Motocin NEV suna aiki a cikin duniyar manyan RPMs, matsanancin yanayin zafi, girgiza, da buƙatun ingantaccen aiki mai mahimmanci. Kowane bangare, musamman ma wadanda ke tasiri kwanciyar hankali na inji da kuma tsawon rai, dole ne a tsara shi sosai. Maɓuɓɓugan igiyar ruwa ta al'ada suna ba da mafita mai ƙarfi, amma haɗin kai mai tasiri yana buƙatar zurfin nutsewa cikin abubuwa masu mahimmanci da yawa.
1. Gano takamaiman Aikace-aikacen & Aiki
Kafin kowane aikin zane ya fara, clearly define the wave spring's role within the NEV motor:
- Ƙaddamarwa Preload: Mafi yawan aikace-aikacen. Axial preloading na rotor bearings don kawar da ƙarshen wasan, rage girgiza, sarrafa shaft runout, da inganta rayuwa mai girma a manyan RPMs. Wannan yana bukata m kuma daidai force over the motor's operating conditions.
- Load da hatimi: Kula da daidaiton ƙarfi akan hatimin injina, O-zobe, ko hatimin labyrinth don hana zubar ruwa (E.g., mai sanyaya, man shafawa) a cikin mota ko gearbox gidaje.
- Ragewar Jijjiga/ Warewa: Shakewa ko rage girgizawa daga na'ura mai juyi ko wasu abubuwan jujjuyawa don inganta NVH (Surutu, Jijjiga, Tsanani) halaye da kuma kare m kayan lantarki ko tsarin sassa.
- Tazarar Axial / Riƙewa: Samar da takamaiman matsayi na axial ko ƙarfin riƙewa don abubuwan da aka haɗa inda maɓuɓɓugan murɗa na gargajiya suka yi yawa.
- Sadarwar Lantarki (Rare): A wasu lokuta masu niche, idan an yi daga kayan aiki, ana iya amfani da su don matsa lamba, amma wannan shi ne kasa na kowa ga mota takamaiman aikace-aikace.
2. Abubuwan Bukatun Aiki - Mahimmin Ƙarfafawa
Waɗannan su ne manyan direbobin ƙirar raƙuman ruwa:
- Kaya (Karfi) a Specific Deflection:
- Madaidaicin Ƙarfin Ƙarfi: Motocin NEV suna buƙatar takamaiman kayan aiki na musamman. Dole ne ruwan bazara na al'ada ya ba da madaidaicin ƙarfi (E.g., 100 N ± 5 N) a ƙayyadadden tsayin aiki (shigar tsawo).
- Tsawon Tsawon Aiki: What is the spring's minimum and maximum expected deflection during motor operation?
- Ƙididdigar bazara (K):
- Linear vs. Na ci gaba: Yawancin maɓuɓɓugan ruwan raƙuman ruwa suna ba da ƙimar madaidaiciya, amma dangane da daidaitawar kalaman, za a iya samun ɗan ci gaba kaɗan, wanda zai iya zama da amfani ga abubuwan girgiza.
- Rayuwar gajiya:
- Miliyoyin Zagaye: Ana sa ran motocin NEV za su wuce na dubban ɗaruruwan mil, yana nuna miliyoyin hawan hawan bazara. Dole ne a tsara bazara don rayuwar gajiya ta musamman.
- Nazarin damuwa (FEA): Mahimmanci don rage yawan abubuwan damuwa, musamman a kololuwar igiyar ruwa da kwaruruka, don hana gazawar gajiya da wuri.
- shakatawa:
- Karamin Asarar Ƙarfi: Ruwan ruwa dole ne ya kula da ƙayyadaddun nauyin sa a tsawon rayuwarsa gaba ɗaya, musamman a yanayin zafi mai tsayi. Damuwa shakatawa (rarrafe) zai iya haifar da asarar preload, yana cutar da rayuwa ko hatimi mutunci.
- Gudun Aiki (RPM):
- Kaucewa Resonance: The natural frequency of the wave spring should be carefully analyzed to ensure it does not coincide with the motor's operating RPMs or critical harmonic frequencies, hana girgiza mara ƙarfi ko gazawar da ba ta kai ba.
3. Dalilan Muhalli - Kalubalen Motar NEV
Yanayin motar NEV yana da tsauri kuma na musamman:
- Zazzabi:
