Question

If, in the epicyclic gear train shown in Fig 4. .gear A rotates at 1000rev/min clockwise, while E rotates at 500 rev/min anticlockwise, determine the speed and direction of rotation of the annulus D, and of the shaft F. All gears are of the same pitch, and the number of teeth in A is 30, in B is 20 and in E is 80. (U. Lond.) (Answer: 372 rev/min anticlockwise; 40rev/min clockwise) Fio. A

Answer 1

Speed of Shaft F = 40 rev/min (Clockwise Direction)

Speed of the annulus D = 371.4 rev/min (Anti-clockwise direction)
