# Worm-drive ratio and efficiency
# Scope: Ideal worm speed ratio with supplied efficiency; no self-locking prediction.
# Status: illustrative worked example; engineering review pending.
# Inputs are example values. Checks are editable example requirements, not standards.

starts = 2
wheelTeeth = 40
inputSpeed = 1500 rpm
inputTorque = 1 N*m
efficiency = 0.6

ratio := wheelTeeth/starts
speed := inputSpeed/ratio [rpm]
torque := inputTorque*ratio*efficiency [N*m]

check output torque target: torque >= 10 N*m

scenario alternative: starts = 1
