Title:
DIFFERENTIAL DEVICE
Document Type and Number:
WIPO Patent Application WO/2016/013314
Kind Code:
A1
Abstract:
A differential device, wherein all internal teeth (3a, 5a) of first and second internal gears (3, 5) and external teeth (4a, 6a) of first and second external gears (4, 6) are formed in a circular arc tooth shape and wherein the formula R1: R2: R3: R4 = 4 : 3 : 3 : 2 or R1: R2: R3: R4 = 3 : 2 : 4 : 3 is satisfied, where R1 is the pitch circle radius of the first internal gear (3), R2 is the pitch circle radius of the first external gear (4), R3 is the pitch circle radius of the second internal gear (5), and R4 is the pitch circle radius of the second external gear (6). Thus, it is possible to provide a differential device capable of equal torque distribution and equal differential rotation using the first external gear, which rotates on its axis and revolves in mesh with the first internal gear, and the first external gear, which rotates in mesh with the second internal gear that is rotatable integrally with the first external gear.
