Multistage Planetary Gears

The planet gears are mounted on a planet carrier and engage positively in an internally toothed ring gear. Torque and power are distributed among several planet gears. The Planetary Gear is a special type of gear drive, in which the multiple planet gears revolve around a centrally arranged sun gear. Planetary gears are used in automotive construction and shipbuilding, as well as for stationary use in turbines and general mechanical engineering. Sun gear, planet carrier and ring gear may either be driving, driven or fixed. 

Features:
Four different transmissions can be configured
Bending beams to measure force
Two-stage planetary gears with three planet gears each
Inductive speed sensors for speed-time diagrams to determine the angular acceleration.

Learning Objectives And Experiments:

Influence of the transmission ratio
Determine reduced mass moment of inertia
Determine the transmission ratio for a locked gear
Determine friction
Determine gear efficiency
Measure transmitted forces for a locked gear
Conversion of potential energy into kinetic energy.
