The helical gear
This gear is used for applications that require very quiet and smooth running, at high rotational velocities.
Parallel helical gears have their teeth inclined at a small angle to their axis of rotation. Each tooth is part of a spiral or helix. The helical gears shown below have splines cut in their center holes. The gears can move along a splined (grooved) shaft, although they rotate with the shaft. An example of a helical gear is shown below.
Double helical gears give an efficient transfer of torque and smooth motion at very high rotational velocities. An example of a double helical gear is shown below.
