INDLELA YOKUXELISA INDLELA YOKUZIPHATHA

Ukubala iImodyuli yeGear, kufuneka uyazi ukubaI-pitch esejikelezwe (pp)okanyeUbubanzi be-pitch (dd)kwaye iInani lamazinyo (zz). Imodyuli (mm) Ngaba iParameter esemgangathweni echaza ubungakanani bezinyo zegiya kwaye ibalulekile kwi-Gearti yoyilo. Apha ngezantsi kukho iifomumu eziphambili kunye namanyathelo:

1. Sebenzisa isandi sesangqa (pp)

Imodyuli ibaliwe ngokuthe ngqo kwiI-pitch esejikelezayo(umgama phakathi kwamazinyo akufuphi kwisangqa se-pitch):

m = pπm=πp​

Umzekelo:
Ukuba i-P = 6.28 mmp= 6.28mm, emva koko:

m = 6.28π≈2 mmm=π6.28 ≈2mm

2. Sebenzisa ububanzi be-pitch (dd) kunye nenani lamazinyo (zz)

Ubudlelwane phakathi kobubanzi be-pitch, imodyuli, kunye nenani lamazinyo yile:

d = m × smm = dzd=m×z⇒m=zd​

Umzekelo:
Ukuba igiya i-Z = 30z= Ama-30 amazinyo kunye ne-pitch diemeter d = 60 mmd= 60mm, ke:

m = 6030 = 2 mmm= 3060 = 2mm

I-3. Sebenzisa i-diameter engaphandle (DD)

Ngeegires ezisemgangathweni, ii-diemeter engaphandle (DD)(Inqaku le-Tip-to-Tit) lihambelana nemodyuli kunye nenani lamazinyo:

D = m (z + 2) Orm = DZ + 2D=m(z+2) ⇒ ⇒ ⇒m=z+2D​

Umzekelo:
Ukuba u-D = 64 mmD= 64mm kunye z = 30z= 30, emva koko:

m = 6430 + 2 = 6432 = 2 mmm= 30 + 264 = 3264 = 2mm

Amanqaku aphambili

Amaxabiso asemgangathweni: Soloko ujikeleza imodyuli ebaliwe kwixabiso eliphantsi (umz, 1, 1.25, 1.5, 2, 2, 2.5, njl.).

Iiyunithi: Imodyuli ibonakalisiweIimilimitha (mm).

Izicelo:

Iimodyuli ezinkulu (mm) = amazinyo awomeleleyo kwimithwalo enzima.

Iimodyuli ezincinci (mm) = I-compact ye-compact kwizicelo eziphakamileyo / zomthwalo ophantsi.

Isishwankathelo samanyathelo

Ukulinganisa okanye ukufumana pp, Dd, okanye DD.

Sebenzisa ifomula efanelekileyo ukubala mm.

Mjikelezi mmkwixabiso lemodyuli elikufutshane.

Oku kuqinisekisa ukuba uyilo lwakho lweGear General kunye neMigangatho yeShishini kunye neemfuno zomsebenzi.
