I-actuator ye-Rack ne-Pinion
Kuyini i-Rack and Pinion actuator?
Ama-actuator omoya e-rack-and-pinion, ebizwa nangokuthi amasilinda okujikeleza alinganiselwe, angama-actuator ajikelezayo asetshenziselwa ukujika, ukuvula, ukuvala, ukuxuba, ukujikisa, ukubeka, ukuqondisa kanye neminye imisebenzi eminingi yemishini ehilela ukujikeleza okulinganiselwe. Lawa ma-actuator avame ukusetshenziselwa ukwenza ngokuzenzakalela ama-valve okujika kwekota, njengama-valve ebhola noma ama-butterfly.
Ama-actuator e-rack-and-pinion e-pneumaticguqula amandla omoya ocindezelwe nge-cylinder yomoya abe ukunyakaza okujikelezayo okuguquguqukayo. Igesi ehlanzekile, eyomile, necutshunguliwe edingekayo yi-actuator inikezwa ngesiteshi somoya esiphakathi esicindezelwe, esivame ukusekela uhla lwamadivayisi omoya ohlelweni lwenqubo.
Izici eziyinhloko ze-Rack and Pinion actuator
Uma kuqhathaniswa nezingxenye zabo zekhawuntara kagesi,Ama-actuator e-rack kanye ne-pinion ngokuvamile zihlala isikhathi eside, zifaneleka kangcono ezindaweni eziyingozi futhi azibizi kakhulu. Ngaphezu kwalokho, zivame ukudinga ukulungiswa okuncane futhi zinikeza i-torque ephezulu uma kuqhathaniswa nosayizi wazo.
Ukucaciswa kobuchwepheshe be-actuator ye-Rack ne-Pinion
Umklamo we-rack eyodwa vs. i-rack ekabili
Ama-actuator e-rack-and-pinion anikeza ububanzi obukhulu be-torque kanye nokujikeleza uma kuqhathaniswa nezinye izindlela zokuguqula ukuguqula amandla aqondile abe yi-torque ejikelezayo. Asebenza kahle kakhulu ngomshini futhi ama-torque akwazi ukuwakhiqiza asukela ku-Nm ezimbalwa kuya ezinkulungwaneni eziningi ze-Nm.
Kodwa-ke, enye inkinga engaba khona yomklamo we-rack-and-pinion i-backlash. I-backlash yenzeka lapho amagiya e-rack ne-pinion engaqondani ngokuphelele futhi kukhona igebe elincane phakathi kokuxhumeka ngakunye kwe-gear. Lokhu kungahambisani kahle kungabangela ukuguguleka kwamagiya ngesikhathi somjikelezo wokuphila we-actuator, okubuye kwandise i-backlash.
Iyunithi ye-rack ephindwe kabili isebenzisa ama-rack amabili ezinhlangothini eziphambene ze-pinion. Lokhu kusiza ekuqedeni ukushayisana ngenxa yamandla okuphikisana futhi kuphinda kabili i-torque yokukhipha yeyunithi futhi kwandisa ukusebenza kahle komshini kwesistimu. Ku-actuator esebenza kabili eboniswe kuMfanekiso 3, amakamelo amabili ezinhlangothini agcwele umoya ocindezelwe, osunduza ama-piston phakathi nendawo bese kubuyisela ama-piston endaweni yawo yokuqala, igumbi eliphakathi nendawo nalo liyacindezelwa.
Umsebenzi
Ama-actuator omoya e-rack-and-pinion angaba yi-single-acting noma i-double-acting. Kungenzeka futhi ukuthi la ma-actuator anikeze izitobhi eziningi.
Ukulingisa komuntu oyedwa vs. ukulingisa okubili
Ku-actuator esebenza kanye, umoya unikezwa ohlangothini olulodwa lwe-piston futhi unesibopho sokunyakaza kwe-piston ohlangothini olulodwa kuphela. Ukunyakaza kwe-piston ohlangothini oluphambene kwenziwa yisipilingi somshini. Ama-actuator asebenza kanye kuphela agcina umoya ocindezelwe, kodwa enza umsebenzi ohlangothini olulodwa kuphela. Inkinga yama-cylinder asebenza kanye kuphela amandla okukhipha angaguquki ngokushaya okugcwele ngenxa yamandla esipilingi aphikisanayo. Isithombe 4 sibonisa i-actuator ejikelezayo ye-pneumatic esebenza kanye kuphela.
Ku-actuator esebenza kabili, umoya unikezwa emakamelweni ezinhlangothini zombili ze-piston. Umfutho womoya ophezulu ohlangothini olulodwa ungashayela i-piston (ama-piston) kolunye uhlangothi. Ama-actuator asebenza kabili asetshenziswa lapho umsebenzi udinga ukwenziwa kuzo zombili izinhlangothi. Isithombe 5 sibonisa i-actuator ejikelezayo ye-pneumatic esebenza kabili.
Enye yezinzuzo zamasilinda asebenza kabili amandla okukhipha aqhubekayo ngokusebenzisa uhla oluphelele lokujikeleza. Izithiyo zamasilinda asebenza kabili isidingo sawo somoya ocindezelwe ukuze ahambe kuzo zombili izinhlangothi kanye nokuntuleka kwendawo echaziwe uma kwenzeka ukwehluleka kwamandla noma ingcindezi.
Ukubeka izindawo eziningi
Amanye ama-actuator e-rack-and-pinion ayakwazi ukuma ezindaweni eziningi ngokusebenzisa ububanzi bokujikeleza ngokulawula ingcindezi emachwebeni. Izikhundla zokuma zingaba kunoma yiluphi uchungechunge, okwenza kube nokwenzeka ukuthi i-actuator idlule ngokukhetha isikhundla sokuma esiphakathi nendawo.
Amabhawodi okuma okuhamba
Amabhawodi okumisa ukuhamba asohlangothini lomzimba we-actuator (njengoba kuboniswe kuMfanekiso 6) futhi avumela ukulungiswa kwezindawo zokugcina zama-piston ngokunciphisa ukujikeleza kwegiya le-pinion kusuka ngaphakathi. Uma ufaka i-actuator, shayela womabili amabhawodi okumisa ukuhamba aze athinte isivalo sokumisa ukuhamba. Qhubeka ugoqa ibholodi lokumisa ukuhamba kwesobunxele kuze kube yilapho isikhala se-pinion esibonakalayo phezulu sijikeleza endaweni ehambisana nobude bomzimba we-actuator.
Isicelo Somkhiqizo: i-actuator kagesi ephenduka ingxenye
Ngenxa yokukhishwa kwawo kwe-torque okungaguquki,Ama-actuator e-rack kanye ne-pinionZivame ukusetshenziswa futhi ngokuvamile ziyisitayela esithandwayo sama-actuator omoya kuma-valve. Zisetshenziselwa ukuxuba, ukulahla, ukuphakela ngezikhathi ezithile, ukujikeleza okuqhubekayo, ukujika, ukubeka, ukunyakazisa, ukuphakamisa, ukuvula nokuvala nokujika. Lawa ma-actuator asetshenziselwa imisebenzi eyahlukahlukene yemishini embonini yensimbi, ukuphathwa kwezinto, imisebenzi yasolwandle, imishini yokwakha, imishini yezimayini, kanye nokuqondisa amandla kagesi.
