I-Rack kunye nePinion actuator
Yintoni iRack kunye nePinion actuator?
I-Rack-and-pinion actuators ye-pneumatic, ezikwabizwa ngokuba zii-cylinders zokujikeleza okulinganiselweyo, zii-activators ezijikelezayo ezisetyenziselwa ukujika, ukuvula, ukuvala, ukuxuba, uku-oscillating, ukubeka indawo, ukuqondisa kunye neminye imisebenzi emininzi yomatshini ebandakanya ukujikeleza okuthintelweyo.Ezi actuator nazo zihlala zisetyenziselwa ukuzenzekela kweevalvu zekota, njengebhola okanye iivalve zebhabhathane.
I-Pneumatic rack-and-pinion actuatorsguqula amandla omoya ocinezelekileyo ngokusebenzisa isilinda somoya kwintshukumo ejikelezayo ejikelezayo.Irhasi ecocekileyo, eyomileyo, kunye necutshungulwayo efunwa yile actuator inikezelwa ngesikhululo somoya esicinezelekileyo, esihlala sixhasa uluhlu lwezixhobo zomoya kwinkqubo yenkqubo.
Iimpawu eziphambili zeRack kunye nePinion actuator
Xa kuthelekiswa neendawo zabo zokubala zombane,I-Rack kunye ne-pinion actuators Zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala zihlala khona kwaye zinexabiso eliphantsi.Ukongeza, bahlala befuna ukugcinwa okuncinci kunye nokubonelela nge-torque ephezulu xa kuthelekiswa nobukhulu babo.
Iinkcukacha zobuchwephesha beRakhi kunye nePinion actuator
Irekhi enye vs. uyilo lwerekhi ezimbini
I-Rack-and-pinion actuators zibonelela ngoluhlu olubanzi lwetorque kunye nokujikeleza xa kuthelekiswa nezinye iindlela zokuguqula ukuguqula amandla omgca kwitorque ejikelezayo.Inokusebenza kakuhle koomatshini kunye neetorque ezikwaziyo ukuvelisa ukusuka kwisibini se-Nm ukuya kumawaka amaninzi e-Nm.
Nangona kunjalo, enye i-drawback enokubakho yoyilo lwe-rack-and-pinion kukubuyela umva.Ukubuyisela umva kwenzeka xa i-rack kunye ne-pinion gears ingahambelani ngokupheleleyo kwaye kukho isithuba esincinci phakathi koqhagamshelwano olulungiselelwe.Oku kungahambi kakuhle kunokubangela ukunxiba kwiigiya ngexesha lomjikelo wobomi be-activator, nto leyo eyandisa umva.
Irekhi ephindwe kabini isebenzisa iirakhi kumacala ahlukeneyo epiyoni.Oku kunceda ukuphelisa umva ngenxa ye-counter force kwaye iphinda iphindwe kabini i-torque yeyunithi kunye nokwandisa ukusebenza kakuhle komatshini wenkqubo.Kwi-activator ephindwe kabini eboniswe kuMzobo 3, amagumbi amabini emacaleni azaliswe ngumoya ocinezelekileyo, otyhala iipistons embindini kunye nokubuyisela ipiston kwindawo yokuqala, igumbi eliphakathi lixinzeleleke.
Umsebenzi
I-Rack-and-pinion actuators ye-pneumatic inokuba yinto enye okanye ephindwe kabini.Kuyenzeka ukuba ezi actuator zibonelele ngeendawo zokumisa ezininzi.
Ukwenza umntu omnye vs. ukwenza kabini
Kwi-activator eyodwa, umoya unikezelwa kuphela kwicala elinye lepiston kwaye unoxanduva lokuhamba kwepiston kwicala elinye kuphela.Ukuhamba kwepiston kwicala elichaseneyo kwenziwa ngumthombo womatshini.Ii actuators ezibambeleyo zonga umoya oxinanisiweyo, kodwa zenza umsebenzi kwicala elinye kuphela.I-downside ye-cylinders ye-single-acting force i-output force force ngokusebenzisa i-stroke epheleleyo ngenxa ye-spring force echasayo.Umzobo we-4 ubonisa i-actuator ye-rotary ye-pneumatic ene-double-acting single-acting.
Kwi-activator esebenza kabini, umoya unikezelwa kumagumbi kumacala omabini episton.Uxinzelelo lomoya oluphezulu kwelinye icala linokuqhuba ipiston (s) kwelinye icala.Ii-activators ezisebenza kabini zisetyenziswa xa umsebenzi kufuneka wenziwe kumacala omabini.Umzobo 5 ubonisa i-double-rack ye-pneumatic rotary actuator.
Enye yeenzuzo zeesilinda ezisebenza kabini yi-force ephuma rhoqo ngokusebenzisa uluhlu olupheleleyo lokujikeleza.Ukungaphumeleli kweesilinda eziphindwe kabini ziyimfuno yazo yomoya oxinzelelweyo wokunyakaza kwiindlela zombini kunye nokungabikho kwesithuba esichaziweyo kwimeko yokungaphumeleli kwamandla okanye uxinzelelo.
Ukubekwa kwiindawo ezininzi
Ezinye i-rack-and-pinion actuators ziyakwazi ukumisa kwiindawo ezininzi ngokusebenzisa uluhlu lokujikeleza ngokulawula uxinzelelo kumazibuko.Iindawo zokumisa zinokuba kulo naluphi na ulandelelwano, okwenza kube lula ukuba i-activator iphumelele ngokukhethayo indawo yokumisa ephakathi.
Iibholiti zokumisa ukuhamba
Iibholiti zokumisa ukuhamba zisecaleni lomzimba we-actuator (njengoko kuboniswe kwi-Figure 6) kwaye uvumele ukulungiswa kwezikhundla zokuphela kweepiston ngokunciphisa ukujikeleza kwe-pinion gear ukusuka ngaphakathi.Xa ufaka i-actuator, qhuba kuzo zombini iibholiti zokumisa de uqhagamshelane nekepusi yokumisa uhambo.Qhubekeka ngokujija ibholithi yokumisa yokuhamba ekhohlo de ipinion slot ibonakale phezulu ijikelezisa ukuya kwindawo engqamene nobude bomzimba we actuator.
Isicelo seMveliso: inxalenye yokuguqula i-actuator yombane
Ngenxa yokuphuma kwabo rhoqo kwetorque,I-Rack kunye ne-pinion actuatorszisetyenziswa rhoqo kwaye zihlala isimbo esikhethwayo se-pneumatic actuators kwiivalvu.Zisetyenziselwa ukuxuba, ukulahla, ukutya okuphakathi, ukujikeleza ngokuqhubekayo, ukujika, ukubeka indawo, ukujikeleza, ukuphakamisa, ukuvula nokuvala kunye nokujika.Ezi actuators zisetyenziselwa imisebenzi eyahlukeneyo yoomatshini kwishishini lentsimbi, ukuphatha izinto, ukusebenza elwandle, izixhobo zokwakha, oomatshini basemigodini, kunye nokulawula amandla okwenziwa ngolwelo.
