Hint L10 - Gears

Some K'NEX sets come with K'NEX gears. They can also be bought separately as parts in our Technology 2 enjoy K'NEX shop.

The gears enable a turning motion in one K'NEX rod to be transferred so as to become a turning motion in a second, parallel K'NEX rod.

L10d

Some K'NEX gear wheels have teeth that extend beyond the surface of the wheel. These are known as "crown gears". This allows the gear wheel to also transfer a turning motion from one K'NEX rod to another K'NEX rod at right angles to it.

L10e

The red and yellow gears in the photos above are the same width, 55mm.

A much larger crown gear is also available, 130mm in diameter, as shown in the photo opposite.

L10b

If you do not have any K'NEX gear wheels, a gear wheel may be made by putting 8 green rods into the 8 slots on a white connector. Two such wheels may then be used in combination, either to transfer motion between two parallel rods, or between two rods at right angles to each other.
