7. Figure 5 shows an epicyclic gear train with the following details: A has 40 teeth external (fixed gear); B has 80 teeth internal; C-D is a compound wheel having 20 and 50 teeth (external) respectively, E-F is a compound wheel having 20 and 40 teeth (external) respectively and G has 90 teeth (external). The arm runs at 100 rpm in clockwise direction. Determine the speed for gears C, E, and B. [ Ans. 300 rpm. clockwise; 400 anticlockwise; 150 rpm. clockwise]

Step 1
In an epicyclic gear train, one or more gears orbit around a central gear. The speed of each gear in the train is determined by the number of teeth on each gear and the speed of the arm. Show more…

In an epicyclic gear train, as shown in Fig.13.33, the number of teeth on wheels A, B and C are 48, 24 and 50 respectively. If the arm rotates at 400 r.p.m., clockwise, find : 1. Speed of wheel C when A is fixed, and 2. Speed of wheel A when C is fixed.

Q14: An epicyclic gear train, as shown in the figure below, consists of two sun wheels (A) and (D) with 28 and 24 teeth respectively, engaged with compound planet wheels (B) and (C) with 22 and 26 teeth respectively. The sun wheel D is keyed to the driven shaft, and the sun wheel A is a fixed wheel coaxial with the driven shaft. The planet wheels are carried on an arm (E) from the driving shaft, which is coaxial with the driven shaft. Find the velocity ratio of the gear train. If 1 hp is transmitted and the input speed is 100 rpm, determine the torque required to hold the sun wheel A stationary.
