Connection coefficient table
| Gear unit load class | Daily operation time (HRS) | |||
| 1-2 | 3-8 | 9-15 | 16-24 | |
| Uniform load | 0.80 | 0.90 | 1.20 | 1.30 |
| Intermediate impact load | 1.00 | 1.20 | 1.30 | 1.50 |
| Heavy impact load | 1.20 | 1.50 | 1.75 | 2.00 |
Basic transmission formula
Reduction ratio (I) | I = N / 1800 |
Slewing speed(RPM) | N = V / πD |
Output torque(KG-M) | T = W x R x K |
Input horsepower (Metric system) | KW1 = N x T / 974 |
Input horsepower (British system) | HP1 = N x T / 716 |
Output horsepower (Metric system) | KW2 = KW1 x F / E |
Output horsepower (British system) | HP2 = HP1 x F / E |
Symbolic explanation
V=speed( M/MIN) | E=efficiency(%) | 1 INCH = 2.54 CM |
I=Reduction ratio | N=Output shaft speed (RPM) | 1 FOOT = 12 INCH |
T=Output torque (KG-M) | D=Roller diameter (MM) | 1 KW = 1000W |
K=Link coefficient | R=Roller diameter radius(MM) | 1 KG-M = 7.233 FT-LB |
F=Load factor | KW1(HP1)=Force horse power | 1 KG = 2.2 LB |
W=Load(KG) | KW2(HP2)=Output horsepower | 1 CM = 10 MM |
