Based on the variable ratio function

by using the geometric model of pinion cutter

the simple algorithm of tooth profile of effectively solved non-circular gear is proposed.Based on the given variable ratio funct ion

the equation of non-circular gear pitch curve is derived.The equation of tooth profile is determined by the processing principle of slotting gear

and the numerical algorithm and Pro/ E modeling is used to get three-dimensional model of non-circular gear.Meanwhile

based on dynamics simulation software ADAMS

the simulation of gear teeth meshing is analyzed.By means of calculat ions on some examples

it proves the correctness

conciseness

generality and innovat ion of the algorithm.
