In order to change the direction of rotation a planetary gear is fitted with a compound planet gear arrangement as indicated in the sketch. The motor driving the gearbox has a capacity of 5 kW. The sun has 24 teeth driving Gear 4 with 58 teeth. Gear 3 has 21 teeth driving Gear 5 having 19 teeth driving the ring gear with 110 teeth. Determine: (a) The speed and direction of the ring gear if the sun is rotated by the engine at 300 rpm clockwise and the arm is locked. (b) The speed of the arm if the sun is rotated as in "a" and the ring gear at 50 rpm counter clockwise. (c) The torque available on the ring gear for the case described in "a".

Transcribed Image Text:In order to change the direction of rotation a planetary gear is fitted with a compound planet gear arrangement
as indicated in the sketch. The motor driving the gearbox has a capacity of 5 kW. The sun has 24 teeth driving
Gear 4 with 58 teeth. Gear 3 has 21 teeth driving Gear 5 having 19 teeth driving the ring gear with 110 teeth.
Determine:
(a) The speed and direction of the ring gear if the sun is rotated by the engine at 300 rpm clockwise and
the arm is locked.
(b) The speed of the arm if the sun is rotated as in "a" and the ring gear at 50 rpm counter clockwise.
(c) The torque available on the ring gear for the case described in "a".
