Abstract:
Provided are a seal ring and a harmonic reducer, the seal ring comprising: a seal part (32), the seal part (32) being annular and comprising a first seal lip (33), a second seal lip (34) and a connecting segment (35), the first seal lip (33) being elastically deformable relative to the second seal lip (34) along a radial direction (R) of the seal ring; and an elastic part (31), the elastic part (31) comprising a radial outside portion (311) and a radial inside portion (312), the radial outside portion (311) being connected to the first seal lip (33), and the radial inside portion (312) being connected to the second seal lip (34); when the radial outside portion (311) and the radial inside portion (312) are compressed along the radial direction (R) of the seal ring and are thus close to one another, the elastic part (31) causes the first seal lip (33) and the second seal lip (34) to trend away from one another.
