The epicyclic gear train consists of the sun gear A which is in mesh with the planet gear B. This gear has an inner hub C which is fixed to B and in mesh with the fixed ring gear R. If the connecting link DE pinned to B and C is rotating at about the pin at wde = 9 rad/s about the pin at E, determine the angular velocity of the planet gear (WB). Note: Do not include the...
The planetary gear system is used in car transmissions. There is sun gear S, planet gears P and the ring gear R. By locking (fixing/grounding) certain gears you can have different gear ratios and 40 mm OR car speeds a) If the ring gear is held fixed, i.e. aR -0, and the sun gear is rotated at ws - 5 rad/s, find the angular velocity, ωΡ。f the planet gears and the output shaft A. b) If the sun gear is...
The planet gear A is pin connected to the end of the link BC. The sun gear D is rotating clockwise at omega_D = 5 rad/s while link DC rotates counterclockwise at omega_BC = 4.8 rad/s. Determine the angular velocity of the ring gear R measured counterclockwise. Express your answer using three significant figures. Enter positive value if the angular velocity is counterclockwise and negative

Part 1 A simple epicyclic gear has a sun gear with 10 teeth and a ring gear with 100 teeth. If the sun gear is held stationary, calculate the speed/gear ratio when the ring gear is the input and the planet carrier is the output? Part 2 Two parallel shafts which are 220mm apart are to be connected by a simple gear train, will all gear centres on the same line, using gears from a pool of six gears of...
The Fig. shows the arrangement of wheels in a compound epicyclic gear train. The sun wheel S₂ is integral with the annular wheel A₁. The two arms are also integral with each other. The number of teeth on the wheels are as follows: S₁=24, A₁=96, S₂=30, A₂ = 90If the shaft P rotates at 1980 r.p.m., find the speed of the shaft Q, when A₂ is fixed At what speed does Q rotate, when A₂ instead of being fixed, rotates...
A compound epicyclic gear train is shown in the Figure. The shaft P is driven at 2500 rpm in the clockwise direction by a motor of power rating 8 kW. The sun S2 is fixed. The number of teeth in the gears are S1, 34; S2, 21; A1, 86 and A2, 73. Determine The magnitude and direction of the angular velocity of the shaft Q and The torque required to fix the sun, S2 A, Q P S, 5,
2. Fig.2 shows an epicyclic gear train in which the internal teeth on the gears A and B have the same diametral pitch. Gear A has 88 teeth and gear B has 100 teeth both internally and externally. The sun-wheel C which is keyed to shaft P has 44 teeth and the pinion E keyed to shaft R has 25. There are floating compound planet wheels F, G. The power input to shaft R is 8 kW at 1440 rev/min....
1. In an epicyclic gear train, as shown in Figure, the wheel C is keyed to the shaft B and wheel F is keyed to shaft A. The wheels D and E rotate together on a pin fixed to the arm G. The number of teeth on wheels C, D, E and F are 35, 65, 32 and 68 respectively. If the shaft A rotates at 60 rpm and the shaft B rotates at 28 rpm in the opposite direction,...
