Gearboxes are used widely in Industrial applications. There are a number of Gearbox Manufacturing Companies in India which manufacture high quality gearboxes. Premium transmission is one of the well-known Gear Manufacturers in India
Helical Gearbox– Helical gears have teeth that are oriented at an angle to the shaft. This causes more than one tooth to be in contact during operation, which makes the gear capable of carrying more load. Due to the load sharing between teeth, this arrangement also allows helical gears to operate smoother and quieter than spur gears.
The modular design and construction of the Helical Gearbox offers several engineering and performance benefits, including a high degree of interchangeability of parts and sub-assemblies. This provides for an economical production, while maintaining the highest standard of component integrity.
Premium transmission is one of the well- known Helical Gearbox Manufacturers in India. Their state-of-the-art manufacturing unit manufacture high- quality gearboxes and other machinery, which find applications in the small- and large-scale industries.
Apart from standard range, Helical Gearboxes are also tailor made to suit individual requirement or as per specifications provided.
- Helical Gears are of different types:
- Double Helical Gear
Double helical gears are a variation of helical gears, in which two helical faces are placed next to each other with a gap separating them. Each face has similar but opposite, helix angles. Employing a double helical set of gears eliminates thrust loads and offers the possibility of greater tooth overlap and smoother operation.
Like the helical gear, double helical gears are commonly used in enclosed gear drives.
- Herringbone Gear
Herringbone gears are similar to the double helical gear, but they do not have a gap separating the two helical faces. Herringbone gears are typically smaller, and are ideally suited for high shock and vibration applications. Herringbone gearing is not used very often due to their manufacturing difficulties and high cost.
- Advantages of the helical gears are:
- They have better teeth meshing and can transmit higher loads, making them suitable for high speed applications
- They are less noisy and produce less vibration
- Offer a larger contact ratio than spur gears
- Transmit large forces and power between either parallel or right-angle shafts.
Most of the reputable Gear Manufacturers in India, suggest helical gears to work under heavy load efficiency and of course when silent operation is needed, such as Automotive applications.
Helical Gearboxes are used in the following Industries:
- Fertilizer industries, printing industries, and earth-moving industries
- Steel, rolling mills, power and port industries
- Textile industries, plastic industries, food industries, conveyors, elevators, blowers, compressors, oil industries & cutters.
Addition to the above applications, there are many others. They find applications in crushers, extruders, coolers, cranes, mixers and conveyors, which are all low-power applications.
The overall application of helical gears and helical gearboxes are widespread.
