What do you need to know about helical gearboxes?

The major applications of industrial gearboxes are those involving speed change, direction, and torque between a normally working motor and a shaft driving a piece of equipment. They are unique among the primary industrial gearbox manufacturers and suppliers in India.

Helical Gearboxes The teeth of helical gears are cut at an angle to the shaft. As a result of this, during the operation, more than one tooth will be in contact, and hence this gear becomes capable of carrying more loads. This arrangement also allows the helical gears to run more smoothly and quietly than the spur gears because of the load sharing between teeth.

The modular design and construction of the helical gearbox provide a number of engineering and performance features that give this unit a high degree of parts and sub-assembly interchangeability. This provides a basis for economical production while still maintaining very high standards of component integrity.

The helical gearbox is one of the most used gearboxes, and it is more productive than other gearbox. This arrangement facilitates many operations.

Why Helical Gears?

• The angled teeth of a helical gear engage more gradually than spur gear teeth so that they can run more smoothly.
• Helical gears and helical gearboxes are very robust and suitable for high-load applications.
• It can transmit motion and power between parallel or right-angle shafts.
• Helical gearboxes are the most efficient gearboxes to date produced by the industry and function with 98% efficiency, just behind planetary gearboxes.
• Generally, there are broad applications for helical gears and helical gearboxes.

Advantages of Helical Gearboxes

Higher Efficiency : In general, helical gears and helical gearboxes have a common wide use. In the helical spur gear design, the high number of teeth engaged rationally promotes a minimum level of friction and an associated minimum-dissipated energy loss in the transfer process. This results, in turn, in high efficiency and reduced energy use overall.

Smoother and quieter operation : This will, besides, provide smoother and quieter operations. Since the teeth are angled slightly in helical gears, tooth engagement is gradual, and hence the noise and vibration levels are low. This makes the gearboxes quite suitable for applications where noise reduction is important, like in manufacturing facilities or noise-sensitive environments.

Greater load-carrying capacity : Helical gearboxes are more load-intensive compared to gearboxes. With the angular orientation of teeth, it is possible to have multiple contacts at a time; hence, the load is distributed over a larger contact area. Hence, such gearboxes have improved torque transmission capacity and can take higher loads without compromising performance.

Improved Torque Transmission : It is believed that the helical tooth design develops a larger contacted area, which meshes with more teeth at one time. Such a feature is of paramount advantage in heavy-duty applications where high torque needs to be transmitted, for instance, conveyors, crushers, and mixers.

Better alignment capabilities : Helical gearboxes have high shaft misalignment capabilities compared to worm gearboxes. The gear design is usually such that small misalignments between the input and output shafts do not significantly impact performance, hence easy installation with reduced maintenance time. This, in turn, reduces the amount of effort required in the assembly process for precise alignment.

Benefits of Helical Gearboxes

• Fertilizer industries, production businesses, and earth-moving industries.
• Rolling Mills, Steel Power, and Port Industries
• They are applied in textile industries, plastic industries, food industries, conveyors, elevators, blowers, compressors, oil industries, and cutters.
• Then there are crushers, extruders, coolers, cranes, mixers, and conveyors, all low-power applications.
