nstant distanceapart. Therefore we can have elliptic bevelgears that are very similar to elliptic spurgears, as shown by Fig. 141. The two gearsrevolve on radial shafts through their foci,and the link connects radial shafts throughthe free foci. The velocity ratio is the ratioof the perpendiculars… … Elliptic bevel gears Fig, 14:1, the gear cutting machine of (150), does notapply. 84 Elliptic Calculations. 153.—MATHEMATICAL TREATMENT.
