kunoitika kana rack uye pinion magiya asina kunyatso kurongeka uye pane kamukana kadiki pakati pega yega yekubatanidza.Iyi misalignment inogona kukonzera kupfeka pamagiya panguva yehupenyu hweiyo actuator, iyo inozowedzera backlash.
A double rack unit inoshandisa peya yeraki kumativi akatarisana epioni.Izvi zvinobatsira kubvisa backlash nekuda kwesimba rekupikisa uye zvakare inopeta kaviri torque yekubuda kweyuniti uye inowedzera mashandiro emuchina weiyo system.Mune kaviri acting actuator inoratidzwa muMufananidzo 3, makamuri maviri ari kumativi akazadzwa nemhepo yakamanikidzwa, iyo inosundira mapistoni pakati uye kudzosera mapiston panzvimbo yekutanga, kamuri iri pakati inomanikidzwa.
Function
Rack-uye-pinion pneumatic actuators inogona kunge iri imwechete-kuita kana kaviri-kuita.Izvo zvakare zvinogoneka kuti aya ma actuators ape akawanda anomira.
Kuita mumwechete vs. kuita kaviri
Mune imwechete-acting actuator, mhepo inongopihwa kune rimwe divi repiston uye inotarisira kufamba kwepiston munzira imwe chete.Kufamba kwepiston kune rumwe rutivi kunoitwa ne mechanical spring.Single-acting actuators inochengetedza mhepo yakamanikidzwa, asi ita basa munzira imwe chete.A downside of single-acting cylinders ndiko kusapindirana kwekubuda kwesimba kuburikidza nekuzara kwakazara nekuda kwekupikisa simba rechirimo.Mufananidzo 4 unoratidza imwe-inoita kaviri-rack pneumatic rotary actuator.
Mune kaviri-acting actuator, mweya unopihwa kumakamuri pamativi ese episton (s).Mhepo yakakwirira kune rumwe rutivi inogona kutyaira piston (s) kune rimwe divi.Kaviri-acting actuator inoshandiswa kana basa richida kuitwa mumativi ese.Mufananidzo 5 unoratidza kaviri-inoita kaviri-rack pneumatic rotary actuator.
Imwe yemabhenefiti e-double acting cylinders ndiyo inogara ichiburitsa simba kuburikidza neazere kutenderera renji.Izvo zvipingamupinyi zvemasilinda-anoita kaviri ndiko kudiwa kwavo kwemhepo yakatsikirirwa yekufambisa mumativi ese uye kushaikwa kwenzvimbo yakatsanangurwa kana simba kana kumanikidzwa kutadza.
Multiple positioning
Mamwe rack-and-pinion actuators anokwanisa kumira panzvimbo dzakawanda kuburikidza nehuwandu hwekutenderera nekudzora kudzvanywa pazviteshi.Nzvimbo dzekumira dzinogona kunge dziri mune chero kutevedzana, zvichiita kuti iyo actuator ikwanise kupfuudza nzvimbo yepakati-yepakati yekumira.
Mabhaudhi anomisa kufamba
Mabhaudhi ekufamba ari padivi remuviri weactuator (sezvinoonekwa muMufananidzo 6) uye bvumidza kugadziriswa kwenzvimbo dzekupedzisira dzepistoni nekudzikamisa kutenderera kwepinion giya kubva mukati.Paunenge uchiisa actuator, tyaira mune ese mabhaudhi ekufamba kusvika abata chivharo chekufamba.Ramba uchikwenya bhaudhi rekuruboshwe rekufamba kusvikira pinion slot ichioneka kumusoro ichitenderera kuenda panzvimbo inofambirana nehurefu hwemuviri weactuator.
Chigadzirwa Chishandiso: chikamu shandura magetsi actuator
Nekuda kwekugara kwavo torque kubuda,Rack uye pinion actuatorsanowanzo shandiswa uye kazhinji akasarudzika maitiro epneumatic actuators emavharuvhu.Iyo inoshandiswa kusanganisa, kurasira, kudya kwepakati, kutenderera kunoramba kuripo, kutendeuka, kuisa, kumisa, kusimudza, kuvhura nekuvhara uye kutendeuka.Aya ma actuators anoshandiswa kune akasiyana mashandiro emuchina muindasitiri yesimbi, kubata zvinhu, mashandiro emugungwa, midziyo yekuvaka, muchina wemigodhi, uye hydraulic power steering.
