# Gears
|
|
|
|
|
|
|
|
|
|
- pinion in gear pair is small one
|
|
|
|
|
- there are two important stresses in gears: bending and contact stresses
|
|
|
|
|
|
|
|
|
|
$$\sigma = \frac{W_t}{K_vFmY}$$
|
|
|
|
|
|
|
|
|
|
where $K_v = \frac{6.1}{6.1+V}$, $W_t = \frac P V$ is transmistted load, $F$ is face width, $m$ is
|
|
|
|
|
module, $Y$ is Lewis factor
|
|
|
|
|
|
|
|
|
|
where $V$ is pitch line velocity
|
|
|
|
|
|
|
|
|
|
## Gear Trains
|
|
|
|
|
|
|
|
|
|
A gear train is a collection of two or more gears.
|
|
|
|
|
|
|
|
|
|
This is used to go beyond the typical limit of two meshing gears (~10:1).
|
|
|
|
|
|
|
|
|
|
### Simple Gear Train
|
|
|
|
|
|
|
|
|
|
The train ratio of a simple gear train is always $\frac{N_{input}}{N_{output}}$.
|
|
|
|
|
|
|
|
|
|
An idler gear may be used to change rotation of the output shaft.
|
|
|
|
|
|
|
|
|
|
### Compound Gear Trains
|
|
|
|
|
|
|
|
|
|
Having parallel arrangements leads to the intermediate gears not being cancelled out.
|
|
|
|
|
|
|
|
|
|
A general formula is
|
|
|
|
|
|
|
|
|
|
$$m_y = \frac{\Pi N_{driver}}{\Pi N_{driven}}$$
|
|
|
|
