Screw gears (crossed helical gears)
Screw gears or crossed helical gears are hyperboloid gears that allow the skew mating of the gear shafts!
With the gears considered so far, the axes of rotation are always parallel when...
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...
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...
Bevel gears
In bevel gears, the axes of the gears are at right angles to each other. Bevel gears are used to change the spatial direction of rotation.
Introduction
In contrast to cylindrical gears, where...
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...
Overview of gear types
Depending on the shape of the gears and the type of toothing, gears can be classified as spur gears, bevel gears and worms or worm gears.
The figure below shows a selection...
