Kungani kufanele kufakwe isishumeki kumotho? Sisebenza kanjani isifaki khodi?

Ngesikhathi sokusebenza kwenjini, isikhathi sangempelaukuqaphazamapharamitha anjengamanje, isivinini, kanye nokuma okuhlobene kwe-shaft ejikelezayo endaweni eyindilinga, ukunquma isimo somzimba wemoto kanye nezinto ezisetshenziswayo, kanye nokulawula ngokuqhubekayo isimo sokusebenza semoto nemishini ngesikhathi sangempela, ukuze uthole i-servo, ukulawulwa kwesivinini, njll. Imisebenzi eminingi ethile.Lapha, usebenzisa isifaki khodinjengoba isici sokulinganisa esingaphambili singagcini nje ngokulula kakhulu uhlelo lokulinganisa, kodwa futhi sinembile, sithembekile futhi sinamandla.

I-encoder iyinzwa ejikelezayo eguqula indawo kanye nokugudluzwa kwezingxenye ezijikelezayo zibe uchungechunge lwamasignali we-digital pulse. Lezi zibonakaliso ze-pulse ziqoqwa futhi zicutshungulwe uhlelo lokulawula, futhi uchungechunge lweziyalezo lukhishwa ukulungisa nokuguqula isimo sokusebenza semishini.Uma isishumeki sihlanganiswe ne-gear rack noma isikulufu, singasetshenziswa futhi ukukala indawo kanye nokugudluzwa kwezingxenye ezihambayo.

Izifaki khodi zisetshenziswa ezinhlelweni zempendulo yesignali yokuphuma kwezimoto, ukulinganisa kanye nemishini yokulawula. Isishumeki sakhiwe izingxenye ezimbili: i-optical code disc kanye nomamukeli. Imingcele ye-optical variable ekhiqizwa ukujikeleza kwe-optical code disc iguqulwa ibe imingcele kagesi ehambisanayo, futhi amasignali ashayela amadivayisi kagesi aphuma nge-preamplifier kanye nesistimu yokucubungula isignali ku-inverter. .

Ngokuvamile, isishumeki esijikelezayo singakwazi ukubuyisela isignali yesivinini kuphela, eqhathaniswa nenani elimisiwe futhi ibuyiselwe kuyunithi yokukhipha inverter ukulungisa isivinini semoto.

Ngokomgomo wokutholwa, isishumeki singahlukaniswa sibe yi-optical, magnetic, inductive kanye ne-capacitive. Ngokwendlela yayo yesikali kanye nefomu lokukhipha isignali, ingahlukaniswa ngezinhlobo ezintathu: okukhulayo, okuphelele kanye ne-hybrid.

Isifaki khodi esikhuphukayo, indawo yaso inqunywa ngenani lama-pulses abalwe ukusuka kumaki aziro; iguqula ukugudluzwa kube isignali kagesi yezikhathi ezithile, bese iguqula isignali kagesi ibe ishayela lokubala, futhi inani lama-pulses limele ukususwa; ngokuphelele Indawo yohlobo lokufaka ikhodi inqunywa ukufundwa kwekhodi yokuphumayo. Ukufundwa kwekhodi yokuphuma kwendawo ngayinye ngaphakathi kwendingiliza kuhlukile, futhi ukuxhumana okukodwa kuya koyedwa okunendawo yangempela ngeke kulahleke lapho amandla enqanyulwa.Ngakho-ke, lapho isishumeki esikhuphukayo sivaliwe futhi sivulwa futhi, ukufundwa kwendawo okwamanje; indawo ngayinye yesishumeki sekhodi esiphelele sihambisana nekhodi ethile yedijithali, ngakho-ke inani layo elibonisiwe lihlobene kuphela nendawo yokuqala nesiphetho yesilinganiso, kuyilapho Ayihlangene nenqubo emaphakathi yokulinganisa.

Isishumeki, njengengxenye yokuqoqwa kolwazi yesimo sokusebenza kwemoto, sixhunywe kumotho ngokufaka imishini. Ezimweni eziningi, isisekelo se-encoder kanye ne-terminal shaft kudingeka kwengezwe enjini.Ukuze kuqinisekiswe ukusebenza kahle nokuphepha kokusebenza kwemoto kanye nokusebenza kwesistimu yokutholwa, imfuneko ye-coaxiality ye-encoder end connection shaft kanye ne-shaft eyinhloko iyisihluthulelo senqubo yokukhiqiza.
