The versatility of non-modular gears, designed with the HSG theory, allows them to be used in different areas of sustainable mobility including: land, marine and above all aeronautical transport. This type of toothing offers various advantages in terms of smaller size and weight, greater energy efficiency and reliability.

Gears designed with HSG theory can handle high gear ratios without, among other things, the need to modify the wheelbase, offering a flexible option to adapt to different transmission needs, i.e. rotation speeds characteristic of different mobility sectors.

The application of HSG gears is particularly suitable in the context of the current energy transition in which we are witnessing a rapid transition towards electric traction. In fact, electric motors, especially those with high rotation speed, require a high reduction ratio (e.g. 10:1, 13:1 16:1 etc.) which is sometimes already available on the market, but often has multiple transmission stages to adapt to the desired output speed.

However, with HSG gearboxes, high gear ratios can be achieved with a single step, avoiding the need for multiple speed steps in cascade. This not only simplifies the design of the transmission system (less weight and less space), but contributes to the reduction of energy losses associated with multiple transmission stages, also significantly reducing critical issues related to lubrication and/or maintenance.

A further advantage of the gears designed with the HSG theory concerns the versatility of use, in fact, it is possible to modify the transmission ratio while keeping the center distance unchanged and therefore the geometries of the case and the supports simply by replacing a pinion

This flexibility is invaluable in a context where transmission needs can vary depending on specific applications.

In summary, HSG gears offer an innovative design and deployment approach to address the challenges related to power transmission in high-speed electric vehicles and can contribute to improving energy efficiency linked to a reduction of emissions in the sustainable mobility sector ( automotive, aeronautics and naval).
