A planetary gear system has a band brake that holds the ring fixed. The sun is driven clockwise at 800 rpm with a torque of 16 N-m. The arm drives a machine. The gears have a module of m =2 mm, and the pressure angle of these gears is 20 degrees. The ring has 70 teeth and planet has 20 teeth.
a) What is circular pitch p?
b) What is the number of teeth in the Sun gear?
c) Sketch the forces applied to the arm and gears
d) What is the output torque?
e) What torque must be applied to ring to keep it stationary?
