The ratios may each be expressed in a different manner: thus in a train of five axes, let the first revolve once while the second revolves three times;.-= 1 "L% i. Let the second carry a wheel of 60 teeth driving a pinion of 20 on the third; N 60 ns io" Let the third axis drive the fourth by a belt and pair of pullies of 18 and 6 inches diameter respectively; d4 " 6' And let the fourth perform a revolution in ten seconds, and the last in two, when the machinery revolves uniformly; Pt 10 ". "" therefore we have, L,-1 20 6 2 1 Li 3 60 18 X 10 " 135' that is to say, that the first axis will perform one revolution while the last revolves 135-times. 222. In this manner the synchronal rotations of the extreme axes in any given machine may be calculated; their directional relation may also be found, by examining in order the connexion of the axes, and by help of the few remarks which follow. In a train of wheel-work consisting solely of spur-wheels or pinions with parallel axes, the direction of rotation will be alternately to right and left. If therefore the train consist of an even number of axes, the extreme axes will revolve in opposite directions, but if of an odd number of axes, then in the same direction. If an annular wheel be employed, its axis revolves the same way as that of the pinion (Art. 58). 223. If a wheel A (fig. 17, page 42) be placed between two other wheels C and B, it will not affect the velocity ratio of these wheels, which is the same as if the teeth of B were immediately engaged with those of C, but it does affect the directional relation; for if B and C were in contact, they would Tevolve in opp...
