Helical Gearboxes is the type of gear system
in which the leading edges of teeth instead of being parallel to the axis of
rotation are set at an angle to the face of the gear. Since the shape of the
gear is curved, these gears look like a segment of helix. When two helical
shaped gears engage, the contact initiates at one end of the tooth and
progressively spreads until the gear combination begin to rotate. Due to
this, the whole operation is more smooth and quiet than it is in spur gears.
Being meshed in parallel or crossed orientations, these gears are able to
create thrust load. These helical gears together with spiral or helical
shaped gears provide excellent accuracy, surface finish and long running
characteristic. Being intricately made up of alloy or stainless steel these
gears bear resistance against wear and fatigue. This gear system can be
easily installed in difficult conditions owing to its high power to weight
ratio and low volume.
- Horizontal variant
- Vertical variant
Horizontal units have optional
right or left hand shaft arrangements from the same sub-assemblies and are
available as foot mounted shaft mounted or
foot/shaft mounted types.
Vertical unit are availed in three
versions: Standard units, heavy duly stirrer types and cooling tower drives.
