Bevel pin wheel 1 rotates about fixed axis A and carries pins a which mesh with teeth d of bevel gear 2. Gear 2 rotates about fixed axis B. The mechanism transmits rotation between intersecting axes A and B. The transmission ratio between wheel 1 and gear 2 is i₁₂=ω₁/ω₂=z₂/k where ω₁ and ω₂ are the angular velocities of wheel 1 and gear 2, z₂ is the number of teeth d of gear 2 and k is the number of pins a of wheel 1.
