About this Product

This is a set of 12 LEGO TECHNIC®-compatible helical gears comprising:
  • 4 left-handed 8-teeth helical gears (median diameter of 1 brick);
  • 4 right-handed 8-teeth helical gears (median diameter of 1 brick);
  • 2 left-handed 16-teeth helical gears (median diameter of 2 bricks);
  • 2 right-handed 16-teeth helical gears (median diameter of 2 bricks);

Helical gears with opposed helix directions can mesh together with parallel axles, just like spur gears.
Helical gears with the same helix direction mesh together with perpendicular - but not intersecting - axles, a little bit like how an official LEGO® worm gear can mesh with a spur gear. However, unlike a worm only being able to transmit torque to a spur gear and not the other way around, power can be transmitted both ways with helical gears.
This allows for many new possibilities with LEGO TECHNIC®.

This is revision 2 of the gears. The gears showcased in the video are revision 1, which did not have the same number of teeth. The new gears work even better!

IMPORTANT NOTE: The plastic will have to wear a little bit before the gears can mesh really smoothly. To achieve that, one has to help the gears rotate together by hand at first, then run the mechanism for some time. This has to be done for both directions.

Please PM me if you want bigger quantities.
