Waa maxay guga fidsan?

Waxaad u baahan tahay xoog wareeg ah laakiin waxaad haysataa meel aad u yar oo xagal ah. Halbeeg, bulky round-wire torsion spring simply won't fit, ku qasbida in dib u habayn buuxda lagu sameeyo alaabtaada is haysta.

Isha torsion-ka fidsan waa il kasta oo laga sameeyo fiilooyin fidsan, sida birta guga, kaas oo kaydiya oo sii daaya tamarta wareegta. Muuqaalkeeda caato ah ayaa ka dhigaysa mid ku habboon codsiyada leh xannibaadaha meel bannaan.

Marka uu injineer ii soo diro sawir loogu talagalay "flat torsion spring," su'aashayda koowaad waa had iyo jeer, "Maxay dhab ahaan u baahan tahay in la sameeyo?" Eraygu waa qayb guud, ma aha qayb gaar ah. It's like asking for a "car" when you need to specify if it's a truck, sedan, ama baabuur isboorti. Doorashada nooca saxda ah ee guga fidsan waa mid ka mid ah go'aamada ugu muhiimsan ee lagu hubinayo in habkaagu u shaqeeyo si habsami leh oo la isku halleyn karo nolosha adeegga oo dhan..

Waa guga Spiral Torsion oo la mid ah guga Torsion Flat?

You're looking for a simple return spring, laakiin erey-bixintu waa wareer. Waxaad arkaysaa ilo fidsan oo kala duwan oo isku duuban oo waxaad mooddaa inay isku si u shaqeeyaan, taasoo keeni karta in la dalbado qayb qaldan.

A spiral torsion guga[^ 1] waa mid gaar ah nooca ee guga torsion flat[^ 2]. It's designed with open coils that do not touch and is best suited for low-rotation applications, caadi ahaan ka yar 360 shahaadooyinka.

Waxaan xusuustaa la shaqeynta shirkad soo saareysay qalabka xakamaynta dhamaadka-sare ee qalabka maqalka. Waxay rabeen si siman, taabto "ku-noqoshada-dhexda" dareemo. Waxay markii hore isku dayeen il koronto oo yar, laakiin waxa ay siisay wareeg aad u badan waxana ay dareemeen iswaafaq la'aan. Xalku wuxuu ahaa il torsion oo dhab ah. Waxaan naqshadeynay mid siinaya qadar sax ah oo wareeg ah oo ka badan wareeg 45-degree ah. Farqiga u dhexeeya gariiradaha ayaa hubiyay inaysan jirin wax khilaaf ah, siinta buro in premium, dhaqdhaqaaq dareere ah oo ay raadinayeen.

Tilmaamaha qeexida

Furaha guga torsion-ga rogaal-celinta waa mid fudud, design gariiradda furan. Waa qurux iyo waxtar u leh hawlo gaar ah.

• Dhismaha: It's made from a single strip of rectangular spring steel coiled on one plane. Hal dhammaad ayaa sida caadiga ah foorarsan si uu u sameeyo barroosin gudaha ah (in lagu dhejiyo usheeda dhexe), iyo dhamaadka kale waxaa loo sameeyay in lagu riixo qaybta wareega.
• Shaqada: Sida qaybtu isu beddesho, waxay dabaysha guga sii adkaynaysaa, foorarsiga alaabta. The material's resistance to this bending creates the restoring torque. Sababtoo ah gariiradaha looma talagelin inay taabtaan, jawaab-celinta qulqulka ayaa ah mid toosan oo siman oo leexashada yaryar ah. Looma jeedo codsiyada u baahan rogrogo badan.

Goorma Ayaa Awoodeedu (Xilliga Guga) Doorashada saxda ah?

Alaabtaadu waxay u baahan tahay inay dib u celiso xadhig dheer ama suunka, Kaas oo u baahan wareegyo badan oo buuxa. Iga wareega ee fudud ayaa isku xiri doona oo fashilmi doona ku dhawaad ​​isla markiiba.

il koronto, sidoo kale loo yaqaan isha saacada, waa doorashada saxda ah ee dib u noqoshada wareega-sare. Noocan ah guga torsion flat[^ 2] waa la sii adkeeyay oo waxay ku jirtaa guri, taas oo u oggolaanaysa in ay soo gudbiso torque joogto ah oo badan.

Mid ka mid ah macaamiisheena ugu weyn ayaa soo saara qalabka warshadaha, oo ay ku jiraan tuubooyinka hawada dib loo celin karo ee siminaarada. Ilaha ku dhex jira gariiradan waa qaybo halis ah. Waa inay dib u soo laabtaan 50 cagaha tuubada culus si habsami leh oo kumanaan jeer lagu kalsoonaan karo. Tani waa codsiga caadiga ah ee a il koronto[^ 3]. Isha ayaa si adag ugu dhaawacan gudaha durbaan. Markaad soo jiidato tuubada, gu'gu wuu sii adkaanayaa. Markaad sii dayso, tamarta kaydsan ayaa dib u soo jiidaya tuubada. A simple spiral spring couldn't store enough energy or provide enough turns to do that job.

Muhiimadda Guriyeynta

Si ka duwan guga wareega ee fudud, a il koronto[^ 3] waa nidaam dhamaystiran oo ku tiirsan guriyihiisa inay si sax ah u shaqeeyaan.

• Kaydinta Tamarta: A il koronto[^ 3] waxa laga sameeyaa xariijimo dheer oo walax ah oo hore loogu sameeyay gariirad cidhiidhi ah. Ka dib waxaa lagu rakibaa guri ama kiis wax yar ka weyn dhexroorkiisa bilaashka ah. Habkani "hore-loads" guga tamar leh.
• Xumaan iyo Xakamaynta: Sida gu'gu u shaqeeyo, gariiradaha ayaa isku cadaadiya midba midka kale iyo gudaha guriga. Khilaafkan la xakameeyey waa qayb ka mid ah naqshadaynta waxayna caawisaa abuurista faan, qalooca qulqulka badan ee joogtada ah marka loo eego guga wareega. Tani waa sababta aad u hesho jiid joogto ah oo ka soo jeeda cabbirka halkii aad ka heli lahayd xoog si degdeg ah u dhacaya.

Ma u isticmaali kartaa Bar Flat Fudud sidii Guga Torsion ahaan?

Waxaad u baahan tahay mid aad u fudud, il-qiimihiisu jaban yahay oo loogu talagalay habka dhuuban ama daboolka aasaasiga ah. Isha duuban waxay u egtahay mid ka badan, and you're wondering if there's a simpler way.

Haa, bar torsion flat ah waa qaabka ugu fudud ee il torsion flat ah. It's a straight strip of spring material that provides a restoring torque when twisted, samaynta ku haboon fudud, codsiyada wareeg yar.

Mar waxaan ka shaqeeyay mashruuc u shaqaynaya soo saaraha qalabka beeraha. Waxay u baahdeen il loogu talagalay habka xidhitaanka ee daboolka abuurka abuurka. Waxay ahayd mid adag, deegaanka wasakhaysan, farsamaduna waa inay ahaato mid nacas ah oo raqiis ah. We didn't use a coiled spring at all. Waxaan naqshadeynay gaaban, gabal toosan oo bir guga fidsan oo adag. Mid ka mid ah cidhifyada ayaa lagu almaray jilbiska, kii kalena wuxuu ku dul istaagay daboolka. Markaad furka furtay, waxay maroojisay baarka. Markaad fasaxday, Baarku ma leexleexan oo daboolkii ayuu xidhay. Waxay ahayd si cajiib ah u fudud, kharash ku dhawaad ​​waxba in la sameeyo, waxayna u badan tahay inay ka dheeraan doonto inta kale ee mishiinka.

Fududeynta Naqshadaynta

Mararka qaarkood xalka ugu waxtarka badan waa kan leh qaybaha ugu yar. Bar torsion-ka fidsan ayaa tusaale fiican u ah mabda'an.

• Sida ay u shaqeyso: Bar torsion-ka waxay ku shaqeysaa iska caabin torsional ah (maroojin) ciidamada dhererkeeda. Si ka duwan ilo xayndaab leh oo kaydiya tamarta iyaga oo laabta alaabta, a torsion bar[^4] kaydiya tamarta iyada oo maroojin. Qadarka qulqulka ay bixiso waxaa lagu go'aamiyaa dhererkiisa, dhumucdiisuna, ballac ahaan, and the material it's made from.
• Codsiyada: Naqshadani waxay ugu fiican tahay xagasha hoose, Codsiyada la isku halleyn karo ee sare ee meesha bannaan ee gariiradda aysan jirin. It's often found in vehicle suspensions, qabsooyin waara, clips batari qalab, iyo dheellitirnaanta hinge-ga fudud. Faa'iidada ugu weyn waa adkeysigeeda xad dhaafka ah iyo qiimaha jaban.
