WILCOX-RICH CORPORATION Division of Eaton Manufacturing Company 4. Mr. W. A.{Mr Adams} Robotham December 27, 1937 9. Lift on flank: l_fl = E_fl x (1 - cos β') ¢ 10. Lift on involute: l_i = .0174533 x D/2 x B° 11. Total lift: l = l_fl + l_i + l_p 12. Base circle radius: R_B = R_N + R_W - l .0174533 is conversion factor. written as degrees. degrees to radians. | ||
