PROBLEM TO BE SOLVED: To provide a differential arrangement enabled to perform an equal torque distribution and an equal differential rotation by using a first external tooth gear meshing with a first internal gear for rotations and revolutions, and a first external tooth gear for rotations in meshing with a second internal tooth gear rotatable integrally with the first external gear.SOLUTION: The individual internal teeth of first and second internal tooth gears and the individual external teeth of first and second external tooth gears are wholly formed of circular arc tooth shapes, and it is set that R1:R2:R3:R4=4:3:3:2 or that R1:R2:R 3:R4=3:2:4:3, when the pitch radius of the first internal tooth gear is set at R1, the pitch radius of the first external tooth gear is set at R2, the pitch radius of the second internal tooth gear is set at R3, and the pitch radius of the second external tooth gear is set at R4.SELECTED DRAWING: Figure 2 |
