What are all of the parameters of a Spur Gear that define its geometry?

(OP)
What are all of the parameters of a Spur gear that define its geometry?

So far I have:
- Number of Teeth
- Shaft hole diameter
- Pressure Angle of the Tooth
- Gear Thickness
- Tooth thickness
- Tooth surface with
- Gear diameter
- tooth length

But I think some of these overlap, like gear diameter and tooth length.

can someone help me conclude a list of parameters that completely define a spur gear's geometry?

thanks

RE: What are all of the parameters of a Spur Gear that define its geometry?

A few more:

Tooth form - involute is the usual default, but there are others
Tooth form relief - ways to modify the base form to avoid tooth-tip interference due to bending
Crowning - to add a cylindrical relief to avoid edge contact
Tooth edge chamfers - cheaper and cruder than Crowning
Fillet radius to decrease bending stress
Tooth surface roughness

There are various errors that are detected and monitored, such as involute form error, tooth-to-tooth pitch error, runout of pitch diameter.
