Isixhobo sokuqhuba iRack kunye nePinion
Yintoni i-Rack kunye ne-Pinion actuator?
Ii-actuators ze-pneumatic ze-rack-and-pinion, ezikwabizwa ngokuba zii-limited rotation cylinders, zii-rotary actuators ezisetyenziselwa ukujika, ukuvula, ukuvala, ukuxuba, ukujika, ukubeka kwindawo, ukuqhuba kunye neminye imisebenzi emininzi yoomatshini equka ukujikeleza okulinganiselweyo. Ezi actuators zihlala zisetyenziselwa ukwenza ii-automation zee-quarter-turn valves, njengee-ball okanye ii-butterfly valves.
Ii-actuators ze-rack-and-pinion ze-pneumaticGuqula amandla omoya ocinezelweyo nge-cylinder ye-pneumatic ibe yintshukumo ejikelezayo ejikelezayo. Igesi ecocekileyo, eyomileyo, necutshungulwayo efunekayo yile actuator inikezelwa ngesikhululo somoya esicinezelweyo esiphakathi, esihlala sixhasa uluhlu lwezixhobo ze-pneumatic kwinkqubo yenkqubo.
Iimpawu eziphambili ze-Rack kunye ne-Pinion actuator
Xa kuthelekiswa neenxalenye zabo zekhawuntara yombane,Ii-actuators ze-rack kunye ne-pinion ngokubanzi zihlala ixesha elide, zilungele ngcono iindawo ezinobungozi kwaye azibizi kakhulu. Ukongeza, zihlala zifuna ulondolozo oluncinci kwaye zibonelela nge-torque ephezulu xa kuthelekiswa nobukhulu bazo.
Iinkcukacha zobugcisa ze-Rack kunye ne-Pinion actuator
Uyilo lwe-rack enye xa kuthelekiswa noyilo lwe-rack ezimbini
Ii-actuators ze-rack-and-pinion zibonelela ngoluhlu olubanzi lwe-torque kunye nokujikeleza xa kuthelekiswa nezinye iindlela zokuguqula ukuguqula amandla angqameneyo abe yi-torque ejikelezayo. Isebenza kakuhle kakhulu kwaye ii-torque ezikwaziyo ukuzenza ziqala kwi-Nm ezimbalwa ukuya kumawaka amaninzi e-Nm.
Nangona kunjalo, enye ingxaki enokubakho yoyilo lwe-rack-and-pinion yi-backlash. I-backlash yenzeka xa ii-rack kunye nee-pinion gears zingahambelananga ngokupheleleyo kwaye kukho umsantsa omncinci phakathi koqhagamshelo ngalunye lwe-gear. Oku kungahambi kakuhle kunokubangela ukuguguleka kweegiya ngexesha lobomi be-actuator, nto leyo ebangela ukuba i-backlash ikhule.
Iyunithi yerakhi ephindwe kabini isebenzisa iirakhi ezimbini kumacala ahlukeneyo e-pinion. Oku kunceda ekupheliseni umva ngenxa yamandla achaseneyo kwaye kwandisa i-torque yokukhupha yeyunithi kwaye kwandisa ukusebenza kakuhle kwenkqubo. Kwi-actuator esebenzayo kabini eboniswe kuMfanekiso 3, amagumbi amabini emacaleni azaliswe ngumoya oxinzelelweyo, otyhala ii-pistons embindini kwaye ukubuyisela ii-pistons kwindawo yokuqala, igumbi elisembindini nalo liyaxinzelelwa.
Umsebenzi
Ii-actuators ze-rack-and-pinion pneumatic zinokuba ze-single-acting okanye ze-double-acting. Kunokwenzeka ukuba ezi actuators zinike iindawo zokumisa ezininzi.
Ukulingisa komntu omnye xa kuthelekiswa nokudlala kabini
Kwi-actuator esebenza ngesinye, umoya unikezelwa kwicala elinye le-piston kwaye unoxanduva lokuhamba kwe-piston kwicala elinye kuphela. Ukushukuma kwe-piston kwicala elichaseneyo kwenziwa yi-mechanical spring. Ii-actuators ezisebenzayo ngesinye zigcina umoya ocinezelweyo, kodwa zenza umsebenzi kwicala elinye kuphela. Ingxaki yee-cylinders ezisebenzayo ngesinye kukungangqinelani kwamandla okukhupha nge-full stroke ngenxa yamandla e-spring achaseneyo. Umfanekiso 4 ubonisa i-actuator ejikelezayo ye-pneumatic esebenza ngesinye esebenza ngesibini.
Kwi-actuator esebenza kabini, umoya unikezelwa kwiigumbi ezikumacala omabini e-piston (ii). Uxinzelelo lomoya oluphezulu kwelinye icala lunokuqhuba i-piston (ii) kwelinye icala. Ii-actuator ezisebenzayo kabini zisetyenziswa xa umsebenzi kufuneka wenziwe kumacala omabini. Umfanekiso 5 ubonisa i-actuator ejikelezayo esebenza kabini ene-pneumatic.
Enye yeenzuzo zeesilinda ezisebenza kabini kukuba amandla okukhupha ahlala ehleli kuluhlu olupheleleyo lokujikeleza. Iingxaki zeesilinda ezisebenza kabini kukufuna umoya ocinezelweyo ukuze zihambe kuzo zombini iindlela kunye nokungabikho kwendawo echaziweyo xa amandla okanye uxinzelelo lungaphumeleli.
Ukubeka iindawo ezininzi
Ezinye ii-actuator ze-rack-and-pinion ziyakwazi ukuma kwiindawo ezahlukeneyo kuluhlu lokujikeleza ngokulawula uxinzelelo kwiizibuko. Iindawo zokuma zingaba kuzo naziphi na iindlela, okwenza kube nokwenzeka ukuba i-actuator idlule ngokukhetha indawo yokuma ephakathi.
Iibholiti zokumisa uhambo
Iibholiti zokumisa ukuhamba zikwicala lomzimba we-actuator (njengoko kubonwe kuMfanekiso 6) kwaye zivumela ukulungiswa kweendawo zokuphela kweepiston ngokunciphisa ukujikeleza kwegiya ye-pinion ukusuka ngaphakathi. Xa ufaka i-actuator, qhuba zombini iibholiti zokumisa ukuhamba de ziqhagamshelane nesivalo sokumisa ukuhamba. Qhubeka ukrufula ibholiti yokumisa ukuhamba ekhohlo de isithuba se-pinion esibonakalayo phezulu sijikeleze kwindawo ehambelana nobude bomzimba we-actuator.
Isicelo seMveliso: i-actuator yombane ejika inxalenye
Ngenxa yokukhupha kwabo i-torque rhoqo,Ii-actuators ze-rack kunye ne-pinionZisetyenziswa rhoqo kwaye zihlala ziyindlela ekhethwayo yee-actuators zomoya kwiivalvu. Zisetyenziselwa ukuxuba, ukulahla inkunkuma, ukondla okungenaxesha, ukujikeleza okuqhubekayo, ukujika, ukubeka indawo, ukushukuma, ukuphakamisa, ukuvula nokuvala kunye nokujika. Ezi actuators zisetyenziselwa imisebenzi eyahlukeneyo yoomatshini kwishishini lentsimbi, ukuphathwa kwezinto, imisebenzi yaselwandle, izixhobo zokwakha, oomatshini bemigodi, kunye nolawulo lwamandla e-hydraulic.
