Rack ndi Pinion actuator
Kodi Rack ndi Pinion actuator ndi chiyani?
Ma rack-and-pinion pneumatic actuators, omwe amatchedwanso masilinda ozungulira ochepa, ndi makina ozungulira omwe amagwiritsidwa ntchito potembenuza, kutsegula, kutseka, kusakaniza, kugwedeza, kuika, kuwongolera ndi zina zambiri zamakina zomwe zimakhudza kuzungulira koletsedwa.Ma actuators awa amagwiritsidwanso ntchito popanga ma valve ozungulira kotala, monga ma valve a mpira kapena agulugufe.
Pneumatic rack-and-pinion actuatorssinthani mphamvu ya mpweya woponderezedwa pogwiritsa ntchito silinda ya mpweya kukhala yoyenda mozungulira.Gasi waukhondo, wowuma, komanso wokonzedwanso wofunidwa ndi woyendetsa uyu amaperekedwa kudzera pa malo opangira mpweya wapakati, omwe nthawi zambiri amathandizira zida zingapo zamapneumatic pamakina opangira.
Zofunikira zazikulu za Rack ndi Pinion actuator
Poyerekeza ndi zida zawo zamagetsi zamagetsi,Rack ndi pinion actuators nthawi zambiri amakhala olimba, oyenerera malo owopsa komanso otsika mtengo.Kuphatikiza apo, nthawi zambiri amafunikira kusamalidwa pang'ono ndipo amapereka torque yapamwamba poyerekeza ndi kukula kwawo.
Mafotokozedwe aukadaulo a Rack ndi Pinion actuator
Choyika chimodzi motsutsana ndi mapangidwe a rack awiri
Ma rack-and-pinion actuators amapereka mitundu yayikulu kwambiri ya torque ndi kuzungulira poyerekeza ndi njira zina zosinthira mphamvu ya mzere kukhala torque yozungulira.Ili ndi mphamvu zamakina apamwamba komanso ma torque omwe amatha kupanga kuyambira ma Nm angapo mpaka masauzande ambiri a Nm.
Komabe, cholepheretsa chimodzi chomwe chingatheke pamapangidwe a rack-and-pinion ndikubwerera.Kubwereranso kumachitika pamene ma rack ndi ma pinion magiya sali ogwirizana kwathunthu ndipo pali kusiyana kochepa pakati pa kulumikizana kulikonse.Kusokoneza uku kungayambitse kuvala kwa magiya panthawi yamoyo wa actuator, zomwe zimawonjezera kubweza.
Chipinda chokhala ndi rack iwiri chimagwiritsa ntchito zoyikapo mbali ziwiri za pinion.Izi zimathandiza kuthetsa kubweza chifukwa cha mphamvu yotsutsa komanso kuwirikiza kawiri ma torque a unit ndikuwonjezera mphamvu zamakina zamakina.Mu actuator yochita kawiri yomwe ikuwonetsedwa mu Chithunzi 3, zipinda ziwiri zomwe zili m'mbali mwake zimadzazidwa ndi mpweya woponderezedwa, womwe umakankhira ma pistoni pakatikati ndikubwezeretsa ma pistoni pamalo oyamba, chipinda chomwe chili pakatikati chimakhala chopanikizika.
Ntchito
Ma rack-and-pinion pneumatic actuators amatha kukhala amodzi kapena awiri.Ndizothekanso kuti ma actuators awa apereke maimidwe angapo.
Sewero limodzi vs. Kuchita kawiri
Mu actuator imodzi yokha, mpweya umangoperekedwa kumbali imodzi ya pistoni ndipo umayang'anira kayendetsedwe ka pistoni kumbali imodzi yokha.Kusuntha kwa pisitoni kumbali ina kumachitidwa ndi kasupe wamakina.Ma actuator omwe amagwira ntchito imodzi amasunga mpweya woponderezedwa, koma amagwira ntchito mbali imodzi yokha.Chotsalira cha masilinda ochita kamodzi ndi mphamvu yotulutsa yosagwirizana ndi sitiroko yonse chifukwa cha mphamvu yotsutsana ndi masika.Chithunzi 4 chikuwonetsa chowongolera chozungulira chokhala ndi choyikapo chimodzi chokhala ndi rack pneumatic rotary actuator.
Mu actuator yochita kawiri, mpweya umaperekedwa kuzipinda za mbali zonse za pistoni.Kuthamanga kwakukulu kwa mpweya kumbali imodzi kungathe kuyendetsa piston (ma) mbali ina.Ma actuator ochita kawiri amagwiritsidwa ntchito pamene ntchito ikufunika kuchitidwa mbali zonse ziwiri.Chithunzi 5 chikuwonetsa chowotcha chopindika chapawiri-rack pneumatic.
Chimodzi mwazabwino zamasilinda ochita kawiri ndi mphamvu yotulutsa mosalekeza kudzera mumitundu yonse yozungulira.Zovuta za masilinda ochita kawiri ndi kufunikira kwawo kwa mpweya woponderezedwa kuti usunthe mbali zonse ziwiri komanso kusowa kwa malo odziwika ngati mphamvu kapena kulephera kulephera.
Malo angapo
Ena opanga ma rack-and-pinion actuators amatha kuyima pamalo angapo kudzera mumayendedwe ozungulira powongolera kukakamiza pamadoko.Maimidwe amatha kukhala motsatana kulikonse, kupangitsa kuti chowongoleracho chizitha kusankha choyimitsa chapakati.
Maboti oyimitsa maulendo
Maboti oyimitsa maulendo ali kumbali ya thupi la actuator (monga momwe tawonera pa Chithunzi 6) ndikulola kusintha kwa malo omalizira a pistoni pochepetsa kuzungulira kwa pinion gear kuchokera mkati.Mukayika choyatsira, yendetsani mabawuti onse oyenda mpaka atalumikizana ndi kapu yoyimitsa maulendo.Pitirizani kupotoza bawuti yoyimitsa yoyendera kumanzere mpaka kagawo ka pinion kowonekera pamwamba kazungulira kofanana ndi kutalika kwa thupi la actuator.
Kugwiritsa Ntchito: gawo lotembenuza magetsi
Chifukwa cha kutulutsa kwawo kosalekeza kwa torque,Rack ndi pinion actuatorsamagwiritsidwa ntchito pafupipafupi komanso kalembedwe kamene kamakonda ka pneumatic actuators kwa mavavu.Amagwiritsidwa ntchito kusakaniza, kutaya, kudyetsa kwapakatikati, kusinthasintha kosalekeza, kutembenuza, kuika, kugwedeza, kukweza, kutsegula ndi kutseka ndi kutembenuka.Ma actuatorswa amagwiritsidwa ntchito pamakina osiyanasiyana m'makampani azitsulo, kunyamula zinthu, ntchito zam'madzi, zida zomangira, makina amigodi, ndi chiwongolero champhamvu cha hydraulic.
