Chifukwa chiyani encoder iyenera kuyikidwa pa injini?Kodi encoder imagwira ntchito bwanji?

Panthawi yogwiritsira ntchito injini, nthawi yeniyenikuyang'aniraza magawo monga apano, liwiro, ndi malo achibale a shaft yozungulira mozungulira, kudziwa momwe thupi lagalimoto lilili ndi zida zoyendetsedwa, komanso kuwongolera momwe galimoto ikuyendera ndi zida munthawi yeniyeni, kuti muzindikire servo, kuwongolera liwiro, ndi zina zambiri.Apa, pogwiritsa ntchito encodermonga choyezera chakutsogolo sichimangofewetsa kachitidwe ka kuyeza, komanso kolondola, kodalirika komanso kwamphamvu.

Encoder ndi sensa yozungulira yomwe imasintha malo ndi kusamuka kwa magawo ozungulira kukhala mndandanda wa ma siginecha a digito.Zizindikiro za pulse izi zimasonkhanitsidwa ndikusinthidwa ndi dongosolo lolamulira, ndipo mndandanda wa malangizo amaperekedwa kuti asinthe ndikusintha kayendetsedwe ka zipangizo.Ngati encoder ikuphatikizidwa ndi rack giya kapena screw screw, itha kugwiritsidwanso ntchito kuyeza malo ndi kusamuka kwa mizere yosuntha.

Ma encoder amagwiritsidwa ntchito pamakina oyankha ma siginolo amoto, muyeso ndi zida zowongolera.Encoder imapangidwa ndi magawo awiri: optical code disc ndi wolandila.Mawonekedwe osinthika owoneka bwino opangidwa ndi kuzungulira kwa disc ya optical code amasinthidwa kukhala magawo amagetsi ofananira, ndipo ma sign omwe amayendetsa zida zamagetsi amatuluka kudzera mu preamplifier ndi ma sign processing system mu inverter..

Nthawi zambiri, encoder yozungulira imatha kungobweza chizindikiro chothamanga, chomwe chimafananizidwa ndi mtengo wokhazikitsidwa ndikubwezeredwa kugawo loyendetsa inverter kuti lisinthe liwiro la mota.

Malinga ndi mfundo yodziwira, encoder imatha kugawidwa kukhala optical, maginito, inductive ndi capacitive.Malinga ndi kukula kwake ndi mawonekedwe otulutsa ma siginecha, imatha kugawidwa m'magulu atatu: owonjezera, mtheradi ndi wosakanizidwa.

Encoder yowonjezereka, malo ake amatsimikiziridwa ndi kuchuluka kwa ma pulse owerengedwa kuchokera pa zero;amasintha kusamuka kukhala chizindikiro chamagetsi chanthawi ndi nthawi, ndiyeno kutembenuza chizindikiro chamagetsi kukhala chowerengera, ndipo kuchuluka kwa ma pulses kumayimira kusamuka;mtheradi Malo amtundu wa encoder amatsimikiziridwa ndi kuwerenga kwa code yotulutsa.Kuwerenga kwa code ya malo aliwonse mkati mwa bwalo ndi apadera, ndipo makalata amodzi ndi amodzi omwe ali ndi malo enieniwo sangawonongeke pamene mphamvu ikutha.Chifukwa chake, encoder yowonjezereka ikazimitsidwa ndikuyatsidwanso, kuwerenga kwamalo kumakhala kwapano;malo aliwonse a encoder mtheradi amafanana ndi kachidindo kena ka digito, kotero kuti mtengo wake wosonyezedwa umangogwirizana ndi malo oyambira ndi omalizira a muyeso, pamene Iwo alibe chochita ndi ndondomeko yapakatikati ya kuyeza.

Encoder, monga gawo lotolera zidziwitso zamagalimoto akuthamanga, imalumikizidwa ndi mota kudzera pakuyika kwamakina.Nthawi zambiri, maziko a encoder ndi shaft terminal amafunika kuwonjezeredwa ku injini.Pofuna kuwonetsetsa kuti magwiridwe antchito agalimoto ndi otetezeka komanso ogwiritsira ntchito makina ogulira, coaxiality kufunikira kwa shaft yolumikizira encoder ndi shaft yayikulu ndiye chinsinsi pakupanga.
