Helical Gears – Industrial Application And Types Explained
Helical gears have angled teeth that are cut to an angle to the gear surface, which is known as the helical angle. It has a very good contact ratio because of its angled teeth that engage more in gradual contact with the shaft axis. It can transfer a large amount of force and provides smooth and noise-free applications. It has great load capacity and better tooth strength.
It can transfer power from both parallel to nonparallel shafts. It will run at a slow speed to moderate speed with very less noise and vibration as these gears are exhibited to axial thrust, which can correct by lubricant and thrust bearing. In helical gears, all loads are branched out in the teeth of this gear.
Different Types of Helical Gears And Their Uses
- Single Helical Gear: Single Helical Gear has teeth on one of the helices, either on the right helix or on the left helix. Single helix gear develops centrifugal force, and the power transmission capacity of this gear is low. You can’t expect high precision when working with his single helical gear. Single helical gear generates high thrust load because of that the helical angle of this gear varies from 15-20 degrees.
- Double Helical Gear: Double helical gears have two identical teeth on both sides of the axis. There is no thrust force and axial load on the axis, so the helix angle varies from 20-45 degrees. It transmits large power. The efficiency of the double helical gear is large as compared to the single helical gear. It is also known as herringbone gears.
- Crossed Helical Gear: Cross Helical gear is often called screw gear. It is designed to transmit motion at a 90-degree helix angle. Crossed Helical gear allows skew mating of the gear shafts. It is best for transmitting low power. It has a higher load capacity. It is the perfect choice for conveyor belts and elevators. It can be used for both parallel shafts as well as for nonparallel shafts.
Industrial Uses Of Helical Gear
Helical gears are mainly used in the automotive sectors for making the gear arrangements of four-wheeler and two-wheeler vehicles. It is suitable for high-power transmission and generally used in cranes, turbines, and marine drives. They are widely used in high-speed applications where there is a need to transmit high power from one shaft to another.
Helical gears are best for industries that deal in power transmission, and they can buy good quality gear from a trusted Helical Gear manufacturer. However, in India, gears manufactures in Punjab Ludhiana manufacture high-quality helical that can be beneficial for various industries that increase their efficiency and production.
Helical gear is one of the most important innovations of humans that is bringing a revolutionary change in the manufacturing industries because they are capable of transferring a good amount of force or power. So, go with the best and most reliable helical gear manufacturer to smoothly perform your operations with different types of machinery.
