Internal Gear Pinion Drive
Product Code : EL-DOMLE-10782
Internal Gear Pinion Drive (code EL-DOMLE-10782) is a hand-cranked teaching model for demonstrating the basic working of an internal gear and pinion drive. Made of metal and plastic, it is an open system held between two clear plastic plates so the meshing gears can be studied, with 2 dials to show rotation, and it stands on a base as a bench top or desk top item.

What Is the Internal Gear Pinion Drive Used For?
In an internal gear drive the pinion meshes with teeth cut on the inside of a ring gear, so both turn in the same direction, unlike two external gears in mesh, which turn in opposite directions. Students turn the crank handle and watch through the clear plates as the pinion runs inside the internal gear, while the dials show the rotation. Comparing the motion of the pinion and the internal gear lets them see the direction of rotation and the change in speed for themselves, on a model small enough for a desk.

Frequently Asked Questions
What does the Internal Gear Pinion Drive demonstrate?
It demonstrates the basics of an internal gear and pinion drive, with the pinion meshing inside the internal gear in an open system that can be studied closely.
What is it made of?
The model is constructed from metal and plastic and is sandwiched between two clear plastic plates, so the gears remain visible while they turn.
How is rotation shown?
The model has 2 dials that show rotation as the crank handle is turned by hand.
Where is the model used?
It is laid out on a base as a bench top or desk top item, measuring approximately 400 × 200 × 300 mm and weighing 5 kg.
In which direction do an internal gear and its pinion turn?
They turn in the same direction, because the pinion meshes with teeth on the inside of the gear; two external gears in mesh turn in opposite directions.
