Planetary Gear

Aim- Modelling and motion analysis of planetary gears

Geometry modelling-

Sun gear-

planter gear-

ring gear-

carrier-

Assembly-

-------------------------------------------------------------------------------------------------------------------------------------------------------------------

Motion analysis setup

1) Solidworks motion is enabled and motion analysis is opted

2) A motor is set to the axis of sun gear at 200 rpm.

3)contact forces are given as follows-

i) sun gear- all the planet gears.

ii) all the planet gears and ring gear

iii) carrier and ID of gears at contact.

4) Gravitational force is set in Y axis.

5) Results are calculated accordingly.

Results and plots

Angular velocity of sun gear-

It reamins contant at a magnitude of 2250.000131rad/sec

contact force between sunngear and planet gear

It gradually drops down from a value of 593.7561823N

Angular velocity of planet gear-

Angular velocity drops down from 600 and there by hits a peak of 120.977 rad/sec.
