1. Fa'atatauga o galuega fa'atatauga
1.tgθ=b/a ctgθ=a/b
2. Agasalaθ=b/c Cos=a/c
2. Fuafuaina o le saosaoa tipi
Vc=(π*D*S)/1000
Vc: laina saoasaoa (m/min)
π: pi (3.14159)
D: le lautele o meafaigaluega (mm)
S: saoasaoa (rpm)
3. Fuafuaga o le aofa'i o fafaga (tau F)
F=S*Z*Fz
F: Aofa'i fafaga (mm/min)
S: saoasaoa (rpm)
Z: numera o lau
Fz: (fafaga moni i le pito)
4. Fuafuaga o mea maualuga o totoe
Scallop=(ae*ae)/8R
Scallop: maualuga meafaitino totoe (mm)
ae: XY maualuga (mm)
R fua o meafaigaluega (mm)
5. Fuafuaga o mea e sao ai pu
Φ=√2R2
X, Y=D/4
Φ: le lautele o le pu sola (mm)
R fua o meafaigaluega (mm)
D: le lautele o meafaigaluega (mm)
Ono, o le fuafuaina o le aofaʻi o meafaitino
Q=(ae*ap*F)/1000
Q: Aofaiga o fafaga (cm3/min)
ae: XY maualuga (mm)
ap: Z maualuga (mm)
7. Fa'atatauga o mea'ai ile lau
Fz=hm * √(D/ap )
Fz: Fafaga fa'atino ile lau hm: Fafaga fa'ata'ita'i ile lau ap: Z pitch(mm)
D: le lautele o lau (mm)
8. Oti pito faiga faiga
O'o'o le fa'agaoioiga mata'i = mafiafia ipu – maualuga pito pito + pito vili (0.3D)
D o lona uiga o le lautele o meafaigaluega
9. Fuafua taimi viliina
T(min)=L(min)/N(rpm)*f(mm/rev)
=πDL/1000vf
L: Umi ole pu
N: Numera o suiga
f: Fa'aputu aofa'i o fafaga
D: vili le lautele
v: tipi saosaoa
Laulau fa'atatau fa'avili fz
lautele mm
Fafaga mm/rev
1.6~3.2
0.025~0.075
3.2~6.4
0.05~0.15
6.4~12.8
0.10~0.25
12.8–25
0.175~0.375
sili atu i le 25
0.376~0.625
10. Fuafuaga fa'atatau o nifo fa'agaau
1 inisi = 25.4mm = 8 points
Sefulutasi, solofanua malosi (fana fana)
W=Md*N/97.410
W: mana mana'omia (KW)
Md: Tosi (kg-cm)
N: numera o ta'amilosaga (rpm)
12. O le fua fa'atatau o le torque e fa'apea:
Md=1/20*f*ps*r2
f o le fua fafaga mm/rev coefficient
r o le laina o le vili (mm)
α: tipi le fua faatatau ps. I fafaga laiti, o le uamea lautele o 500kg/m㎡; o le u'amea lafo lautele e 300kg/m㎡;
