Gearhead/Linear Head: Radial Load Calculation Formula
The radial load can be calculated using the formula shown below.
$$ {W} = \frac{K \times T \times f}{\gamma}$$
- W
- Radial load [N]
- K
- Load coefficient by driving method (table below)
- T
- Load torque at gearhead output shaft [N·m]
- f
- Service factor
- γ
- Effective radius of gear or pulleys [m]
