BEVEL GEAR FORMULAS (shaft angle Σ = 90°): Pinion pitch cone angle: tan δ1 = z1/z2 → δ1 = arctan(z1/z2) Gear pitch cone angle: δ2 = 90° − δ1 Mean pitch diameter: dm = m × z × cos δ Where: z1 = pinion teeth | z2 = gear teeth | m = module | δ = pitch cone half-angle WORKED EXAMPLE: z1=20 | z2=40 | m=3 tan δ1 = 20/40 = 0.5 → δ1 = 26.57° δ2 = 90° − 26.57° = 63.43° dm1 = 3 × 20 × cos(26.57°) = 53.7mm dm2 = 3 × 40 × cos(63.43°) = 53.7mm (always equal — confirming calculation) KEY BEVEL GEAR RULE: Both gear mean pitch diameters must be equal for correct mesh
