Actuator ya Rack na Pinion
Actuator ya Rack na Pinion ni iki?
Ibikoresho by'umwuka bya Rack-and-pinion, kandi zitwa silindiri zizunguruka nke, ni actuators zizunguruka zikoreshwa mu guhindukira, gufungura, gufunga, kuvanga, guhindagurika, gushyira mu mwanya, kuyobora n'indi mirimo myinshi ya mekanike irimo kuzunguruka ku buryo buciriritse. Izi actuators zikunze gukoreshwa mu kwikora kwa vali zo guhindukira kimwe cya kane, nka vali z'umupira cyangwa z'ibinyugunyugu.
Ibikoresho by'amashanyarazi bya pneumatic rack-and-pinionguhindura ingufu z'umwuka ufunze ukoresheje silinda y'umwuka ikajya mu ngendo izunguruka. Gazi isukuye, yumye kandi itunganyijwe isabwa n'iyi actuator itangwa binyuze muri sitasiyo y'umwuka ifunze, isanzwe ishyigikira ibikoresho bitandukanye by'umwuka muri sisitemu y'imikorere.
Ibintu by'ingenzi bigize Rack na Pinion actuator
Ugereranije n'ibice byabyo by'amashanyarazi,Ibikoresho byo gukamura ibyuma n'ibyuma bikoresha ibyuma muri rusange biraramba cyane, bibereye ahantu hashobora guteza akaga kandi bihendutse. Byongeye kandi, akenshi bisaba gusanwa gake kandi bitanga imbaraga nyinshi ugereranije n'ingano yabyo.
Ibisobanuro bya tekiniki bya Rack na Pinion actuator
Igishushanyo mbonera cy'agasanduku kamwe ugereranije n'igisanduku kibiri
Imashini zikora amashanyarazi zitanga uburebure bwa torque n'izunguruka ugereranije n'izindi nzira zo guhindura imbaraga zikoreshwa mu guhindura torque zikora torque. Zifite ubushobozi bwo gukora neza cyane kandi torque zishobora gukora zigera kuri Nm ebyiri kugeza ku bihumbi byinshi bya Nm.
Ariko, kimwe mu bibazo bishobora kubaho mu miterere ya rack-and-pinion ni backlash. Backlash ibaho iyo rack na pinion gears zidahuye neza kandi hari icyuho gito hagati ya buri connection. Uku kutumvikana neza gushobora gutuma ibyuma byangirika mu gihe cy'ubuzima bwa actuator, ibyo bigatuma backlash yongera.
Igice cy’urukiramende rw’ingufu ebyiri gikoresha uduce duto two ku mpande z’uruhande rw’inyuma. Ibi bifasha gukuraho gushyuha bitewe n’imbaraga zo guhangana, kandi bikongera imbaraga zo gusohora k’igice, kandi byongera ubushobozi bwa mekanike. Muri actuator ikora ku mpande ebyiri igaragara ku Ishusho ya 3, ibyumba bibiri ku mpande byuzuyemo umwuka urimo umuvuduko, utuma piston zijya hagati, hanyuma kugira ngo piston zigarure aho zari ziri, icyumba kiri hagati na cyo gishyirwamo umuvuduko.
Imikorere
Ibikoresho by'umwuka bya Rack-and-pinion bishobora kuba bikora rimwe cyangwa bibiri. Birashoboka kandi ko ibi bikoresho bishobora gutanga uburyo bwinshi bwo guhagarika.
Gukina ari umwe cyangwa gukina kabiri
Mu cyuma gikoresha umwuka umwe gusa, umwuka utangwa ku ruhande rumwe rwa piston kandi ni wo utuma piston igenda mu cyerekezo kimwe gusa. Ingendo za piston mu cyerekezo gitandukanye zikorwa n'isoko ya mekanike. Ibikoresho bikoresha umwuka umwe bibungabunga umwuka ufunze, ariko bikora akazi mu cyerekezo kimwe gusa. Imbogamizi za silindiri zikoresha umwuka umwe ni imbaraga zidahindagurika zisohoka binyuze mu gukanda burundu bitewe n'imbaraga z'isoko zihanganye. Ishusho ya 4 igaragaza actuator ikora umwuka umwe ifite ibyuma bibiri.
Muri actuator ikora inshuro ebyiri, umwuka ugezwa mu byumba byo ku mpande zombi za piston (amapine). Umuvuduko mwinshi w'umwuka ku ruhande rumwe ushobora gutuma piston (amapine) ijya ku rundi ruhande. Actuator ikora inshuro ebyiri ikoreshwa iyo akazi gakeneye gukorwa mu byerekezo byombi. Ishusho ya 5 igaragaza actuator ikora inshuro ebyiri ikora inshuro ebyiri.
Imwe mu nyungu za silindiri zikora inshuro ebyiri ni imbaraga zihoraho zisohoka mu buryo buzenguruka neza. Ingaruka mbi za silindiri zikora inshuro ebyiri ni uko zikenera umwuka ufunze kugira ngo zigende mu byerekezo byombi ndetse no kutagira aho zihurira mu gihe habayeho ikibazo cy'ingufu cyangwa umuvuduko.
Gushyira ahantu henshi
Actuators zimwe na zimwe zishobora guhagarara ahantu henshi mu gihe cy'izenguruka binyuze mu kugenzura umuvuduko ku byambu. Aho guhagarara hashobora kuba mu buryo ubwo aribwo bwose, bigatuma actuator ishobora guhitamo aho ihagarara hagati y'uburyo bubiri.
Ibikoresho byo guhagarara mu ngendo
Udukingirizo two guhagarara turi ku ruhande rw'umubiri w'umukoresha (nk'uko bigaragara ku Ishusho ya 6) kandi twemerera guhindura aho pisitoni zihagarara binyuze mu kugabanya kuzenguruka kw'icyuma gifata pinion uhereye imbere. Mu gihe ushyiramo umukoresha, shyiramo utwo dukingirizo twombi two guhagarara kugeza igihe duhuye n'umupfundikizo wo guhagarara. Komeza uzungurutse agakingirizo ko guhagarara k'ibumoso kugeza igihe agakingirizo kagaragara hejuru kazungurutse kagana ku mwanya uhwanye n'uburebure bw'umubiri w'umukoresha.
Ikoreshwa ry'ibicuruzwa: icyuma gikoresha amashanyarazi gikoresha igice
Bitewe n'uko torque yabo idahinduka,Ibikoresho byo gukamura ibyuma n'ibyuma bikoresha ibyumazikoreshwa kenshi kandi akenshi ni zo zikundwa cyane mu buryo bwa actuators za pneumatic kuri valves. Zikoreshwa mu kuvanga, gusukamo imyanda, gutanga amafunguro buri gihe, kuzunguruka buri gihe, guhinduranya, gushyira mu mwanya, guterura, gufungura no gufunga no guhinduranya. Izi actuators zikoreshwa mu mirimo itandukanye ya mekanike mu nganda z'ibyuma, gucunga ibikoresho, ibikorwa byo mu mazi, ibikoresho by'ubwubatsi, imashini zicukura amabuye y'agaciro, no kuyobora ingufu za hydraulic.
