Time left 0742 Question 2: (20%) An epicyclic gear consists of gears A, B and C as shown in the Figure, The three planet gears B mesh with both A and Cand is carried on the Arm The Ring gear A has 80 internal teeth, and the Sun Gear C has 40 external teeth B -A Arm
a. Complete the missing data in the following table : (6xl= 6 points) Arm Gear Gear B Gear A Speed RPM 0 XX 0 x +Y Y X+Y b. How many teeth for gear B, TB = Teeth, (4 points) c. If the Arm is rotating about the center of A at 32 r.p.m. CCW and the Sun Gear Cis fixed Find: The rotational speed of the Gear A, NA= I.p.m • direction, (3+2 = 5 points) The rotational speed of the Gear B, NB = I.p.m., direction (3+2=5 points)
