yuav ua li cas xam cov iav module

Yuav xam qhoviav module, koj yuav tsum paub los yoglub voj voog ncig (pp)los yog lublub suab diameter (dd)thiab lubtus naj npawb ntawm cov hniav (zz)Lub module (mm) yog ib qho kev ntsuas tus qauv uas txhais qhov loj ntawm cov hniav iav thiab yog qhov tseem ceeb rau kev tsim iav. Hauv qab no yog cov qauv tseem ceeb thiab cov kauj ruam:

1. Siv Lub Suab Sib Npaug (pp)

Lub module yog xam ncaj qha los ntawmlub voj voog(qhov deb ntawm cov hniav sib ze raws lub voj voog suab):

m = pπm=πp

Piv txwv:
Yog tias p = 6.28 hlip= 6.28 hli, ces:

m = 6.28π≈2 hlim=π6.28 ≈2 hli

2. Siv Qhov Ntev ntawm Lub Suab (dd) thiab Tus Naj Npawb ntawm Cov Hniav (zz)

Qhov kev sib raug zoo ntawm lub suab diameter, module, thiab tus naj npawb ntawm cov hniav yog:

d=m×z⇒m=dzd=m×z⇒m=zd

Piv txwv:
Yog tias lub iav muaj z = 30z= 30 hniav thiab lub suab ntawm lub suab d = 60 mmd= 60 hli, ces:

m = 6030 = 2 hlim=3060=2 hli

3. Siv Txoj Kab Uas Ntev Sab Nraud (DD)

Rau cov iav txheem, covsab nraud txoj kab uas hla (DD)(txoj kab uas hla ntawm lub taub hau mus rau lub taub hau) muaj feem cuam tshuam rau lub module thiab tus naj npawb ntawm cov hniav:

D=m(z+2)⇒m=Dz+2D=m(z+2)⇒m=z+2D

Piv txwv:
Yog tias D = 64 hliD=64 hli thiab z = 30z= 30, ces:

m = 6430 + 2 = 6432 = 2 hlim=30+264=3264=2 hli

Cov Lus Qhia Tseem Ceeb

Cov Nqi Txheem: Ib txwm muab cov module uas xam tau los sib npaug zos rau tus nqi tus qauv ze tshaj plaws (piv txwv li, 1, 1.25, 1.5, 2, 2.5, thiab lwm yam) rau kev sib xws.

Chav: Module tau qhia nyob rau hauvmillimeters (hli).

Cov ntawv thov:

Cov modules loj dua (mm) = cov hniav muaj zog dua rau cov khoom hnyav.

Cov modules me dua (mm) = cov iav me me rau kev siv ceev ceev / thauj khoom tsawg.
