1. Dab tsi yog Wave Spring Washer?
Ntawm nws lub hauv paus, lub caij nplooj ntoos hlav ntxhua khaub ncaws yog ib resilient tivthaiv tsim los nqa axial ua si, dampen kev co, thiab muab ib daim ntawv teev ua ntej load-tag nrho thaum siv qhov chaw axial tsawg tsawg.
- Visual Distinction: Xav txog lub tiaj tus hlau ntxhua khaub ncaws, tab sis es tsis txhob ua zoo kawg nkaus planar, nws nto undulates nce thiab nqis nyob rau hauv maj mam, nruam nthwv ncig nws ncig.
- Ib leeg tig: Tseem ceeb heev, it's generally a ib-tig tiv thaiv. Qhov no txawv nws los ntawm ntau qhov tig "yoj springs" (zoo li cov siv rau cov kabmob preload hauv motors, uas feem ntau nruam coils ntawm tiaj hlau nrog ntau nthwv dej).
- Lub hom phiaj: Thaum compressed, cov nthwv dej no flatten, tsim kom muaj lub caij nplooj ntoos hlav axial.
2. Cov yam ntxwv tseem ceeb & Cov txiaj ntsig
Kev tsim ntawm yoj lub caij nplooj ntoos hlav ntxhua khaub ncaws muaj peev xwm ua tau ntau yam zoo, tshwj xeeb tshaj yog nyob rau hauv compact assemblies:
- Qhov tseem ceeb Axial chaw txuag: Qhov no feem ntau yog thawj vim li cas thiaj xaiv lub tshuab ntxhua khaub ncaws. Nws tuaj yeem muab lub zog caij nplooj ntoos hlav muaj zog hauv qhov chaw axial me me (qee zaum 50% los yog ntau dua) dua li cov pa helical coil caij nplooj ntoos hlav lossis txawm tias Belleville ntxhua khaub ncaws rau qhov zoo sib xws deflection thiab load.
- Axial Take-Up thiab Slack Elimination: Zoo heev rau kev them nyiaj rau kev ua siab ntev stack-up hauv cov rooj sib txoos, tshem tawm kev ua si los yog rattle hauv bearings, iav, los yog lwm yam khoom.
- Precise thiab Consistent Load Delivery: tuaj yeem tsim los muab qhov tshwj xeeb, kwv yees load ntawm ib tug muab deflection.
- Kev vibration Dampening & Shock Absorption: Lub caij nplooj ntoos hlav ua haujlwm pab nqus cov kev cuam tshuam me me thiab ua kom muaj kev vibrations, txhim kho kev sib dhos ruaj khov thiab txo cov suab nrov.
- Dav dav ntawm Deflection & Load Combinations: Los ntawm kev sib txawv ntawm cov nthwv dej, khoom thickness, thiab lwm yam geometric parameter, ib tug dav spectrum ntawm lub caij nplooj ntoos hlav rog thiab deflections tuaj yeem ua tiav.
- Material Versatility: Muaj nyob rau hauv ntau yam ntaub ntawv kom haum ntau haiv neeg tej yam kev mob (kub, corrosion, hlau nplaum).
- Nqi-Zoo: Feem ntau pheej yig dua li kev cai tsim helical springs lossis complex Belleville stacks rau qee yam kev siv.
3. Lawv ua haujlwm li cas
Thaum lub axial quab yuam yog siv rau lub caij nplooj ntoos hlav ntxhua khaub ncaws, nthwv dej pib flatten. Raws li lawv flatten, cov khoom deflects, khaws cia muaj peev xwm zog. Lub zog khaws cia no yog tom qab ntawd tso tawm raws li lub zog muaj zog, thawb rov qab tiv thaiv cov ntaub ntawv thov.
- Tus tus naj npawb ntawm nthwv dej ncaj qha cuam tshuam rau lub caij nplooj ntoos hlav: ntau nthwv dej feem ntau ua rau lub caij nplooj ntoos hlav qis dua (tsawg zog rau ib tug muab deflection) rau ib tug muab khoom thiab thickness, tso cai rau ntau dua deflection. Tsawg nthwv dej ua rau lub caij nplooj ntoos hlav siab dua.
- Tus khoom thickness, dav, thiab sab nraud / sab hauv diameters kuj tseem ua lub luag haujlwm tseem ceeb hauv kev txiav txim siab lub caij nplooj ntoo hlav thiab qhov siab tshaj plaws.
4. Hom Wave Spring Washers
Thaum lub ntsiab lus tseem ceeb yog tib yam, yoj caij nplooj ntoos hlav washers tuaj nyob rau hauv variations kom tau raws li ntau yam kev xav tau:
- Tib Wave Washer: Daim ntawv yooj yim tshaj plaws, feem ntau muab lub caij nplooj ntoos hlav maj mam thiab nruab nrab load peev. Zoo rau lub teeb nqa.
- Ntau Wave Washer (2-, 3-, 4-Wave, lwm.): Muaj ntau lub ncov thiab hav. Feem ntau muaj peev xwm ua tau siab dua thiab lub caij nplooj ntoos hlav khov rau cov khoom siv thiab txoj kab uas hla piv rau ib lub tshuab ntxhua khaub ncaws. Qhov nce hauv nthwv dej tso cai rau ntau dua deflection thiab thauj khoom yam tsis tau nce cov khoom tuab lossis sab nraud.
- Crest-rau-Crest Wave Springs (Multi-Tig Wave Springs): Thaum feem ntau siv interchangeably hauv kev sib tham txog "yoj caij nplooj ntoos hlav tsev neeg," cov no yog technically ib pawg sib txawv. Lawv yog tsim los ntawm cov hlau tiaj tus tsim rau hauv ntau lub coils, nrog txhua tig muaj nthwv dej. Lawv muaj peev xwm deflection ntau dua thiab cov yam ntxwv ntawm kev thauj khoom zoo dua li ib zaug tig yoj lub tshuab ntxhua khaub ncaws tab sis siv qhov chaw axial ntau dua li lub tshuab ntxhua khaub ncaws.. Rau cov ntsiab lus ntawm "wave spring washer," qhov tsom xam feem ntau yog nyob rau ib zaug, discrete washer daim ntawv.
