Mazhinji ema "slip rings" anoshandisa "friction contact" senzira yekubatanidza magetsi. Yakachengeteka, yakavimbika, uye inogona kusangana nehuwandu hwema "channels" anodiwa nevatengi. Ma "slip rings" ari pamusika anowanzo shandisa iyi "contact" fomu. Mamwe anosanganisira mercury contact", "infrared transmission", "wireless transmission", nezvimwewo, izvo zvisiri zvigadzirwa zvakajairika pari zvino, nekuti ma "disc slip rings" akagadzirwa nenzira iyi achiri nemiganhu yakawanda, senge dambudziko rekudonha kwe "mercury contact", uye zvakaoma kugadzira ma "channels" anopfuura masere, uye mutengo wekugadzira wakakwira zvikuru. Infrared transmission uye nzira dze "wireless transmission" dzine matambudziko ekupindirana kwemasaini, uye ma "power channels" emagetsi haagone kutakurwa nenzira iyi.
Masangano eSlip ring anogona kukamurwa kuita ma "low-frequency slip rings", ma "medium-frequency slip rings", uye ma "high-frequency rotating hinges" zvichienderana ne "frequency" yechiratidzo chekutumira. Ma "slip rings" anowanzo reva marudzi maviri ekutanga chete. Zviratidzo zvemagetsi zve "slip ring assemblies" ndeizvi: "insulation resistance", "contact resistance", "dielectric strength" uye "crosstalk". Kune ma "medium-frequency slip rings", nekuti ma "frequency" acho akakwira, "shielding", "impedance matching", "noise voltage", nezvimwewo zvinofanirawo kufungwa nezvazvo. Panyaya yekugadzirwa kwechimiro, "viable contact" inofanira kutanga yaonekwa kuti ione kuti mitsetse yese yakabatana nguva dzose. Saka, "electrical conductivity" yezvinhu zvinoshandiswa pabhurashi inofanirwa kuve yakanaka, "pressure" pa "slip ring" inofanira kunge yakakodzera, "eccentricity" uye "shake" ye "slip ring" inofanira kunge iri diki, "wear resistance" inofanira kunge yakanaka, "friction torque" inofanira kunge iri diki, uye inofanira kunge iri nyore kuchengetedza.
1) Mhete yekutsvedza ine frequency yakaderera: mubatanidzwa wemhete yekutsvedza inoshandisa kubatana kunotsvedza kutumira zviratidzo zvine frequency yakaderera uye simba. Mhete dzinotsvedza dzakajairika idzo mhete dzekutsvedza dzine cylindrical uye mhete dzekutsvedza dzakasiyana. Mhete dzinofambisa dzemhete dzekutsvedza dzine cylindrical dzakakamurwa kuita mhete dzakatsetseka uye mhete dzakaita seV. Zvinhu zvemhete dzinofambisa zvinowanzova mhangura, brass, sirivha nemari yegoridhe. Mabhurashi acho ipalladium, gold alloy kana gold-plated wire brushes uye copper-graphite composite brushes. Kana huwandu hwemhete dzekutsvedza hwakakura, mhete yekutsvedza ine cylindrical ine seti mbiri dzemabhurashi epamusoro neapasi uye differential adapter, asi saizi yayo ye axial yakakura. Kushandiswa kwemhete dzekutsvedza dzakasiyana kunogona kuderedza zvakanyanya saizi ye axial, vhoriyamu uye huremu. Mhete yekutsvedza yakasiyana ine seti mbiri dzemabhurashi epamusoro neapasi uye differential adapter. Bhurashi repamusoro rinotenderera ne azimuth ye antenna, nepo bhurashi repasi rakagadzika. Kune seti mbiri dzezvikamu zvepamusoro nepazasi zvekubatana pa differential adapter plate. Zvikamu zvekubatana zvinoenderana zvakabatana newaya, uye differential mechanism inoshandiswa kuita kuti kutenderera kwayo kuite 1/2 ye azimuth rotation speed. Kana antenna ikatenderera, magetsi anoyerera mubhurashi rega rega rezasi anopfuura nepakati pemasekete maviri ekubatana ari padivi returntable uye anoyerera achibva pabhurashi repamusoro rinoenderana kuti ave nechokwadi chekuti dunhu riri pakati pechikamu chakagadzika nechikamu chinotenderera rinogara rakabatana. Hupfu hunopfekwa nering inotsvedza yekubatana inogona kukonzera kupfupika kwedunhu pakati pemasekete. Nokudaro, chimiro chinofanira kuve nechokwadi chekuti chiri nyore kuchenesa, uye chimiro chakabatana chinowanzo shandiswa kubatsira kugadzirisa panzvimbo yacho kana kutsiviwa kwezvikamu.
2) Mhete yepakati inotsvedza: mutsetse wepakati unoshandiswa kutumira zviratidzo zveradar (makumi emegahertz) uye simba. Mhete iyi ine frequency yakakwira uye inoda kudzivirirwa. Mhete dzinotsvedza dzinomhanya zvakanyanya dzinogona kushandiswawo kutumira zviratidzo zviri pasi pe12MHz. Mhete imwe yakabatana neconductor yepakati, uye imwe mhete yakabatana nechikamu chekunze chetambo sering yekudzivirira. Mhete dzinotsvedza dzinodzivirirwa necoaxial dzinowanzo shandiswa kutumira zviratidzo zviri pamusoro pe12MHz. Chikamu chemhete iyi inotsvedza chakaita segroove, iyo inonyanya kuve coaxial conductor ye rectangular. Kunewo capacitive intermediate frequency slip ring, central conductor ine annular, inotsigirwa ne insulating pad mu shielding layer, pane mukaha pakati pechikamu chinotenderera nechikamu chakagadzika, uye hazvibatane, uye chiratidzo chepakati chinosanganiswa kuburikidza ne capacitance. Kana paine limited antenna rotation range, cable winding device inogona kushandiswa pachinzvimbo che slip ring.
