Hyperboloid Pair: Ideal Effective-Radius Ratio Calculator | FIRGELLI
Compare ideal speed and torque ratios for two effective rolling radii. The tangent-circle illustration does not design hyperboloid surfaces, teeth or skew-axis contact.
Variable Rotary Motion: Ideal Equal-ellipse Gear Speeds
Explore matched equal elliptical pitch curves and calculate cyclic ideal output speed from input speed, eccentricity and phase. Teeth, loads, stress and machine performance are...
Transmission of Two Speeds: Ideal Ratio Comparison
Compare two entered input-to-output speed ratios and their ideal torque multipliers. The calculator does not define a gearbox or simulate shifting.
Hypocyclic Gear Train: Fixed-Ring Count-Ratio Calculator | FIRGELLI
Compare ideal fixed-ring speed-ratio magnitudes and output rotation from ring and inner counts. Tooth profiles, output geometry and load capacity are not calculated.
