Abstract
Assuming that Nand Nare the respective numbers of pinion rollers (); ρis the ratio between the inner diameter of a ring roller () and the outer diameter of a sun roller (); and ρis the ratio between the inner diameter of a ring roller () and the outer diameter of a sun roller (); and it holds that N=3, and (ρ+1)×(ρ+1)≧24+16×2, in the case where N=3, then it holds that ρ≧0.102×(ρ+1)×(ρ+1)+1.196, and ρ≦min[0.204×(ρ+1)×(ρ+1)+3.123, 7+4×3], and in the case where N=4, then it holds that ρ≧(2−2)×(ρ+1)×(p+1)/4−1, and ρ≦min[0.185×(ρ+1)×(ρ+1)+1.320, 7+4×3].
