Kugawa kwa momwe mphete zoyendetsera zoyendetsa zimagwiritsidwira ntchito m'zitseko zozungulira zokha zokhala ndi mapiko awiri

Ma slip ring ambiri odutsa m'mabowo amagwiritsa ntchito friction contact ngati njira yolumikizira magetsi. Ndi otetezeka, odalirika, ndipo amatha kukwaniritsa kuchuluka kwa njira zomwe makasitomala amafunikira. Ma slip ring omwe ali pamsika nthawi zambiri amagwiritsa ntchito fomu yolumikizira iyi. Zina zimaphatikizapo mercury contact, infrared transmission, wireless transmission, ndi zina zotero, zomwe sizili zinthu zodziwika bwino pakadali pano, chifukwa ma disc slip rings opangidwa mwanjira imeneyi akadali ndi zoletsa zambiri, monga vuto la mercury contact leak, ndipo n'zovuta kupanga ma channel opitilira 8, ndipo mtengo wopangira ndi wokwera kwambiri. Infrared transmission ndi wireless transmission njira zimakhala ndi mavuto osokoneza ma signal, ndipo ma channel amphamvu amphamvu sangathe kutumizidwa mwanjira imeneyi.

Zolumikizirana za mphete zopindika zimatha kugawidwa m'magawo opindika otsika, mphete zopindika zapakati, ndi ma hinge ozungulira okwera malinga ndi kuchuluka kwa chizindikiro chotumizira. Zolumikizira zopindika nthawi zambiri zimangotanthauza mitundu iwiri yoyamba yokha. Zizindikiro zamagetsi zogwirira ntchito za zolumikizirana za mphete zopindika ndi izi: kukana kutenthetsa, kukana kukhudzana, mphamvu ya dielectric ndi crosstalk. Pa mphete zopindika zapakati, chifukwa kuchuluka kwake ndi kwakukulu, chitetezo, kufananiza impedance, voliyumu ya phokoso, ndi zina zotero ziyeneranso kuganiziridwa. Ponena za kapangidwe ka kapangidwe kake, kulumikizana kodalirika kuyenera kutsimikiziridwa poyamba kuti zitsimikizire kuti mizere yonse ilumikizidwa nthawi zonse. Chifukwa chake, kuyendetsa magetsi kwa zinthu zomwe zimagwiritsidwa ntchito pa burashi ndikofunikira kuti zikhale bwino, kupanikizika pa mphete yopindika kuyenera kukhala koyenera, kusinthasintha ndi kugwedezeka kwa mphete yopindika kuyenera kukhala kochepa, kukana kuvala kuyenera kukhala bwino, mphamvu ya kukangana iyenera kukhala yaying'ono, ndipo iyenera kukhala yosavuta kusamalira.

1) Mphete yotsetsereka yotsika: gulu la mphete yotsetsereka yomwe imagwiritsa ntchito kulumikizana kotsetsereka kuti itumize zizindikiro ndi mphamvu zochepa. Mphete zotsetsereka zodziwika bwino ndi mphete zotsetsereka zozungulira ndi mphete zotsetsereka zosiyana. Mphete zoyendetsera zozungulira za mphete zotsetsereka zozungulira zimagawidwa m'magawo athyathyathya ndi mphete zooneka ngati V. Zipangizo za mphete zoyendetsera nthawi zambiri zimakhala zamkuwa, zamkuwa, siliva ndi golide. Maburashi ndi palladium, golide kapena maburashi a waya ophimbidwa ndi golide ndi maburashi ophatikizika amkuwa-graphite. Ngati kuchuluka kwa mphete zotsetsereka kuli kwakukulu, mphete yotsetsereka yozungulira imakhala ndi maburashi awiri apamwamba ndi otsika ndi adaputala yosiyana, koma kukula kwake kwa axial ndi kwakukulu. Kugwiritsa ntchito mphete zotsetsereka zosiyana kumatha kuchepetsa kwambiri kukula kwa axial, voliyumu ndi kulemera. Mphete yotsetsereka yosiyana imakhala ndi maburashi awiri apamwamba ndi otsika ndi adaputala yosiyana. Burashi yapamwamba imazungulira ndi azimuth ya antenna, pomwe burashi yapansi imakhala yokhazikika. Pali magulu awiri a zidutswa zolumikizira zapamwamba ndi pansi pa mbale yolumikizira yosiyana. Zidutswa zolumikizirana zofanana zimalumikizidwa ndi mawaya, ndipo njira yosinthira imagwiritsidwa ntchito kuti liwiro lake lozungulira likhale 1/2 ya liwiro lozungulira la azimuth. Pamene antenna ikuzungulira, mphamvu yamagetsi yomwe imalowa mu burashi iliyonse yapansi imadutsa m'mabwalo amodzi kapena awiri olumikizirana pa differential turntable ndikutuluka kuchokera ku burashi yapamwamba yofanana kuti zitsimikizire kuti dera pakati pa gawo lokhazikika ndi gawo lozungulira limalumikizidwa nthawi zonse. Ufa womwe umavalidwa ndi mphete yolumikizirana yosunthika ungayambitse dera lalifupi pakati pa mphetezo. Chifukwa chake, kapangidwe kake kayenera kuonetsetsa kuti ndikosavuta kuyeretsa, ndipo kapangidwe kophatikizana nthawi zambiri kamagwiritsidwa ntchito pokonza kapena kusintha zigawo zake pamalopo.
2) Mphete yotsetsereka ya ma frequency apakati: gulu la mphete yotsetsereka lomwe limagwiritsidwa ntchito kutumiza zizindikiro ndi mphamvu za radar (makumi a megahertz). Mphete yotsetsereka iyi ili ndi ma frequency apamwamba ndipo imafunika kutetezedwa. Mphete zotsetsereka zachangu kwambiri zitha kugwiritsidwanso ntchito kutumiza zizindikiro pansi pa 12MHz. Mphete imodzi imalumikizidwa ndi kondakitala wapakati, ndipo mphete inayo imalumikizidwa ndi gawo lakunja la chingwe ngati mphete yotchingira. Mphete zotsetsereka za Coaxial nthawi zambiri zimagwiritsidwa ntchito kutumiza zizindikiro pamwamba pa 12MHz. Gawo lopingasa la mphete yotsetsereka iyi ndi looneka ngati groove, lomwe kwenikweni ndi kondakitala wa coaxial wamakona anayi. Palinso mphete yotsetsereka ya ma frequency apakati yokhala ndi capacitive, kondakitala wapakati ndi wozungulira, wothandizidwa ndi insulating pad mu shielding layer, pali mpata pakati pa gawo lozungulira ndi gawo lokhazikika, ndipo sizimakhudzana, ndipo chizindikiro cha ma frequency apakati chimalumikizidwa kudzera mu capacitance. Pankhani ya malire ochepa a antenna rotation, chipangizo chozungulira chingwe chingagwiritsidwe ntchito m'malo mwa mphete yotsetsereka.
