We manufacture and supply Helical Gear or “dry fixed” gears which offers a refinement over spur gears.
The leading edges of the teeth are not parallel to the axis of rotation, but are set at an angle. Since the gear is curved, this angling makes the tooth shape a segment of a helix. Helical gears can be meshed in parallel or crossed orientations. The former refers to when the shafts are parallel to each other; this is the most common orientation.
The angled teeth engage more gradually than do spur gear teeth, causing them to run more smoothly and quietly. the use of helical gears is indicated when the application involves high speeds, large power transmission, or where noise abatement is important. Read more.
