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