Worms and worm gears
With a worm gear, high loads can be transmitted at a high transmission ratio.

Operating principle
A special design of the gear wheel is the so-called worm. In this case, the tooth winds...
Rack (toothed bar)
Racks (toothed bar) allow the rotary motion of a spur gear to be converted into a straight-line motion of the rack.

While only rotary motions occur with conventional cylindrical gears, a rack...
External and internal toothing of gears
With internal toothing, the center distance to an externally toothed gear can be shortened.

For cylindrical gears, a basic distinction can be made between external gears and internal gears. In the case...
Herringbone gears and double helical gears
Herringbone gears combine the advantage of helical gears (high load capacity) with that of spur gears (no axial forces).

Herringbone gears
In order to combine the advantage of helical gears (higher load capacity...
Helical gears
Helical gears have a lower noise level and can transmit higher torques than spur gears!

When it comes down to reduce noises and transmit high torques, helical gears are often used. With...
Screw gears (crossed helical gears)
Screw gears or crossed helical gears are hyperboloid gears that allow the skew mating of the gear shafts!
