Iningi lama-slip rings asebenzisa ukuxhumana okungqubuzanayo njengendlela yokuxhuma kagesi. Kuphephile, kuthembekile, futhi kungahlangabezana nenani leziteshi ezidingekayo kumakhasimende. Ama-slip rings asemakethe njengamanje avame ukusebenzisa leli fomu lokuxhumana. Ezinye zifaka phakathi ukuxhumana kwe-mercury, ukudluliselwa kwe-infrared, ukudluliselwa okungenantambo, njll., okungeyona imikhiqizo evamile okwamanje, ngoba ama-disc slip rings akhiqizwa ngale ndlela asenemikhawulo eminingi, njengenkinga yokuvuza kokuxhumana kwe-mercury, futhi kunzima ukukhiqiza iziteshi ezingaphezu kwezingu-8, futhi izindleko zokukhiqiza ziphezulu kakhulu. Izindlela zokudlulisela nge-infrared kanye nokudluliselwa okungenantambo zinezinkinga zokuphazamiseka kwesignali, futhi iziteshi zamandla ezinamandla aphezulu azikwazi ukudluliselwa ngale ndlela.
Izinhlangano zendandatho yokushelela zingahlukaniswa zibe yizindandatho zokushelela ezisheshayo, izindandatho zokushelela ezisheshayo, kanye namahinji ajikelezayo asheshayo ngokuya ngemvamisa yesiginali yokudlulisa. Izindandatho zokushelela zivame ukubhekisela ezinhlotsheni ezimbili zokuqala kuphela. Izinkomba zokusebenza kukagesi zezinhlangano zendandatho yokushelela yilezi: ukumelana nokushisa, ukumelana nokuxhumana, amandla e-dielectric kanye nokukhuluma nge-crosstalk. Kumasongo okushelela asheshayo, ngoba imvamisa iphakeme, ukuvikela, ukuhambisana kwe-impedance, i-voltage yomsindo, njll. kumele kucatshangelwe. Ngokuphathelene nomklamo wesakhiwo, ukuxhumana okuthembekile kumele kuqinisekiswe kuqala ukuqinisekisa ukuthi yonke imigqa ixhunywe njalo. Ngakho-ke, ukuhanjiswa kukagesi kwezinto ezisetshenziselwa ibhulashi kuyadingeka ukuze kube kuhle, ingcindezi endandatho yokushelela kufanele ifaneleke, ukungafani nokuthuthumela kwendandatho yokushelela kufanele kube kuncane, ukumelana nokuguguleka kufanele kube kuhle, i-torque yokungqubuzana kufanele ibe yincane, futhi kufanele kube lula ukuyinakekela.
1) Indandatho yokushelela ephansi: inhlanganisela yendandatho yokushelela esebenzisa ukuthintana okushelelayo ukudlulisa izimpawu namandla anemvamisa ephansi. Amasongo avamile okushelela yizindandatho zokushelela ezisilinda kanye nezindandatho zokushelela ezihlukile. Amasongo okuqhuba amasongo okushelela ayisilinda ahlukaniswe ngamasongo ayisicaba kanye nezindandatho ezimise okwe-V. Izinto zokwakha izindandatho zokushelela ngokuvamile ziyithusi, ithusi, isiliva lemali kanye negolide. Amabhulashi yi-palladium, i-alloy yegolide noma amabhulashi ensimbi ahlanganiswe ngegolide kanye namabhulashi ahlanganisiwe ethusi-graphite. Uma inani lezindandatho zokushelela likhulu, indandatho yokushelela eyisilinda iqukethe amasethi amabili amabhulashi aphezulu naphansi kanye ne-adaptha ehlukile, kodwa usayizi wayo we-axial mkhulu. Ukusetshenziswa kwezindandatho zokushelela ezihlukile kunganciphisa kakhulu usayizi we-axial, ivolumu kanye nesisindo. Indandatho yokushelela ehlukene iqukethe amasethi amabili amabhulashi aphezulu naphansi kanye ne-adaptha ehlukile. Ibhulashi eliphezulu lijikeleza nge-azimuth ye-antenna, kuyilapho ibhulashi eliphansi liqinile. Kunezingcezu ezimbili zokuthintana ezingenhla naphansi epuletini le-adaptha ehlukile. Izingcezu zokuthintana ezihambisanayo zixhunywe ngezintambo, futhi indlela yokuhlukanisa isetshenziselwa ukwenza isivinini sayo sokujikeleza sibe yi-1/2 yesivinini sokujikeleza se-azimuth. Uma i-antenna ijikeleza, ugesi ogeleza ebhulashini ngalinye elingezansi udlula kumasekethe okuxhumana okukodwa noma amabili ku-turntable ehlukile bese ugeleza usuka ebhulashini eliphezulu elihambisanayo ukuqinisekisa ukuthi isekethe ephakathi kwengxenye egxilile nengxenye ejikelezayo ihlala ixhunyiwe. Impuphu egqokwe yindandatho yokuxhumana eshelelayo ingabangela isekethe esifushane phakathi kwamasongo. Ngakho-ke, isakhiwo kufanele siqinisekise ukuthi kulula ukusihlanza, futhi isakhiwo esihlanganisiwe sivame ukusetshenziselwa ukwenza lula ukulungiswa noma ukushintshwa kwezingxenye endaweni.
2) Indandatho yokushelela yemvamisa ephakathi: i-slip ring assembly esetshenziselwa ukudlulisa izimpawu namandla emvamisa ephakathi ye-radar (amashumi e-megahertz). Le ndandatho yokushelela inomvamisa ophezulu futhi idinga ukuvikelwa. Izindandatho zokushelela ezijwayelekile zesivinini esiphezulu zingasetshenziswa futhi ukudlulisa izimpawu ezingaphansi kwe-12MHz. Indandatho eyodwa ixhunywe kumqhubi ophakathi, kanti enye indandatho ixhunywe kungqimba lwangaphandle lwekhebula njengendandatho yokuvikela. Izindandatho zokushelela ezivikelwe yi-coaxial zivame ukusetshenziselwa ukudlulisa izimpawu ezingaphezu kwe-12MHz. Ingxenye enqamula yale ndandatho yokushelela inomumo we-groove, okuyi-coaxial coaxial conductor engunxande. Kukhona nendandatho yokushelela yemvamisa ephakathi ene-capacitive, umqhubi ophakathi une-annular, usekelwa yi-insulating pad kungqimba lokuvikela, kukhona igebe phakathi kwengxenye ejikelezayo nengxenye ezinzile, futhi azithintani, futhi isignali yemvamisa ephakathi ihlanganiswa nge-capacitance. Endabeni yobubanzi bokujikeleza kwe-antenna obulinganiselwe, idivayisi yokugoqa ikhebula ingasetshenziswa esikhundleni sendandatho yokushelela.
