indlela yokubala imodyuli yegiya

Ukubalaimodyuli yegiya, udinga ukwazi noma yikuphiiphimbo eliyindilinga (pp)nomaububanzi bephimbo (dd)kanyeinani lamazinyo (zz)Imojuli (mm) iyipharamitha ejwayelekile echaza usayizi wezinyo legiya futhi ibalulekile ekwakhiweni kwegiya. Ngezansi amafomula nezinyathelo ezibalulekile:

1. Ukusebenzisa i-Circular Pitch (pp)

Imodyuli ibalwa ngqo kusukela ku-iphimbo eliyindilinga(ibanga phakathi kwamazinyo aseduze eduze kwesiyingi sephimbo):

m=pπm=πp

Isibonelo:
Uma i-p=6.28 mmp=6.28mm, bese kuba:

m=6.28π≈2 mmm=π6.28≈2mm

2. Ukusebenzisa Ububanzi Bephimbo (ddkanye nenani lamazinyo (zz)

Ubudlelwano phakathi kobubanzi bephimbo, imodyuli, kanye nenani lamazinyo yilokhu:

d=m×z⇒m=dzd=m×z⇒m=zd

Isibonelo:
Uma igiya line-z=30z=amazinyo angu-30 kanye nobubanzi bephimbo d=60 mmd=60mm, bese kuba:

m=6030=2 mmm=3060=2mm

3. Ukusebenzisa Ububanzi Bangaphandle (DD)

Kumagiya ajwayelekile,ububanzi bangaphandle (DD)(ububanzi be-tip-to-tip) buhlobene ne-module kanye nenani lamazinyo:

D=m(z+2)⇒m=Dz+2D=m(z+2)⇒m=z+2D

Isibonelo:
Uma u-D=64 mmD=64mm kanye no-z=30z=30, bese kuba:

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

Amanothi Ayisihluthulelo

Amanani Ajwayelekile: Njalo zungeza imodyuli ebaliwe uye enanini elijwayelekile eliseduze (isb., 1, 1.25, 1.5, 2, 2.5, njll.) ukuze uthole ukuhambisana.

Amayunithi: Imojuli ivezwa kuamamilimitha (mm).

Izicelo:

Amamojula amakhulu (mm) = amazinyo aqinile kakhulu emithwalweni esindayo.

Amamojula amancane (mm) = amagiya amancane okusetshenziswa ngesivinini esikhulu/umthwalo ophansi.
