Question

estion- a) Find the speed ratio of the gear train shown in figure. What will be the direction of gear 7 b) Determine pitch line velocity (v r.w) of gear &, provided for gear 6 Imodule (D/T) 5mm e) If double the speed ratio (as calculated in a) is required with a simple gear train (having only two gears) number of teeth on driven gear, provided input gear has 20 teeth. IST IST 25T 33T I8T
An epicyclic gear train is shown in figure below Sun gear has 40 teeth, planet gear has 20 teeth, Ring gear has 80 teeth, arm (EF) is rotating is rotating with 200rpm in clockwise direction, white sun gear is rotating with 100rpm in clockwise direction. (a) Determine velocity (rpm) of planet and ring gears and directions of planet and ring gears (b) Determine pitch line velocity (mm/min) of ring gear (take module DIT Amm) (e) ldentify atleast how many gears are required in a gear train if first driver and last driven gears have same direction and shafts of first driver and last driven gear are coaxial. Identify atleast how many gears are required in a gear train if first driver and last driven gears have same direction and shafts of first driver and last driven gear are not coaxial. (d)
