Allowable overhang load
When mounting a sprocket, gear, belt, etc. on the input shaft, use the following formula to check that the overhang load acting on the shaft is below the allowable overhang load (Table 1).
Allowable OHL ≧ T×f×Lf R
OHL: Overhanging Load N{kgf}
T: Input torque N・m{kgf・m}
f: Transmission element coefficient
Lf: Coefficient depending on the load operating position
R: Pitch circle radius of sprocket, gear, V-pulley, etc. m
Table 2 Transmission element coefficient (f)
| Chain | 1.00 |
|---|---|
| gear | 1.25 |
| V-belt | 1.50 |
| Flat belt | 2.50 |
Table 3: Load coefficient (Lf) depending on load application position
| ℓ/QH | 0.5 or less | 0.75 | 1 |
