1. The picture below provides a diagram of a planetary gear set. 2- 3 1 W2 4 The gears are labeled as follows: Sun gear: 1, Carrier: 2, Planetary Gear: 3, Ring Gear: 4. The gears have a diametral pitch of 32. The sun gear has a pitch circle diameter of 4.0 inches. The planetary gear has 112 teeth. The ring gear has a pitch circle diameter of 11 inches. The ring gear is the output gear, and the sun gear is fixed. The carrier is the input. a) (5 points) Calculate the pitch circle diameter of the planetary gear. b) (10 points) Calculate the angular velocity ratio between the output gear and the input carrier. Use the method discussed in the course notes. c) (10 points) Calculate the angular velocity and the direction of rotation of the output gear if the angular velocity of the input is 120 rpm clockwise. Use the method discussed in the course notes. d) (10 points) Two planetary gear trains, that each have the parameters stated above, are assembled together, such that the ring gear shaft of the 1st planetary gear set drives the carrier shaft of the 2nd planetary gear set. Determine the angular velocity and the direction of rotation of the ring gear of the 2nd planetary gear set if the angular velocity of the carrier of the 1st planetary gear set is 100 rpm clockwise. 1.
