Question
Q7:- Two parallel shafts about 60 cm apart, are to be connected by spur wheels. One shaft is to run at 360 rpm and the other at 120 rpm. Design the wheels if the circular pitch is to be 25 mm. Q8:- An epicyclic gear speed reduction is shown in the Fig. below. The driving shaft carries on the arm A a pin on which the compound wheels B and C are free to revolve. Wheel C meshes with the fixed wheel E and wheel B meshes with the wheel D which is keyed to the driven shaft. The number of teeth on the wheels are:- Zg=27, Z=30, Zp=24 and Zg=21. Find the ratio of the speed of the driving shaft to the speed of the driven shaft. Input output E
