Double Helical Gears are the Combination of left-handed as well as right-handed helical gears. These have the same twist angle with providing better stability and transmitting rotational motion between the 2 parallel shafts. Double helical gears are quite beneficial compared to helical gears. These gears are stronger and quiet to combine the helical gears on their right and left-hand twists.
Normally, Double helical gears along with the herringbone gears are quite similar to the groove in the center. These are called the double-helical gears. Herringbone gears do not have the groove in which the left and right teeth meet in the center.
Benefits Of Double Helical Gear:
Normally, the Double Helical Gears would nullify or counteract the force for overcoming axial thrusts. The total face will be made in equal halves and both of them have a similar helix angle. Axial thrusts are opposite to one another so these forces are contained in gear. The force will not be transmitted in bearings during the heavy impact.
Below are the benefits of using Double Helical Gears such as:
- High load capacity
- Suitable for heavy-duty applications
- Increased reduction ratio with comparison to worms gears
- Teeth are two opposite sides of the gear and provide a reduction ratio of 1:2.
- Produces low noise
- Fewer parts compared to worms gears
- Efficient than worm gear
- Used with parallel and non-parallel shafts
- Manufactured by spiral-shaped surfaces on single gear
- Easier on cutting curves
- Smooth gear operations
- Simple and easy to use
- Economical choice
Manufacturing Process:
Double Helical Gear can be manufactured using various machine tools like Shaping Machines and Gear Hobbing. The manufacturing method of double-helical gears can also be done using CNC machining. This method has the advantage of tooth surfaces being modified arbitrarily and it is easier to make the machine settings. Hole and blank diameter can be also machined so the CNC machining center is based on a computer-aided manufacturing system.
