Chirongwa Chekugadzirisa Kudzivirira Kudedera kweDrum yeSlip Ring yeMotokari dzeMigodhi

tekinoroji huru | Indasitiri itsva | Kurume 4, 2025

Ⅰ. Matambudziko emamiriro ekunze ekutenderera kwemidziyo yekuchera migodhi kune sisitimu ye slip ring

Mota dzemigodhi dziri kushanda zvakaoma uye dzine vibration yakawanda (20-2000Hz), impact instantly (peak acceleration ≥15g) uye guruva >30mg/m³ kwenguva yakareba ‌4. Ma "slip ring reels" echinyakare anowanzo chinja-chinja contact resistance (±15%), kuwedzera kwesignal error rate (>5‰) uye mamwe matambudziko munzvimbo iyi, izvo zvinogona kukonzera tsaona dzemotokari muzviitiko zvakakomba. Sekureva kwedata kubva kumugodhi wemhangura wakavhurika muna 2024, "slip ring" isina kurongwa inokonzerwa ne "slip ring failure" inokwana 38% yenguva yese yekukundikana ‌.

Ⅱ. Mhinduro dzetekinoroji huru dzekushandura kusingapindi kudedera

a. Kuvandudzwa kwechimiro chemhete inotsvedza isingakanganiswe nemhedzisiro
Shandisa dhizaini ye "buffer" ine nhanho nhatu:
Rutivi rwekubatana: beryllium bronze alloy contacts dzakaiswa (kuomarara HV220), ne hyperbolic raceway design, kushanduka kwesimba rekubatana kunodzorwa mukati me ±3N
Chigadziko chekutumira: module yekudzikisa damping yediski yakabatanidzwa, inogona kutora simba rekukurumidza (> 8J), chiyero chekutumira vibration chinoderedzwa kusvika 0.35
Chigadziko chekuisa: chakagadzirirwa ne polyurethane-simbi composite base, kusimbiswa kwerabhoritari kunogona kuderedza 20Hz vibration amplitude ne62%

Dhayagiramu yekufananidzira yekuedza kuvhunduka uye kudedera

b. Kugadziriswa kwehurongwa hweEMC certification system yemichina yekuchera
Chirongwa chekushandura chinotevedzera zvakadzama mwero weGB/T 3836.4-202X wekushandiswa kwemagetsi asingapindi kuputika:
Isa chifukidziro chekudzivirira chine mativi akawanda (kushanda zvakanaka kwekudzivirira ≥70dB@1GHz)
Gadzirisa topology ye wiring uye deredza voltage ye common mode interference kubva pa 12V kusvika 0.8V
Kupasa bvunzo yekudzivirira kudzivirirwa kwemwaranzi ye10V/m, chiyero chekukanganisa kwebit chiri <0.1‰ (1.2‰ isati yashandurwa)

c. Inodzivirira mvura uye inodzivirira guruva mhete yakabatanidzwa mhinduro
Inoshandisa tekinoroji yekubatanidza chisimbiso ine simba:
Chisimbiso chikuru: fluororubber rotary seal ring (kuramba kupisa -40℃ ~180℃)
Chisimbiso chekubatsira: chimiro chechidzitiro chemhepo che labyrinth (musiyano wekumanikidzwa kwemhepo 0.05MPa) Kusvika padanho rekudzivirira re IP68, kushanda nguva dzose pasi pekuyerera kwemvura ine guruva (50L/min) kwemaawa anopfuura 2000 pasina kubuda kwemvura.

Mufananidzo wemhete inotsvedza isingapindi mvura uye inodzivirira guruva

III. Ruzivo rwekuitwa kwepurojekiti nekusimbisa

Chirongwa chekushandura chakaitwa mumugodhi wesimbi muna Gumiguru 2024 chinoratidza:
Kushivirira kutenderera: Mubvunzo wekudengenyeka unoenderera kwemaawa masere (frequency 50Hz, amplitude 2mm), kugadzikana kwekutumira kwechiratidzo kwakawedzera ne83%.
Dziviriro yekurohwa nehana: Kutevedzera mamiriro ekudonha kwemotokari yemugodhi (kudonha pasina rusununguko kubva pakukwirira kwe1.2m), mwero wekuvimbika kwezvikamu zvakakosha ndeye 100%
Mari yekushandisa nekugadzirisa: Nguva yekugadzirisa rin'i inowedzerwa kubva pamaawa mazana mashanu kusvika kumaawa mazana maviri, uye kushandiswa kwezvikamu zvepagore kunoderedzwa ne47%.

main technical parameters

Index	Pamberi	Mushure me	Kuvandudzwa
Kutapurirana kwekudengenyeka	0.78	0.35	55%↓
Mwero wekukanganisa kwechiratidzo (‰)	5.2	0.09	98%↓
Dziviriro	IP54	IP68	Inodzivirira guruva/inodzivirira mvura
Kuramba kukanganiswa (g)	8	15	87%↑

Ⅳ. Kuwedzerwa kwehurongwa hwekugadzirisa hwakangwara

Chinongedzo che vibration cheimplant (chiyero chemuenzaniso 10kHz) chekutarisa mamiriro e slip ring munguva chaiyo
Gadzira modhi yekuongorora hutano kuti ufanotaura nemazvo hupenyu hwebasa rasara (chikanganiso <8%)
Kuongororwa kwe electromagnetic interference spectrum ye 20 equipment clusters kuburikidza ne EMC cloud platform

Mhedziso

Mhinduro iyi inovaka sisitimu yakakwana yekudzivirira kudedera kuburikidza nehunyanzvi hwekudzivirira kukuvadzwamhete yekutsvedzachimiro, kugadziriswa kwehurongwa hweEMC certification system yemichina yekuchera migodhi uye kubatanidzwa kwemhete isingapindi mvura uye inodzivirira guruvatekinoroji. Ruzivo rwechokwadi rwekuyedza runoratidza kuti nguva iri pakati pekukundikana kwemidziyo (MTBF) mushure mekushandurwa yakawedzera kubva pamaawa 1800 kusvika kumaawa 5200, zvichipa hwaro hwakanaka hwekushandurwa kwemugodhi zvine hungwaru.
