Transcript of Perhitungan Tension, Type Dan Size Belt
CARA PENGGUNAAN1 Masukan data data yang tertera pada file Mody2 Data data tsb diambil dari bagian bawah file Mody3 pada kolom 10 (Pd) didapatkan dari Power Motor (Kw) dikalikan dengan coefisien load factor
disesuaikan dengan jenis mesin dan lama jam operational(tabelt Foto Copy)4 sesuaikan "O" ring pada tension pen ,dari hasil perhitungan5 Defleksi pada bagian INCHES/CM,dan Belt tension(Td) Pada kilogram/pound
CARA MENGHITUNG SIZE BELTData Data TeknisGunakan dalam satuan ukur yang sama yaitu Inch/Cm/mmDiameter Pulley Besar : 318 mmDiameter Pulley Kecil : 125 mmCentre Distance (C) : 1016 mm

3 Belt Type : 5V 1080
DATA :
1 = 1016 mm
2 = 318 mm
3 = 125 mm
4 = 1750
5 = 5
6 = 0.2 kg/m
7 See Table = 0.97
( D - d ) : C = 0.190 169 0.97
8 = 5 pcs
9 = 9.8 m/s
10 = 71 KW
STEP 1 : CALCULATE THE SPAN LENGTH
Span Length ( Ls ) = 1011.4 mm
STEP 2 : CALCULATE THE BELT DEFLECTION
= 16.2 mm
STEP 3 : CALCULATE THE BELT SPEED
Belt Speed ( V ) = 11.5 m/s
*) Recommended Max. Belt Speed = 35 m/s, if the Belt Speed exceed than 35 m/s,
STEP 4 : CALCULATE INITIAL TENSION
Initial tension ( Ti ) = 68.8 kgf
STEP 5 : CALCULATE THE BELT TENSION Belt Tension ( Td ) = 6.8 kgf
( New Installation )Belt Tension ( Td ) = 5.9 kgf
