Helical gears play a crucial role in aircraft systems, including engines, landing gear, and control mechanisms, where reliability, precision, and efficiency are paramount. The growing air travelling has increased aircraft production and deliveries owing to which the need for high-performance gear systems like helical gears has surged. According to the General Aviation Manufacturers Association, in 2022, aeroplane shipments demonstrated positive growth compared to 2021. Piston aeroplane deliveries increased by 8.2% (1,524 units), turboprop aeroplane deliveries rose by 10.4% (582 units), and business jet deliveries slightly increased from 710 to 712 units. The total value of aeroplane deliveries in 2022 amounted to approximately $22.9 billion, reflecting a growth of around 5.8%.
The Asia Pacific region has emerged as a leader in the helical gears market owing to its robust manufacturing capabilities, expanding automotive sector, and increasing investments in automation, countries. According to the International Trade Administration, In 2020, the Korean government invested $414.4 million in research and development projects to encourage SMEs to enhance and expand their automated technologies. Additionally, China's domestic automotive industry is projected to reach 35 million vehicle production by 2025. In 2021 alone, the country witnessed, over 26 million vehicles sold, including 21.48 million passenger vehicles, marking a notable 7.1% increase compared to the previous year.
While helical gears offer numerous advantages, they may not be suitable for certain applications that demand specific gear characteristics. For instance, in applications requiring high torque transmission, helical gears may face limitations due to their inherent axial thrust and load distribution characteristics. Similarly, applications that demand low backlash, such as precision machinery may require alternative gear types that can achieve tighter tolerances. These limitations can restrict the widespread usage of helical gears in these specialized applications, necessitating the exploration of alternative gear solutions that better align with the specific requirements and constraints of these industries.
