Gear pairs

Types of gear pairs:

• Double gear: Two gears with connected teeth; the gears rotate in opposite directions.
• Chain drive: Two gears connected by a chain; both gears rotate in the same direction.
• Bevel gears: Two bevel gears connected at a 90 degree angle; the axis of rotation is altered by 90 degrees.
• Worm and gear: A worm and a gear with connected teeth; the axis of rotation is changed by 90 degrees and the speed is reduced.

Tips for use:

• Move the gears apart to make a longer chain drive or bring them together to shorten the drive. To do this, place the cursor on one of the gears and and drag it to a new location.
• To move the entire chain drive as one group, drag on the chain.
