Carrier 3 and gear 4 rotate freely about shaft A. Gear 1 is keyed to shaft A and meshes with planet gear 2 which is made up of two identical gear rims, d and b. Rim d of planet gear 2 meshes with gear 4. Rigidly attached to planet gear 2 is wobble plate a which slides along slanted face c of carrier 3. Planet gear 2 is connected by spherical pair B to fixed link 5. The speeds n₁, n₄ and n₃ of gears 1 and 4, and carrier 3 (in rpm) are related by the equation i₁₄=(n₁-n₃)/(n₄-n₃) where i₁₄ is the transmission ratio and equals i₁₄=z₄/z₁ where z₁ and z₄ are the numbers of teeth of gears 1 and 4.
