Question

(a) Based on the arrangement of epicyclic gear train shown in Figure 1, draw the schematic Levai's diagram. \newline [Berdasarkan susunan rangkaian gear epicyclic dalam Rajah 1, lukiskan diagram Levai skematik.] \newline (4 Marks / Markah) \newline (b) Figure 1 shows an epicyclic train with its tooth numbers. The arm is driven counterclockwise at 50 rpm and gear A on shaft is fixed to ground. Find speed of gear D on shaft 2. What is the efficiency of this train if the basic gearsets have $E_o = 0.96$? Next, if the speed of the shaft 2 has to be increased to 20%, design the gear system with the same arrangement as above. \newline [Rajah 1 menunjukkan sebuah rangkaian gear epicyclic dengan bilangan giginya. Lengan digerakkan berlawanan arah jam pada 50 rpm dan gear A pada aci dipasang ke tanah. Cari kelajuan gear D pada aci 2. Apakah kecekapan rangkaian jika set gear asas mempunyai $E_o = 0.96$? Seterusnya, jika kelajuan aci 2 harus ditingkatkan sehingga 20%, rekabentukkan sistem gear dengan susunan yang sama seperti di atas.] \newline (16 Marks/ Markah)
