Helical Gears
Manufacturing & Exporting Single Helical Gear & Double Helical Gears to Our Valuable Clients
Helical gears offer 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. In the latter, the shafts are non-parallel, and in this configuration the gears are sometimes known as “skew gears”.
Double helical gear has both left- right helical teeth, is used to balance the thrust force and provide additional gear shear area. Also known as Herringbone gears, which resemble two helical gears that have been placed in an adjacent manner. Being double helicals, the thrusts are counter-balanced with no thrust loading on the bearings.
Technical and Design Specification Of The Helical Gears:
- Designed to transmit motion & power between either parallel or right angle shafts (90°, non-intersecting), which rotates in the opposite direction
- Dimensional accuracy
- Durable & ideal for high load applications
- Optimum performance
- helical gears are used in Industrial Gearsboxes, Automobiles, elevators, conveyors, compressors & blowers etc.
- Double Helical gears are placed in V shape as two mirrored helical gears joined together. The mirrored arrangement revokes net axial thrust as each half of gear thrusts in opposite direction.
- To operate in rotational directions, Double Helical gears are extended in two possible arrangements for oppositely oriented helical gears/gear faces, one stable and the other unstable.
