Program description:
YP Planetary Gear is designed to assist teachers and students when they
study the working of a planetary gear train. (this software is not related
in any way with astronomy).
A planetary gear train is a mechanism consisting of an assembly of meshed
gears: the sun gear, the planet carrier, and the ring gear. The automatic
transmission in an automobile uses the planetary gear train to transmit
power from the engine to the wheels at various controllable speeds and
torques. The transmission of power is varied by locking one or the other
of the three gears.
With YP Planetary Gear, you may observe the motion of a planetary gear
train when one of its parts is locked. The program also calculates the
ratio of the angular velocities when one of its parts is locked.
Required Hardware and Software: YP Planetary Gear runs on any Macintosh
computer with MAC OS 7.0 or later. It needs about 900 Kb on your hard disk
and 800 Kb of RAM. The software runs on older models with 68000 processors
(Mac Plus, Mac Classic), but simulations are slower.
