# Backlash and output positioning
# Scope: Small-angle conversion of tangential backlash to angular lost motion.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

backlash = 0.1 mm
pitchRadius = 25 mm

angle := backlash/pitchRadius [rad]

check angular budget: angle <= 0.5 deg

scenario alternative: backlash = 0.08 mm


# Diagram dimensions are illustrative; teeth are schematic, not manufacturing profiles.
teeth = 30
module := 2*pitchRadius/teeth [mm]
check whole teeth: abs(teeth-round(teeth)) <= 0
check positive teeth: teeth >= 3
