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...
Spur gears (straight-cut gears)
Straight-cut gears (spur gears) are the simplest type of toothing. In a spur gear, up to 3 teeth are in mesh at the same time.

If the teeth of a toothed gearwheel...
Helical gears
Helical gears have a lower noise level and can transmit higher torques than spur gears!
https://youtu.be/iYZR8oAr0cY
When it comes down to reduce noises and transmit high torques, helical gears are often used. With...
Hypoid gears (screw bevel gears)
With hypoid gears, rotary motions between non-intersecting axes can be realized!

With the bevel gears considered so far, the axes of the ring gear and pinion intersect at a certain point. In...
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...
