indlela yokubala imodyuli yegiya

Ukubalaimodyuli yegiya, kufuneka uyazi nokubaisandi esijikelezayo (pp)okanyeububanzi bepitshi (dd)kwaye iinani lamazinyo (zz)Imodyuli (mm) yiparameter eqhelekileyo echaza ubungakanani bezinyo legiya kwaye ibalulekile kuyilo lwegiya. Nazi iifomyula namanyathelo aphambili:

1. Ukusebenzisa i-Circular Pitch (pp)

Imodyuli ibalwa ngokuthe ngqo ukusuka kwiiphimbo elijikelezayo(umgama phakathi kwamazinyo akufutshane kwisangqa sepitch):

m=pπm=πp

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

m=6.28π≈2 mmm=π6.28≈2mm

2. Ukusebenzisa i-Pitch Diameter (ddkunye neNani lamazinyo (zz)

Ubudlelwane phakathi kobubanzi bepitch, imodyuli, kunye nenani lamazinyo bulandelayo:

d=m×z⇒m=dzd=m×z⇒m=zd

Umzekelo:
Ukuba igiya ine-z=30z=Amazinyo angama-30 kunye nobubanzi bepitch d=60 mmd= 60mm, emva koko:

m=6030=2 mmm=3060=2mm

3. Ukusebenzisa iDayamitha yangaphandle (DD)

Kwiigiya eziqhelekileyo,ububanzi obungaphandle (DD)(ububanzi obuvela kwincam ukuya kwincam) bunxulumene nemodyuli kunye nenani lamazinyo:

D=m(z+2)⇒m=Dz+2D=m(z+2)⇒m=z+2D

Umzekelo:
Ukuba u-D=64 mmD=64mm kunye no-z=30z=30, emva koko:

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

Amanqaku aphambili

Amaxabiso asemgangathweni: Soloko ujikeleza imodyuli ebaliweyo kwixabiso eliqhelekileyo elikufutshane (umz., 1, 1.25, 1.5, 2, 2.5, njl.njl.) ukuze uhambelane.

Iiyunithi: Imodyuli ichazwe kwiiimilimitha (mm).

Izicelo:

Iimodyuli ezinkulu (mm) = amazinyo aqinileyo kwimithwalo enzima.

Iimodyuli ezincinci (mm) = iigiya ezincinci zezicelo zesantya esiphezulu/zomthwalo ophantsi.
